Question about 2001 Toyota Altezza
Compression test figues recommended for dual vvt-i beams
Posted by Anonymous on
There are no "correct" numbers for compression tests, as actual compression depends on many variables. The important thing is that it is not crazy low (less than 110 psi approx) and that all cylinders measure within 10% of each other (approx). Tests should be done with throttle held wide open and all plugs removed. Crank engine about 5 revolutions for each test. Comprssion should slowly build to max reading.
