...valves...? Hello my corvette keep leaking oil.... I replace the intake manifold gasket fixed one leak and now when I hit 5 grand dipstick shoots oil... I am sure the cat is the original car has 140,000 miles 1989 corvette l98 engine doesnt burn noticeable oil amounts... I have one pcv valve running from the intake to valve cover with strong suction, also I have another PCV valve in the breather location. It is where the breather should be... My question is is the breather suppose to be a PCV or a rubber boot? because it is suppose to let air flow in correct? The pcv valve will not let air suck in. The dummy before me put it on if it is not suppose to be there...My understanding is there is suppose to be one PCV and one breather tube to the airbox with no pcv valve. Am I correct? I really hope so it makes sense to me that since air is not flowing through the breather it is causing extreme crankase pressure also when I fixed the intake I had to burp the system for coolant the engine hit 280 degrees for about 38 seconds and then I cut it off. It did it because it was low on coolant obviously but if it cause major damage would I know thank you to anyone that can help me I certainly hope that the reason this is shooting oil out of the dipstick is because there is too pcv valves with no circular air flow. and also the cat is clogged a lil. and the timing is off I am assuming it wants to run great sometimes and then others it idles funky and stalls sometimes ever since I change the gasket can I just turn the distrib housing to set timing?
