My '76 2.0L is putting out a little smoke on hard acceleration. Is there a way to tell if the oil is leaking past valves vs. piston rings ? The old trick I always heard was to test compression, put a little oil in the spark plug hole, and retest. But that won't work on a horizontal cylinder. My hunch is that it's the valves, but only because its easier for someone (PO, not me !!!) to screw them up by not doing regular valve adjustments. My records are a little patchy, but I think the engine was rebuilt less than 50k mi. ago. Any consensus on what tends to go sooner ? Thx |

Never recommend a top end only rebuild...
The engine ages evenly, if the top end is worn, so is the bottom end.. Strip it down and do it rigt, or not at all.... Top end rebuilds tighten up the top end and create more of a challenge for the bottom end, new found top end power will show you a weakness in the bottom end very quickly! Don't learn that the way I did. |
