anyone here done these test often? i was curious if good test results can still be misleading. my motor has 83k hard miles. and blows the dip stick out but, only about an inch. i replace the valley cover hose with a home made catch can that is working pretty good so far. the motor is pulling 15hg steady vacuum. oh, i have no oil consumption problems either and the plugs look great.
i have been spraying the motor with 100w shots for a while, this season alone i have over 28 1/4 mi passes and i spray it all out, no progression.
i passed the compression test with unexpected results...
#6,8 cylinders developed 195psi hot, the rest were 200psi hot. while viewing the gauge for pump up, i cranked the engine 4 pumps on all cylinders.
the leakdown test was done with the engine cold. {overnight}.
the results were between 90% 92% for all. i would appreciate any seasoned experienced opinions.
