Anyone got a DIY method for compression testing?
Had a search - no luck except for some figures here....
https://www.crossfireforum.org/forum...t-results.html
Was wondering if there is a good test where I can run through the cylinders one by one.
AFAIK stock cam - stock car
Obviously looking for ring and valve seat wear - 80k Miles - but obvious sludge problem in the process of cleaning up - looking at options.
If Compression down - another nail in the coffin towards a rebuild - if Compression - good - maybe simple cleanup.
Manual says....
"......SLK32 - Compression should not be less than 689 kPa (100 psi) and not vary more than 25 percent from cylinder to cylinder."
But I'd like to compare against factory spec. whatever that is - still searching. Maybe MB would relinquish the records...;>)

coil packs disconnected and pull the fuel pump fuse. use a compression tester with a flaxible hose and a friend to turn the engine over. same as any other engine
Yes. While cranking, let it hit for 3 or 4 "puffs"
I forgot to open the throttle body when I did that test. It still worked but took longer to pump up. Pull the fuse to the fuel pump. Take off the coil packs and plug wires and just do one cylinder at a time. I'm curious to see where your pressure is at compared to mine.
