Stock Motor is Toast (Spun Rod Bearing) - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

DFW-FRS · 01-19-2015, 09:44 PM

I've had my FRS since July of 2013 and after 25,000 miles the rods started knocking and we discovered a spun rod bearing. The Toyota dealership said "they've never seen anything like it" lol. Anyways, they agreed to replace my entire short block for free, updated my ECU, and put me in a 2015 Corolla S, which must have stood for "shit" because that thing has no business being called sporty. Not sure how I feel about my FRS now, but I've already broken in the new block with about 1,500 miles. If I wanted to blow up a boxer engine I would have gotten a WRX, but I digress.

So does the warranty on the motor now go for another 36k or does it still end when the car hits 36?

Not much experience w/ 'rods knocking'.. what would you say your symptoms were or what to look for? I push my car pretty hard occasionally with oft e85 tune. Just want to make sure I know what to look for.

WTF...
that's not right
replacement part should have another guaranteed warranty again.

Drive train goes to 60K. 32K is bumper to bumper.

Let me just say if you had problems, you'd hear it.

There's nothing to "look for," it just starts happening when the bearing tolerances become larger due to oil starvation mostly. All that extra space between the con rod and crank will cause a metal clanking sound and will get louder and faster with more engine rpm.

That, or just a fluke at the factory.

If it were my car I'd be looking to trade it.

What caused the failure ?

FirestormFRS · 01-20-2015, 08:54 PM

Bottom ends don't fail easily. They're pretty much bullet proof at stock levels unless they are starved for oil.

That's what I'm trtrying to figure out also....

They took my motor apart and crank case turned blue do to lack of lubrication and oil starvation.. my car had good oil level also.. no check engine lights btw..
32999..

Did any of you have a Cam issue/CEL before the engine failure?

I was in fourth gear doing about 50 MPH when I downshifted, accelerated, and heard a strange rotating rattling noise coming from the engine bay. I turned down my radio and the rattling turned into loud violent knocking. The car died in motion and I lost power to everything. Luckily it was on an empty Texas highway.

This man speaks the truth.

It's a lease so I'm not worried about it. I do worry that it will happen again though.

Car was somehow starved for oil and spun a rod bearing. The techs blamed it on my old 2012 factory tune. Apparently there was an ECU update that I never received.

True.

None at all. I've only had ignition coil failure in two cylinders prior to this.
