timing belt

ok so i was flipping through my owners manual yesterday, and i read that the timing belt on my 95 lumina 3.4 should be replaced every 60k miles, well im closing in on 130k and im rollin with the original timing belt...my question is, is there any warning before it gives way, is it true that to get to the timing belt would take an entire weekend atleast, and is it worth doing when i plan to sell the car in less than a year?

You are WAY overdue, and letting it go could result in bent valves and a toated motor if it slips. Technically, the 3.4 DOHC isn't and interference engine (where timing belt failure causes the piston to strike the valves) but it is. The pistons have a bad tendency to rock in the bore which tightens the clearance and they more likely than not WILL strike the valves if the belt goes.

And when you put the belt on, get the kit that includes the pulleys with the belt. Available at NAPA and other "real" parts stores.

I used to be on www.60degreev6.com alot, there is a walkthrough on the site for the timing belt, and quite a bit of other maint. Also the guys there found that www.rockauto.com is a really good place to get timing components. It used to be www.gmpartsdirect.com but they got greedy and jacked up their shipping through the roof.

i am ready to buy a 92 lumina z34 with 110000 miles on it and the seller told me the timing belt needs changed and he showed me the belt was replaced 20K miles ago and now needs a new one but the belt isnt broke its just shavings from the belt on the belt cover. would the car be alright if i just replaced the belt

I had exactly that problem. That's why I recommend the kit with belt AND pulleys. My second belt lasted about 20K before the inner 1/4 inch was destroyed. That's when I put on the new pulleys...

is that expensive or can i do it with atleast 100 dollars and do i need other work on it for it to run or would it b alright once i get the pulleys right
