Cracked Piston? Cyclinder Problems?

[mr.33]

well a while ago when my car was running weirdly i took it to a mecahnic and got told it had a cracked piston because of the sound it was making kinda like a stuttering sound.. replaced the engime

Now my car may seem to be making that same sound but im not 100% sure is there a way to test or check if tehres anything wrong with the pistons/cyclinders?

Go to repco -or of the sorts- and get urself a cylinder pressure tester.

You stick it instead of a spark plug crank the engine over and it records the highest pressure. Compaire accross all 6 cyl. Compaire this to factory specs.. and see if its possible.

not too hard mate, pull your spark plugs out, unplug CAS (loom attached to the thing on the front cover of the engine) and injectors (injectors are the grey plugs on the intake side on the front of the motor) make sure the compression tester is de-compressed, screw into the spark plug hole as much as you can by hand (dont over-kill).

sit in the drivers seat, put your foot to the floor, wait for 5 rotations of the motor and stop.

then go check compression. write it down and note which cylinder

then repeat.

report back.
