Low compression on cyl 1 need help
Ok so I recently boosted my 94 integra. It has a jdmb16 and a built gsr head Well now I am layin down 220whp on 8lbs, but upon doin a dyno tune found that cylinder one has very low compression and the bottum end of my motor is stock.
here are my comp levels
cyl 1=160
cyl 2=200
cyl 3=210
cyl 4=210
After comp test we stuck a snap-on camera into block. cyl walls looked fine and pistons had minor carbon build up but otherwise looked normal. so upon a leak down test I found air to be blowing out of my intake TB and exhaust. I believe whoever built my head did not seat my valves correctly or do a proper valve job. valve springs and retainers are crower. Would my assumption be correct on what might be the cause of my comp problem? This is my first Honda so I need some help.
Thanks
