    Compression test? W124/M104

    Just done a plug change, and I have to say, the ones I pulled out don't look great. Although, I'm wondering if the oily gluey buildup on the threads is just the stuff that stops em jamming. (Antilock grease? The name of the stuff alludes me right now.) I've never done a compression test...

    Which Compression Tester Kit for OM617?

    Hi All, I've never undertaken this job and would like any advice on which kit to buy - and any tips on using it if possible! I have a couple of Petrol engines as well, so it'd be handy if they were dual purpose - or are they all if they work for diesel? Many thanks in advance. Cheers, Paul

    240d compression

    I have a 240d from 1982. 120k kms from new. It is low on power and my garage tells me the compression is low on three cylinders. Seems odd since I had a test 4000kms ago and it was ok. So, it could be, I guess, head gasket, valves or rings. First, am I right and second, what is the most likely...
