Question Asked: Does timing chain tensioner affect oil pump?
March 13, 2011, 01:04 PM
My son's 2007 Hyundai Sonata had an engine noise that was eventually diagnosed as bad timing chain tensioners. However, one Hyundai dealer repeatedly denied the problem, so it was 8 months before another Hyundai dealer admitted it and changed the tensioners. A couple of months later, the engine light and oil light were on and he was told he needed a new oil pump. By this time, the warranty had expired and he had to pay for the new oil pump and eventually a new engine. My question is this: Could the failure of the oil pump have had anything to do with the timing chain tensioner problem?
