Inliners International Forums General Discussion Engines Full Flow Oil Conversion Problem

Alright Guys, I am in a heap of trouble now!

I have a newly rebuilt 235 with lots of goodies.
When they rebuilt it the machine shop did not feel that they could tap out the holes required to install a full flow oil conversion as big as
suggested in the Tech Tips section so they went one size smaller.

1000 miles into this new motor the front and rear seals are blown out of the motor and I have a nice steady stream of oil coming out between the motor and transmission.

What is my best solution after replacing the seals at this point?

Should I abandon the conversion by removing the plug to the mains and plugging the newly tapped holes for the bypass oil filter?

Should I just pull the dang motor out of the car AGAIN and tap out the bypass oil filter holes bigger myself?
Any other ideas?

Thanks,
Fabian

Dear Fabian;

It's hard to say what went wrong there. You may have 'blown out' one of those oil plugs in the rear of the oil gallery.

I would pull it out & check them. The seals are another problem.

Once you've resolved those things, plug the holes and run the oil pump to see what pressure you have.

Good luck.

It was the oil pan gasket. It blew out the front and back and a little bit of the drivers side. I think my draft tube may be plugged.

Thanks for the info.

Another question: Should I be putting gasket sealer on both sides of the gasket or just on the oil pan side? The Felpro gasket didn't come with instructions.

Walt,
Thats what I think as well. I am trying to make sure the draft tube is not plugged up.

F;

On the (early) engines you want to seal the block & main cap side ONLY.

Then you put 'hi-temp' grease on the pan side. This way you can R & R several times W/O replacing the gaskets. It holds the long pieces in place too; as they go on first.

The (later) may be different as Walt said.

Good luck.

I have a 1960 Bel Air with a 235. The overlap between the side gaskets and the end neoprene seals seem to be the challenge. The neoprene ends squeeze out the cork sides and tear them when I torque it down to spec.
