Want a diagram of the timing belt on a 95 pontiac grand prix with a 3.4 v6

The 3.4 is very difficult. If it has the twin cams you will need to have a very clear process worked out for you. One cam needs to be held in place while the other cam is adjusted and requires a special tool to accomplish. If you get it wrong it will run but knock like crazy.

What engines will fit a 1998 grand prix

You will only be able to fit a 3800 engine in this car. If you would really want to swap a different motor a 3800 superchanged L67 engine will fit but you will need a heavy duty tranny from the 3800 motor and you will also need a wireharness injectors and harness and also a PCM. You can find these motors for a pretty cheap price on moradparts from ebay. They also have their own website. Very very good place to buy used W body GM parts

My 1997 Pontiac Grand Prix GTP has an oil leak located on the firewall side of the engine. It's a small leak (2-3 drops a day) but very messy on my concrete driveway. How can I fix it?

Try some motor honey. It can be bought at most part stores, advanced auto, autozone, ect. It worked for my 95 Grand Am when I had a leak in my oil pan gasket. Hope this helps
