Great info Todd. Always something new to learn

[@protomotive]

Thanks for watching! I'm sure you have a few tricks up your sleeve as well!

[@Slow_911_]

Another great video Todd! Well done!

[@protomotive]

Thank you! 😊

[@azizbohamad3861]

Amazing job 👏🏻👏🏻 waiting for the 997.1 turbo video

[@protomotive]

We're Working on it! 😊

[@protomotive]

997.1tt videos are both up now! Part 1 kzbin.info/www/bejne/i4PVo2SOq5ydZtE Part 2 kzbin.info/www/bejne/rJqkkmejh8t0ZtE

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!!!

[@protomotive]

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!

Excellent content there Todd👍🏼

[@protomotive]

Thank you!

Thanks for posting this and subbed. I have recently bought one and this info is super useful. Just when I thought these engines were bulletproof 😮. Problem with spoiler ram leaking on mine.

[@toddknighton]

Congrats on your new friend :) A lot of people have been updating the spoiler rams to the electric rams, or gt2 wings can be fun as well :) you can also jump the switches on the rams to stop the error, then leave it down, or prop it up.

[@davidleigh7698]

Thanks for the advice, much appreciated. Wondering if you can split the rams and replace the seal?

[@protomotive]

I've not tried that, but I'm sure a hydraulic place could take care of it if you can't get them apart. let me know if you succeed!

[@AN-ce1nd]

A TTB!

[@protomotive]

I'm Assuming you're saying it's a ticking time bomb? These do have a few issues to deal with, but having to work pretty hard to find top 10 issues on these is really saying a lot. The 996tt has really lasted well and aged even better. Going on 25 years old now, it's amazing these still hold their own against the top supercars today, and are really only now showing a bit of age! I love my 996tt :) It's really an amazing car.

[@Jupiterider1]

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

[@protomotive]

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.

[@Domusan]

How much did it cost you?

[@kd5135]

Thanks for the video. I'm not new to the 996, but recently purchased my first 996 TT. I'm noticing a rattle sound and wondering if it's the intermediate Shaft Bolts come loose and rattle? Is there a way to determine if that's the case? I have a video I can share.

[@protomotive]

I'd be happy to take a listen to it. If it's just on startup it's more often a chain tensioner. Lifters give you more of a tick tick tick vs. a rattle. If the sound is coming from the center back of the engine, it's most likely the intermediate shaft. But even relatively new these make an odd noise back there. Possibly a combination of the turbo scavenge pump, intermediate shaft, chains, and oil pump having a lot of gears down there in close proximity. Do also check simple stuff like the serpentine belt drive idle pulleys and tensioner as well as the front pulley is tight. There's so many things that can create similar sounds, it's most important to look at the where and when to better identify the source of the problem.

[@kd5135]

@@protomotive Thanks for the quick reply. I have sent you email from your website-sales

[@protomotive]

@@kd5135 On it :)

[@gimmitsgarage]

what's the number of the TSB for the oil gallery plugs? i can't find it! thanks

[@protomotive]

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.

[@sidewayssam]

do you have any tips for abs/psm issues after increasing boost with hybrids?

[@protomotive]

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 :)

[@sidewayssam]

@@protomotive my yaw sensor was doing a lot of random shit on my Autel diagnostic

[@sidewayssam]

@@protomotive Fabulous info, do you have a link?

[@protomotive]

@@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. actual link: www.planet-9.com/threads/psm-on-or-off.27747/page-3

[@protomotive]

@@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.

[@cynthiaknighton4680]

Arrggg.... 😢That's all the crap I see! ❤

[@protomotive]

Yes I can see that from engine builders perspective! But that also why you're so good at it! 😊
