How are the sleevs fitted?(L4-134) No bottom- or top stop, as I can see? Just "squeez fitted"? What tolerance should it be on the bore? Best, Ola

Hi, Will this sleeve be okay to use with 030 pistons. Thanks.

Willys Jeep Parts Tech:
You really wouldn't want to sleeve at .030 - usually you wait until the engine is at 60 or 80.

Is this price for one set (4 cylinders) or just one cylinder?

Willys Jeep Parts Tech:
These are each.

Will this engine sleeve fit this size bore 3.1250"inches and 79.375mm. Regards Christy Wilson
