2-Part Webinar LIVE on YouTube- Focus on Bore Scoring

Due to demand, we will be streaming tonight's Webinar LIVE on the Rennvision YouTube channel. Come join us! 8PM ET. Click the link below. You Tube

Will this be recorded in some fashion so we can see it later? The webinar thing is tough during the day, or evening too because I go to bed early. I�m very interested I what you and others have to say, but it�s tough to fit in the schedule. Had to make time for a customer today for a new product release to watch one.

Recording is a bit of an issue when it comes to piracy, and enforcing copyright on the material. Its impossible to meet everyone's schedule. The 100 seats in Zoom filled up in 48 minutes after the webinar was announced, so we decided to stream it live. Future content on the topic will likely be via online classes, and won't be free.

I don't mind paying for it, I was hoping I could access it somehow later. There's always useful bits of info in these.

The webinar turned out great.. 2.5 hours of insane detail from the panel. We were averaging around 200 people live, and had no technical difficulties. It was great!

I'd love to attend next time!

Thanks for this. I was only able to catch an hour in the middle due to work constraints, but as always, the discussion was good. Good information, good experiences shared. I look forward to the next.

It was a great presentation all around, looking forward to part 2.

Thanks.. Things will get interesting in part 2.

Unfortunately, I had to miss the webinar. Can anyone post the highlights or any new learning. I'm a believer in the FSI approach to things, LNE products, and Lake Speed Jr. knowledge, so you could leave out the basics (e.g. change oil every 6 months no matter what, etc...)?

Bummed that I missed it. I was signed up for the webinar but got called out to work at the last minute.

I got the last hour or so. It was interesting when they talked about what the engine builders in the UK & Germany were seeing that were common to what they are seeing here in the US as well as what is unique among the different countries. Gasoline make-up and their the detergents in different regions (locally & globally) and seasons do have an effect on the engines, the injectors, and overall health of the engines. Lots of injectors being tested and while they may look and spray good, they aren't actually performing that well (see previous statement on gasoline). Also seems the Lokasil roughness on the OEM cylinders may not have met Porsche specifications.

I wouldn�t say there was any groundbreaking information but each participant was able to speak at length in understandable yet still scientific terms about all the factors responsible for the bore scoring phenomenon. Among other things, Lake discussed the impact of changing gasoline formulations on injector performance as well as how UOA results can be misinterpreted as larger size wear particles end up in the oil. Charles went in depth discussing the different materials used in modern engines to reduce weight and add efficiency, as well as changes in piston skirting materials. Lots of discussion about rich starts, leaking injectors, etc and the damage which results to the barrier between the piston and bore from such issues. That is just a portion of what was discussed, but from a layman�s perspective it was easy to follow and well worth staying up past my bedtime to listen to it all, lol.

Looking forward to Part 2! Great job by the panel

Sorry I missed the first part. I’d definitely like to see the second part. Especially if it covers the advantages of Nickies.

Well, here’s some good news I just got in my inbox. If you’re not a member, you should be.

I watched the whole thing but didn't realize it went that long. I guess that means it was interesting. I thought I knew all there was to know about bore scoring but I definitely learned a few new things.

As great as the presentation & discussion was on all fronts, as i watched it i began thinking about how an outsider, a non 996 owner, maybe someone new to Porsches who always wanted a 911 (me 2 years ago) would have viewed it? Would I have bought my 996 had i seen this webinar back in 2019 when all i was worried about was the IMSB issue? Probably not. Do i regret buying it, absolutely not.

Interesting point. And in some cases it must be true. Maybe the folks that get chased away have zero knowledge on engines and zero capacity to deal with adversity when it strikes. It's a good thing they don't buy one of these. Keeping them out of the hands of folks that can't afford them. If I'm making $50k/yr, with 2 kids and I can fix anything, I might want to buy a 911. But knowing there is a X% chance of a $10K-$30k rebuild, I'd go back to looking at Toyotas. The current resale prices might preclude this case anyway. Every broadcast has some target market along with some goals. Maybe the video will predispose these cars to folks that can understand that there is a chance their car will end up with a problem but have experience fixing things and can see that there are solutions, albeit expensive, to these problems. Regardless, I totally agree with no regrets. One of my friends said I would probably get buried in it. Well... Go Packers Go Chiefs

This is honestly where I am at. I've watched some of the content from Flat 6 and its all been great. When I was buying it was IMS this and IMS that but not much on bore scoring. I honestly don't know if I would have purchased my 996 if I knew about the bore scoring.

All of us on the panel agreed that we'd not hide any feelings, or facts during the Webinar. We are all straight shooters that tell it the way that we see it, from where we stand in the industry. Basically, we aren't going to tell people what they want to hear, for the sake of buyers, or sellers, or the marketplace. Our content is 100% technical, and will remain that way. Nothing will get in the way of conveying what we see, and what we live for a life that is filled with dealing with the pitfalls of every Porsche model since 1950.

Everyone on this forum appreciates and should be grateful for that "straight shooter" approach, and those few who don't are probably just plain jealous of your hard work and success

Everyone on that panel shares one thing in common. We are all primarily focused on making things work, not marketing, or making money. To me, the thing that kills development, and invention most is money, and "success".

I meant success as measured by the respect of your peers more than measured financially. Anyone can make $, respect is earned.

I understand. Many of my peers used to laugh at me for working on these engines. This was back when you could buy a new one in the crate for 5-8K bucks. They considered them disposable back then, while I considered them the star of tomorrow.

There are many of us out here who are very glad that you decided to work on these engines...

Come join us for the second part of the FOCUS ON: BORE SCORING webinar LIVE on YouTube. Everyone will have the opportunity to post questions to LIVE chat throughout the broadcast. Looking forward to seeing the Rennlist community there! Here is the direct link: You Tube

I can honestly and confidently say I wouldn't have.

2 minute warning! The webinar is about to begin.

Just got home from a 120 mile drive in my 996...ready to learn more!

Nice presentation. It's pretty clear that the wear that leads to bore scoring is quite complicated. That said, it's also pretty clear that this is absolutely a lifetime issue and all engines will end up with it at some point. If you take this thought to the next level relative the value of these cars, it seems we will need to live through the period during which the masses realize this and come to terms with it. Same thing happened with IMSB. Prices are just recovering from IMSB realization now. It doesn't bother people as much as it did. Thanks guys for the excellent discussion!

Thanks for doing this. I had some issues hearing audio at about the 45 min mark so I had to log off but still enjoyed what I heard up to that point.

I am cross posting my comment from the other thread, since it also pertains here: Yes, a lot of what we covered has already been covered. The main goals that I had for these webinars was to put all the information as part of one resource material, and to have people on the panel that represent every facet of what's involved. This is why Lake, and Tony were asked to be there, as well as Wildbill. There's so much back and forth on this, that people need to hear it all at once, so they can weed out the BS, and streamline their decision to keep the car after a failure, or sell it as a roller. A lot of bore scoring is misdiagnosed. Some cars that have it, are diagnosed as "bad lifters" and those engines do have scoring. On the flip side, a lot of engines that see scope inspections are misdiagnosed because the person doing the test can't differentiate normal cylinder appearances specific to these engines, from actual bore scoring. Remember, every mechanical thing ever created has two facts related to it. This varies from roller coasters, to aerospace, to Porsche cars. The fact is that the only guarantee is if the doesn't fail first, it will wear out. Every engine starts to die the day it is started for the first time. Don't ever forget that. You can take the bore scoring failure, turn the whole thing around, and create something that the factory never could. IF you LOVE the car, bore scoring can be the best thing that ever happened to you, as long as you can afford to do it right. This failure is much different than the IMS issues. I also know that the IMS issues did NOT hurt the value of these cars; most buyers had no idea that the IMS issue existed until AFTER they bought the car. What hurt the values of these cars was the economy at the time. Look at Mercedes, BMWs and other cars of the same era- same deal. Why are the cars bringing more money now? Well, its because people have figured out that these cars are the last of the analog Porsche cars, and that everything that came after them got too big, too complex, and too de- sensitized. These cars are also better and simpler than the newer cars, and this will continue to be recognized moving forward.
