M96 3.6 Motor Blown
#16
Now I'm about 800 miles with my new engine and still in the process of breaking it in. I've heard conflicting input regarding when to stop babying the engine, rev levels and so on so I'm not entirely sure how I should continue. Although I do have to say that I'm finding it difficult to stay below 4200 rpms!!!
Talk to the dealer and see what can be done. I'm TRULY feeling for you and do pray that this situation will resolve itself for the best ASAP.
Keep us informed!
I too had a complete failure around 4 months ago while tracking my car, same thing oil pressure and then boom, http://www.youtube.com/watch?v=qZqgyVpSuxc and no we didn't plan on it that day, it just happened we were doing some filming.
I had a new engine put in the car and was on the track again the following weekend. There is no baby in time for a new engine, only transmission
Cheers

Sorry to hear about your engine...
I also had a complete engine failure on the track, in my case it was an intermix issue, and the engine went BOOM with a huge cloud of grey white smoke. All the idiot lights came on and the engine was finished. After i got over the intial shock, i promptly ordered a new motor, and was back driving 2 weeks later. Yes it was expensive, but a porsche without an engine is nothing....
The longer you think about it the worse it gets, its unfortunate but you need to turn the page...
good luck

These failures are likely to continue. This is exactly why I sold a 996 3 months after I bought it and bought a 993. The 993 has twice the miles on it but I don,t feel the need for an extended warranty and don,t cross my fingers and toes every time I start it.

Reman Engine
My concern with Porsche remanufactured engine is that it will come with all the same problems again. Apparently they just use the same original parts from that year. You only get a 24K mile 2 yr warranty.
Any opinions on some of the rebuild specialists out there on the internet space?

Doug, I was about to quote the same thing of an engine rebuild on a 993 being twice as much as replacing a 996 engine... Talking to my mechanic 993 are not bullit-proof either,,,,
It comes down to understanding ownership costs of older Porsche's

Why would you be breaking in the engine, all the engines that porsche build are completely broken in at the factory. The reason they tell you to keep the new car under 4200 rpm is to break in the transmission.

Being a retired licensed mechanic in Ontario, with lots of 911 experience I am aware the 993 engine is not indestructable and can be very costly to rebuild. They seldom fail in a fashion which renders them unrebuildable though. Back in the 70s I often saw cars drive in with the cam chains slapping because of failed tensioners but they were often repaired without removing the engine.They will also run with several broken studs. Notice Porsche still uses the air cooled bottom end as a basis for the turbo motors not the m96. Porsche improved all their engines over time but things like improved chain tensioners , better cylinder/head studs and stronger/long life cam belts can be easily backdated into earlier engines. The m96 has been no doubt improved over it,s production run also so IMS bearings are better and intermix from head cracks and cyl slip are less frequent. It appears though that these updates are only available by replacing the complete motor and the cost of that has more than doubled in the last year or so. Too bad Porsche has chosen not to support these engines the way they used to. They appear to have built a timebomb engine with a fuse of unknown length which may or may not outlast the rest of the car.When or if it fails it gives little warning.The engine is the heart of the car and this heart disease is at the root of the 996s fairly rapid depreciation.

Actually the 996 depreciation at this point in time compares rather favorably to other cars, and most previous Porsches, with the exception of the 993 -I think that's mostly due to the nostalgia attached to "the last air cooled Porsche" than anything else, but hey that's just one more opinion.

I'm not up to snuff on the cost of re-manufactured 996 engines from Porsche, but if the gentleman's cost, above, of around $8K is indicative of current pricing, that's about what a quality 993 top end should cost. A "complete" rebuild (bottom end) is rarely necessary unless catastrophic engine failure has occurred - in which case costs get out of control very quickly. As in all cases, the cost of labor is the killer.

I think 3.4's remans are up to $14K-$16K. The 3.6 is significantly less, more in the $8K-$12K range. And Jake Raby can do a 4.0 build out of a M96 for abut $21K. All of which is still a lot less than a total rebuild of a 993 engine.
