Hi everyone,
A bit of background....I bought a CLS55 a year ago and unfortunately the head gasket went.
I didn’t keep too much by way of documentation other than a few pictures and the memory of it being a right pain in the a*se to fix!
Before I fire up the engine I just want to do a compression test. I’ve got the tool and am ready to go.....but I’m not sure how to go about doing it.
The car has basically sat in the driveway while I’ve been fixing it for 4 months on and off.
I’ve read that in order to do a compression test it’s best to crank the engine after disabling the fuel pump and also ensure no sparks are being produced via the spark plugs.
How do I disable the fuel pump and cut the sparks being generated?
P.S. I don’t have a Xentry system to do that and am looking for a way without it.
Does anyone have any suggestions?
