Okay so I am having issues. some people tell me that I can rebuild my engine and everything will be fine. Then on the other side, others tell me I should just get a new engine. My valves are starting to make a lot of noise which I just had adjusted like 2 days ago and yet again they are getting louder. If I do an h22 engine swap what will become of my 4ws will i be able to keep it, or do you think that i should just do a rebuild on my b21a1??
