Compression Assistance

[Apoc Bane]

Hi Guys,

I bought the 25 dollar harbor freight compression test. I can't seem to test the passenger side because the adapter is too short and when I try to attach the gauge side connector, it hits the exhaust manifold and won't attach.

I got the drivers side done

395

Seems to fail the 80% - lowest can be 324? no?

Is it alright to loosen the exhaust manifold on the passenger side to do the test?

Thanks

Can anyone recommend a shop in the bay area (cali) to do a rebuild>?

Can you extend it with a brass or steel pipe nipple?
Post a photo of it.

used the same set. I had to test the one passenger side nearest to the firewall from underneath. All the others should be accessible though. All my numbers were around 425.

I went back out and got 3 more done, I'll have to do the passenger closest to firewall tomorrow with the sun.

Looks like two cylinders more than 80% out so far.
