Hey yall,

It's been awhile since I've been on here but I gots a question. So I've ripped off the emissions(air pump) and stuff, got the weber, the offy, and the pacesetter, and I have a breather on top of the valve cover and the little side one plugged off. It still makes an oily mess. I've played around with feeding a line into the top of the carb but that makes a mess, I retrofitted a pcv onto part of the line and brought part of the intake manifold into it but it got clogged and failed. So is there a good way to do this or is the breather the best way to go right now. Thanks in advance guys!

Sounds like you deleted your PCV system, find a shop manual and hook it back up. 1 breather in the valve cover lets air in, one hose going to the PCV valve which on mine connects to the intake manifold lets combustible mist out and back into the intake to be burned. Even if you delete your smog equipment, there's no reason to delete PCV.

sounds like more than what a PCV is going to do for your engine.

if you "attempted" to add a PCV and it clogged it sounds like a blow by issue.

no amount of breather or PCV is going to cure dead rings, except crankcase evac.

Well at least you read his post, I guess that's what I get for trying to be helpful early in the morning.

Yeah, if you put on a PCV and it clogged then sounds like you are getting tons of blowby.

Do a compression check. Low compression can give you the blow-by issues. You might be able to get by for a while with a (catch can) I think it's called. I have the emmissions junk, (air pump and all hoses and lines pulled/plugged) and haven't had the issues you're having.

Well, if the dry compression test comes out bad, try a wet compression test (a few squirts of oil down the spark plug holes before the test) to make sure that it is actually your rings that're bad, not just some other problem...

Hey guys,

thanks for the info I really appreciate it. Between work and school I've had almost no time to work on any of this. I've never done a compression test before and I'm not sure how to do it. I've read up on it but I'm not sure what to do with the distributor. If you take all the spark plugs out and disconnect the line from the coil to the dizzy wouldn't that mean it doesn't crank or am I missing something. Thanks again guys.

To do a comression test, only take out one spark plug at a time (Then you won't have to figure out the firing order). Then, so that the engine doesn't start, pull the coil wire off the distributor and ground it (put it close enough to something metal for it to spark to that rather than the spark plugs). Then, you're looking for about 120 psi. (LUVs have 8:1 compression, atmospheric pressure @ sea level is 14.7 psi, so 8X14.7= about 120.

I think I might've figured something out but I'm not sure. If I just have a breather for the top of the valve cover and route a line from the side of the valve cover to the intake manifold underneath the carbureator, wouldn't that be a PCV valve sytem? Fresh air can come in and bad air flows out to the intake manifold. Right? Let me know, thanks guys.

thanks on the compression test I'm gonna buy a gauge and try it out.
