Default Re: Yikes!!! 305E V6 knocking like crazy!

Well gents,
Did a compression test and all cylinders are within 105-115 pounds so everything seems ok there. The engine keeps dropping cylinders once in awhile and I'm sure its from the blown head gasket or if both are blown and I don't know it. lol The one leaking currently is getting worse so I haven't been running the engine. Will be getting new head gaskets from summit racing as well as some intake gaskets and a carb kit(not necessarily from them lol). Then I might even take the heads to my machinist and have him look them over to make sure everything is ok and she should be up and running like new. I may even pull the engine to clean it up and repaint it and throw a new clutch in since this one is crap.
