I would like to preface this thread with the information that my car is mechanically stock except for the Trifecta Budget tune. The tune is setup to be turned on and off and other then the ping being worse with it activated it has no effect on the issues I'm having. In fact both of these issues existed before I loaded the tune.
Overheating Story:
So there I was, Driving home from my girlfriends house this fine Christmas morning. It was a crisp 34 degrees outside and I had the cruise set at 70 mph. Not once did I drive the car in an aggressive manner and my speed never dropped below 60 for the entire 10 mile drive. The engine temperature climbed to and hovered between 205 and 212 degrees the whole time. This was not the first time its gotten hot as its been regularly staying between 210 to 220 degrees during city driving with outdoor temps in the upper 50's. These temps have been my norm since just before Thanksgiving when, I had my oil changed at a local quick lube joint, which leads me to my first question. If they had opened the plastic coolant reservoir while the engine was at or near operating temp, would this have caused the system to take in air and develop an air pocket(s)? I have read where air in the coolant system can cause this exact problem and since it started on my thanksgiving road trip, immediately following my visit to this shop it lead me to this conclusion. I have since gone back to the quick lube place in question and they assured me that they check and service these types of cooling systems all the time and have never had this problem develop. They said they couldn't see how air would have gotten into the system from merely opening that overflow reservoir.
My knock story:
My knock story begins somewhere in early july when I found the procedure for the waste gate rod mod. I did the mod, drove the car for about an hour, made a few full throttle pulls, and then adjusted it back to stock after reading that the computer would probably adjust it out anyway. Now I'm still not sure that's exactly when the pinging started but, I read somewhere on here where someone was able to attribute that to their ping/knock issue. Although I am fuzzy on the exact date when my issue started it seems like it was right around the time I did that mod. I can't be sure that was what caused it as I have read and found other potential issues.
Now just to clarify the only time it pings/knocks is under what seems to be high load, abrupt (not no lift) shifts to third and fourth gears. The rpms have been as low as 3500 and as high as the redline when it occurs. Of course the higher the rpm the worse it seems to be. If I granny shift, pause very very briefly to let the rpm drop a bit between shifts and then release the clutch and get back hard in it, it doesn't happen.
One problem I recently found is that the plastic nipple in the turbo air inlet pipe that normally snaps off, had snapped off and the inline one way valve was stuck. I have no idea how long its been broke as I can count on one hand how many times Ive had the hood up since Ive owned her. When I saw that I thought, there's my problem, unmetered air getting into the system causing a lean condition. After fixing it the problem did seem to be less severe but, when I had the inlet pipe off I had noticed that their was a little puddle of oil that had pooled on the inlet of the turbo itself.
This leads me to the next piece of the puzzle. I had read somewhere that with more boost comes more blow by and that oil puddling like I'm having is normal with the high boost pressures you experience with a tuned car. Well before I removed the inlet pipe to fix the nipple I had been seeing boost pressures in the 20 to 23 lb range with the Trifecta tune so, I'm assuming I don't have anything out of the ordinary goin on. The car runs fine and doesn't blow any excess smoke or seem to use a lot of oil. I guess the question here is...Has anyone had the same or similar problem with the oil pooling and did it contribute to or was it the cause of their ping/knock problem? Did the ping/knock problem clear up when you addressed the issue? How did you fix the oil issue? I've been considering a catch can.
I know this is a long post but, if you've made it this far thank you and thanx for any input you can give.
