Compression Results

[BurningRubber]

I changed my plugs today and did a compression test while doing so.

I unplugged all the coil packs and injectors, cranked the engine over several revolutions @ WOT per cylinder (all other plugs in place). This is how I was told to do it, is it correct?

Drivers side, #1 is closest to the radiator.

1: 162psi
2: 172psi
3: 170psi
4: 165psi

Passengers side, #1 is closest to the radiator...

1: 150psi
2: 123psi
3: 160psi
4: 120psi


Not too happy with the passengers side...

I guess spraying it is a bad idea.

124k on the engine by the way.

thats not that bad for 124k, i mean, honestly, after 120k is when i started having lil problems from here and there.

I would check cylinders 2 and 4 again just to make sure those numbers are accurate. 123 and 120 is a little to low.

mazen - Yeah I figure thats probaly where a little bit of my oil is dissapearing to, but its been beat on by me and the previous owner.

darkside - I re checked the first cylinder that came up low, it repeated the same results so im very confident those are correct. I was bummed out about those 2 cylinders.
