If I don't fit any gasket at the top of the cylinders (which is what every expert suggests) will this affect the type/thickness of shim used at the bottom or is the increase in compression so marginal that standard shims can be used?
This is for a all standard 1,7 D-jet engine rebuild. /Lars |

If you choose not to use them, plan on calculating the CR and shimming accordingly (we do that with the gaskets, because you need to do it)> You'll need a way to accurately measure the combustion chamber volume and a way to measure the piston deck height.
