GT2

[fredt]

From what I've learnt, a leakdown test will not help much to show over rev issues (i'm certainly no expert and could be wrong)

The thing you might damage on over rev is camchain and valvetrain related, if you broke things enough to cause trouble on a leakdown test I cant see it running properly and making good power. And it's making good power allright


Yes, it's pissing me off 'a bit'

40 hrs

That's not too bad.

One independant dealer in the UK won't buy cars with less than 50 hours since the last RR2 activity.
Best way forward now is leakdown test and oil analysis. Just be aware neither are proof perfect it won't have issues, but at least you'll have done your due dilligence.

If the rest of the car stacks up (well) and the vendor is willing to compromise on his asking price, I'd proceed with (all be it caution)

Edit to add, if the camchain/tensioners etc had been compromised massively, they normally let go thereafter pretty quickly (ie less than 40 hours)

A leakdown test will tell you if the valves have got intimate with the piston crowns, so actually it is worthwhile doing IMO. I'd be asking the vendor to foot the bill for the checks .......

Ah to detect a slightly bent valve or something like that?

If you don't mind me asking, where's the car located ? (roughly)

[fredt]

Roughly Sweden

Why?

[W1TAK]

Is it possible to hear a worn camchain or valve tensioners? If yes ( because I am no expert ) would it show up with strange sounds when either cold or warm ? I remember somebody having a 12k gbp refresh by 911V due to something wrong in the engine on a 996 GT2, otherwise I never heard of anything going too wrong with these motors...

[unclepezza]

Agree RR1 no big deal as hitting the limiter on upshift, once the boost spools up easily done on the jump to light speed.

RR2 more of an issue though and 40 hours is quite recent, isn't there some guidance along the lines if over 100 hrs ago no issue as damage would if shown itself in that time frame.

Perhaps you can ask for leak down tests etc and have the same checks done Porsche do on a used car with over Rev activity at the garages expense.

Sorry it's not gone as smoothly as you had hoped.

[PHOENIXUK]

At what revs is RR2 logged?

[m33ufo]

If you have a remap it's possible that you're in RR2 during normal driving if the rev limiter was raised.

40 hours ago is actually quite a while! At an average of 30mph 1200 miles in fact.

Have you checked the total running hours against the total mileage?

This was the jist behind my question..... Does anyone know the revs that trigger RR1 and RR2...

Hi all just handed money to mark now have huffies gt2 will send photos presently car is heading on trailer from Bridgend to Clitheroe some crappy weather I've never seen the car sat in it etc I turned it down in May and now bought it
So no regrets first time I'll see the car is at Manchester Airport in April then I'm heading to the only place in UK that you can drive and enjoy good empty roads great surfaces etc north west coast of Scotland anybody fancy joining me I know the it like I know the back of my hand
And thank you all for convincing consul not to part with his mk 1wheels
I'm needing a set
Cheers Jim

No point raising the rev limit on a Turbo/GT2, as put crudely, you just whack up the boost and chuck some more fuel in.

The car which required the cam chains, guides, tensioners and intermediate shaft replacement was my old car. I sold it to 911V, they sold it to an Australian, who subsequently sold it back to them before selling it to Jason (Consul)
The camchain replacement had nothing to do with RR2 overrevs in that instance.

Fredt, I wasn't sure where the car was, had it been in the UK I could've advised on individuals to inspect it/carry out the engine tests.

With prices increasing has anyone updated insurance to cover this?

[fredt]

Well, decided I spent too much time looking at rev ranges and too little time buying cars.

Money sent, deal is done. Bring it on!

Hope you enjoy the car Jim. It's certainly the most enjoyable Porsche I've owned to date.

Not sure I'd have your willpower to wait until April!

Try Mr Huff on the Mk.1wheels, he still had them 3 or 4 months ago. He's not always easy to get hold of though - usually have to wait a month for a reply

Congrats.

The whole rev range BS is just a mechanism Porsche use to limit their exposure to warranty claims. I'm not aware of any other manufacturer who operate a similar system?

At least with 997 you get a more detailed indication of just how far over the limiter the car has ventured. The two ranges in the 996 are next to valueless.

[ArcticGT]

All Porsche had to do was add a recorder for the max rpm reached and it would've been much more useful.

Lotus also record max rpm and operating hours.
