What up,

I'm interetsed in a car that has a 94 GSR motor...the car runs nice, and pulls pretty hard with no smoke! The guy says theres only 77K miles. is there any way to check besides a compression test? also was 94 a good year for GSR motors? any defects?


thanks alot

also i heard there is a stamp on the GSR tranny! where is this stamp located? and what is it suppost to say?

 

well, the 94-95's are OBD1, so thats a pro.

do a compression test and leakdown test. USDM engine? carfax the VIN#.

 

Where can i pick up a compression test??? can i get it at any local auto parts store? and what numbers should the GSR be posting?

 

there's compression testers at autoparts stores. kragen, autozone, etc... i'm not a DOHC person, but i think its 220. not sure. hopefully somebody will chime in.

 

thanks alot bro..ur a big help! hopefully the damn things arent tooo expensive

 

I've read the gsr should be around 200psi per cylinder thats what mine was at around 120k miles. Its pretty much good as long as the numbers dont go up or down 15-20+ psi per cylinder.

 

k cool...how do u use compression testers?

Woah hold up..
First of all, a compression test isn't a set number or a goal that needs to be reached.
I've used testers that ran around 240 across the boards.. while other utencils brought me near 200s ont he same motor.
If that motor is in good shape a compression tester should be reading over 200 nowadays, sure there are tests that can show 230-240 even, but that has nothing to do with the condition of the motor; just becasue you're running 230's doesn't mean its that much better pur se.
What you want to look for is the consistency of each cylinder. If you get something like:
210-215-180-205 you could be looking at almost anything.. but I'd target it to the head gasket first.

Keep a close eye on the reader.. it come sometimes slowly decrease, make sure the needle is still before you make a read.. this can sometimes take a few seconds.
