Just wondering what engine components (other than sensors and things) could need replacing around 100,000 miles? Im about there... THANKS

-Timing belt
-Starter
-Altenator
-Waterpump
-Powersteering - I hear they are a common prob. on GA's... mine still works at 60k

Those are just possiblities though... I've got a 89 Buick Century with 189k on it thats still turning the original power steering, waterpump, starter, altenator, and A/C compressor - which STILL works. I wouldn't sweat anything too much... stuff gets used and it wears out, not much you can do to predict what and when.

Edit - The timing belt you should have done BEFORE it wears out... that can be expensive!

we have a timing CHAIN, not a belt, so unless a link breaks....

might be a good idea to at least have it checked out though....

I thought the 2.4's had a belt, and the 3.4's had a chain? Is this true?

I would assume on a DOHC design like the 2.4 a belt would be used... as they are in most OHC applications. A 3.4 has a timing chain.

Nope we have a timing chain too and it is located right under the oil cap. I just replaced mine and it definantly needed it. I'm around 120,000 miles. Nothing else needed replacing in that area. All the sliders were fine and so was the tensioner.

Strong as hell but also heavy.

What all was involved in changing out the timing chain?


Ive already replaced the water pump (800 dollar job), alternator, tranny fluid, coolant, power steering fluid etc...

Ive got an MSD ignition on the way soon, so when that arrives I will change out my plugs/plug boots as well.

It was a fairly easy job. Put engine in TDC (Top Dead Center). Remove coolant reservior. Remove Drive belt. Support the right side of the engine. Take off crank shaft pulley. Take off motor mount. Take off right side wheel. Take off fender lining. Drain oil. Take the timing chain housing cover off. Rotate crank till camshafts timing pin holes align. Push tensioner down to lock it. Finally take off chain. $800!!!:wow: Man I got all sorts of things done to my car for $439. Timing chain, Timing Housing gaskets, Tensioner, Tensioner shoe, Water Pump, Exhaust cam housing gaskets, my Pacesetter headers put on, Coolant, Oil, Oil Filter, ****ty Weld job... There is more but I can't remember what.

My exhaust cam leaks oil as well... Do you have to take that timing chain assembly off the pull off the exhaust cam? I know that could be changed...

HID Ballasts, projectors, and bulbs... Send your housings this way and I'll send you my stockers. That way you don't run the risk of your lights going out in the middle of the night. My lights have 43k on them, so you're good for a couple of years :p

:stupid: Ahhhh yessss, and perhaps I should replace my blinker fluid, muffler bearings, and bend over to pick up the soap at the same time... :D

You got the headlights if you still want em by the time i sell the car, by that time though im sure some genious will market much better versions... And, if my car keeps breaking, i may not be able to afford to replace it untill hell freezes over or I win the lottery.

So long as I still own my car with no plans on selling it in the future, I'm game for them!!!

Did you do anything to the tensioner after you locked when you were ready to put it back in? I put a new chain and tensioner on and the engine now sounds like a diesel engine when idling. I don't think the tensioner is working at all.

When you install it and the chain is on you have to press it down and it will unlock the tensioner and the chain should become tight.

I tried that and neither the new or old tensioner would unlock. Was it as easy as clicking a ballpoint pen? or much harder?

I can't say for sure but I think he said it was pretty hard though...
