There have been several RS engine replacements recently in US. No details yet as to reason of failures but from what I'm told there are no similarities so they appear to be isolated issues. I will try to elaborate once more details available.

^^ LOL.
Depends on the track; I do short shift as I don't feel there is a lap time advantage revving the snot out of it at each gearshift, the car has nice torque (GT2RS anyone?).. But yeah, redline plenty of times..
These cars want to be broken in on the race track me thinks..

My 2015 "F" series had a major failure at TWS over the weekend. It lost power then a lot of clanking noises followed by billowing smoke at of the rear end... lots of messages being displayed ending with "oil is low" or something like that. Then the engine just shut off and wouldn't start. Towed to the dealer and was told that I had a hole in the top of the block. Now I'm waiting to see what comes next. The dealer indicated that this would be a new motor...crossing fingers.
This my second failure. Last year I had a catalytic converted melt!

If I may ask, how many miles total, and how many were track? Which dealer?
Better an engine failure coming out of 3 than going into 1,2 or 7!

I have about 18,000 miles on the car of which the first 2000 were break in... I followed the recommendations. I estimate that 300 miles are track. As you can see I drive my car daily and don't plan on saving for next owner! Oops I miss calculated my track miles... it's more like 9600 track miles! Also I use Mobil 1 0/40 Euro... I have it changed every 5000 miles.

I have a 2014 GT3 with 7,100 track miles plus 1,600 road miles. Haven't had the piston misfire problem yet.
Last week, the car went into limp mode due to a cam sensor warning. The dealer mechanics dropped the motor to check the timing and confirmed that there was a timing problem due to some wear on a spacer.
They further disassembled the engine to replace the spacer and I went in today to inspect the internals for evidence of the cam lifter wear that is the primary topic of this thread. There was some barely visible wear of the coating on several lifter arms (#3 was the worst) but it was pretty minor. The master mechanic is going to consult with Germany, but he doesn't think that it is bad enough to be judged a problem. If so, I will report back.
Just another data point for the records.

It would be great if the top end repairs and F&G motors have thicker valve lever DLC coating.

Got some additional information while talking to the mechanic that always works on my car. He of course was concerned when he heard that I lost oil since I just took it in for an oil change. He thought maybe he didn't tighten something. Anyway he pulled the telemetry from the car that seems to confirm some of what I experienced. He said that when the catastrophic failure occurred I was doing 3500 RPM's. This coincides with what I noticed; coming out of turn 3 to 4 I hammered it and noticed that it wasn't doing much more than 3000-3500 RPM's and not moving. That's when the engine blew, I feathered the throttle thinking it just needed a reminder that we were on the track. By the time I made turn 4 I was coasting (offline) and noticed smoke coming out the back; came to a stop on turn 5. The mechanic also said that about 30 seconds prior to the failure the crank detected a knock and went into anti-knock mode, trying to adjust the timing. He thinks this is when the failure was probably starting. He thinks the issue is down somewhere in the crank, but Porsche hasn't authorized him to take the engine apart. He also said that the engine had multiple holes in the top of the block, that probably cylinder 1 and 2 let loose. He is taking pictures and said he would provide them to me at some point in the future... stay tuned... still waiting on new motor.
Sorry, I know it isn't funny.
