still nothing new. getting very frustrated with this again. there is a miss that james cant track down. he is thinking i have a back coil. i have spares so i am going to try swapping one or both tomorrow. i wanted this thing to be done for or around july 1 but i can see it not happening. the coil swap is a bust, going to check the wires as well. after that, might have to switch to a ls coil set up. its funny when someone tells you thats the easiest way to do it, but they arent footing the bill. especially when you know others have had theirs running with factory coils.
once again i think going to this holley garbage was the worst idea i have had to date.

Hopefully when the bugs are worked out, you'll appreciate the improvements.

 

[410Fortune]

I agree! A dead miss sucks! We are frustrated with you, hoping it can be remedied and then things will smooth out

so i went there today to see if i can do anything. we started off by taking a infrared head gun to the header tubes. found 6 and 8 running way cooler then the others. pulled the plug out of number six. i wish i took a picture of the plug. one haft was black, the other haft was clean, and i mean dead center of the electrode. tested the plug wire, ohms seemed to be ok. measured it up against a spare i had, and it was almost dead on. tried changing coil packs (didnt think it would make a difference but worth a try) didnt change anything. reversed 1 and 6 at the coil. no change. new plug, no change. had the truck running and unhooked the injector from the harness, no change. ok, lucky for me a friend has a noid light. put that on the injector harness, lights up.
the only other thing we couldnt check was the injectors.
so whats going to happen is he is going to put evil in his trailer, and bring it back here tonight for me. what im going to do is this. when i bought dono's truck and all his parts, he also had a set of 60 siemens deka injectors. i am going to send those out and have them cleaned and tested, then swap them for the FAST 60's that are in the truck now.
i am also going to drain the tank and put new gas in. wont hurt. as well as i am going to pull the passengers header off and try to fix it (have a crack in it someplace and the tick is driving me nuts).
im also going to pull the intake and blower off to make sure i didnt block any injectors off trying to seal the upper and lower together. i am also going to try to seal it up a different way as well.
i am going to try to have all this done for next weekend. tall order, i know but i have friday booked off as well as we get monday off as well so we will see how things go.

Might want to check compression on those 2 cylinders compared to 2 others, ..

 

[410Fortune]

You can do it! yes before you pull it apart check compression, is a valve not opening or closing?

 

[vroomzoomboom]

was able to work on it, but not until later on (have a friend that had surgery a while back and cant lift anything heavy. guess who his mule is). blower and intakes are ready to pop off, then i lost motivation, and brain function. which leads me to ask, anyone know if you can do a compression test with the intake and trottlebody off? asking for a friend.

 

[Turdle]

Yes, that will work fine.

 

[allmyEXes]

If you compression test shows that a cylinder or two are low, pull your valve covers and watch the rocker arms and push rods to make sure that you are getting full travel. Could some camshaft lobes got damaged incidentally?

it has backfired hard enough the entire town heard it. the thought of a bent pushrod has crossed my mind at somepoint.

 

[410Fortune]

Odd you say this.
My buddy rich that I do these trucks with had shoulder surgery 4 weeks ago…
I’ve been his mule! Mowing the grass weed whacking (10 acres) taking trash driving places… he would do it for me!
You are a good friend. Good things happen to good people. Let this sucker run on all 8 and smoothly!

 

[ahodges]

I'm still watching a rooting for you Tim. I need you to get back to AFN next year so I have more motivation to go as well. You are doing all the things I know to check. Last 2 things are compression and fuel.

trust me. every end of may, and begging of june suck for me on facebook with all the afn posts lol. not sure if i will ever get back there with the price of fuel, and the exchange rate on our so called dollar. i think the last time i went it cost around 800-900 in fuel and that was with the 302 and m90 on it

 

[vroomzoomboom]

blower and intake are off. it truly amazes me how heavy that thing is.

years back when i was helping dono with his truck, we were going to put tmh's on his truck. i remember the passengers side looked and was a major pita to do. fast forward to today, i had a idea im going to try.

i remember the heater box was one of many things in the way with hes headers. at the moment, there was no freon in my a/c plus i had to drain the coolant as well, so why not pull the heater box off to pull the header off (i have a crack in it someplace that that i need to find and weld), this looks a lot easier then poking threw a wheel well, and lifting the motor up. times gonna tell, and that project will be tomorrows mental breakdown err job.

Looks easy to get to now! LOL. Great idea that might help working on this to be a little easier.
Why do you think the headers keep cracking?

this is the first time ive had a header crack....i think. i would say its because when the exhaust was built, they might have made it too tight or didnt brace it (?) well enough and over the years of heat cycles it has shrunk enough to make it so it is now putting pressure on the header pipe.

speaking of headers, i couldnt get it off today. a hour or so after getting home it rained small farm animals up here! hail, lighting, massive thunder! even had a tornado watch happening, so i had to stick to the grunt work of cleaning gaskets off.

prof she wasnt happy. also ran into a small problem. what i didnt know up until tonight was dons old injectors are ev6. the holley harness i have are ev1. i have 2 choices to make. somehow by a miracle find adaptors or (and if anyone knows for sure i can do this) redo the harness using the pins from it and put them into a ev6 connector.

 

[4pointslow]

If I remember correctly, the pins are different. I cut my old ev1 connectors off and soldered on the new ev6's.
They make adaptors, but I'm sure they will cause problems down the road when they come loose or something to that effect.
I would not use them unless your injector connectors are easy to get to when everything is all back together if that makes sense.

 

[4pointslow]

 

[vroomzoomboom]

i had a few places tell me to spice the connector in. i have to tell them its a holley harness that i DO NOT want to butcher up.
yes, those are the adaptors that i am after.

so lets go after the good news. i made a few posts on some facebook pages i am on and had a few responses. anyone who responded however is a min of 4 hours away....pass. called around this morning and found a speed shop that had them. even more lucky, dono works near the store, and picked them up for me, i then had a friend who was coming home picked them up from don's house and brought them home (dono is about 20 mins from me but i wanted to get going on evil).

my idea about pulling the heater box turned out to be a win! i was able to get at all of the bolts with no problems. even the real hard ones were no problem. was also able to pull the header out effortlessly.

this is when reality didnt slap but backhanded me across the face....

i tried to find a crack in the flange. couldnt see any soot. grabbed a flashlight and looked everything over very close, still couldnt see anything. i have a block off plate made for storing motors with no manifolds so i bolted it on with a gasket on one end, and figured i would just try filling the header with water just to try.....found the leak...

thats inside the collector. see the top? that has rusted or something away allowing a leak. more then likely these are garbage now.....joy. i have one of dons old headers here, but they fit like garbage. i will have to take them to work to see if i can heat up a pipe and bend it some (not hammer it because that still wont clear).

back to the connectors for the injectors. after finding the header leak i figured i would put the injectors in the intake with the rails and ev1 harness. well.....when i went to plug the adaptors in, they sold me the wrong ones. they sold me a ev6 injector to a ev1 harness. yea, i have that already. looks like i go for a drive tomorrow to return parts and see if i can get the correct crap i need.


evil - 2
tim - 0

 

[410Fortune]

So the leak is where all 4 primaries come together? The tmh is supposed to have a pyramid there to boost velocity
Looks like yours has broken off! What the heck!

I would think that area could be welded back up? It doesn’t look like rust?

All of this is to replace injectors and fix the exhaust
Leak. Did you do a compression check?
