I recently purchased a set of 1.7 Liter pistons and cylinders for my 72 914 Porsche from AA performance. I noticed that the rings are installed and the pistons are in the cylinders. Is it necessary to remove the pistons to configure the ring spacing or is it already done? Can anyonre tell me how they spaced the ring gaps around the piston? In the old days compression and oil ring gap would be alternating in the 9 and 3 o'clock position.thanks

Can you really expect rings to stay oriented the way they were installed? My other flat engine (a Subaru) goes through oil like mad sometimes, then seems to hold it OK sometimes. I always thought it was the rings getting oriented with the gaps down sometimes.

My other flat engine (a Subaru) goes through oil like mad sometimes, then seems to hold it OK sometimes. I always thought it was the rings getting oriented with the gaps down sometimes. I'm not sure. With VWs we would keep the rings in the upper half of the cylinder and would not have issues with oil burning. If on occasion the ring gaps were down it seemed to use more oil. It would seem that the rings are going to stay in the orientation that they start. There is no force that would make them spin. |
