Hello Scottie, can you help? Would love to hear your opinion. Half a year ago I bought a 2000 Camaro SS m6. It have a 5.3 iron block with 383 wiesco stroker kit, PRC heads, cam, what I believe to be an ls2 or 3 intake and other supporting modes, which dynoed at 485hp. I drove from TN to MI About 500 miles if not more on it just fine. Then one day I was doing some work on it and drained coolant. When added it back up I messed up and didn’t add as much as I needed. Long story short I wasn’t on highway or anything, near the house when I caught it overheating. Temp went close to 230-240 and I had to make few stops to cool down to get it back home. After that and adding rest of a coolant I began having strange issues. First is that w coolant itself. It seamed to be a never ending adding of it ever since. This is what the first prob. Let’s say you added a coolant to a radiator neck and overflow have it at full cold, then you drive for 100 miles or so and then next morning rad needs another quart to get to where it was, however overflow now at full hot. However if drained back to full cold and added whats extra back to a radiator radiator mark does go up but not all way to where it was before the trip. Another thing I noticed that if those 100 miles were hard driven like these cars should be driven to enjoy then my oil level gets down to a pint. If I drive it gently just cruising no oil is used. Now as Disclaimer when I bought her and drove 500 miles it was a winter and I never was hard on her at all, so I can’t say if this oil thing is some I got her with or not. However coolant was checked before that trip and never needed to be added the next morning. And lastly one last weird thing: because of those issues I been watching both coolant and oil closely for two month checking them after every trip to kinda give myself a statistics. Having said that I prob checked oil 30 times in last 3 month and twice I had a very strange experience w it. On a dipstick right above oil level after about an inch or two away from it closer to the top I have found coolant. Almost like it drips on a dipstick but how? What do you think is happening? Now here are the things I’ve done and their results. I have done compression test twice to different days weeks appart, doing each cylinder 3 times each time, holding each for 4 or 5 strokes. Both times engine was almost cold since after warming it it takes quiet some time to take all plugs off. All cylinders pump almost identically 1 stroke 110ish 2-160ish 3-180s and stoping at around 195-200psi. None is behind others all literally almost identical. Spark plugs to my inexperienced eyes based on online information looked normal though I’ve replaced them anyways. Only one had oil on its thread however the element and tip part of it was identical to the rest of them. I did or should I say tried doing a leakage test. That went inconclusive because as I tried holding that tube above the radiator neck for some reason my test wouldn’t come out as peoples online and I kepped on loosing the liquid down the radiator instead of it staying there and changing or what not color. So that was inconclusive. All I can say is that while holding a tube over the rad as it drained into it it did changed in color from good blue to somewhat of deluded dirty and light blue, almost starting to change to loose that blue vibe. But then again, I never managed to finish the test as intended. I also replaced and tested radiator cap and Replaced overflow tank. I had oil out of car twice in a see through bucket for weeks looking for coolant presence and their separation but nothing at all was found. I was hoping one of them had a leak preventing a pressure build and further preventing a coolant to drain back to radiator. I’ve also pressurized rad by pumping 17 merc in it and watch over it. What I found was that if engine is cold and rest is done then it holds 17 for half hour untill I take it down, however once I ran a test after idling it for 30 min, and it went from 17 to 14 in about 15 min when I stoped the test. I know the law of Pascal but Does it seam normal? So my biggest question is what is going on w it?

Could of head gasket been overheated and raptured at the part of it which does not loose compression but does allow coolant to escape? And what is up w inconsistent oil consumption? Could of heads developed a crack? Did I overheat and damage valve guides and seats? Lastly few days ago I stoped driving it because of a third what could appear to be unrelated but (I believe they do) event. You see ever since the overheat, I’ve noticed gradual fuel consumption increase and at idle the car would put out gas smell in garage but all still seamed normal as it is after all build and crammed stroker. However more time went by more fumes it pumped at warm up and recently when I started her up, at some point I could see half of a car let alone breath, even though idle seamed just as it was before. I have a small 50$ scan tool which shows min info, I plugged it in but couldn’t find anything unusual other then what it appeared to me it’s fuel trim and air to fuel ratio was jumping from 13-22 at idle. Vacuum reads 15-16 at idle instead of 20. Both O2s active. Maf changes it’s value gradually w throttle, same as Tps. Haven’t checked IAC. Lastly When I went to raise it, I saw a two coolant drops on bottom of water pump w a trace of them coming from around its pulley. At this point I know I have problems but I don’t exactly know what it is. I know it’s a lot to read but if you’re reading this then you took your time and I appreciate this. Please help with your advise. Thank you
