Air out of oil filler cap.

[zeeth2800]

I just undid my oil filler cap and reailized air was coming out.

I would think of low compression but the car runs super strong and doesnt lag at all.

could if be the vacume?thanks i am not very familliar with these motors and i just got the car

What do you mean "air was coming out"? Did it hiss when you opened the cap, you mean? That would be air sucking in. Please specify.

hey man sorry i wasnt more descriptive.

when i take the oil filler cap off and put my hand over it i can feel air coming up and out. like a very soft blowing.

also the car is running VERY rich and oil has mixed with the gas. when i take the oil cap off and it is running a few drops of oil "bounces" up and out of the unscrewed filler opening.

i am planning on changing the oil soon because there is so much gas it is at a rather watery consistancy.

I was planing on some castrol 15-40?any suggestions?

Rotela 5 40 or 15 40 should work. =) also dont run that car antother minute like that and get your tuning issue straight. your gonna kill that engine.

as for the air. Possible blowby?

yea man right now the car is parked...im not risking running it with such a thin velocity oil. or should i say mix

thanks

could it be anything but blow by?the last thing i want is to have to rebuild or sell the car.

thanks

It's prob blowby, but I wouldn't be too worried about it either. My brand new motor did that. If the compression is alright, get it tuned and enjoy.

i ran my motor pig rich for awhile and it never had gasoline in the oil. checked it yesterday and it smells/feels/looks like oil..sorry to hear about your that man..do you know why it is running so rich?

[MeanGreenS13]

i have blowby to the point where it smokes lightly. but my compression numbers are extremely strong and almost exactly even across the board, so im not worried one bit. The smoke is nothing but a nuisance

Aight well i will do a compression test this week and tell you guys the numbers!thanks for all your support.

it got me pretty worried because i just got the car thursday.

thanks again everyone.you guys are a much better community than 240sxforums.com
