Somehow I get the feeling "Robert" is the service manager at Lees Summit Subaru. The same guy who thinks a thick carbon buildup on top of the pistons of a high-output turbocharged engine in less than 2k miles is normal.
He claims I autocross the car. I do not. I drive it on big tracks. I don't drag-race the car and I never use full throttle in 1st or 2nd gear.
Autocross is racing, granted. It's a timed event that is to road-racing what ping-pong is to tennis. Same thing but on a much smaller scale. Though road-racing is also wheel to wheel, which autocross isn't.
What I do with this and the previous 3 Subarus I've owned is neither road-racing or autocross. Previous 3 Subarus that didn't have these kinds of problems, I should add. If it were as simple as Robert wants to believe and that it's drive the car a certain way and it will break, why this one and not the previous 3?
I want to also mention again that Subaru themselves tell you not only how you should maintain the STi when using it for track days or autocross, but where to set certain controls in the car. I repeat, they tell you in the owner's manual to set the center diff on manual control and max rear bias when using it for a track day.
Robert is of the opinion that track days and driving schools are racing but Subaru is not of that opinion. Robert also seems to think that track days and autocross are the same thing. They aren't. Actually, I would think that autocross would be more taxing on the car than road-course use in some ways, but probably easier on it in other ways. You won't be doing 125 mph on straights in autocross, but you also won't floor it in 2nd gear on a road course.
I can tell when a student of mine who also does autocross is using an autocross approach to the track. They understand the analysis of turns and how best to get through them, but they're abrupt in inputs. So I tell them that autocross is a mosh pit but the road course is a ballet. Smooth on everything.
The only thing that makes me think maybe "Robert" isn't the service manager at Lees Summit is that "Robert" is focusing on trying to define my use of the car as racing and cause for lack of warranty coverage, where the Robert at the dealership isn't making my use of the car an issue at all but instead maintains that I neglected the car and let it run out of oil.
When I took the car to Lees Summit a few months ago (prior to the second engine breaking the same as the first) because the Chuck Engine light was on, the service manager noticed the Cobb AP controller in the passenger seat and, I swear to god, GLEEFULLY told me I no longer have drivetrain coverage because of it.
I've used Stage 1 tuning a time or two and Valet tuning and even found that if you set it and an iPod in the same cupholder, you can inadvertently find yourself in anti-theft mode, as that's the default you're gonna get on, I think, 3 taps of the center button. Imagine the fun of learning that one very late at night out in the sticks.
Anyway, it turned out the CEL was thrown because a fuse in a fusebox I didn't find in the car or manual (under the glove box) had blown. Actually took the mechanic a while to find it.
But I digress a bit. Robert at Lees Summit said the Cobb was a straight-up warranty-killer. According to him it doesn't even have to have been used to reflash the ECU with a safer tune. It simply being in the car is all it takes. I used it for a Stage 1 91 Octane flash up until Subaru did the recall that isn't a recall and admitted they had software problems and reflashed all of the STi's. Since then, I've left it on Subaru's tune, which, while less powerful, feels more conservative so should've helped engine life, I'd have thought.
The Cobb controller is also an OBD reader. I used it to determine that the CEL was complaining about the heaters for the O2 sensors and decided that wasn't something that would endanger the car on the 46 mile drive to the dealership.
Robert disagreed. His position is that if you get a CEL, you don't check the engine. Even if you're a former professional mechanic and happen to have a friggin' reader. Instead, you drive it to the dealership.
Yeah, right. What if I hadn't read the codes and the CEL was for something more dangerous to the car like, say, no oil pressure.
We had quite the loud, vulgarity-laden argument on that visit. I'm really tired of his adversarial handling of me when I've been such a loyal and visible proponent of the marque for so long. Heck, I traded in my low-miles 06 STi on an 07 the instant it came out so I could get the taller middle gears and not hit the rev limiter anymore in a particular turn. And kept the 07 for a while after getting the 08 so I could compare the two versions of the car.
Anyway, Subaru did reimburse me as a goodwill gesture on the first engine, but I think primarily because I'd bought 5 new Suibarus in 3 years. I'd mentioned that as an aside to the rep on the phone and her tone changed and she said when I write, I need to emphasize that.
But I want to get back to the issue of "neglect" which is what the dealership cited on the first engine and which I put a lot of effort into dispelling in my letter to SOA.
Guys, I have my own freakin' lift, tire changer, and a large supply of expendables such as oil, gear oil, trans fluid, oil filters, and the like for not only each of my track cars, but each of my cars period. I don't mess around when it comes to this kind of stuff. I don't buy 1 oil filter and 5 quarts of oil. I buy 6 filters or however many the store has on hand, and my oil is bought in cases though I'm seriously considering going to 55 gallon drums with air-power pumps at least for the viscocities I got through a bunch of.
My garage is 7200 square feet, my tool cabinet a massive Snap-On, with the same name on most of my tools, and, again, a freakin' lift! Not really the trappings of someone who ignores and neglects cars. You don't get a lift because you like seeing cars go up and down. You do it because you service your cars so frequently it's worth the money to be able to stand and change your oil rather than use ramps and a creeper. And you don't use Motul 600, at $14 a pint, as your frequently replaced brake fluid if you don't take your car and its condition and upkeep pretty seriously. And you don't get your own tire changer, and the UPS man doesn't get to know you so well that when he's got yet another bunch of tires from Tire Rack for you, he throws them in the back of your truck at the office if he's going by. And the people at Porterfield don't get to know your voice and go to the trouble of making sure they have a rough idea what you're going to need from them soon and make sure they have it in stock.
Anyway, dealership said "neglect", Robert here claims "abuse", but he also claims track days and autocross are synonymous, so I have a pretty good idea the value of his opinion, and Subaru themselves are being kinda quiet on the issue. They're replacing engines left and right because of broken ringlands. Even replacement engines are being replaced, but sometimes a b*tthole dealership does try to intervene and blame the customer for the pistons that're simply too fragile for the increased power and tighter emissions limits. I've got a broken ringland in my replacement engine, which is producing 140 psi compression on 3 cylinders and 75 psi on the culprit one.
And under controlled conditions, I've determined that my engine can now consume all of its oil in just under 10 minutes of very hard driving, only puffing smoke occasionally, and running more strongly because of the higher BTU of oil versus gasoline. No, I didn't run it out. I drove it on a circle track (no other cars were present) for different lengths of time, measuring my oil level on the dipstick with a micrometer, refilling, and repeating until I was able to determine an oil consumption rate of just over a pint per minute under heavy use conditions.
This was a neighbor's small practice track (yes, I'm *that* country) in his yard and I ran it in 3rd gear reaching a maximum of 67 mph. The logged data showed I was full throttle 78% of each lap and never got very close to redline.
One last thing. I noticed that in my original post, I didn't mention (maybe I didn't notice yet), that one of the camshaft sprockets had been installed incorrectly at the factory. The appropriate machined hole was not over the locating pin on the camshaft as it should've been. It had been forced on, making a new hole in the process, several degrees away from where it should've been, which very well might've been why my first engine started acting the fool as soon as it finally saw 5200 rpm.
Dealership service manager claimed that the camshaft had seized and caused this sprocket (and only this one, mind you) to tear itself out of position. Despite all the camshafts and their wear surfaces in the heads being in pristine condition. They don't use bearings but, instead, machined surfaces for them in the heads. Nothing wrong with that, as it's been common in Japanese engines as long as I can remember. But when you get seizure in that type of setup, it is VERY obvious. Aluminum makes it pretty clear if a spinning piece of steel made oil-free contact with it.
