Motor/turbo rebuild at 38k miles?
Found a car that has had a LOT of work done including motor and turbo rebuilds; has 38k miles on it. Is this typical or should I be running away screaming?

You have to dig deeper. Figure out the history and get a really good PPI/leak down/compression etc. If you like the car otherwise doing the diligence is worthwhile.

I will do some checking this week.
As far as I can tell with what records I’ve been sent,
the engine had exhaust valve lifter issues/replacement (but not a full rebuild) and had the turbos rebuilt. All the exhaust valve lifters were replaced.
It looks like a lot of work done but it appears that the owner was very **** about things working and keeping up with maintenance items so a lot of little things were done (seals, gaskets, filters, belts, O2 sensors replaced, etc).

You need to find out exactly what was done on the engine. Lifters is an in-car job and not even close to a rebuild. I suspect you mean valve guides. Not uncommon for this to be necessary on a low-mileage 993.

Ok, this engine had all 12 lifters replaced and misc maintenance and updates -- belts, filters, gaskets, plugs, heat shields, cleaned injectors, etc. Engine has not been rebuilt in any way. It looks like they installed rebuilt turbos. Look under "Engine Labor" and "Install Turbochargers" sections of the receipt. Sounds like good maintenance. Unless there's a story here this is the kind of work you want to see on a relatively old used 911.

There's a story here. 38K does NOT warrant this level of maintenance unless this car has been heavily tracked, abused- maybe a missed shift from 5 to 2 and blew a valve? Personally, I would need to have the car thoroughly inspected- not just the motor- but everything. Soaking a motor in a flood would warrant this kind of repair as well. Scary.

Exactly! There is nothing there that is even slightly out of the ordinary for any 993 (now 20+ years old) at this point in time. More than likely there was oil leaking/siphoning back into the turbos as result of someone trying to save $10USD with an OEM Mahle filter instead of the OE Porsche version. If a turbo is blowing oil then ya it will need some work and you might as well upgrade to Kevin's zero clearance versions... Lifter seals can/will deteriorate with mileage AND age.

Hey Churchill, Not trying to create a mess here- and no need to get all " take it down a notch"- did you see where the OP lives? Mississippi. Flood country- a few massive hurricanes the last few years have put a lot of cars on the auction block with salvage titles. That's the only reason I brought it up. When researching a 20 YO car that's had that much work- i'd question it. All of the work on that car could have easily have been due to it sitting in a foot of water for an extended period of time- that's all. Yes-could be seal rot as well- but if the Car Fax show consistent miles driven over the years, that's less likely.
I just pose an option to watch for - especially in that part of the country. That's all..

OK- Never mind, I am sure the car is perfect and totally legit. I just went off of your signature- you didn't mentioned where the car was located. Peace out.

No problem and thanks for all the concern and feedback! I have to say that the flood/water damage issue was first on my list of concerns. The car appears to be very well maintained and comes from a collection of about 20 cars. The seller is only selling due to GT2RS and GT3RS acquisitions and has several other 993's.
