Noticed oil in breather and around top of carb. Only thing possible is valve breather leak. But im not understanding how oil is making it back up? Any ideas? Seems serious, such as internal engine. Also, pcv is blown, springs and other pieces from inside fell into cover underneath on top of the valve cover.

 

I had the same problem, I did a compression test, all cyl. were low, I am in the the process of rebuilding the motor, oil was blowing by the rings.

 

dam, i didn't wanna say it and gink myself but i figured as much. Well good luck on the build.

 

could also be a clogged pcv valve, check and replace.

 

Go to the dealer and buy a new pcv valve and grommet. Then buy a new oil seperator gasket. If your old pcv fell into the valve cover, you can just unbolt the oil seperator from inside the cover if you have an early 22r or 20r. Then replace the gasket.

 

mine did the same thing, but i had to rebuild because the motor was shot very low comp and burning oil

 

X2 above. Check your PCV and hoses. Do a compression check.

 

Compression check is recommended, but don't competely rely on it. Had the same prob with mine. Had high compression(180psi all cylinders)....but alot of blowby, and had a BIIIGGG cloud of smoke come out the exhaust on the expressway one day. Tried a few things, but it was so bad it blew the rear main seal. Had to rebuild.

One thing you might try is remove the pcv from the top of the valve cover, and rev the engine up to 3000-3500 rpm (operating range), when I did that with mine, oil was spitting out, and the amount of gases coming out was enough to form a cloud under the open hood. You will always get blowby and pressure from the pcv hole, but that was way excessive. Turned out I had 2 cracked pistons, all broken rings, and my cam was shot, sendign metal shards into the piston and crank bearings. NICE. Made my day. Did complete rebuild, problem solved and still sitting at 180psi compression.
A leak down test is far more accurate.
You definately want to remove the valve cover and retrieve the pcv parts that fell in.

 

^ there is a baffle there that keeps them from falling down into the cam/valve train. Just pick any parts that fall in out with needle-nose pliers.
