I just installed a stainless braided clutch line today, and I decided to change my spark plugs and run a compression test also today.

Has around 1500 miles on the head gasket, and I changed the plugs when I did the HG.

Here's the compression #'s from my first compression test on 4/16/06, a year before I changed the HG.

Cyl 1: 184psi
Cyl 2: 185psi
Cyl 3: 181psi
Cyl 4: 173psi
Cyl 5: 173psi
Cyl 6: 183psi

Now today the numbers were this-

Cyl 1: 185psi
Cyl 2: 185psi
Cyl 3: 182psi
Cyl 4: 181psi
Cyl 5: 180psi
Cyl 6: 183psi

I used a MAC digital compression tester, all of the spark plugs were removed, engine was hot, EFI fuse was pulled, throttle was held wide open, and I only cranked the motor for about 4 seconds on each cylinder. This is on a 20 year old motor with 123K original miles on it. Not too shabby if you ask me. I was pleased with the results.

And my exhaust is alot louder with new plugs, a definite notice in throttle response and sound. The NGK's that were in it only had about 1500 miles on them.
