ohv

Hi, I just did a smoke test on my Explorer searching for a possible vacuum leak. The only place that smoke escaped was near the knob on the idle air control valve. Is this the vacuum leak or is it normal for smoke to escape from the valve when the vehicle is not running? Thank-you in advance.

i was wondering if anyone had drilled and tapped the back sides of the lower intake manifold. i was curious about adding a coolant crossover since the rear passages always seem to have more gunk or just blocked up.

Hello, First post here so if I leave any details out please ask. I have a 97 AWD Explorer with the 4.0 OHV Engine, and I've been struggling to figure out what's wrong with it. It randomly shuts off while the RPM's are low. It will do it when slowly approaching a stop light, or while just...

Hi I just bought this 2dr 1996 Sport 4.0 ohv. some background info, skip down if you want. it has 134k miles, has maintenance records back to when they bought it. The truck was given to his son who I think started doing IMO (but, I'm also uneducated in this) dumb modifications. He wired a stereo...

From the PNW, I travel to the east side a lot and needed this for the pass. 2DR sport, 130k miles on the 4.0 OHV; I'm the 3rd owner but the 2nd owner was the son of the original owner who maintained it since he bought it new in Colorado. Really clean! Does anyone know where to find parts...

How's it going guys. I've started to plan a top end rebuild as I have low compression on cylinder 3. About 60 pounds cold/dry and 70 pounds cold/wet. The rest tested 150-160. I consider having my head worked but one is a 95tm and one is a 98tm on my 98. This lead to me to simplify the process...

I need to replace my upper intake gaskets that are leaking. I looked in my old Haynes manual and these are the torque specs. They seem kind of low with the upper intake nuts torqued to 12 ft lbs. While the studs to the block are torqued to just 84 inch lbs which is 7 ft lbs. The other torque...

Can anyone tell me how many times the camshaft syncroniser rotates for every revolution of crankshaft harmonic balancer? If I'm not mistaken is it 2 times? This would be on a 4.0 V6 OHV (NON-SOHC) I feel stupid. I rebuilt this 97 ranger engine and the timing chain was set at 6 and 12...

2000 explorer 4.0 ohv manual transmission 5 speed My explorer has a total of 3 oxygen sensors 2 upstream one downstream after the cat. The downstream sensor was hitting my exhaust and burned/cut a wire from the sensor. My question is should I solder heatshrink it? Or should I just replace. Also...

I’ve got the infamous camshaft synchronizer squeaking sound on cold starts. I had a shop replace the lower intake and camshaft synchronizer gaskets last week and the truck has developed a squeaking sound in the rear of the engine. I took the belt off and the sound is still there. The mechanic...

Have a question working on a project with 2 1998 Ford explorer 4.0 V6. One is OHV (x-vin) 4x4 automatic xl, engine runs great but body is full of rust and is being put aside for future project. I picked up another 1998 4.0 v6 4x4 xlt from South Carolina. It didn't have an engine but it is set...

A couple of years ago I got the idea of replacing my throttle position sensor since it was the stock part. I gave up after rounding the philips screws. I then tired to use a dremel to cut a slot into the screw heads but that didn’t work out too well. Recently, my absolute throttle position...

I just purchased a 98 explorer xlt sans engine, Stock it had the 4.0 sohc. I have a 98 xl with 4.0 ohv. My ohv is still running strong but the NY salt ate her body all to hell. The sohc is from South Carolina and is rust free. I want to put my ohv in it. Here is my conundrum, when it comes...

Solved: The part number you’ll need is F87Z-5E269-DC. I’m replacing all of the bushings and hangers on my exhaust and the only one I’m missing now is the one that bolts onto the transmission area. Does anyone know if you just remove the bolt and the bushing bracket comes off? I plan on...

Just thought I’d post this info in case anyone needs it too. I recently decided to change the pcv grommet on my 2000 since I’m redoing the entire vacuum system. Below is the part that I ordered through advance auto. I imagine it’s the same for all OHV Explorers, or at the least 98-00...

Is anyone on here running one of these...

I’ve read threads on this site about the tps and it seems that 19.6% is the normal position for the TPS at idle. Mine has recently started dropping to 19.2% at times and I’m getting erratic rpms lately, like a 30-50 rpm change every second. The truck runs really smooth and the rpms stay steady...

I installed a 400ml catch can on my 4.0 OHV, since I was tired of finding oil on my IAC every few thousand miles. Is anyone else running one? I can post a list of parts required including hose lengths if anyone is interested. It’s still too early to tell how much oil it’ll catch, but I’m...

I replaced my coolant sensors almost a year ago and I’m worried I have them backwards. I’m using the dy-1144 sensor to control the gauge on the drivers side one wire connector, and the SW5174 fan switch for the computer sensor on the passenger side two wire connector. Any experts here that can...

So, I have been upgrading and restoring my 1997 Explorer XLT 4.0 OHV since I purchased it for under a Grand with 129,000 miles, almost a year ago this month. I haven't had any major issues with the vehicle at all and have put quite a few miles on (160,390) it from driving it to Florida and back...

Back in 2015 my heater hose broke and caused my vehicle to overheat, and I’ve replaced every gasket down the lower intake since then, due to leaks. I started getting a misfire(p0304) a few months ago and was losing coolant. I added some k seal and it went away. I drained the radiator to get rid...

Alright. I've got a 93 Explorer Sport 4x4. My clutch started slipping. It got pretty bad pretty quickly, despite having the clutch replaced at the end of last year. I have concluded that the rear main seal probably failed and leaked oil onto my clutch. Either that, or the flywheel failed. Either...

Anyone here familiar with “normal” voltages for O2 sensors? Two of my sensors appear to be functioning correctly and are on opposite voltages. I’ve read before that it should be that way. However, the third sensor on bank 2/3 stays steady around .790 volts. Any idea if that’s bad? I appreciate...

Hey All, So I've got a 1998 Explorer Sport 5 speed manual 106k miles. It's got an X in the vin so I believe it's the OHV v6. I purchased it at 104k and its ran fine since then. Recently it has started stalling out on start. It'll rev high and then drop to a stall. If I wait a few seconds and...

Since getting my scan tool, I’ve noticed that my rpm’s decrease and increase slightly in park, and in drive with the brake on. Does this happen to anyone else? It’s not a huge change, but they do move up and down by about 10 rpms every second. This was over the course of a minute:

Hey everyone. So it’s been a long time since I last replaced my tensioner and I really can’t remember what kind the ohv uses. I see Gates “round locator pin” and “v locator tab” on amazon, and both are listed as fitting my truck. I think I replaced it with the v tensioner last time but I’m not...

ive always loved the explorer sport, not so much the 4door model (dont want to deal with all that extra weight + fuel usage lol) i used to have a 2001 explorer sport SOHC, automatic RWD and it had 3.73 final that i swapped to 4.10 with a locker, had some all terrain tires on it and put a bit of...

Hey!:) I joined this forum back in 2013, when i got the truck from my from my uncle. He gave me the truck because it refused to start. The truck had been sitting for about 2 years outside his house before i got it. I got the truck home, where it was siting for about 2 years more. On this forum...

Hello Everybody, I recently purchased a 1995 Explorer Limited with the 4.0 OHV engine. It was running smoothly with lots of power, but then suddenly during a cold start, I heard a loud pop and then it began running poorly, with a low, lumpy idle, a significant reduction in power, apparent...

I’m going to attempt to change the fuel filter on my 2000 OHV and was wondering how to depressurize the fuel line. I’ve read that unplugging the inertia switch and then cranking the engine until the fuel runs out, is the best way. I’ve also read that removing the fuel pump fuse and then cranking...

Ok so I’ve been having issues with a combination of pulling to the right, shaking at higher speeds, and a whum whum sound that has a regular rhythm. Been chasing this gremlin for a little while but am getting tired of throwing money at it (more specifically the wife is getting tired of it) and...

Hey, i got the infamous OD light flashing on me... And at first the truck was all normal. But now when i stop at a Junction to wait on a car its like the converter stops working. You can push Down the throtlle, and rev the engine. But you won't move before you change it from "drive" to "1" gear...

Hello! I have a 1998 4.0ohv 4wd. Recently I got the p1309 code and also the p0171,p074 bank 1 and 2 lean codes. I proceed to change out the Cam Position Sensor and syncro. I did them both correctly exactly by the book. Made sure to put the engine at top dead center ect. I reset the computer (...

Hi there guys really just honestly seeing if its worth it to swap the sohc engine into my 2003 explorer with the ohv engine and what would be needed for it. Just looking for some insite i do have some experience with them and if possible il do it in the mear future! Lemme know what you guys...

I know this question has been asked a lot but I need help. I bought this exploder and it has a hard start situation most of the time and check engine light with the infamous lean bank 1 and 2. The hard starting is random, sometimes it will start right up after sitting overnight. Temperature...

Hello fellow X owners. After some research and a few mind changing finds, I have come to ask a for the knowledge of the elders. My factory clutch driven fan is cracked between blades like almost all of our plastic fans are. My clutch is fine so I can reuse that. But I was looking for non plastic...

So I've know that I had a few minor leaks since I got my Explorer last year. I just recently replaced my valve cover gaskets and cleaned up that minor oil leak. Now I have a coolant leak that seems to be getting worse. I had thought it was this hose here This is on the bottom driver side of the...

Debating on the idea of converting my RWD Explorer Sport into a 4x4. Has anyone attempted this and any idea on what parts might be needed? I do have a Manual Transmission and wondering if that would affect anything. Any ideas are welcome and would be greatly appreciated!

Hello everyone! I just did a head job and with that added Pacesetter headers to my OHV engine. They dont seem to line up perfectly with the y pipe. Has anyone had this experience before? Do I just need to get better bolt and torque them down as hard as i can? Also can anyone confirm that there...

Can anyone verify for me that a Gen 1 aluminum intake plenum will fit my 98 OHV? I've heard that the smooth plastic from the Gen 2 may flow better, but I'd really like to convert it to the metal intake both for quality/"Metal! H*ll Yeah!". I'd likely paint it and maybe some light porting. Any of...
