Suction Pressure On Oil Filler Cap

[1949panrider]

Hello, I would like to know if I should have suction pressure on the oil filler car as I remove it? I posted earlier that I put a new Timing belt on my 1988 2.0 MM and two days later it smokes like a freight train. I pulled the plugs today and they were really black and wet. I also checked the compression on each cylinder and they all checked good. I put a new set of plugs in and within two minutes it started the white smoke again. This has got me puzzled and I am hoping some one can help me out. I would also like to ask if anyone knows of a good mechanic on these trucks that is in or close to Winston Salem NC. Thanks

If the engine is running, yes, there would be some suction on the cap. It would also affect the idle when you remove the cap.

Passed through Winston~Salem a couple years ago, but luckily did not need a mechanice, so I can't help you there.

Thanks royster, It is going to be 40 degrees tomorrow and if I can find new valve seals for my 2.0 I am going to try and change them using the rope in the cylinder or the air pressure in the cylinder, I need my little truck to drive to and from my friends house, I am restoring a 1972 Chevy C-10.

I hope all goes well. I assume you've checked the PCV lines? It's sort of baffling that a new timing belt would prompt smoking, but these trucks can be fickle. This is a whole FORUM of fickle.

But they are wonderful when they're happy. Hope yours' gets happy soon, Panrider.

Hey royster, Is fickle the same thing as PAIN IN THE YOU NO WHAT? You know this a great sight to talk to people that has or will be going through the same things as we have and maybe we can help others. This has really bum fussell me as to why this just started after put the new timing kit in. I have thought about it alot and maybe the oil pump was not in time when someone else put a belt on it before, and when I done it I put it in time like it was should be and it gave it more oil pressure up to the value cover and the valve seals was bad before I done the timing belt kit. JUST a though, I don't know. Anyways thanks for the support and I will let you know if the seals I put in today fixes it. I hope NAPA can get them for me today!!

O I forgot to tell you that the PVC was working but I cleaned it anyways.

They make an elimination kit for them things. $40.00 or so. Rockauto.com. We even have a thread for a discount code. I think it's in the general discussion area as a sticky.
