Alright guys, we've been working on this for a while now and I'm starting to wonder just what the hell. A few weeks ago I checked the compression getting readings like 36, 42, 46, etc. so we tore the engine down, honed the cylinders checked the valves, rings, gaskets and everthing else, put it all back together and we're still getting the same readings, given it does have a little more power than it did before, as far as compression goes, its the same. Now this engine is intresting because during the rebuild we found out that it was originally a 72 1.7L. However, the bore is 94mm? could this have an effect on compression? and if so are my readings close to what they should be? Also is there a special technique to doing a compression check on the 914 that differs from a standard engine?
Thanks |

Somethings not right with your testing. I would suspect a bad compression gauge, with compression under 50 pounds on all your cylinders, your engine wouldn't even start.
