Hey everyone the car has new heads, cam, upper and lower intake and all other common bolt ons. The car only starts when I hold the pedal down and there is alot of oil in the intake and on all the plugs. Did a compression test and got #1=165, #2=170, #3=155, #4=165, #5=165, #6=155, #7=155, #8=155. I have an blaster coil and ingnition box. The car will smoke bad when i get on the throttle and it lacks power . It idles terrible also once it starts. I have replaced all sensors(TPS, IAC etc...). Not sure if the piston oil rings are done and compression rings are still good or what. Any help would be appreciated. Thanks in advance
No, I will try new plugs today. Also after looking around on this site, I think my PCV line is to big and I have it all hooked up in the wrong order which may be pulling oil in. I'm thinking the PCV is the culprit because otherwise all 8 of my oil control rings failed at once. I am going to hook the lines up right and get new plugs and see what happens. Oh, will the car start if I put the cam in wrong????? It starts and idles fine but its hard to start it, so I was thinking the excess oil+fuel was throwing off the AF ratio bad.
Ok, so I got new plugs and ran the vacuum lines the way they were originally(Found a good diagram) and the car started right away with no issues. Idled for a while then shut it down. Went to re-start and it just cranked, pulled my top line on the upper intake and it poured a bunch of oil out of it. What would cause the excessive crankcase pressure that's causing oil to be pushed in the intake? Car has no cats, but the mufflers are original equipment. Could they be clogged causing excess back pressure? I appreciate you all giving me ideas, Thanks.
I guess that is possible. The heads were bought new less than a year ago from World Products. Very very low miles on them. They are the windsor jr heads. Oh my vacuum guage is only going to like 10 when the car is idling???????
Sounds like there's either something wrong with your PCV line, or the vacuum line from the passenger side valve cover oil filler neck to the intake pipe is blocked.
The compression numbers are good so there's nothing wrong with the piston rings. I don't think the valve guides in new heads will be worn either.
Check the crankcase ventilation system. I'm sure that's where you'll find the problem.
Ok, cleaned out the wire mesh screen under grommet for PCV, installed an air oil separator and no more smoking and so far no oil in the intake. The separator seems to still be empty also so maybe the screen was clogged causing excess crankcase pressure.
