Oinkjackson, you were lucky to get it away from the dealer. Parts haven't done you in, but the others are right. The Dealer would have squeezed you for labour.
My poor girl is sitting at just over 157 000 and I just had the timing belt changed. Come to find out, the belt had been changed before, no one knows when, but the pump and the idler have not so now I'm waiting on parts to have the car go back into the shop again and I still need to get an oil change.
The never ending aveo story...I took the car to a mechanic yesterday, hoping he would check the oil pressure and sending unit; he did neather. He changed the oil and filter (both of which I provided) and called it cured, having found some fuel in the oil. It wasn't fixed; he hadn't even let the car warm up to reassess the oil pressure light at low idle. I took the car to some more competent mechanics this morning and they said that they could check the oil pressure but if it was low pressure there wasn't much I could do, anyway. They suggested 10w30, STP, and a new sending unit for a cheap alternative. I have a friend that will check the oil pressure today and then, I'll go from there.
By the way, where is the oil pressure sending unit?

Its on the back of the engine (nearest the firewall) down by the crankshaft pulley.
i would like to know why there isn't much you can do about low oil pressure? what did they mean by that?
I think they meant that it would get expensive and wouldn't be worth it, referring to worn crankshaft bearings.
except the oil pressure light is directly off the oil pump. So you would most likely be replacing the oil pump, on the front of the engine, not rebuilding the bottom end.. i have seen cars with terrible terrible knocking from completely worn out bearings and still have high oil pressure.
Mr. rabbit, I suspect that you might be right again. I had no problems with low pressure before the big belt failure. I'm thinking that maybe some debris from valve stem seals etc. might have entered the oil pump and caused some mayhem. Although I haven't had the opputunity to check the oil pressure yet, I'm guessing that it might indeed be low because I've heard some knocking, possibly the lifters, in the engine at times. As mentioned before, the car has only 64,000 miles on it and I doubt the bearings are shot.
You can hear the lifters on a perfectly good engine. I'd change the oil pressure sensor to see if that fixes it. If not, you know you actually do have low oil pressure.
I leased Pontiac Wave from September 2006 to August 2011.
Help! I have something mixing with the oil, thinning it out and prompting the oil lamp to flicker and come on steadily when the car is hot and at low idle. I've changed the oil and filter three times since the head work; it's always ugly, diluted looking, with a slight green color similar to the coolant, and always has a wee milky swirl like two fluids seperating, when stirred.
check the coolant level and color? check the gas flow?
