i have 150psi compression in 3 cylinders and 60 on the driver side cylinder i thinks thats cyl. 1. i dont think it is a headgasket because ussually it will be more then one cyl with low compression. so my only guess is rings or valves not seating. i forgot how to do a wet compression test. can anyone remind me. and another dumb question does a 90 civic dx d15b2 have 2 fuel injectors? i dont understand the pgmfi thing but from what i read on alldata it has 2 fuel injectors i just want to confirm this and could i use rc 440s made for a 92-95 civic. is there a harness? and will they fit in the holes.

you need to buy a new engine. it wont last long maybe another month

it could be any one of the things u mentioned including head gasket, like they said buy a new engine if u want to keep the car

or dont be a *** and pull the head off to find out on your own.

Oh gee I wonder who this is

why wont it last long? and could the low compression in the cyl be causing me to get high CO's

Yeah, probably. The fuel charge isn't being compressed enough to get a complete burn, so it's pretty much like spittin gas out the tailpipe and clogging up your cat.

hopefully my engine isnt cracked or anything. im going to do a wet compression test tommorow and a leak down test. i would rebuild the whole engine but i have limited space and only 10 days to get it fixed so i can register it.
