Todd,You left out the Most Important Part.........................
Bearings#Bearings #####
The difference between a Chevrolet Cobalt that lasted till 148K Miles,Compared to a 2008 Toyota Prius that lasted to 420K miles is the Bearings,Japanese Bearings are Significantly Better if you purchase the right ones.
Todd,Great Work as Always!!!
Great point! We've pulled apart stock and modded engines at 130k+ miles and could swear the rod and main bearings are brand new.... The int shaft bearings get worn from excessive load on the cams and the rear main thrust from the heavy clutches these cars need for high power. But otherwise the lower ends in these would go stupid high miles. That's the cost of performance though! Can't do without a clutch to hold the power!
Great job! I recently had an extensive engine out service and took care of a lot of these potential issues but I didn’t even know of some of the others. Thanks
Oh that's fantastic that it helped you. There's a few others we didn't cover like intake lifters update and oil gallery plugs but did get most of them! Let us know if we can help you.
Another great video Todd! Well done!
Thank you! 😊
Amazing job 👏🏻👏🏻 waiting for the 997.1 turbo video
We're Working on it! 😊
997.1tt videos are both up now!
Part 1 czcams.com/video/URrr1Xv7j0o/video.html
Part 2 czcams.com/video/viAa4mRfA0o/video.html
Excellent content there Todd👍🏼
Thank you!
what's the number of the TSB for the oil gallery plugs? i can't find it! thanks
The TSB was on the 3.8 and 4.0 GT3 engine case freeze plugs, but is relevant to the 996tt/997.1TT engine cases as well. It was showing how to properly stake the freeze plugs in place to keep them from blowing out randomly. It was showing the large one by the bell housing on the bottom of the case, and the other large one inside the bellhousing. When you purchase a new engine case, they've learned the hard way and do stake them properly. I searched for it for a while and can't seem to locate it. When it turns back up, I'll shoot it over to you. It was originally sent to me by our distributor in the UK, NineExcellence. Ken may have it floating around.
Arrggg.... 😢That's all the crap I see! ❤
Yes I can see that from engine builders perspective! But that also why you're so good at it! 😊
do you have any tips for abs/psm issues after increasing boost with hybrids?
There are definitely a few annoyances with the Abs/Psm system on the 996tt. My personal car was doing a strange thing where it would tend to lock up the front right tire in cold weather right in the middle of a corner. That turned out to be the Yaw sensor in front of the shifter. No errors... On the track, the PSM tends to lock up when part throttling out of high speed corners. There's a hack for that where people install a switch to disable the yaw sensor once you're started up. it won't flag any errors, keeps the Abs on, but disables the PSM which is cool. The better way to go is to install a GT2 or Motorsports ABS unit and remove the psm. With that done, I can code out the PSM from the ecu and all is happy again. So, there's a few tips for ya :)
@@protomotive my yaw sensor was doing a lot of random shit on my Autel diagnostic
@@protomotive Fabulous info, do you have a link?
@@sidewayssam this is from Planet 9 forum.
Actually the "wiring work" is really easy. Not harder than hard wiring a radar detector.
Just locate the Yaw sensor under the carpet on the hump, by the drivers right shin. Cut the ground wire (brn/yel) and install a rocker switch between the two ends of the ground wire.
When you want PSM OFF, turn the switch OFF.
When you want PSM ON, turn the switch ON, and cycle the ignition.
I soldered in longer wires an installed the switch on the trim panel under the parking brake. This trim panel is really cheap and simple to replace. Plus the switch is easy to reach.
On the street or in the rain, I have it ON.
On the track, in the dry, I ALWAYS have it OFF.

@@sidewayssam Mine never flagged an error for it, but replacing it solved the issue I was having. I did find a Non-PSm ABS I was going to swap out, but never seem to get the time to tackle that one.
