Compression test procedure

[travisd]

I am looking for the procedure to compression test a 4.4 liter lc3. Do I need to take the belt off the supercharger and remove all the plugs? Does the vvt need to be turned of or any procedures for that to get accurate reading. Do I just let the push button start keep trying to crank after full compression is read is there a way to stop the starter after several times turning the engine.

Last four steps out of pic are install air duct to TB, install spark plugs, install PCM, and install ignition fuses to the IP fuse block

Do you have the info for a bleed down test

 

[luxuryrules]

Yes, it’s specific to the LC3. I’ll see what I can find for a bleed down test. Is that what is sometimes also called a leak down test?

 

[travisd]

Yes sir that's it. Thanks
