I have had two occasions so far when I saw a drop or two of oil on the garage floor. The dealer told me the timing chain cover was leaking. While none of us want any leaks, this one seems relatively harmless in comparison to a “fix” that itself sounds a bit suspect.

I am somewhat inclined to just leave it be, unless it is going to get worse and worse over time. The one indie in town who will work on my car told me yesterday he has decided not to touch that particular repair. So that leaves me with the dealer to repair the leak, but it sounds like even the repair is no guarantee.

Can you see any major downside of just letting it go for now? Thx

I don't see a major downside but be aware that there is a large semi-absorbent cover under the whole engine area that will absorb quite a bit of oil before any leaks. So if you're seeing drops on your floor then there's likely quite a bit more leaking than you might think.

If I had know about this kit I wouldn't have had the dealer repair it, I would have just done it myself. The instructions that come with it are quite clear...

The oil will eventually get all over the accessory drive pulleys and belts, deteriorating the belts and possibly causing them to slip. The main components that get covered in oil is the AC compressor if leaking from the left side or the alternator if leaking from the right side so maybe those can get damaged. No telling how long that would take to happen though. In the grand scheme of things, this issue is definitely more of an annoyance than catastrophic.

Even though seepage was documented when mine was still under factory warranty, Porsche still wouldn't good will the $800 timing cover repair. I had a valve cover leak earlier that was covered under factory warranty. My valve cover leak was worse than my timing cover leak.

When it (timing chain cover) was fixed the first time, the tech should have used a strong flange sealant (mine used something - I forget which - in the Loctite 5xxx series) to ensure that it would stay sealed even if some bolts broke again. Or, should have used steel bolts.

If it’s leaking a second time after a year or three I would be very, very interested in making someone else pay for the re-repair.

Check back to the dawn of this thread when I had ours done under CPO. 2018? So, 5 years now, all good.

Here is my experience as a 2016 S owner of six years with 52k miles. Front clip pulled twice for this issue. At 30 and 50k miles. 40k in warranty repairs. When it was repaired at 50k miles the dealer had 7 Macan S of the 2015-2017 in for the same repair issue. No update to the fix just put it back the same way. The 2018 S and beyond have the same specifications but a different engine. Wonder why. A month before the warranty expired I traded it straight across for a Rav 4 and ordered a Cayman GTS.

Can anyone confirm these are the correct numbers for the new bolt and spacer?

When I took my car in for an airbag recall issue, the dealership noted the leak. Their “fix”, before escalating, was to replace some bolts with an upgraded part. That cost around $1300. Their track record for success for that fix resolving the leak is running around 75%. If that doesn’t work, then they get into the timing chain cover, gasket, etc. That fix is around $20,000. Unfortunately, my local indie wont touch that repair and he is the only indie in town who will do anything on Porsches.

did they use steel bolts on yours?

assuming they did the entire reseal?

My tech used the aluminum fasteners as per the parts catalogue as of 2019. But, as I wrote above he used a strong oil-friendly sealant. Half my chain cover bolts could snap and it’s not going to leak.

Yes, they resealed the whole thing. Engine was out. Pretty sure I posted a picture of that.

This is where my long-ish post on the subject start:

Is this really true I can't believe it? Has the brand gone down the outhouse shaft?
Aluminum has deformation, shear and tensile issues, problems from elongation and cracks. Why not use aluminum tubing in brake lines, shear cracks from vibration for one thing. It was illegalized in mobile home wiring for fires due to deformation issue from sitting under screws in service panels and wall sockets and working itself loose over time, especially in circuits which ran warm.

Porsche a brand which built a reputation on superior engineering and construction for high performance automobiles. What are customer expectations, that the manufacturer choose a part with lower tensile strength than mild steel and very well known failure issues due to heat or vibration and deformation from compression and elongation. Wonder what kind of nitwits are being hired as engineers now, oh yeah Boeing doors right...

Any auto mfg that uses aluminum bolts or screws in or on an engine, which happen to vibrate and produce heat should have their butts handed to them in a lawsuit. Any attorneys listening, this is an easy class ENGINEERING 101 for crying out loud!!!
