Installed my Inline Pro Headgasket and did a compression test on my car today and got 90,90,90,90 across the board. What could cause the extremely low numbers? possible error with the test? It was a cold start, Car hasn't been driven in months, but other than that it started right up and idled fine with the turbo/hondata, no cel's, no smoke, etc....Its driving me crazy.

 

BTW: engine is a JDM 2gen b16 with 3mm headgasket.

 

3 mm hg lowers it alot. Try agian hot and try another guage. should be well over 100 warm.

 

Also like 6 months ago i did a test on the engine and got 210,210,215,210, and the car hasn't been driven since.

 

any other opinions?

 

Do a "wet" test, shoot a little oil inot the cylinders, this replicates an N.O.T. test

 

I threw a little in and they went up a bit ~95ish..but all stayed consistent.
