Compression Test For engine out of car


Compliments of 328iJunkie @ http://www.r3vlimited.com/ 



See Vid:


Did this for a customers S52 i just picked up. Very easy to do. Either do what i did and use a junk auto trans bellhousing or bolt up a trans, bolt up a starter, Positive to battery Then just ground the starter or motor to the battery. Top terminal (the one that has a 10mm nut on it) to the + on the battery will fire the starter. I used a fused link with a 7.5amp fuse in it just for safety.

(Make sure theres some oil in the pan lol)
