help me figure out what i did

[grendel]

ok i put a 9psi intercooled procharger kit on my 02 saleen,it has an a/f of 11.7-11.9 all the way through. had it for about a week and when i shifted into second one time it just died, i started it and i had to keep giving it gas or it would die, it idled like ****. there was no other kind of odd noises like knocking or anything like that. when running there is smoke coming up fro mthe passenger side head, and i only have a compression of 6 in one cylinder and 7 in another. think it could just be a head gasket giving out? if so what kind do yall recomend? i have been hearing to go with ford racing. what yall think?

Could you be a little more specific on the smoke? Is it from around the manifold/header area? Are you lossing any fluids? (ie coolant)

 

[grendel]

it was whit smoke, couldnt tell exactly where it was coming from, but it looked like the header area. my coolant was a little low, and i had some oil on my plugs

If it's a head gasket, the oil will look "milky" (indicating there is coolant in your oil). You might also see white smoke from your exhaust. Let me get this straight: You did a compression test and one cylinder showed 7psi? Or am I being misled? Because 7psi is WAY too low.

 

[grendel]

yes, 7psi in one cylinder and 6 in another, the oil was black on the sparkplug

Sorry to say but if you did that compression test correctly, your motor is gone. You don't hear any knocking huh?

 

[grendel]

nope, no knocking, thats what is weird

 

[Bmfhp]

Yeah I agree I would grab everything that will give you luck when you tear down the motor. Even with a blown gasket there should be more compression than that. Was the car running hot when the problem occurred?

 

[Bmfhp]

Not positive on this as I am learning about the 4.6L 9old school 5.0 guy) but did you reset the timing when you put the SC on? I noticed the steeda timing adjusters?

 

[grendel]

no, it let it warm up, left the parking lot, shifted into 2nd fairly spirited and there she went

 

[the98stang]

nope, no knocking, thats what is weird

Could be cracked rings/blow-by. Is it burning lots of oil?

 

[grendel]

oh, i have 2 cars the gt and the saleen, just got the saleen about 3 months ago, havent updated the sig yet. i got it tuned at strictly performance

havent ran it since, it has been siting since i have another car

 

[Bmfhp]

Have you check the fluids to see if they have combined to make the milkshake? And there is always the bad tank of gas possibility as the answer to a sudden gasket failure.

 

[grendel]

didnt see anything in my coolant but i didnt check the oil

 

[Bmfhp]

The 2 low compesion cylinders, are they ajacent to each other?

 

[grendel]

yes they are the middle 2, sry i dont know what cylinder #'s they are

 

[Bmfhp]

The more you describe the more it sounds like a blown gasket. I just am not sure how vulnerable the heads are to warping on the 4.6's. Hope this helps. I'm sure someone with more experience with the 4.6's will tell you for sure.

 

[grendel]

thanks for the help, guess i wont know for sure until i tear her down
