Hello All-

I have looked but found nothing on what the specs are for checking this on a cold engine. My 1977 300d (non-turbo) has not ran for two months. I wanted to get an assessment of my engine's health before putting money into it to fix the problem. The thing I need to know is what a suitable compression range would be when the engine is cold. I know proper testing would be a warm engine, but unfortunately I cannot do that. I also am going to adjust the valves prior to the test, but do not know the specs when cold either. I have the valve specs when the engine is warm...

Any help would be greatly appreciated.

Thanks,

Peter
