You need to remove cylinder head to confrim if there are any major damages to it. A broken connecting rod can cause damages to the head too.

You cannot repair a hole iin the cylinder block.

How did you know that there's a hole on no.4 cylinder?

If you went thru the head you will know if there's damages there

can I just replace the bottom

To get there-you have to remove the head or the crankcase cover

Anyway to fix this fast-Get a new engine

Yeah I took it to the mechanic and he said that there is a lack of compression in the bottom end and that there is a hole in the wall on piston 4. He didnt talk about any damage anywhere else he just explained that I would have to replace the bottom end.
