Well my car started running shitty this weekend, really bad compared to how it was. I did a compression check today and it wasn't as i had hoped.
car is a sohc 97 civic dx with a 98 ex head/intake manifold with a greddy 15g turbo kit.

Compression
4 - 65
3 - 110
2 - 200
1 - 200

my piston rings are blown on 3 and 4, you should see the oil my cars dumping out the valve cover nipple. i dont know much about engine internals so i need some help. should i just replace them with OEM?(im going back to all d16y7 motor, ditching the ex head, its been nothing but problems since i swapped it on, or should i get something else? i don't have alot to spend, this is my daily driver, if it wasn't i'd be building the block up. i just need something that will work good for daily driving but also if i wanna boost it higher than 6 psi something that can hold it


*reason they blew my charge pipe popped off friday on the highway, pulled over and fixed it but as i was i disconnected the wastegate by accident, got back on highway and it hit 14psi

any insight is much appreciative

bump for the morning peeps

Well, it's according to how bad the engine is. At 14psi, you could have broken some ringlands, scored the cylinder walls, ect.

devonic

true, i didn't think of that

Tear it apart, and see exactly what happened. I dont think it is the EX head that is to blame, would of happend with any stock head, hitting 14psi untuned. If its scored and needs to be bored out, you will most likely need to get after market pistons. Personally while it was apart, I would get pistons, rods, and ACL bearings. But if you dont want to build it, hopefully you only need new piston rings. GL

If its really bad just drop a B18 in there.

i'd like a dohc in, but its out of my price range, and the turbo makes up for that. i just need to find a complete engine, a d16y8 preferably but i'll settle with a d16y7 if i can find one
