Post Need some help here with a 36 Prodrive
I just got this motor a couple months ago. Don't know much about the prodrive a. It has ran great. Yesterday all of the sudden all the oil blew out the back of the motor. I thought I blew the crank case gasket but come to find out there's a hole in the top of the block that it was spewing from. I'm not sure what was there or goes there. The motor has a mikuni carb so I'm thinking it may of been something from the stock carb. Sorry if I'm posting in the wrong section. Here are some pics. Thanks in advance for the help.

I'd say you have bigger problems than that hole.

Might have been where they mounted the fuel pump. Moved it to cover up the crack....prolly had a bolt or plug in there just to the hole. Be interesting to see what the other side looks like....Belzona and weld metal?

That has been there since I owned it. Nothing leaks from the line. Not sure of its a casting flaw or a hairline crack.

No idea....just looked through some photos of my engine and looks like I can see the same hole....minus the other side of it.


Most liberals seem to suffer from the same mental condition....it's called stupidity!

So, 36s use a mech fuel pump like the 32s?

Talked to prodrive. That hole had a small ball bearing seated in it. The port was for testing at the factory. They advised to tap it and plug it.

In all reality the block is cracked. Sooner or later it will leak there and then shift the cylinder.

Probably. But it's doing good now. 10 years old 276 hours. Might replace the block this summer
