I thought I'd post this latest oil sampling report for those of us concerned with valve guide and stem wear. The oil change was at 10Kmi with zero additions. The engine isn't using any oil, it seems....

My 2013 no at 58Kmiles +, almost no oil consumption and no DTCs or oddball sounds from the valve train. And mine has 5 hours of track time, too.

I'm heading toward 60K, rapidly. And mine is also a 2013. And, both oil test samples had zero wearable metals in the oil, even after 8Kmi oil changes. In fact, Blackstone said I can easily go over...

I understood the inspection wasn't retroactive. But, thanks for clarifying...Honestly, I just wasn't sure.

The dealership I've been using has been pretty good to me. Partyka in Hamden, CT. They've...

That's very true. Microphone placement can definitely accentuate certain sounds more than others. I used to do a lot of recording back in my days. But, in this case, it seemed like the engine in this...

I saw a youtube video of what that level of rocker arm and high valve train noise is. The engine sounds like it's a damn bloody diesel at idle. It's incredibly loud. My engine just makes a light...

So far, I've had no issues with the valve guide wear. I'm quickly closing in on 55Kmi with 4 1/2 years on this car. I also have about 5 hours of track time on it, too. Not hard track. All instructive...

I was deciding between the 427 convertible version of mine or the sealed roof coupe. At the time, the MSRP difference was only about $600! Usually, the convertible version is $5500-6500. I was sorely...

People can't believe I've already have over 50,000 miles on the ODO. Mine's a 2013. So far, so good. No problems at all. Just regular wear and tear items. Tires, brakes...

In fact, I drove my...

I really hope this is truly the case. My PT warranty ends this coming September, then I'm on my own. I feel fairly comfortable with reasonable care and use of a top quality synthetic lubricant that I...

Sorry it's been a while. This is my latest oil report at about 45K miles. The oil has about 8K miles of use including 5 hours of track time at NJ Motorsports Park. I now have 50K miles on the car. So...

Hib,

Very interesting article and changes. Were there any other changes to a LS7 built in 2013 as compared to one built in 2006? I think they were: going from lead to a synthetic polymer main...

Very sorry to hear about this. My sincerest condolences. I have a 2013 and I'm still worried about it. Thankfully, I'm still under warranty. And I'm not letting it sit around (except for now as it's...

I will relish reading this updated article. I just did a oil analysis on my LS7 at nearly 40K with 8200 miles on the last change. So far, so good. But, I also understand that's not always a good...

Here are the particulars of the report. Levels of metals and TI elements were extremely low. I received the following:

Sandy,
Please see the attached report for the oil sample that we received. ...

I replaced my GY EMTs in 2014. I went to Michelin Pilot Super Sports. Seriously excellent tire! They're non EMTs, but, I'm not concerned. I had my IROC for over 25 years and it had wide tires, too,...

I have the HELM factory service manuals and I didn't see anything in them about any of this. Interesting.... I remember pressing the WARM and COOL buttons...or was it the OFF button...no...

I just noticed this thread. I'd like to add my 2013 to this thread. It's a bit of a plain Jane, what with the white paint and no other decals or graphics. But, it like it's subdued appearance. :beer ...

I decide a while back to flush all the fluids in my 2013 when it got close to 40Kmiles. Took it to the dealer and they performed the services. Clutch, engine, cooling, P/S, brakes, trans and diff....

I just sent off the oil sample yesterday. The instructions said I could just put it in the envelope and just drop it into any mail receptacle. Hopefully, I'll get a report in the next couple of...

Tuna...I screwed up on sending out the last bottle of oil for analysis. I just dropped it into a postal pickup box and it never got to the lab. I should've hand delivered it to the post office to...

Welp...It happened to me again today. I stopped in to the grocery store to pick up a couple of items, came back out, got in, heard that distinctive difference in the relay clicking, pressed the start...

More often than I'd like it to. Maybe I'm in areas of high RF traffic. What with all the wi fi hotspots around now. And a lot of other things are using RF, too. Like Blue Tooth...I figure the system...

So I'm thinking stray RF is jamming the interrogations between the K F and the BCM? Hmmm...I've read about RF interfering with TPMSs...Pressing the bottom of the rocker does seem to do something...

No.... Just the 'check engine' icon illuminating on the dash. No 'no K F detected' message on the DIC. I've had the no KF condition before, however, and replacing the battery always cured that...
