He is not willing to run a leak down test for me.
ok hes an idiot...

you dont do a compression test at wot...

Have him give you the numbers for the dry test. the wot will give you false numbers.

For those who think variable valve timing has effect on compression test numbers go read about vvt. vvt takes affect only when the vehicle is running and will have no affect on a simple compression test...
