Hello fellow dsmers,
I am stumped and came here for help. Sorry if I posted this in the wrong spot. Anyway, I have a 91 talon it has a rewired 255, precision 1200 injectors, fuel lab afpr, competition pressure plate, six puck clutch, fidanza flywheel, and jackal for tuning. So the problem I am having is at idle and driving I can hear a metalic sound almost sounds like it is coming from the front of the engine. I have checked the turbo and spun it with the car off and cannot reproduce the noise. Also when driving the car it will do fine if I am in vacuum but once it hits boost it seems like 2 cylinders cut out. When I open the hood I see oil sitting on the intake manifold right by the #4 injector. I'm thinking I may have blow by and it is pushing oil out the pcv? I have not done a compression test yet but it is on my list of things to do. I have read about lifters sticking but I don't think that is it because I do not hear any lifter tick. It all started after I was doing a pull in 3rd at 23 psi when it broke the exhaust manifold and started running poorly. I have been wracking my brain trying to think of what it could be but I am lost. If it was bad rings then wouldn't the car be burning oil? It is not burning any oil. Another thing I am going to check is the timing to make sure it didn't jump timing. I have thought about taking the engine back out and sending it to the machine shop to get the bottom end built.
Any and all help is appreciated.
