Engine rebuild

[968er]

Now being back in the market for another 993 much sooner than I expected and also with a substaintially reduced budget due to my insurers I was wondering if there is any knowledge with regard to top end rebuilds on cars that have done 90K and over.

There is plenty of information on the 964 engine top end rebuilds at anything over 75K, but I have not come across anything on the 993. Even the article in 911 & Porsche world about the two high milers makes no mention of this. Have Porsche sorted out this wear problem or is this still something to rear its ugly head?

Look forward to your replies.

I would be very interested too in that answer and mine had done 90k already !

I had the top end rebuilt on mine after about 125k miles. The engine was leaking oil from the rockers and seals and as I was having a lot of work done to the car anyway I decided to go the whole hog. The incremental cost at that point seemed almost incidental... It really wasn't, though.

To be fair, the indy I used recommended doing the rockers and advised about the other leaks, but was rather surprised when I said go ahead and fix everything. I think most people just live with the (what are relatively) small leaks if they have them - we all check our oil levels regularly, right?! Many owners are running much higher mileage engines that have never been opened.

Still, at least my garage floor stays drip free now. Doesn't entirely make up for the lighter wallet though and I'm not sure I'd do the same again! If I ever sell this car someone is getting a bargain, that's for sure, as none of this stuff really adds value.

I'd say there's always got be some value in the fact that it's been done.
People shy away from higher mileage cars, but with a recent "˜sorting' of the engine, that might allay their (usually unfounded) trepidation on that subject, at least.

To be sympathetically driven and serviced/cared for regularly are best for our cars[] (not sat in the garage for months on end).

Thanks John thats really helpful. Excuse my ignorance but when one refers to a top end rebuild what does that actually mean?
Thanks

Dear John,
My car has a slight weep from the right hand side cam cover gasket. I would be interested to learn the costs you incurred for this to be replaced on your car? Did they drop the engine?
Kind regards
Robert

Robert, all four cam covers and or gaskets can be replaces without removal of the engine or indeed much other ancillary items. each cam cover is a 3/4 to 1 1/2 hours job depending on if some of the bolts are rounded,corroded or very tight and the upper covers are less likely to leak even if the gaskets are old ,but take longer to do due to less room around the fixing bolts.
