Timing chain

[standupjskiguy]

I have a 14k GN. I'm the original owner so I know the mileage is real.
I saw another post where they said they changed the timing chain on a 14k GN.
(http://www.turbobuick.com/forums/threads/ac-blows-out-floor.410059/)
I know we had the chain changed on our 85 T-TYPE at about 100k but should I
be concerned with my timing chain and sprockets on a 14K engine?

In your situation I'd only change it if you were pulling the front cover anyway. I pulled mine on an almost 60k engine and I thought it looked pretty good. (pic attached) These chains have lived in cars with much higher miles. You could always pull the oil pan to see any of those nylon teeth are laying in the bottom. If you see any I'd change it. If your car lived those 14k miles a 1/4 at a time like Vin Diesel lives his life then it may be in bad shape. Otherwise I'd personally wait.

I have the same question 15,000 miles and debating change it or not?

Thanks for the input. My car has had an easy life, no mods, no trips down the quarter mile.
I've never even done a burnout. So I'm not going to change the chain.
I remember the one on the 85 had some plastic missing off the sprocket but the engine ran fine.

If you do the work yourself, a timing chain swap is about the same price as a wrecker bill.



I'd change it (or at least the top gear) and switch over to the roller cam button and neoprene front seal.

My guess is your front seals are due for replacement anyway.. ..
