cam bearing cracks - Alfa - johne
When changing the cam belt on my AR146 ti (2litre twinspark engine, 100,000 miles) I noticed the cam bearing caps were showing signs of cracking....So, I bought a second hand head which has less than 70,000 miles on it and the same bearing caps were cracked in similar ways. I'd not heard of this happening before, so have I just been unlucky twice, do people not notice the cracks, or are they not a problem (I hope). Do cracks ever appear on other manufacturers' aluminium cam bearing caps?
