    Burning oil

    I got a new cylinder head a while back but after i put it on i noticed that when i press the gas pedal hard blue smoke comes out the tail pipe. I read on here that some said it could be valve seats but since my head is rebulit, what else could cause the car to burn oil? Its only under heavy exceleration because when rolling normal no smoke comes out. Oh yea n when i turn it on in the morning if i dont let it sit for a while a whole bunch of smoke comes out but then stops.

    Valve seals. That can usually cause that to happen. Unless your piston ring just decided all of a sudden to go out on you. You sure they rebuilt it right?

      Have you done anything on your bottom end. It's maybe your piston rings...

                Im sure they did a good job so i guess its the rings because i havent done anything on the bottom. But what could cause them to just go out like that? Before the new head it didnt do that. Maybe it is the valves? I dont know.

                  Common sense dictates if it DID NOT do that before you took off the head and it DID do it after you put the new head on. That would mean the head is most likely not done right or you did something wrong.

                    could also be your valve guides. They might not have done em right or at all. Usually they bore em out,install liners, use valves with bigger stems, or replace the guides. Dont know which is best for a honda head.

                      How many kms/miles since the head was put on?

                      If it was seals it should smoke on start up and on heavy engine decel (engine braking)

                      More then likely you rings are toast. No more leaking past the valves so there is more cyl pressure.

                        To settle if its his rings do a compression or leakdown test. That will tell you. And it will eliminate quite a bit of things that could be wrong instead of all of us guessing where its at. I am still gonna say its somewhere in the head where they screwed up. But those two tests will verify what is going on.
