Leaked M0d Auto Spreader

Thanks guysThese VC are tin, brand new, and came with the engine and I agree most likely Chinese.They came with spreaders about 1.25' long. The permadry gaskets had 2.75' long spreaders and those longer ones are what's on there now.Both sets of corks were rtved to the VC, the 'Felpro Permadry' gaskets say ' do not use any sealer'There may be a casting flaw back there, its brand new with no history so who knows.Like I said this is the first one I've ever had trouble with.The intake manifold isn't leaking, there is no oil any higher than the rear outside corner of the heads and coming directly from there. Oil out of the intake would take a path around the backside of the head and down the block. It's brand new so there is no mistake there.The crankcase is vented properly and that system is working as it should.

Hang tight a minute Newt, your problems sounds to me like you have too much crankcase pressure and it's forcing the oil out the weakest spot on the cover. My question to you, do you have a PVC valve on this engine?I put together a fresh 350 for my 41 and promptly noticed oil coming out the dip stick tube and valve covers. Pulled the cap off the valve cover and the crankcase pressure was too much, (remember fresh rings, not seated yet), short story, long version, I didn't have a PCV hose hooked up. Promptly installed the correct PCV valve and hose, seated the rings, and no more oil slobbering out the covers and dip stick tube.

PLUS another vent tube out of the other VC right into air cleaner housing. There is no oil flying out of that tube nor excessive pressure- or out the dip stick. Just leaking at the lowest part of the heads were its gathering to drain back to the pan.Maybe there's too much oil getting to the top end? Idkperhaps its not draining back fast enough???The non verified dash guage claims 55 psi at idle. Old motor had 25 psi so the gauge works relatively. If, it's leaky valve covers this is a full proof way to stop leaks.

I've used this method a long time with great success.1. Gasket seal the cork gasket to the valve cover.2. Run a bead of RTV high temperature silicone around the cork gasket, set aside and let the silicone dry tell you can touch it without any coming off on your fingers.3.

Clean heads with lacquer thinner.4. Place valve cover on heads and tighten the bolts slowly moving in a figure eight pattern tell snug, don't over tighten.There will be no leaking in this method but they will be hard to remove.CRUISER.

No doubt tweeking the corners may help but you can get a set of corvair spreaders (we used to call them hold down) cheap.I am actually thinking of casting some perimeter hold downs for using with stamped covers.

My old Harley pan head had a cast holdown that went all the wat around the outside of the pan, they never leaked and I had several bolt holes stripped out on my first set of heads.Oh one other thing getting back to the chevy rocker covers, I buy the cheap summit rubber gaskets, that have a steel shim in them and work real well. They are probably either felpro rubber gaskets in a different box or off shore copies. The only problem I have ever had with them is that they get hard after 3 or 4 years and need to be replaced.

I've had great luck using aluminum valve covers with cork gaskets and GM Assembly Adhesive. I make sure when glueing the gasket to the valve cover that everythingfits properly, tweaking as necessary. After the adhesive sets up I fill the crack on the inside with some more adhesive, smoothing it with my finger as I go. This keepsthe oil from sitting in the crack looking for a way out. Pretty much bulletproof.When I'm ready to put on the valve cover (with gasket attached) I use a single coatof Permatex Aviation Sealant #80019 on the cork gasket, let it set up for a few minutes and bolt it on.I have no leaks and the valve cover is removable without tearing the cork.

Each time I remove the valve covers I put another coat of the permatex on the cork to reinstall. To remove them the first couple of times all I had to do was put a small block of wood under one corner of the cover and tap it a couple of times with a hammer.and the cover popped right off with the gasket intact.

But, the last time I did it I had to put the car on a lift and use a long piece of oak flooring from underneath along with a bigger hammer to accomplish the same task. But, the cork gasket was still intact.I'm sure my method will work with steel covers and spreaders.Merry Christmas!
