I doubt, even adjusted for inflation, that the air cooled motors were worth $20,000 or whatever a 996 crate motor goes for now a days. I'm fairly sure a full rebuild by your shop is 5 figures as well. So comparing the relatively simple flat 6 air cooled power plant replacement or rebuild isn't realistic IMHO.

Porsche aircooled engines have always been more expensive to work with than an M96.

No one that places a monetary value on these cars will reconstruct the engine, only those who love the car.

I have 30 of those people in my queue now. Porsche engines have cost more than the car is worth since the 356 days. Hell I was installing 10K engines in 914s 20 years ago when the car wasn't worth 2500 bucks!

I have thought more than once about dropping an LS into the 996 and selling the Porsche engine to offset some of the cost...mmm....

That said, if I ever do get a 996, it will be with the IMS upgrade already done before any metal debris was found. That's how we bought the Boxster. If the engine ever goes, I'm calling these guys:

Just bought a good core engine from someone yesterday who had installed an LS engine. He's having all sorts of weird computer issues and the windows won't operate and after driving for 30 minutes the car electrically shuts down.

Conversion complications are something we hear about all the time. Some people work through them, others give up.

Heh - those electrical problems remind me of the gray-market Jag we had when I was a kid. That car was insane...the driver window would come down if you used the cigarette lighter while the door was open, and it at fuses like candy, and those fuses with the element exposed were not cheap.

You just have to wrap those fuses in tin foil.. That solves ALL the problems!

Heh. I confess to using wood screws a time or two when fuses were scarce.

A quarter is also a perfect fit for those fuses. Burnt the dash harness on a Renault 5 because of it.

This. I bought my car knowing I WILL have to do the bearing and may well have to buy a crate motor. I intend to keep this particular car for a long time.

Others may have a different plan. Fine. Not for me to judge.

Good luck, OP.

The previous owner of my old '88 Carrera had the motor rebuild in 2002 for $16k. You'd be lucky to get one rebuilt for that amount today.

My '87 Carrera was smoking like a Mack truck by 2003 and I did a $6k valve job. As I remember, a full rebuild would have been about $12k but it could have been more (I didn't consider it since the bottom end was in good shape). Close enough to the prices mentioned here to be about equal.

BTW I don't look at what a car is worth on the market in making these decisions. Under a purely market value framework, it seems that almost any non-warranty service should be avoided. What I compare against is a replacement cost, where replacement isn't just similar model, year, etc., but also a similar level of confidence that it doesn't have hidden problems that have already been exposed/eliminated in the current one. This rebuild (repair) largely eliminates the single biggest hidden problem in this model. The question I ask myself is given what I have, what's my best strategy for minimizing total cost of ownership for the next 10-15 years (and, for these cars, maximizing enjoyment as well)? The longer I own the car, the more I know about it, and the bigger the difference between market value and value to me. I would expect that the guy who bought my '87 should be driving it happily for 50k-100k miles without major issue (http://blue-carrera.com). That car sold in one week with two bidders near asking price and after a dealership PPI.

You're making the right call. These cars are worth it.

We can all talk about it for many pages more and analyze it to death but what's done is done. OP took action based on his criteria's and comfort level and we all know it's in good hands now.

OP please update us on what is ultimately diagnosed. We are all wishing you the best outcome based on circumstances.
