I just replaced my head gasket cause i was puffing white smoke like i was burning antifreeze so I replace the headgasket and resurfaced the head and had the head pressure tested.

Now after putting it back together it started up and runs fine but it is now puffing blue smoke like its burning oil yet its not missing so that leads me to believe the machine shop that tested the head didn't check the valve stem seals and one is bad.

Is there a way to replace the valve stem seals without having to pull the head again?

so i found another thread about using compressed air to hold the valves up so I dont have to take the head off again.

is there anything else that could be causing this besides the valve stem seals? I really dont wanna change them if i don't have to it doesnt sound like a fun way to spend a weekend if there could be something else causing the problem.

If it's the valve seals, you'll see smoke when you firs start the car, or after vacuum conditions like if you've been sitting at stop light and then accelerate.

Use the compressor to hold the valves up.

This valve spring compressor by far works the best. Worth every penny.

Apply vaseline to the inside of the keepers when you reinstall them. That'll make them stick to the stems while you uncompress the springs.

that is exactly whats happening smokes when i first start it up then it only does it after i stop and sit for a bit. It will also smoke under heavy acceleration.

My mechanic says that i should also replace the valve guides but that i would have to remove the head to do that so I'm looking at spending an extra 250 to do that.
Is this necessary in your opinion? or should I replace the seals first and button her back up and see if that fixes it?

PS> will that tool work on a h23a1 also or only vtec?
