I have a 97 Camaro RS with a 3.8 V6 in it.  The car has been giving me problems left and right.  I recently found out that the reason for this is i either have a cracked block or blown head gasket.  If the block is cracked should i just do away with the car seeing that a crate v6is right at 2 grand?

Are you sure your problem isn't a melted plenum? The late-gen 3800's have a polymer intake plenum that readily "goes away."

well its skipping while idleing and i have two trouble codes coming up. P1406 which is a bad egr valve and P303 which is cylindar 3 misfire. and im getting oil in the radiator also. plus its overheating. so if thats the symptoms of a melted plenum, please say so? i had a mechanic check it out and he told me cracked block or blown head gasket.

Oil in the coolant is synonymous with something pretty drastic...

hey guy i would get a 2nd option and have a compression leak down test. it could be several deferment  things that's causing this problem, some cheep and some expensive. if it does turn to be a caked block this a very poplar gm engine not just in Camaro the long blocks will be the same in a lot of them and you can pick one up with low miles {in a salvage yard that has been wrecked}a lot cheaper than 2 grand. if we can be any more help to you let us know.

thanks

I had a 3.8 that the intake manifold went south due to corrosion. That could mix fluids and was extremely easy and cheap to replace.

I should have said intake manifold gasket.

While you are there, grind the valves, have both heads surfaced and replace the lower plenum. Use a Dorman. It is cheaper and better than a GM.
