Pulled the engine and gearbox out over the weekend there.
Engine is now sitting waiting for its stand to show then I'll strip the heat exchangers just leaving a bare block to drop off on the 29th May for its top end overhaul.
It's broke a head stud but whilst it's in bits I'll get the whole 24 replaced, new set of rings and get the heads overhauled.
Happy days and looking for to seeing the thing spit out flames again!

It always looks so painfully expensive to see a set of delavar (sp?) studs sellotaped together waiting to go in a rebuild and knowing that they cost £500 eek

Still, enjoy it when you get it back. driving

Pulled the engine without any problems:-



Once up on the stand - it's an impressive piece of kit:-



Noticed a couple of the cylinder heads were passing:-



Once on the stand - and looking the thing over, I've decided it's not a too difficult job and I'll do it myself.
I've ordered the cam sprocket removal tool and once here I'll continue with the strip-down.
Interesting times ahead.
As for the head studs - I'm already planning a long weekend in the states with some new parts waiting for my arrival.
Cheers

I am in the middle of having my 911 85 rebuilt. The engine is done a ready to go back into the car.
I didnt worry too much about the headstuds and I completely did away with the heat exchangers to save weight...... but I now live in the tropics so I dont need heat.

I kept mine pretty standard, just got a decent Dansk exhaust system, steve wong chip, K&N airfilter, quality leads/ plugs etc , replaced all the tinwear and ceramic coated the interior of all the exhaust system.

hoping she will be putting out a bit more than before on the worn engine.

I contemplated the rebuild myself but when the gasket set arrived with over 200 of them I passed it onto a Porsche specialist. I am glad I did having watched him working on it- the guy is meticulous and spent nearly a week cleaning every part of the interior with a cotton wool bud........ i am not even joking

Wayne's book is quite good. I'm hoping to do the engine from my SC myself as it should be possible as a DIY job although I think there are lots of tricks of the trade to help get it right (and not have is piss oil out afterwards!).

It strikes me that one thing a pro will know is whether bits are ok to reuse or whether not to and to replace.

I'll post some photos tomorrow, cylinder heads, barrels, cam covers etc are all off and passing through the ultrasonic cleaner. Barrels are away being measured up (using lasers)!
Crankcases about to get split.
