It will cost you like a grand out the door, if they want tou charge more go to other place. I was there mate

I reckon ol @guybo had a "brain fart" when he typed that reference in his post ...... :D

Question ...... will a dealer replace a TOB under warranty, if it ain't broke ...... :iono: ........ but I doubt it .....??

In my experience with stealerships, they will try and pass it off as a wear-and-tear item and try and do everything in their power not to replace it even if you're under 36k, much less 60k.

I soon exceeded 60k after my poor experience with dealerships and got a buddy's shop to install an ACT clutch while taking care of the TOB issue. Not a free fix, but I didn't want the TOB to strand me.

But at stock, the oil temp still gets up to 215-230 normal working temp doesn't it? Just because the thermostat opens at 180 doesn't mean that the oil temp stays 180. The car is designed to let the oil temp get well above boiling for this very reason I mentioned ;-)

It sounds like some people have had success if the clutch pedal squeak is obvious when the dealer inspects it. Mine only squeaks and groans when it's super hot outside and I've been driving the car for a long period of time. I'm sure it will get worse over time though...

I had mine replaced under warranty back in April. Not a thing wrong with the first one, I just happened to bring up the TSB to my adviser at the time and he was on board with having the revised part installed to avoid future issues. He said in addition to the BRZ, it's fairly common with the newer WRXs, as well.

Since ol @Ultramaroon is off to work (to contribute to SS, so as my SS checks (which I paid into for 50 years) will keep coming), I will respond for him.

I think what he is ah picken on is your statement:

"The oil has to regularly run well over 212F to burn off water in the crankcase from normal condensation".

I too, consider that statement somewhat misleading.

For example, the last time I judged a wet T shirt contest, water was evaporating off of the wet T-shirts the girls were wearing ....... I'll admit those tits were HOT ...... but I doubt they were 212 degrees F or over ...... :eyebulge:


;)


humfrz - another HOT, smoky day in Puyallup ......:sigh:

The 86 is designed to run on E15 reliably.

As for a reliability mods-

Unless you are going FI, don't install an oil cooler. The oil has to regularly run well over 212F to burn off water in the crankcase from normal condensation. An engine that does not run hot enough is going to have reliability issues.

Install an oil catch can. It's good for the long term health of the engine by preventing deposits from building up on the valves.
E10. Many manufacturers, including Toyota, Subaru, and all the Japanese ones pointedly repeatedly state never to put more than e10 in their vehicles. Heck it is even in the owners manual.

Also e10 gets worse gas mileage, sometimes by quite a bit.

But it really isn't a big deal as long as it is just e10.

The engine and oil can tolerate excursions above boiling. I draw the line at calling it a requirement. LOTS of conflicting opinion out there but I've never found any official anything to support the argument either way.

Toyota/Subaru set 80* C (176* F) as the standard temp for oil pressure test. That's good enough for me.

sorry to kind of hijack the thread a bit but does anyone know if the TOB issue is still on the 2017s?

The TSB States 13 to 16s but it was issued in April 17 so yours could be covered if it was an early 17 built in late 16. Usually they give a VIN range but this one just says years.

My crickets love E10. Since I don't like crickets I use ethanol free. Ethanol free doesn't make much difference for me in gas mileage. But I am comparing 91 octane ethanol free with 93 octane ethanol gas. I will fill with 93 octane again next time to see how the crickets are doing and check the gas mileage. There is also air temperature. The car hates hot and humid air; power and mileage suffer miserably with such weather. I gotta find a nice week to test 93 ethanol gas.
