Engine didn't miss a beat in that time except when the O2 sensor needed replacing near the end of that time. [Reply]  [No Email]

Timing chains LOVE clean oil. The customers I've had over the Years ( 37 ) who changed engine oil @ 3000 miles Never had timing chain & gear issues. The folks who 5K to 7500 miles would need a new chain at 90,000 to 100000 miles.. For those of you who say OIL is better now & shouldn't be changed @ 3000 miles, when it come's to timing chains I disagree... I feel the same is more of a issue today with all these over head came engines with 2 or more chains. [Reply]  [No Email]

Usually those rely upon hydraulic chain tensioners to keep the timing chain tight. The dirtier the oil the less tension the hydraulic tensioner can apply, the looser the chain the more wear it causes. Ask Chrysler and Toyota about that. [Reply]  [No Email]

I agree with the oil changes at 3K miles, for the cost its just cheap insurance - especially on older carbed engines and throttle body fuel injection. [Reply]  [No Email]

Back alott of years & the parts Book doesn't really say? I thought in the car line they went to all still in 1990 But now all the # have been updated to dual roller chain?? So I guess?? If it has a single older style chain it could very well have the plastic coated gear on the cam.... [Reply]  [No Email]

I'm getting the occassional miss at extremely slow idle that makes me think the timing chain has some slack in it. Runs great at higher RPMs with centrifugal force taking the slack out of it - just like all the others. Everyone of them would eventually get worse until it jumped time or had some other issue that popped up. Any way to check this without tearing into it? [Reply]  [No Email]
