4.0 OHV Don't like Oil.

[koldstart]

Maybe thicker oil will resolve the problem because the parts have the extra lubrication. Maybe there isn't a problem, and it's normal operation of the engine.
I don't know for sure, and that why I'm here. Either way, eliminating the sound will make me feel better

I did a few Shucks/Autozone/FORD runs today, trying to find out more infromation and I found out a fairly reasonable suggestion. Maybee one of you can chime in on it. --

New oil has alot of additives in it, and there could be some blockage inbetween where the oil needs to run througout the motor, leaving certain areas with less oil then desired. After the oil has broken down, it moves through around better and is able to get into those harder to lubricate areas.

His solution was a engine FLUSH, removing any build up and blockages anywhere in the engine. With 10w-40 oil ( ñòóKýçrÕôK advice ) and a good quality oil filter.

what do you think of them apples?

 

[briwayjones]

I'm no expert but that doesn't sound like a plausible explanation to me. If brand new 5w-30 synthetic oil doesn't get to it, nothing is.

 

[koldstart]

Well, just did what that guy said. Still have the noise. Another 20$ down the tube.

Koldstart, i was just listenening to your motor sound a few more times and i dont know how close you where to the motor but i dont think mine was that loud. Maybe you do have internal issues. Again just like a few other members stated it might be time to stop spending the money at least for the oil and bring it to a mechanic and see what he says. From my experience if you had any issues with low oil pressure for what ever reason clogged pump or bad pump you will hear more of the top of the engine then the bottom half. Like a bad TAP from the lifters. The things i have done to my truck and have seemed to help ALOT, matter of fact this morning i had no sound. castrol 10/30 oil, tried mid grade gas 89 octane used about a half tank so far and did sea foam through the brake booster three times. I do have the CEL on and it is running lean and i need to look into that but a friend of mine who knows about cars stated maybe becasue it is running lean the timming is so far advanced it knocks. I really wish you were closer to me so i could hear it in person and compare it to mine but like i said mine is almost gone. I stated above what i have done and if i do hear a little here and there i am going to live with it becasue it is minor. Plus i posted the bullentins that ford said about the OHV motor with marble sounds and knocks so we are probably not the only people that have the sound.

I hope you get it resolved soon and please keep us posted on the outcome. I will still keep my eyes and ears open if i find anything else that might help you.

If you go with thick oil it will hide the sound. You are trying to resolve the issue not hide it. I have also read that someone used synthetic and it went away. As for the oil filter that is not going to change anything. Of course dont use a crap one you want it to filter and clean the oil but to change that sound negiative it wont matter. I use fram and i love them. Used them on all my cars and never encountered an issue. I would recommend starting off with seafoam and using the recommended oil from the dealer. the weight and everything. If it doesnt work after about a week put some thick crap oil in it and sell it back at auction. I also noticed that i used super the day before i changed the oil and someone told me that could also give you a knock. The car manual even states that. Low octane can give you a knock and so can high octane.

Back to drawing board.

My 2000 Sport with the OHV engine did the same thing to me at 20,000 miles. It was quiet when I changed to new oil, and within a day, I got that knocking sound. My local Ford dealer showed me a TSB that this "Marbling" sound is normal. My dealer suggested that I switch to a full synthetic oil. They recommended Mobil 1 and even drained the new oil out and put in the Mobil 1 for me a no charge. Sure enough, after 1 full day of driving, the sound went away and I have not heard it since, even while idling inside of the garage. That was at 20,000 miles, I now have 65,000 miles on it and have only used Mobil 1 and Motorcraft oil filters, and the truck is STILL quiet! Mobil 1 is not at fault with your knocking. I live in Iowa, where in the winter it gets WELL below zero for days on end at times, and in the summer gets hot as hell, with 100+ degrees along with high humidity, and Mobil 1 (actually I use Mobil 1 Truck) handles these extremes perfectly, and I use the recommended oil weight that is on the sticker of the truck. You may have other motor problems going on, maybe, but I don't think Mobil 1 is at fault. There is also no need to add ANY kind of oil stablilizer with Mobil 1, your wasting money and possibly causing more harm than good.

TY so much for that. That is the exact same thing I said. The ONLY reason I suggest STP Oil Treatment is for higher mileage engines (say 85,000+ miles). It is proven to preserve valve integrity and even helps quiet noisey valves (which is the only reason I'd suggest using it at all). New oil is as stable as it gets. Why would you need a stabilizer for new oil?

 

[koldstart]

Ok, well it's allready starting to become less of a problem. Im sick of oil changes for now, next time I will get full synthetic with a motocraft filter and revive this thread when I do and talk about the effect.

Thanks for everything up to this point.

 

[dalefanatic38]

my 99 ohv is doing the same thing. off idle nothing. at idle it sounds like a mack truck. i use castrol syntec 5w30. i have used this oil in all my cars and truck.

Koldstart, from the testing i have done it seemed to help me alot. The noise is about gone. This is what i have done and maybe it cane help you. I got away from the continues oil changes. I have currently 10/30 castrol with the lucas oil additive in it. I have done the following in the last three days and it seemed to help.

1) Seafoam about 4 times so far through the brake booster.
2) throttle body cleaner through the intake with the truck off. Did about 1/3 of can about 30 seconds of spraying through the intake throttle body flap.
3) 89 octane of gas with the lucas gas additive. I bought the big bottle so every 10 gallons or more i add 3ounces.

Currently i get the sound minimal at cold start in the morning for about 5 minutes but the truck is running to lean. I have the check engine light on and i have the codes "running to lean bank 1 and 2 and i think becasue of that i might be getting that little minimal knock sound when cold.

I hope this helps you in some way. I think it is more carbon in the motor that is causing it. I did speak to my friend who is in to cars and he said he heard that GUNK came out with a additive you add in the oil for 5 minutes with the truck running and then you change the oil. What it does is remove all the carbon build up. I was going to try that in a few weeks if it gets worse.

Keep us posted.

Im courious as to what happened. I just bought a 2000 XLS 4.0L V6 OHV with 66000 miles on it. Had it about 2 weeks so today i decided to give it an oil/filter change, plugs/wires, fuel filter, grease everything and get a real good look at the truck. After i changed the oil (used valvoline max life 10w30 and a motorcraft filter) i get that marbleing sound you all described. Plugs are motorcraft w/.054 gap.

sound only happens at idle. drove it about 20 miles and it was gone when i pulled into the gas station. after getting gas (89 oct) started it back up and drove home (1/2 mile) got out and the marbleing sound is back.

It runs fine, no roughnes or any other signs of trouble just that darn marble sound at idle and you can only hear it if you get down to look under the vehicle.

So what did you all find out?

If you look at the other two pages of this thread you will see what i found out on car complains .com. It is a sound ford knows about and have stated nothing really to fix it. Get some seafoam and run it through the brake booster and intake. Do a search for seafoam and you will find out more about it. It has helped me alot but the sound is still there in the morning. I plan to run more seafoam when i have a chance to pick it up at the store which is 40 minutes from me but as of now the truck runs great and i am dealing with the minor marble sounds.

I did read somewhere now that i remember that ford had something that the dealer mechanics would run through the motor to break up all the carbon and it helps but i never really did more research on it.

If you find a solution please share it....

How about.... pre-detonation problems. With the new oil, it is likely (hopefully) that you have improved compression ratios on your cylinders.. However, maybe your timing (computer controlled) are "set" based on over time measurements/adjustments on your old oil. Maybe those are too advanced at idle for your new oil and as a result you are getting a "form" of pre-detonation... not really more like too advanced timing for your compression ratio. That's my story and I like it...

 

[X-North]

ok guys...im newbie at this term but was Seafoom cleaning is ????
For my part I unbolted the aircleaner tube and put directly in throttle body while running a complete can of brake cleaner...it clean you maf and iac and all intake. For the carbon i do something crazy ....when the fuel tank is nearly empty ...under the red line I put a 4 litres of Acetone in the fuel thank. Thats smell real bad but when you see the particles coming out out the tail pipe you know it clean

My 99 XLS got a re-man Jasper engine at 112,000 miles. It now shows just over 120,000 miles. The new Jasper engine has made the "marbling" sound since day one. Nothing to worry about.

 

[X-North]

Jasper....in canada thats a realy cheap brand name for poor brakes

Oh i NEVER said it was at fault. I think the viscosity is. I had 5w30 blend in there, and it did it, i switched to 5w20, and it went away. I just said the quaker state because thats whet i have. the 5w30 it not the right winter oil. I think its the fact its 5w30, not mobil 1. ive used that before too, and think its GREAT oil. I just decided to try this new stuff for fun, and i like it just as much. IM saying keep synthetic, do not switch back, use a lower # like 5-20 for winter!

Just to add. Mobil 1 oil is known to shear under hard usage. If you are running 5w-30, after a while it becomes more like 5w-20. When this happens, oil flow will be different and it might explain why your sound goes away. This means that if you use 5w-20 you should not have noise to start with. Now, it does not explain why you have noise. I just suggest using 5w-20 oil to reduce noise, nothing more.

PS. Most oils will shear. Synthetic oils are better than dyno oils, but they all shear with time.

That's a great cando attitude. Maybe a little overboard on the oil purchase there but hey. Believe me when I tell you I've worked on cars since I was hip high to a grasshopper (still aint much taller than that now) lol. My father picked me up because I was too small to climb up under the hood of our Mustang when the motor needed changed and I cut hoses and wires loose for him. I know what I'm talking about in most cases. You will have to do what's right for you in the end but if you can buy the oil thick enough without Lucas I'll beg you not to use the Lucas oil treatment again. New oil is plenty fine without additives. I do however recommend STP oil treatment for higher mileage engines because it helps keep the valve seats strong and sealing good and for that reason only. Certain oils and additives are very high in detergant (I think that's what it's called) These oils and additives clean old oil and gunk off the inside of your block and dump it all in the pan. It's very possable this is happening to you when you change your oil. After a period you say it stops the noise. I imagine it's when all the deposits dissolve and run through your oil filter. It's very possable your additive (Lucas) and oil could be doing more harm then good. There should be a place on the bottle to check detergant level in the oil. Again not sure that's what that's actually called. On a new motor high detergant oils are ok to use as long as you only use that. Older, higher mileage motors that have had nothing but low or mixed detergant level oils used get gunked up and damaged enough by that then get high detergant oils used, wash the gunk down, then end up pulling it into the oil pump and filter and can eventually clog them up. I do hope some of this helps you decide.

Lucas Oil Additive also helps with Valve seals and such. I am using the Lucas Full synthetic. I also noticed the same noise upon startup. But now I am having a bigger problem. My Oil pump has since let go and I am having to replace it. Going to be along weekend and cold 0 windchill in the driveway on my back. Hmmmmm anyone have any thoughts or ideas on making it easier?

 

[Razzierb]

This is interesting stuff. I had an 03 4.0 Explorer and ran Mobil 1 from the start. I traded for an 05 with a 4.0 and just moved to Mobil 1 5W30 this afternoon (from what I presume was standard 5W30 mineral oil). What I thought I heard was more like a exhaust manifold leak, but marbling seems to describe it too. Happens at idle. Mine has 23K on it and is still under warranty.

I'm gonna disconnect the battery for awhile and then restart. I saw the pre-det comments related to the oil ... and who knows. The 4.0 remains one of the few Ford / Honda motors that 5W20 is NOT the recommended oil ... HOW COME ...?? Even my 2002 3.0 Ranger calls for the lighter Visc. oil

Any ideas as to why? I'd never thought about it, but now, I've got some sort of noise .. VERY ODD .... I'm betting on the electronics ... Otherwise .., why all the sudden ...? I didn't all the sudden develop heavy carbon on my pistons with a 23K motor.

Oil Issues

Hi Everyone

Years ago I used to work part time for this old timer mechanic who had a engine rebuilding shop. Back in the 80's when the v-6's were becoming popular, he used to always complain about how the auto manufacturers were saying to use light weight oil for thier motors. I can remember a good part of his business was rebuilding these motors. He would say that the oils wre too light, and causes the motors to "slap apart" . Since then, I always use Pennzoil 10w-40, and never had a problem. On my 99 explorer, I change my oil every 2500 miles, and use 4 qts of pennzoil 10w-40 with one quart of lucas oil stabilizer. My Explorer gets 14 mpg around town, and 25 highway, and it has 108k miles on it, and the motor is very quiet. I frequently tow a 14 ft. fishing boat with it, and a trailer that carries one quad, and two dirt bikes. All I can say is the heavier oil has always worked for me, even in the winter . Hope this might help. Good luck !!

Marbling noise!!!

Just found out myself why I was having a problem. Lost all oil pressure Pulled it apart thinking it was the Oil pump, wasn't. It was the pump screen, the engine had builtup so much carbon it was falling into the pan and being pulled into the screen. Keep in mind I do 3000 mi. oil changes and also use Mobil 1 with Lucas Full synth. additive. Needless to say I changed the pump anyway since I had the pan off. What a job that is while it is in the vehicle. So we'll see what hyappens from here. Hopefully no damage done.
