Having problems with your 2000 Daewoo Lanos ?
Last May I had the timing belt done by a professional repairer and now there is a problem with the cam box - it has broken up and lost the oil seal.
This is a little heard of problem and the garage's theory is that either the cam jammed or there was a blockage in the oil galleries, causing overheating and a subsequent break-up of the cam box. The engine has not been stripped down.
I don't accept the 'jammed cam' theory as the engine never faultered and we drove 2km home before we discovere
It is very possible that there could have been a relation between the timing belt being serviced and what happened recently.When the engine is opened up to replace the timing belt and certain gasket contact areas are grinded down to achieve a smooth flat surface it's very possible that that oil galley holes weren't covered to protect from material getting in there.This could have caused the failure.Also, it's very possible that the timing belt tensioner had failed after the fact and the belt acheived enough slack to jump off the sprockets which in turn could cause the cam to slap against the pistons and damage the cam itself.This would actually more than likely damage the pistons too.I hope I could help.....rate me accordingly..
The blocked oil galleries is the best scenario here, lack of oil would be the only thing that could cause this, there is no way changing a timing belt could result in a frozen camshaft, with 45 years of auto repair under my belt i reject that theory, lack of lubrication is the reason without a doubt.
