My 97 aurora has trouble starting and while turning over it makes a horrible knocking sound and backfires through the intake but then it starts and runs fine. it smells hot all the time but it stays around 200.im not a mechanic but was wondering if maybe the head gasket could be leaking into the combustion chamber and causing it to hydro lock making it hard to start?

I have had this problem with my 98 aurora and have replaced all the same components. Temp gauge routinely shows 200 on highway (Fine) but in the city in stop and go will get to around 245. I installed a switch to manually turn on the cooling fans by connecting the ground to pin 86 in the relay for the fan(s). Otherwise the fans will not turn on to 245. This fix works but would like to know an actual solution.

SOURCE: oil burning when start up.

There are a couple of things that can cause this.
1) Engine oil over filled.
2) PCV valve defective.
3) Engine valve seals damaged or broken.

Is this a high millage car?
Let me know.

I had the same problem with my 96 Aurora. I guarantee it's the fuel pressure regulator. Had mine replaced by GM dealer started like a new car

You don't have to remove the intake.You need to remove the coil packs and starter bolts,wires from the starter posts and twist and turn you way out.
