Alright, trying to check the compression on my motor. Motor is out of the car. I have compression tester, battery jumper. I connect positive end to the positive of the starter. Am I doing something seriously wrong here? And the thing won't turn by hand.



What am I doing wrong?

I guess your doing something wrong if your jumping the starter and its not going.

You have it grounded too right?

if it doesnt spin by hand, theres something wrong with the engine

Yeah, it is grounded.



I wondered about that j9, but it turned before this time, which was a few weeks ago. Maybe I should try putting a couple ounces of oil into it. I don't want to put too much, which would be a good amount to put in?

try turning it backwards, too

tried that also. it's tough to turn, but it does, just takes alot of brute strength, something that I don't have alot of!

if its really hard to turn id be concerned maybe something fell in the engine or something is stuck in there...

yeah, it should almost spin by hand

I had the exhaust ports covered up, and the LIM was covered. unless something managed to crawl in there somehow. there really is no way of checking this out without tearing the block apart. something I don't know how to do.



****!!

ill take it off your hands for a few dollars https://www.nopistons.com/forums/pub...IR#>/smile.png.



put some oil in there and work the crank back and forth a little bit, should break it free.



i'd imagine.
