Again thanks to all for your replies.
Well, i lifted the valve cover today and the intake cam follower bearing had broken in pieces. The resulting particles have damaged the cam shaft itself, most of the bearings on the camshaft and the rocker arms. I will post a few pics later.
The mechanic and I spent a few hours going around to the bearings shops trying find replacement bearings for the camshaft but could not find any. He reckoned it might be possible to repair the camshaft itself but that a new one would be better. There is a fair chip taken out of the exhaust. Any thoughts there?
I got a quote from KTM Lima for a replacement cam shaft and bearings and rockers for around US$600 and 20 days. However the mechanic forgot to say it was the 400cc LC4, so the quotes are for the 625, 640 or the 660. Would anyone have an idea if they would be the same?
Is there any chance that there are other problems lurking in the engine that I havent come across yet? I havent looked at the piston yet. What about all the metal that has been floating around (I even found an intact pin from the cam follower bearing in the sump oil). (Havent looked at oil filters or oil in the tube yet).
Thanks,
Eamon
