Heard a ticking noise on the engine DTS 2006 Norstar with 160K miles; took it to dealer, they are saying it is time to change the engine. I cannot believe it, I had a Buick LeSabre with 300K miles original engine and no problems. I am thinking it could be a rocker arm gap or the timing chain and should be able to get fixed without replacing the engine.
Any comments please?
How bad is the ticking. if only happen when you change the oil the lifter are bad. I have the same problem I just drive it like that. But if the noise is coming from the passenger side of the motor. You may need the timming chains guide and tensioner. I have 220,000 mile on my 06 I have done the timming guides and tensioner twice. Good lk.
