03 3.4l Possible head gasket problems
Just did the tests for the heads using a pressure gauge. I got a reading Ranging from 141PSI to 147 PSI for all 6 cylinders, which is great! I didnt have a 10% difference between cyclinders so that eliminates the possibility of a head gasket issue. I then tore apart the engine and changed out the lower intake manifold gaskets (took forever to get the surface area cleaned off.) I put on THE RIGHT STUFF gasket building RTV on the sides and nice new rubber and metal Fel Pro gaskets. Hopefully it will last the life of the car! I reassembled everything and it has been curing for 24 hours now. Before I start it I want to flush out all fluids. I need to know if i should flush out the mixed fluids by:
-Filling my engine with cheap oil, Draining it. Then REfill again with cheap oil, Run the engine, then drain again. Refill And call it good.
-Going in to get a power flush of the coolant system BECAUSE there are trace amounts of gasket remover in the system even though I took all the precautions by covering exposed areas not intended to be cleaned. I figure if I go in for a power flush I can get any trace of it out, miminize gasket damage, and get all of my garbage dexcool out!
Any suggestions feel free to post.

So I did the oil change twice, once after the inital repair job then again after I let it run abit. Id say I got MOST of the coolant out of the oil, after my next change it will be gone if there is any left. I had a coolant flush and added some protective chemicals to the mix. My car runs awesome now, so glad i fixed the POS. Sadly this is my last GM car, for ive been kicked in the sack too many times by GM to stay with them. Probably going foreign next time.
