Hey guys I have a 1979 chevy luv ive owned for 10 years and I absolutely love it. Besides the headers and a weber carb its completely stock..... now what I need help with is generally when I get it up and between 70-80 mph it builds up pressure and starts spitting the oil out of the dip stick and I think it is also spitting it out of the oil fill cap cause it keeps pooling oil on top of the valve cover...... I have removed the valve cover and cleaned it I also checked the breather hose that goes to the carb its clear and I also checked the vacuum hose that goes into the valve cover its got plenty of suction...... what do I do?????? Please help....

Make sure you dont have too much oil in the engine. If the oil level is correct you may have too much blow-by

With the 4 speed? You're braver than I am...

As already mentioned, maybe you've overfilled the oil. Usually the 3rd reading is accurate, there are threads here on this subject. Something about pressure in the crankcase and the shape/location of the dipstick tube...

Purchase an oil catch tank for starters, and if you haven't already - switch to a 5 speed and better geared rear end (preferably out of a newer mid to late eighties Isuzu Pup because they are stronger). G series engines won't self destruct from revving them too much - but they will blow by oil if you do it constantly.

Even my Impulse 1.9 G200z engine I'm running that was designed as a high compression engine from the Isuzu factory does it somewhat if I run it too hard in the higher rpms a lot. Which I do...a lot.

How's the PCV valve in that truck?
