I have just bought a 2007 Hyundai Santa Fe 3.3 with 11200 and I'm thinking of flushing my engine because I'm getting chain slapping when I first crank it I have hydraulic tensioner and from what I've been reading up on this could solve the problem so I don't have to rip into the motor to change the hydraulic tensioner what do u think

At first you'd think an engine with only 11,200 miles wouldn't need a flush, but then again that car did a lot of sitting which is not good. I recently bought a 2012 Santa Fe with the 3.5 and it only had 17,784 miles on it. Luckily the engine is quiet. I've read good things about BG products...

I've read that the hydraulic tensioner is a faulty design
Tensioner failure is blamed on two things. Lack of oil changes which causes excess sludge build-up in the oil passages to the tensioners which in turn causes them not to pump up quickly enough and there is also a mechanical failure attributed to the teeth wearing out on the little shaft (don't know the official term) that keeps a constant tension on the chain.
