Oh snap! I think I might have skipped that step! Looks like I'll be doing it again!

 

you are going to get the same numbers. i tried that before and is the samething no difference at all. oh ya just the smell of gas.

 

Do the test while the engine is warm.
Remove the fuel pump fuse.
Do it at WOT.

Different gauges give different readings. Also, warmer ambient temps give lower readings.

I also remove the plugs from the other 3 cylinders while doing the test, to minimize cranking effort.

 

I just redid the compression test and this time at WOT. The numbers were identical.

 

just like i said. you will get the same numbers. are you sure you did a k20a2 swap and not a k20a3

 

Positive.

Apparently the engine must be getting tired. We plan on selling it within the next 2 years or so, so it doesn't make any sense to go and rebuild it.

 

was the car warmed up to operating temp?

 

Yes. I'd like to do a cylinder leak down test, but I don't have an air compressor nor the leak down gauge.

 

hows the oil consumption? is the car smoking?

 

It is going through a quart (Mobil 1 synthetic) every 3K miles or so. No, it is not smoking at all.
