What should I do to the engine while it's out?

If your flywheel is original, just plan to do it. Of course, RMS too. At 105k I’d probably opt for the Pelican, or even Porsche IMS. Technically, I don’t think your engine would “qualify” for the “solution”. Tensioners for sure, you are right there anyway, possibly pads. Might be worthwhile. Coolant bottle maybe? How is your trans? Any second gear issues? If so, might want to think about that too. Might not be fun, but you will learn a lot and it will be rewarding once you get it all dialed.

What's the issue with second gear? These cars have so many "known" issues I can't even keep track. This is a new one to add to the list. Can you please explain what's up with second gear? I have no issue with it that I'm aware of.

Some cars pop out of second gear and there is an aftermarket detent available to make the gear engage more and no longer pop out. If your car isn't popping out of second gear you don't have the issue.

The motor mount of course. When I did my engine, the trans mounts seemed fine. While it's out, spark plugs, coils, renew and regrease the half shaft boots--clean the grease out of the cv joints and pack with the grease that comes with the new boots.

New hoses as needed--I had to replace 4 way hose (tiptronic) and replace the little hoses that connect the coolant bottle manifold that goes thru the rear firewall to the small metal tubes that run next to the engine on the passenger side.

While you've got it all apart, maybe an underdrive pulley, certainly a new fuel filter. And I put a spin on oil filter converter and am now using cannister filters. A magnetic drain plug, too.

While you have it up on a bench or a motor stand, I'd pull off the sump and really give it a thorough cleaning and inspection.

You are a braver soul than most of us to be pulling a head off for recon. I bought a different engine to avoid doing that.:chicken:

Keep us in the loop, and take pics. Good luck!

Coolant reservoir. I didn't do mine when the engine was out and now every time I walk past the trunk a hear a quiet "tick tock" from within. In fact I'm twelve miles away from the car and I can hear it from here.

Vacuums lines, reseal the oil pan and clean oil pickup line and replaced o-rings. Replace AOS plastic lines and associated o-rings, at this mileage they are all brittle.

Lastly, clean your radiators this is why you have a crack head. Separate the condenser and water cooling radiators and clean the fins. DO NOT use pressure washer, spray water directly and perpendicular to the Radiator, faucet pressure should be good enough.

Did you check if your water line rubber hoses are not oil damage?

Good luck

As mentioned the second gear pop out... fairly common. Also, second gear synchros start to die, see first issue, and then you get second gear grinding while trying to shift. If you are not experiencing this, not to worry. But do your tranny fluid with Porsche blood of you haven’t already.
