My apologies--that is the post I was thinking of and I mistakenly attributed it to you.

I'm still curious about how the over revs impact the decision especially with the 996's. There's no way to know how high the revs went. Are any over revs disqualifying?

The old IMSB looks like a dual row?

Gentlemen -

Please cease the personal stuff.

Thank you.

No answers?

I will not attempt to answer the question about disqualifying the engine for the Solution.
However, the implication of type 2 and greater over revs, is that this is usually as a result of a mechanical over rev. This can cause a number of problems: from stretched chains, to piston to valve contact.
I'm sure those with more experience, in this area, should be able provide more and better detail.

Thanks Scott. A friend is looking at 997's so depending on the year, he may get a car with the IMS. He's owned other P cars, a 993 and a 996. I agree with most folks that the solution is really the best option for replacing the IMS. Since most PPI's include a DME report, we're thinking of asking the mechanic to just go ahead and do that first. If the rev report is disqualifying, we could end the PPI right there and move on.

EDIT - And I guess if a bad rev report is disqualifying for the IMS solution, it's a car he shouldn't be buying anyway.

Wheeler Dealer is a television program whose intent is to appeal to a broad audience, not just 996 fanatics. I have been watching the show for many years, even before it ever aired in North America. At first I was not a big fan of Ant. He is actually pretty good. What I do miss is that the earlier episodes got into a lot more detail of what was being done to the cars. In one episode, Mike uses a deck of cards to cover a tire to paint the rim. This was a very useful cheat!

Yes, a lot of steps were missed on air for the IMS Solution install.

So what? It was fun without the ridiculous drama of a lot of other auto shows.

While you don't know technically how long the car was in an over-rev situation, you have plenty of data to know how long it _could_ have been. My car had 25 range 2 ignitions when I checked prior to purchase. At the rate of 3 ignitions per revolution @7k RPM, round down, and you get... 300ish ignitions per second. 25 goes into 300 12 times...if all 25 range 2 ignitions for my car happened in the same incident, the longest period it could have been running at that speed is about 1/12th of a second. Since I also knew that the last Range 2 ignition happened many operating hours ago, I felt that there was negligible exposure for this particular concern.

well, 1/12 of a second may seem a short time, but in my experience recorded over-revs are typically that short - something else happens to slow things down immediately; clutch/wheels/ground. more telling is the time elapsed since the over-rev; did it just happen or has the motor been running happily for hundreds of hours since?

The range-2 ignitions I've seen happen in real life are almost always due to money shifts at the track. For a car I don't know anything about, that's what I want to look for recent evidence of - some clown who doesn't know how to drive it hooning around and yanking it down into the wrong gear. If you can't get 0 range 2 ignitions, a small number that hasn't increased in a really long time trumps (er, is better than) a giant number that recently got even biggerer.

The engine isn't meant to spin beyond a given speed...but safety margins exist for every part in an assembly to allow for metallurgical flaws, finishing issues, production variance, etc. My hope was that the Range 2 ignitions happened so long ago that any failure introduced or weakness exacerbated would have long since presented itself. Thankfully, that's been the case thus far.

Decent episode. Replaced IMS with LN Solution. Did a few other minor fixes and upgrades. Paid $16k then sold for I think $22,500. Reasonable money for a MY2000 C2 Cabriolet.

I was thinking the same thing. MIKE said engine was broken but I think he meant the IMS had not been replaced. When they removed it they mentioned it felt gritty. No inspection for metal bits so as we all know even with the IMS Solution that motor could grenade somewhere down the road.

It's a TV show, they can't show you every step they took...Lots of editing to make it all fit into their time slot.
