Did you read anything? No fix until at least January.

I haven't read anything on this forum about anyone who has had a valve spring fail and had to have it (them) replaced.

I have no idea of how the manufactures found out they had a problem -

Good thing you're not in charge.

OK, smarty old pants, tell me how they discovered that the valve springs were defective -

It's scientific. You wouldn't understand.

In other words - you don't know ? -

It really puzzles me as to why we (the forum members and owners of FR-S and Brz cars) were caught surprised by this large recall, since very few of us had experienced valve spring failures.

Please do enlighten me - oh, wise one -

The reports said that there have been 94 reported failures across all the affected models. There were two that spoke up here (well three but the one guy was full of shit). There were probably enough that they went back and looked at the parts. Obviously they found something in the metallurgy or design that worried them enough to look through the records to find what lots were involved and from there it is easy to tell what cars they went into.
We get rotors returned from time to time to test and identify what caused them to fail prematurely. Our engineers and quality people can find out exactly what went wrong with surprising ease. The level of record keeping is beyond belief so if it was something that could affect a whole lot we could pretty much narrow it down to what day and even shift the parts were used on at the assembly plant. The parts that go into cars are more tightly controlled than most people would ever understand but as in this case some bad ones still slip through.

Something about pharmacokinetics, IIRC.

Thanks for the info -

So, 94 reported failures across all models. I wonder how many cars we are talking about? Only 2 reported failures among our forum group who many hammer on their cars (I wonder how many that may be?)

So, even though my car is on the recall list, I wonder what the probability would be of a valve spring failure, if I were to pass on the recall?

There are 400,000 cars involved in the recall. The cars are all 5 to 6 years old. There have been 94 known failures but let's say that there were 10 times that many that were never recognized as part of the issue. I will leave the calculation of the odds of failure to somebody else but I think the likelihood of one individual car having a problem is remote. I know that if I was involved I would probably just pass and take my chances.

I think I said something similar earlier. I'll likely have the engine apart for some other reason. Might consider it then.

What I'm afraid of is the toyotechs with a giant huge kawk gun.
They don't know what they've got a holt of.

Never had an engine held together with glue before.
Could be innerestin.

Ya, right now, I'm thinking along the lines of passing. I've only put 25,000 gentle miles on my FR-S in 5 years. So far, it has run real good and the engine is tight. In light of the 400 to 1 odds, I'm reluctant to have them crack that engine open.-
