I am going to tighten my head bolts as a possible easy fix for an oil leak
on a very high mileage 1990 325is.

It seems to be leaking between cyclinder 4 and 5. The leak is on the
exhaust side.

One tech recommended tightening the 4 head bolts just in the area of the
leak.

Another tech recommeded tightening all of the head bolts, in the proper
sequence, uniformly.

Which is the better way to do it?????

I do not have the money to get my top end redone, so that is out of the
picture for now.

Thanks in advance.
