exhaust from oil fill cap


Recommended Posts

After adjusting the valves on my 72tii resto, I started her up and opened the oil fill cap to take a look. I am getting a lot of exhaust from the oil fill hole. The car sat for about 10 years before I got it, and the engine was in unknown, non-running condition when I bought it. Right now she idles kinda bumpy, but revs nice. How much blow-by should I be worried about?

The blow-by coming from the oil filler is normal up to a point. Chocolate malt gooo on the filler cap is a clue that you have too much blow-by.

Sitting so long the ring might not be lose and are gummed up and stuck. I put in Marvel Mystery oil in my gas! Yes gas. A pint in a tank full 3 or four times will lubricate the upper cylinder and hopefully loosen up your rings.

Have fun and in your case do an "Italian tune up" which is very fun.
