Hey all,
Ok let me tell you a background of the motor so you can eliminate some problems.
-fully built KA-T
-JE pistons
-Crower Rods
-JWT Cams
-JWT ECU
-72lbs injectors
-block 0-ringed
-etc.....
ok here is the problem:
-motor has 80miles on it. just got it redone after having an issue with the valve guides. I have yet to take in boost and i am staying in vaccuum all this time. I drove it from work to my house last night and half way to my house the motor started to bogg. I barely made it my hill to my garage. when i got out, Clouds and clouds of white smoke poured out of the exhaust and when i opened the hood, i found that it was only running on three cylinders.
things i checked when the car was running:
-perfect vaccuum
-perfect fuel pressure
-perfect oil pressure (about 22psi at 1000rpm)
after i shut the car off.
-perfect color in the oil
-no oil in the water
-spark plugs (1)(2) and (4) looked great, nice brown. (3) hosed with fuel.
-did a compression test (130, 130, 115, 130)
-looked at every pistons top through the spark plug hole. all but the number 3 cylinder was fine. the number 3 cylinder was black and had a puddle of fuel(or some other liquid that i couldnt really see) on top of the piston. It also smelled like fuel from that cylinder.
-checked spark in every plug and it was good
-checked the ecu codes it threw, 132, which i think it IACV or MAP/Boro switch, cant remember. however i always get those codes
-checked MAF sensor and it was good.
tonight i am checking:
-pressure test on cooling system to see if coolant is going into the cylinder
another note: the smoke coming from the exhaust did not smell sweet like antifreeze but smelled like fuel.
not sure what to do now. I dont want to pull the head if I dont have to. I want to be sure that it is the headgasket before i do that.
thanks
jeff
