Robert,
My pleasure, glad I could help. That tool is getting some miles under its belt!

Nice eye, I was wondering who was going to notice that first. That happened when I tried to use the exhaust tips bolts to hold the crank in place. I used an old BMW fan removal tool and placed 2 molts into the holes trying to hold the crank in place. Obviously, epic failure, but Andreas came through. No damage to the pulley.

Another for Curil T I like these products BTW nice post!

Thanks for taking the time to do this great write up.. After 6+ years of ownership, my cam chain timing covers have started to leak. Maybe with CarreraX's help, I can drop the engine and do a few other projects.

I would say go for it. I am in Louisville so only a short drive away to help out in any which way. Haven't dropped the entire engine, but I am sure it's not all that bad. Pick a good weekend and it will give me an excuse to go for a nice drive.

Cheers

Great write up as well. I referenced when doing my timing chain covers and other maintenance items last weekend.

One comment, you do not have to removal the crankshaft pulley in order to access the right sided timing chain cover bolts. Just unbolt the AC bracket and slide it forward to give clearance to remove that one bolt in top left corner of right timing chain cover.

I didn't reinstall the engine covers surrounding motor since my car is primarily track only and won't see snow/salt.

Robert, Thanks!! Need to figure out if the leak is from multiple locations or a single spot. Car is in storage currently. Will let you know if I drop the engine. Mark (CarreraX) has done a few clutch jobs and can drop one in his garage without a lift. Luckily I have a lift so that the access will be much easier.

I did this last year and as Xene said you don't need to remove the crank pulley. Some nice write ups here;- http://www.jackals-forge.com/lotus/993/chain%20guard%20covers/chaingaskets.htm
Though he did put the captive nuts fot the cat heat shiel on the wrong side.

Hi team,

need Ed some advice - have been following this - also doing upper and lower valve covers at the same time

i am at a still stand since there is one bolt in the engine compartment I cannot get loose holding the heat distribution box to the rear of the car

questiin - is it possible to get at some the engine pan stuff out of the way and lower the engine down a couple of inches anyway?

given I have to do that for the RHS TCG I was wondering if there may be a short cut

One of he two hidden Allen bolts that attach the crossover tube to the engine carrier? I've done this job on numerous 993s and had one where the bolts were seized. I carefully drilled them out from below and then used new Allen bolts once all of the old bolt threads were removed.

Thanks Andreas,

Yes those are the bolts - real bastards. Can you explain to me in a little more detail how you drilled it out from below - did you literally take a 4 or 5 mm bit and drill it through then remove the threads? And if that was the approach - next question is of course how to remove the threads

I have an extra long Allen socket just for those bolts.... after making sure I was as close to center as possible, I drilled the bolts from below with successively larger bits. At some point the drilling allowed the heads to twist off. Then the crossover pipe can drop. The remainder of the bolts then came using a propane torch and vise grips. You can also drill until you're within a whisper of the aluminum threads - at that point it's fairly easy to use dental pics, scribes, or fine-bladed screwdrivers to coax the threads out. Creativity is key.
