My compression test - Pls comment
My compression test results
1 - 90 psi
2 - 80 psi
3 - 90 psi
4 - 85 psi
5 - 90 psi
6 - 85 psi
My EGR is making a hmm / vibrating noise after I shut off the engine. (not sure if that is normal)
Let me know your thoughts. Thank you.

That's why. Take all the plugs out and burry the pedal to the floor. It will spin over faster and let more air in.
then you'll get the true reading.

ps. I have family in Oshawa they work at the GM rail yard.

I will try that. Read the proceedure in the Haynes (after of course) and it also mentions killing the fuel flow with the inertia switch.
Ps. Rail yard is one block from work. My dad retired with 40 years from GM and I worked there as a student. One summer (1990) I spent 2 weeks in the railyard. (never really got to meet any of the employees though)

Okay...
Lowest was 142.
Highest was about 149.
The only thing I noticed was that the pressure guage didn't jump right to 14x on the first crank.
It jumped up each time for three cranks and then maxed at the setting.
Like 100 125 140 ....if you now what I mean.
