Well said. This car is crazy good.

 

Chris and others that had heads, cams, oil pump; has your dealer stated if you will now need to use the original oil filter or the new one that came with factory 2016s?

Ryan

 

Unless they changed the threaded spin on oil filter connector on the engine you would still need the E/F oil filter.

 

Isn't that obvious?

 

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.

 

The knock sensor detected increasing engine noise(knocking),which prompted the engine management to retard timing. It's the same process that would happen if the engine were to be knocking from lower octane gasoline or a bad batch. It retards timing to prevent detonation. At that point it wouldn't go over 3K. It's the same as " Reduced engine performance " safe mode to protect the engine. Unfortunately your rod let go(my suspicion),which prompted the piston to go through the case. It is interesting to find out whether this is a cause of the notorious " rod bolt " or it could be the effect of metal shavings thrown all over the engine from the wearing DLC in the top end.

 

Ryan I haven't gotten my car back to have them tell me but I believe Alan is right. I don't believe the filter and filter neck have been changed to the G motor specs.

 

It's sad to read about these issues. Every one is another nail in the coffin of the high reving normally aspirated engine. If I had worked on the development of this engine it would keep me up at night and when it came time for the next engine I'd likely be saying turbo 7800rpm so I could sleep better no matter what the cause.

 

Bruce987, the knock could have been the result of the crank end rod bearing letting loose.

 

Also wondering if there's an extension on the warranty for the engine itself?

 

In some ways the 2014's are MORE valuable than the 2015's. They all come with a very long engine warranty.

 

I specifically inquired as to this when I had my G engine installed and the answer was NO the new engine doesn't get an extended warranty...

 

The 4.0 991.1 GT3 RS if fine so far( we will know in 6 months if any one really puts some track miles on it)The guinea pig was the 2014/15 that we know to this point.

Shame - YES

 

There have already been some RS engine failures in Europe, a couple were even mentioned on RL.

 

Bruce, sorry to hear your story. Really sucks. Thanks for sharing your info with the rest of us.
