Yeah, that happened about 2 years ago. I thought I had slung a rod or something. This is the outcome. I think it had something to do with that hidious rear bumper that was on the car. Needless to say, it was sold. LOL

I don't see why that would hurt anything, but I'm no expert so don't hold me to that. It's just for crankcase ventilation. The oil problem should be solved first though. I have a 347 stroker and I don't get oil in the PCV. It sounds like one of the problems that mjr46 mentioned.

The main reason the plug is there is to fill that hole (obvious, lol) but the hole is there becuase Ford had to drill the block from the rear cam bearing to feed the oil gallies for the lifters. Then the hole was plugged. It is also needed when cleaning the block to be able to clean these short gallies. I have a Screw in plug in my DSS block.

Crankcase pressure will be bad enough to blow oil out of the breather. If it's bad enough it will start blowing oil out around the seals

so by puting the fliter on the valve cover and adding extra ventilation will help this, or is is something else that has to be done

perform a wet and dry compression test and a leak down test, these tests will tell you the internal integrity of the motors ability to seal

If it has true blowby only a rering will help it. Like mj says do a wet dry test on it.
