993's and earlier had Nikasil. Pretty bullet proof. I think it's outrageous that Porsche does not stand behind their motors. Neighbour has had their Macan S engine score. Not worth replacing so they're going to drive it till it dies and buy a North American or Asian SUV as they should have in the first place. She who knows best would love a Cayenne but wisely bought a Palisade.

3.0 T Macan engine is junk. Bore scoring, fuel pumps that leak fuel and wreck rod/main bearings. Ungodly expensive to repair. At one point Porsche was out of shortblocks and long blocks. You can hear them knocking at around 2500rpm… 1-2 times a week we will drain out oil that looks like liquid aluminium

Guess what? Audi based 2.9T is heading that same route

Overstressed engines that run hot with iffy maintenance. My advice is lease this stuff and maybe keep 2 years after.

this is even before getting in rear suspension corrosion issues

IIRC everything at BMW is unserviceable. Need a block? Its toss in the trash because of the laser applied coatings

As I said the biggest issue everywhere even speaking to friends in UK who have shops is machine shops are closing down. We turn away good work because it will be sometimes 3-4 weeks turn around and then you get the part back screwed. We had a few EA888 engines built ready to install but the cores I have now are sitting there. Can’t find a decent place to line bore and clean up the cranks.

I feel like this is just the reality of modern ICE cars. They're engineered well to conform to all environmental/emissions regulations but it seems like it's a the expense of longevity and reliability. We've manufactured ourselves into driving the iPhone and Android equivalent of cars where in 5 or 10 years it's basically thrown away.

While they were designed to be rehoned, it work for m96/m97 unfortunately. The silicon particles in the alusil are simply too large (up to .003”!) and are what break off and cause scoring. They fixed this by going with a much smaller silicone particle for the 9a1 which can be bored and honed.

As for the desposible comment, I’ll assume that is in reference to SUV’s. Because a 997.1 with a 4.1L is a much better driving experience than any of the newer pcars I’ve driven. The 997.2 is great, but it’s also about when the connection between the driver and road started becoming more muted IMHO.

And no, I’m not from Canada. But my girlfriend is flying to Calgary today so I figure that qualified me to join the discussion. 😂

We'll allow it .. lol

So why is it that Asian and American vehicles do not appear to be suffering this fate? My wild, unsupportable guess is EU environmental laws with emphasis on the mental.

Gregster

They sure do suffer from it. Look up all the problems of late with Toyota engines. Look up the problems caused by cylinder deactivation on GM V8s. Fords brilliant idea using a wet timing belt.. I can go on

ronnie993tt

Cylinder deactivation - almost as stupid an idea as the current stop/start nonsense. At least you can shut it off. I have friends with all of these cars, and no one has ever heard of, let alone experienced, major engine problems. Yet I'd say 1/3 of the people I know with water cooled Porsches have had engine failures.

02 C2 130k Had misfire on cyl 6 and drivers side exhaust tip all full of oily soot

Greg what do you see? bore scoring on the cylinders and deposits on top of pistons? what is customer gonna do?

Gregster

yep and visible pooling of oil. At this point we aren’t sure but a used engine could be in the picture. Im suggesting a rebuild but the “while you are in there” will add up in any case. Tbh I didn’t look at the other bank. No point is there is damage already.

An 996 C2? Not exactly a collectible. Just drive it till it dies and then trash it. Isnt a rebuild going to cost at least half the value of the car?

vern1

Alusil was ****

Dont agree with your driving assessment though. I had a 997 with a bored 4L and headers/200 cell cats etc etc. Loved the car and sounded like a hound from hell. But it did not drive anywhere near as nice as my current 992 S which is faster (obviously) with a much better suspension and chassis. My 993 drove better than my 89, and my 997 drove better than my 993

Cheers

Ouch that is bore scoring and unfortunately that will cost over $30,000 to rebuild the engine. Agree mine as well just drive it till it dies.
