Have a b16a head on a b20b block, missing bad, compression tests results: 180 150 90 0 ( 1 2 3 4 respectively in honda order) any idea what compression leak could be or next step in diagnosing? Any help appreciated.

 

sounds like you have some bent valves

 

or bad valve seals

i would like to know how bad valve seals could cause 0 psi. i would vote bent valves, damaged cylinder.

also have you looked at your coolant? oil? possible headgasket

 

my bad i thought it was 90 90..i read it wrong

90/90 would make me think blown headgasket

 

no oil in coolant or vice versa.
there is a large oil stain on the block under the head

did another test today and these were the results

dry (order 1,2,3,4 honda order)
160, 150, 60, 0
wet
190, 180, 90, 30


headgasket was a new cometic mls 84mm non vtec block to vtec head head gasket
used arp head studs and torqued down to proper specs

gonna have a differnt shop tear down the build tommorow and see whatsup
