Ok I’ve got a 00 prelude with 150k on h22a4 it still runs great...only thing is every now and then it will blow oil smoke out the exhaust. Just for a split second then quit. So my question should I have the head rebuilt? Or should I go h23a swap. All I see is problems with everyone doing a swap, and mostly using h22a4 parts anyway. I got the h23a vtech engine priced at 1,450.00. Or should I just have the head rebuilt and head gasket replaced? What’s some opinions on my situation? Just for reference no I don’t race it, but like having the power there if needed. Thanks for any input.
