Hi All!
New to the forum and recently purchased a 64 150. I am having problems with excessive amounts of oil being blown out the top head breather. Any ideas on the cause?

You can help diagnose with a compression check (differential is best) after you double check the oil levels. You didn't say if you were burning oil or had any other indicators like fouled plugs. I'd suggest a thorough trouble shooting regime so you can get a real handle on the health of the engine. In truth there isn't too terrible much to go wrong with these so should be easily tracked down.
