I am rebuilding my 2.0 engine
This evening I installed #4 cylinder & piston (with new rings). I then tightened the cylinder down onto the case to measure the deck height. The deck height came to 0.2mm which is 0.008". as I understand it the deck height should be about 1mm (0.04"). I have installed new crank bearings, the piston and cylinder are original, the shim under the cylinder is the same thickness as the original shim. The deck height should be the same as before the rebuild shouldn't it? Anyhow the deck height seem very small. Advice appreciated |

This happed to me once. One deck height was off on one cylinder. I found the rod was refinished incorrectly. I took the case apart and removed the offending rod. I then installed the piston pin into that rod and another rod and could see the big end was not lining up. I have a drawer full of rods so it was easy to find one to compare.
Your .040 is the correct measurement. The stock rods can stretch a little. When we build a race engine with CNC rods we use a tighter clearence. Oh you can remove the rod without splitting the case. AL |
