how do i check compression with the motor out of the car

 

bolt the tranny on
bolt the starter on

use a battery and put power on the starter while checking compressions numbers

not really accurate, but it gives a good idea

heres the thing i bought an 87 TII last summer that was hit hard in the center nose so i gutted the car down to the bare shell and crushed it now i wanna sell the motor and have a 4 or 5 people asking me about it but everyone wants to know compression so somehow i gotta test this bitch it has no tranny its a complete motor from intercooler to oil pan with wiring harness and ecu i havent heard it run and i dont wanna **** someone so id rather know and let whoever buys it know the deal with it it's too bad about the rest of the car 87 TII 56k orig mi doctor owned the kid i bought it from was the second owner and had it for 7 days and killed it oh well i guess it just makes the other TII's worth more so any input with this compression test thing would be great. thanks guys

will you quit bumping, wait 24 hours! jeez..


alright, without a tranny, you are fucked, you cannot give an accurate compression test. There is no other answer that we can give you, there is no other trick, that is it, there is no reason to ask for more help.
If you can't get a tranny on it, you have NO choice but to lower the price on the motor and sell it 'as is'. Cut and dried, that is that.

 

ok finally something
