White smoke outta filler neck...

[SAYiWONT]

I have a 95 and when its running it blows white smoke outta the filler neck when cap is off. When I put cap upside down over it it doesnt rattle off. It hardly moves. Soo im hoping its not rings, also no white smoke outta exhaust. Also you guys that run oiled filters like k&n when its dirty can you really feel a difference?

Run a Donaldson or Napa filter etc....

As for the white smoke it's only blow by. If it's not too serious then dont worry about it. How many miles are on the truck? I'd have to see it to know how bad it is.

Its got quite a few miles near 300,000. I just recently got it so i wanna run a dry filter and i still have to get to changing out all fluids and doing leak down compression test.

Mine has 205k and has some blow by. Really not too much to worry about. Napa 6637 filter or equivalent will do the trick. I put a Donaldson on mine and it made a noticeable difference. Changing oil is the main thing that will keep these things running happy.

Actually i think the knuckle head that i bought it from put 10-30 in it!! If ya cant afford to maintain it dont buy it.

Blow by is there. Don't worry.
10W30 diesel oil is ok as long as it's in the correct temp range.

I wouldn't worry about that small bit of blowby.

As for the oiled filter elements - no, I don't notice any particular power loss, but just like a paper filter, the intake vacuum *will* pull silt across the filter media and into your engine when the filter media is nearly saturated with dirt/dust/silt.

Keep you air filter clean-ish.
