Need Help Oil And Fuel Problems

[scarface1689]

I Have an 86 turbo z t1 auto car and here lately i noticed i was going threw a little oil so i checked my plugs and they are really white with orange on them which i thought was kinda strange but i got to cylinder 3 and noticed the oil was pushing its way pass the plug but all the plugs are clean looking with all having orange on them. the other thing i noticed was when i take my vac line of my fpr my car seems to idle better and be more responsive so is my fpr bad and making my car run lean. i just changed my fuel filter so i know its not that

Have you checked your FP with a gauge? How much is a little oil?

[scarface1689]

no i dont have a fp gauge but a buddy might how do i hook up fp guage and about a quart a week

Some heads are porous and leak oil around or into the plug holes. Post pics of your plugs. Do a compression and leak down test.

You should be able to see where a qt. of oil per week is going.

ya down the block onto the ground ok will take pictures of the plugs 2marrow i talked to my buddy and we are gonna be doing a compression test fuel pressure test and he is gonna tune my car

[scarface1689]

well i took did some y\tinkering my self and pulled my kick panel where the map sensor is and notice the vac line wasn't all the way one on so i pushed it and it seems to runs better but now the car is throwing a code 24 which is the tps sensor so could that be the root of my problem

the compression was 90 on all 4 cylinders is this normal

the compression was 90 on all 4 cylinders is this normal

Did you remove the piping to the TB and open the throttle all the way during the test?

[scarface1689]

no i was told take the wire of the coil and hooked the guage up to each cylinder and let it crank for a couple of seconds and every one i got 90what piping you talking about the one that runs to the airbox? Thanks for the help Cordes

EDIT, I was late on it.

Yeah piping to throttle body.

if its 90 on all its consistant, but its low.

[cordes]

With the air filter, IC piping, and closed throttle body the car will have a hard time pulling in enough air to get a good reading. Given that you have all of that hooked up, I'm fairly certain that your compression is good across all 4 cyls.

You can double check by having the throttle wide open with the TB exposed so that as much air can get ingested as possible. If you disconnect the HEP the injectors and coil won't fire.

ok oh by the way remember when i said i thought my rings were bad they are not my valve cover doesn't leak oil until you get on the car so i will be changing the valve cover gasket and my o2 sensor and my fpr soon hopefully this will cure all my problems could the o2 sensor and the fpr cause a cutout under hard accleration
