996 valve guide wear vs 911 valve guide wear

[BReyes]

How do 996 valve guides wear compared to say a 3.2 liter? As we know the bottom end on a 3.2 withstands alot more than the valve guides.

Thank you.

I haven't heard of any issues with 996/986 valve guide wear.

Do you think they are a problem? Are you having problems?

Here is my thinking. When I open a 911 motor with 50,000 I expect only to replace a few valve guides switch a couple of valve,maybe buy one. Is that the extent on what I could expect on a well maintained 996 motor?

You won't have to open the 996 engine at 50K for valves. Mine has 55K and runs perfectly, like a new engine, really (it's original to the car).

I would think by now that Porsche would have it's act together like Toyota does with the 4-Runner. I can't make my 4-runner break down.
