Hi all,
Just removed my cylinder head for the first time. I cleaned the mating surface on the block, and noticed scuffing on many spots. I attached some images of it, and would love for a veteran to weigh in on the severity. The engine is a D15B1 (Civic 3D STD).
Thanks in advance!

 

Looks kind of normal for those old style of head gaskets.

Also looks like you have been leaking a lot of oil, for a long time.

 

Yeah, every cylinder was black from carbon deposits, I could barely manage to get it to this level lol.
I think this might be the first time someone’s opened up this engine since it left the factory, 180,000 miles ago.
Could a new head-gasket solve the oil leak, you think?

 

I would replace every gasket I could... but that is me, no fan of oil leaks.

 

Sounds good, thanks for the advice!

 

Looks like the gasket came off pretty clean.
maybe some CRC head gasket remover spray will clean off the remaining residue or a Roloc bristle thing for a drill.

since you have the head off, you should clean them up and do a flatness check to see if you need any machining.

the front of the engine look like it’s painted wrinkle black! So much caked on oil from a leaking valve cover most likely
