Proper maintenace such as water pump, fan ballast,cleaning radiators, and IMS replacement would be a start, but remember when these cars were new the first oil change was due at something like 8 or 10 thousand miles per the manufacturer.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

This thing has been up for months. Screaming deal...except for that ticking from the valve out of adjustment. So glad that no one has taken the bait. I wish I had a way to warn off buyers. You can't tell me this guy doesn't know what he has.

What happens if you keep driving a bore scored engine? Is it 100% fatal in short order or could it just as easily drive for another 20k miles? (I hope to never hear that tick tick).
Thanks

Jake Raby explains it in his Rennvision videos on YouTube.
There are people, I think here, have driven their scored engines for large amounts of time and miles while continuously adding oil. From the looks of my #6 cylinder not sure how much longer it would have gone. 808 is right Jake talks about it in his video series.
At least he's honest that it has a noise. He could just have told a newbie buyer that's what all 911s sound like. Not many good options when your engine is damaged.
almost through the rennvision video series on this subject. amazingly informative, even to a non auto mechanically knowledgeable person like myself. highly recommend everyone spend the time watching them all.
^^ At least on the water cooled ones... Air cooled Porsche's are famous for needing valve lash adjustments (non-hydraulic lifters)and all sorts of valve train work...
Sometimes I dream of putting a solid lifters under those cams, but the varicam-plus would freak out on me
Setting lash would be crazy expensive and it would get a bit noisy on the top end.
Do the diagnostics. Don't rely on Internet truth by repeated assertion. If it is something like bore scoring, a look with a usb scope/camera will tell you, but don't jump to that conclusion despite the fact that bore scoring is the current paranoia. It is easily verified or ruled out with proper scoping from the sump.
I'm not jumping to conclusions but if I was interested in buying this car, I'd assume the worst and then inspect to determine if I was right or pleasantly surprised. To more clearly spell out my thinking:
* engine ticking
* engine "smokes while driving"
I suspect the seller took car to shop and pays a couple hundred bucks to diagnose and decided it was time to make it someone else's problem. Otherwise, they'd fix it and either keep it or sell for more than $9.5K.
Maybe it's a ticking ac compressor and it smokes because it needs a new AOS. But as I said earlier, it SOUNDS like classic bore scoring SYMPTOMS. I didn't say it definitely has bore scoring.
Much better of buying a $20,000 car that is in good order and may need a $20,000 repair down the road.... ;-) If you�re not familiar with Porsche�s between 1999 and 2008 read up on the potential engine issues and costs. That said there are lots of Porsche owners out there that have had good luck and the cars are lovely to drive. You can now find 2009 Boxsters in the low 20�s or lower that do not come with these engine problems....
Jake I applaud your commitment to the 996 community. Bought my first porsche 4.5 months ago (2003 4s with <22k miles) and have been a voracious reader of this forum ever since. Though most of the mechanical discussions are above my head, i have absorbed a lot, and researched things i didn�t understand. I�ll never be one to do my own work, and i dont mind paying someone who knows their profession for their time and expertise. I�m well paid for what i do and expect others with different talents to be as well,
I completed the entire bore scoring series. My car, which i intend to never sell, is 5500 miles since IMS retrofit/RMS, clutch, oil change. Drives like a gem, no smoking, no ticking, minimal oil usage (2qt over 5500 miles inc 2 track days).
I ordered 2 oil analysis test kits from LN and have scheduled an oil change next week. I intend to stick to your recommended 5000 miles or 6 months schedule, monitor oil consumption, and monitor UOA changes. Prior to seeing the videos i read about not letting the car sit and warm up, but rather drive off, staying under 3k until warm. You put an explanation behind the suggestion which makes total sense. Glad I�ve been doing that since almost day one.
Please keep the rennvision videos coming, and dont let any of the negative stuff that permeates the internet get to you.
I hope my car lasts forever and we never have to do business, but if it doesn�t, we will.
I gave up on modern humans on the internet a long time ago. The only guarantee is they will be entitled, pissy, objective, critical of everything, and overly opinionated. I made my first forum post about a Porsche engine in 1997, when we were still using newsgroups. Over the years I have dealt with death threats, trolls, and you name it. Keyboard warriors have big *********.
Today the things I stated are the norm, to meet someone that doesn't exhibit this is about as rare as Unicorn poop, and when I meet them, they are normally just like me...
This is is the stuff Jake refers to...
It’s rumored that Porsche Motorsport uses this stuff in the 919 as part of the ‘hybrid’ package. Explains a lot.
That�s right, optimism and machinery maintenance (especially Porsche machinery) have a short lived relationship. It seems that machinery will lose, but somehow optimism will continue. Somehow Jake is the bad guy for salvaging and rebuilding these pile of s**t engines that are engineering marvels????
If these engines didn�t fail at a high rate, there wouldn�t be a Jake Raby. Small problems turn into large bills with these powerplants, as far as I�m concerned you should thank him every day for contributing and allowing you to gain the knowledge he has.
Proper maintenace such as water pump, fan ballast,cleaning radiators, and IMS replacement would be a start, but remember when these cars were new the first oil change was due at something like 8 or 10 thousand miles per the manufacturer. Brilliant move, setting the machine up for many more successful years to come. I�m sure that lovely IMS bearing enjoyed that high mileage oil!
Did you mean subjective ? I don't know many objective people.
My goal is to retire early and move to a state less populated so I can limit my interactions with people. West Virginia is looking pretty good right now!
I have to admit, my wife and I are/where very social people but, the older we get the less we want to be around a lot of people. One of the reasons I left VA to move back home to Hawaii...Now there's to many people here!
When I started working with these engines, it was actually kind of embarrassing. Before I bought a Boxster, a water cooled Porsche had never been on my property. I didn't want the Boxster, and Charles from LN Engineering had to BEG me to help him develop the IMS products, and tools. I wanted nothing to do with it, until Bruce Anderson told the two of us that we needed to do this, and we needed to do it before anyone else. When Bruce spoke- you listened. We did. Bruce was writing for the magazines, and got the letters about failures that no one else saw. In a way we had insider information, and there's a reason why Bruce chose Charles and I to share the info with. It could not be published, or haphazardly shared. He never shared any of it with us, he just said "That bearing is blowing up, figure out why, solve the problem in the simplest way possible, make some parts and you'll be set".
Back then I was the only person in the facility that was working on these engines. The rest of my employees were still building Aircooled Porsche engines. They would walk by as I assembled an M96, and they'd just shake their heads. Today all of them have been cross- trained, and only I build Aircooled engines here. Things went full circle.
These engines were not exhibiting nearly as many problems back then. I initially started building these engines after an IMSB failure, to create the IMS Bearing fixes, and then to make more power, and then, so on, and so forth. Then along came the economy of 2007-2009 period, and the Aircooled business dwindled, while the M9X work exploded... Then the failures really spiked around 2011.
I remember having a morning meeting in October of 2010, with my guys saying "We need more space to store all these blown up cars" and I replied "I'm not going to add any space, because I believe this influx is temporary". Nope, it wasn't... I had to add space to hold 20 more Porsches on our property.
If the engines didn't have these issues, there would still be a Jake Raby.. What I learned about making these engines perform at a higher level than anyone else would drive the business for track cars, and etc. I don't think we'd have the backlog that we have, and Aircooled engines would make up a bigger part of what we do, but we'd still be doing M9X work.
It amazes me when I see a comment like this
"

Jake was around and well respected long before the m96 was even thought of!.
