My 2018 GTS with 40k is showing some seeping on the passenger side upper timing cover bolts. I have checked around and this is apparently a systemic problem with the aluminum bolts. My dealer tells me not a factory recall yet and I have heard about the possibility of a class action lawsuit. I hear the fix is to use bolts from a 964 but the engine needs to get dropped.
Anyone have and further info?

check the thread pinned on top, it's a $400-600 repair if you just replace the bolts affected, not a permanent fix but it'll reduce the oil leak to minimum level.

what is the permanent fix?

Drop the engine and do it right. Maybe $15,000. Porsche newer response. Replace two bolts. No engine drop. Cost is $750 Independent; $2,000 dealer.

You forgot $37.95 DIY…

What is the torque requirement?

Flat 6 Motorsports (who sells the 2-bolt kit) says 10nm for the torque, but good luck getting a torque wrench in there. Not gonna happen. I did the fix on mine and just snugged it up by hand with a short ¼” ratchet. Hasn’t leaked since.

Sounds good.

My independent porsche guy says he can take the “front off”
and do it for $1300. Called my dealer and they are going to look at it and see if they can get it cover under my now expired warranty.
otherwise I understand you need to drop the engine.

I had mine done this last September by the dealership, under the extended warranty. I dodged a bullet with that one (extended warranty).

You don't need to drop the engine to do a "full" timing cover reseal (remove the cover, replace the gaskets, replace ALL the bolts (about 30 of them !)).
The front bumper and radiators are removed, and then there is full access to the front of the engine to do this.
A good time to proactively replace the waterpump, thermostat, serpentine belt and idler and tensioner pulleys.

Are the 2022 and up Macan's (specifically the GTS) susceptible to this issue?

Thanks

Faust T.

no, only V6 models from 2015-2018,
Porsche switched to an AUDI engine form 2019 and the TCC leak is no longer an issue.

When I asked my dealer whether my 2022 GTS has an Audi engine, he replied it did not. So what is the real story about the 2022 GTS engines?

The real story is that your dealer has no idea what he is talking about......
