1275 rear seal??

[dingleberry3343]

I am rebuilding a 1974 1275 midget engine. I was not the person to tear it down and have not assembled one before.

My manual says nothig of a rear main seal, yet the gasket kit calls out a rear main seal. The seal seams to be 2 pieces of cork about 3/8 wide and 4" long.

Where do these seals go? Do they seal the oil pan to the main caps on the radius?

Is there a seal at the rear of the crank or is it just the lip on the crank that rides in the recess created by the rear main and the small cap?

HELP!

The two pieces of cork go at the curved ends of the oil pan. there is no rear seal per say in a 1275 or any A-series engine for that matter, they have a reverse scroll on the back of the crankshaft to pull the oil back in the crankcase. They do make aftermarket seal kits for 1275s, but I never had any sucess with them, in fact they work worse than the stock set up. I buy Payen bottom end gasket sets for the 1275, it has rubber pieces for the pan and they seal better than the cork one, if you need just thoses tow rubber pieces, The B Hive has them separately.

This site is a life saver. I think by the time this car hits the road I will have lost my mind.

Thankyou very much

T'is normal for them to drip a spot or two of oil when parked. When you shut it off the scroll is no longer scrolling and and when the oil drains down some can get past the seal.
