Thanks and I like how you think, frugal but willing to spend the money where it clearly adds value (such as the LNE resleeve).

I put together my own list a while back with various add/delete options, the goal was trying to control costs. One interesting thing I found was that the head bolts on later 996's and 997's aren't torque to yield and can be reused. There's a good thread on this by @Porschetech3 over in the 996 forum. Yet everyone replaces them thinking they are stretch bolts. Not a big cost but stuff like that can add up.

I've attached my list in case anyone is interested but the prices are probably stale now. This is for an M97, some PN's are different for an M96.

BTW, what did you end up doing with the IMS?

I bore scoped 2 low mileage (under 50k) 3.6's before getting my S. Both had scoring. Glad yours is clean.

Very nice post and thanks for sharing. L8 APPEX

Sound's freakishly odd and unlucky.
I see you're new here---->If you follow along like I have over the last 10 years folliwing all the Bore Scoring Threads and posts, you will no doubt realize the "S" model is much more prone.
Of course "S" owners don't like the news and occasionally disagree
Do you own an "S"??

That's why I was originally looking for a 3.6 as there seem to be less instances of them scoring although LN and Hartech say they see 3.6's regularly. The first one I looked at was a red 2006 C2 at Porsche of Austin. It had 31k miles on it. TPWS did the borescope PPI and came back with scoring. When I was walking around Porsche of Austin looking at their cars I noticed a tech getting cars ready for test drive. He had a roll-around battery to jump start them. Once starting, he would immediately hold the accelerator down and run the car at about 4k rpm to charge the battery - on a cold engine! I'm wondering if this is how that 2006 ended up with scoring.

The next one I PPI'd was a 2008 C4 (I LOVED that car) with 48k miles on it. It was meticulously maintained. I posted photos under the thread titled (Help me interpret the results of this PPI). It had started scoring (at least from the sump side). I was pretty heartbroken over that one and even considered buying it and rebuilding the motor.

Here's the thread with pics: https://rennlist.com/forums/997-foru...e-results.html

The car I finally bought was a 2005 Yellow S. The car has 97k on it and was so clean and inexpensive I couldn't pass it up. I could rebuild the motor into a 4.1L and still be at or around market value. At that price I had to move quickly and couldn't PPI the car. So now I'm driving a really nice C2S that could end up needing a rebuild although it's not showing any symptoms. It's ok if I do, I really love the car and it'll be worth it if I have to rebuild it.

Congratulations on making it this far! Good luck this weekend! I just finished the same process with my 2006 Carrera Cabriolet - bore scoring with only 30k miles and entirely warm climate (San Diego and LA). Went the LN Engineering route and rebuilt myself. Started her up on Father's Day - what a great celebration that was!

Smart move buying a higher mileage S

Not to derail the thread, but holy chit!!! Note to self, don’t leave my “S” at Porsche Austin!

Yeah, I didn't know what to do when I saw that. Do I go to the guy or go talk to someone at the dealership who won't do anything with the information? But I would definitely scope any car coming out of PofA.

Also, I'm being kind of generous to them when I say he was holding the RPM at 4k. It was probably higher.

Ready to go back in.

I might have missed it but how long did reassembly take?

spessx

Nice work, sir! Can’t wait to hear you’ve fired it up.

About 20 hours to get to the long block. Another 20 hours to get all the ancillaries back on, there is just a lot of wirings, intake, secondary air, AOS pipes, vacuum lines, AC, PS pump, alternator, belt pullies, belt and brackets galore. Some has to go on in a very specific order or you end up taking somethings off. Getting the really heavy gearbox back on was not a walk in the park...

Leak down test for Cyl1 and Cyl4 showed 10% leak down. Good for a new valve job, new rings, new liners that has not bedded in. It also confirmed that cam timing is accurate.

Found another plate cover missing (did not come back from LNE).

Thank you so much for the great job documenting this! It does not look at all scary to do.
