blowby issue when under load - smokey!
Hi all - have a a4.. just replaced the head gasket (it blew) - was an old asbestos one.. head wasnt warped.. just did a nice block sand and its holding well.
Now when under throttle, after a while there is quite a bit of smoke coming from the filler cap making it quite unpleasant below. The card was rebuilt, the vent hose is in good shape.. seems either the valve guides are real bad (oil being pulled in when hot) and a certain amount of blowby- Usually blowby is mostly air, but the smoke seems to indicate oil. Fyi new oil 5 hours ago and still very clean. Any ideas? iirc weight was a 10w30- Is there an option to put a cap on with a hose to the air intake or maybe block it off and force the vapors thru the carb via the intake? |
