Addo said:I had the same issue on my fathers 996 turbo, although the hole was larger than that. The hardest job is removing the turbo and oil line from the block.
I sent it to AET turbo's (01924 894171) to be rebuilt as they have spares for most turbo's. They offered an exchange for £685 +vat leading 1-2 days or rebuild your own £250 + vat (depending on parts) and 2-3 days, both came with 2 year warranty. Porsche oil lines are about £90 each, i was very happy with the service so would advise speaking with them.
Already done with stainless steel. Will swap themMezgerite said:Pull all the exhaust nuts and bolts and replace with titanium.
A thread would be great on engine removal.darkhorse said:Update on this. Can't get the water pipes off the turbos in the car, so going to remove the engine and box at some point in the next week or two and remove all pipes with it out, and replace the ones that need it (if I cant still get them off the turbos).
Bit of a pain to be honest but gives me a chance to attend to anything else while the engine is out and of course get my first tick on the scoreboard of 997t engine removal/refit. If it would be of use to others I can take some pictures and do a thread on the job, seeing as there is very little on mezger engine removal that I can find online.
Anything else crucial that I should replace while the engine is out?
Im going to go through it all closely. Potentially will pin the coolant pipes depending on if they look new or not as the car has had plenty replaced over the years from looking at it.
I was thinking about replacing the exhaust manifold bolts while its out, but I have read about the nightmare these can be and the manifolds are not leaking at all. Will see how that goes. Some of the bolts heads are corroded quite heavily. I read somewhere that 997t bolts come out better than 996 studs. I cant see that being the case though it doesnt sit well with me not doing them while the engine is in front of me..!
Cheers

I replaced my manifold bolts with titanium, and luckily for me, the old bolts wound straight out. It probably helped that I had sprayed them daily for a couple of weeks prior to tackling. TheFinn had issues on his Carrera and ended up buying a Stomski jig to drill out a few sheared bolts. It may be that the Mezger unit bolts wind out easier generally?

Ishay said:Has supply of the VVT turbos become easier again? A year ago they were on back order and mine was bought from Greece!
The other turbo is going to need doing eventually, although it hasn't seen rain since. I think one of the indies was selling refurbished ones but I can't recall who
easternjets said:The manifold bolts are not the same on a Turbo as they are on the non turbo cars. I fretted over this when I was doing mine and then when I actually went to take them out they all came out very easily.
They are not studs and nuts like the std cars, they are literally a big bolt!
Coolant pipes are obviously the main item that should be replaced. What corrodes on the fittings is the Aluminium cup, it seems to get chocked with a type of residue from the coolant, it then gets behind the alloy fitting, expands and cracks the alloy and a leak starts.
I've seen people change the whole system, flow and return. If your keeping the car for a long time then I suppose this is a belt and braces thing to do but I just changed all the rubber pipes with new ones and cleaned everything out, then sold the car.
