Timing Chain Wear
One might expect that low oil pressure indicates a problem with the oil pump, but that is not necessarily the case. Very often, using an out-of-spec motor oil, such as one with a lower viscosity than what is recommended by the vehicle manufacturer, will cause low oil pressure.
Timing Chain Failures on 2.0L, 2.5L Import Engines
Last month, we looked at the timing chain setup on the Audi 3.2L engine and saw how a lack of oil changes can adversely affect the tensioners and cause engine failure. We’ve also seen similar issues with the timing chain setups on the 2.5L 5-cylinder BGP engine that came out in 2005, and the 2.0L
Audi Engine Timing Chain Failure Due to Lack of Maintenance
If you’ve been working on cars as long as me, you’ll remember the first timing belt you did and thought, “what was wrong with timing chains?” It was only a year ago, when I was working on a 2005 Audi A6 Quattro with a 3.2L engine with a broken timing chain tensioner and bent valves,
