i need some help about my hatch i put a rebuilt b18a1 in it last summber and i burnt out the valve seals so it smokes when it been sitting for 5min or so anyways i just checked my compression and all cylinders have only 130 PSI no more no less but shouldnt it be more like 175-190PSI? what should i do???

Snoopy

did you do the test with the engine warm and throttle wide open?

89civicB18

warm yes but not with the throttle wide open what does that do?

Snoopy

the throttle has to be wide open to get correct numbers. also try the tests with a capful of oil in each cylinder.

ok well i just checked agen with the throttle wide open and a cap full of oil and still no change car was warm too still only 130PSI could it be my catback muffler system? its 2 1/4" but still the motor only has 21xxxKms on it since the rebuild and it was only the bottem end could my head be done? let me know what you think

Snoopy

forgot to mention this, did you remove the ecu fuse and have all the plugs out?

the actual numbers themselves arent as important as the variance between them. as numbers will differ depending on lots of things, even from different compression testers.

89civicB18

yes i pulled all the plugs but not the ecu fuse and the numbers did not move at all thay stayed at 130psi wet and dry all cylinders ?

try the test again following these instructions: http://www.c-speedracing.com/howto/c...t/comptest.php

Sounds like the valve stem selas were not replaced.
