The GTV6 2.5 I bought off EBay is supposed to have a "hot" cam in it. It has a rough idle, but that may be due to poor vac and tune setup. Having pulled out a NOS system that was half a**ed put in and some MSD ignition parts there is no telling what is really in there.
I am putting Gregg's silicone hoses on tomorrow, and will be taking off the valve covers to look at the cam and see what I can see. Where should I look and what should I look for? I will be putting some covers that I have bead blasted and painted to make the engine at least look cleaner.
Also how can I determine what the compression ratio is without taking the heads off? Would a compression check give me any clue? I also plan on doing a leak down test to give me an idea of how bad the PO's nitrous fiasco was on the engine bits.
Any help would be appreciated and i will get some pictures to post if I can figure out how to get them on the BB.
Thanks
Marcus
