Drivetrain FAILURE in my Porsche 997 Turbo and It's All My Fault

[@SpeCifiC0507]

Replace the rear main seal, and really any old seals that are accessible.

[@marvinvisser5039]

100%

[@plus790]

"While you're in there"... replace all seals in that area--RMS, *both* axles, etc. And replace and old, original coolant lines and stuff that you should have done before the motor ever went in.

[@sutherlacd27]

Replacing both axles and all the coolant lines is adding another couple thousand dollars

@@sutherlacd27 definitely will hurt the pocket but I agree with him, while it’s out why not replace it what needs replacing?

[@sutherlacd27]

@@fernandovaca7970 replacing worn hoses makes sense. Hoses that are in good condition don't need replaced....that's just a waste. The axles can be replaced easily enough when they fail.

Matt, I know someday😊 you will have a bigger shop and a proper lift but you and your experience sure are relatable for those of us working in our respective garages! Big job but you are nailing it!

[@matt13ross]

Some day I will! Thank you!

[@gouldnj]

You’re doing great Matt. You really have to ask friends and family to share your videos with the bigger KZbinrs to get a mention, you deserve WAY more subs.

[@matt13ross]

Been slowly, very slowly, growing for years. Maybe someday!

[@NSXavier997]

Do NOT replace the rear main seal unless it is confirmed to be leaking. There is a special tool needed to install it to the proper mm depth and if you don’t have it, and try to install it any other way using any other type of tool, it will leak. Go with the SACHS stage 2.5. It’s basically the factory DMFW, your choice of friction disc and the most important- the “764” pressure plate that gives a higher clamping force.

[@matt13ross]

I was worried about that. It's not leaking now.

[@sutherlacd27]

Perfect advice

[@jonasion]

Gotta give it, to ya. Of all the YT I see, and it has replaced normal TV, films and TV Shows, you're the best of all tubers to engage and involve your audience. The evidence is in how you ask for input and help, and the challenges to comment on something specific and pertinent to the content in question. Nobody does that better than you. Kudos.

[@matt13ross]

I appreciate the positive feedback, thank you!

[@peterrule8107]

I recommend the Sachs 2.5 clutch and replace the dual mass flywheel (good for up to 700-750hp). Going a single mass flywheel is best suited for the track and not the best for the street (very noisy at idle etc)

[@matt13ross]

Yea I don't want to ruin the drivability

[@jeffgould5367]

My Aasco single mass lightweight Flywheel isn't noisy at all...And It drives great.

[@nev997TT]

If you’re going to add more power, Protomotive dual clutch is a great option. I would caution against “launching” these manuals, especially high horsepower. As much fun as it might be, you’ll fry your front diff and new/used diffs and diff parts are hard to come by these days. High horsepower manual Turbos really shine when you roll on it…PDK Turbos are built for launching.

[@rafyg]

That’s the best option in my opinion

[@Jupiterider1]

Unless… he removes the front diff/axles and adds a limited slip in the transaxle

[@matt13ross]

Haha not yet!

[@sutherlacd27]

​@@Jupiterider1on the 997 I don't believe that has ever been accomplished where the car won't go into limp mode when pushed to the max

[@dancruz2698]

Hey Matt, Here’s what I’m running for clutch and flywheel good for up to 700hp with nice ride for my 996TT GT3RS 4.0 Clutch with Sachs 764 Pressure Plate, 964 RS Lightweight Flywheel. GT2 Slave Cylinder Conversion If you don’t want the chatter and noise stick with dual mass flywheel. Light weight is great for rev matching and quick acceleration/decceleration. The slave cylinder mod is nice for good feel and engagement but gets heavy in traffic. Good luck on your search!

[@jeffgould5367]

Dan, I put a lightwieght single mass flywheel in my 997.1 turbo and I don't get what everyone is talking about with regards to noise, sounds the same to me and I had a dual mass before...all 36.5 lbs of it! New one is only 14.5....revs so quick and I've now learned to rev match on my down shifts!

[@stuartbarker671]

More great content Matt 👍😎 Looking forward to seeing you put that trans back on and thread that pin through the release fork laying on your back !!! Good luck to you great attitude 👍

[@matt13ross]

Yes I can't wait lol

[@matthiaskaiser1005]

Mat, definatly change the Crankshaft Seal because its getting hot from the Clutchplate.

[@MyBallers]

Man, I was needing a new video, thank you Matt!

[@dimitristsalatsanis7912]

Please replace those frunk hood struts !!!

[@matt13ross]

They're somewhere lol

[@Slytheslayer]

Definitely rear main seal and any other rear engine access seals or lines. Might as well replace axle seal gaskets on the transmission, input shaft seal. I also saw a rubber hose that had two worm clamps on them. Looks like a recipe for a leak so possibly replace that as well. Anything to not have to worry about the inaccessible back half of the engine and transmission.

[@Sp00n3r1]

I was glad to know you made it home that night!! As stated above, you could do the rear main seal as preventive but if it’s dry I’d leave it. Also the single mass flywheel will give you a quicker rev and unleash a little bit of the torque lost in drivetrain transfer but they do tend to vibrate more than the dual mass so up to you on what you can live with. And from what we’ve talked about I’d def go with the triple disc clutch we talked about.

[@matt13ross]

Yup don't want any nasty chatter or annoying driving characteristics!

[@paddyfriend3999]

Painful job but u have to admit, the feeling of a nice fresh clutch is so, so sweet!

[@coolcolschannel8773]

Also the release fork bearings and clutch cover bolts

[@hotspur1991]

Replace rear main seal while your in there keep up the great content Matt

[@Turboy65]

Famous last words.... "It'll be fine...!" Double checking things is cheap insurance. If you've got the engine out already, do all the maintenance you CAN at that time. Because if you skip a job that needs doing, you're going to drop the engine again anyway. WORK SMARTER NOT HARDER.

[@dubzstylerc9580]

I think one of the most important things that you can replace while you’re in there and what generally people always do on nearly every car is to replace the rear main oil seal which sits underneath the flywheel, it’s definitely a while you’re in their job. It’s one of those jobs that you don’t want to come back and do after you’ve done all this work. As always, keep up the good work.

[@cheapcargarage]

Matt honestly I would resurface the flywheel and put in a standard clutch. You’ll be driving it “normally” more than racing it I’m sure. So make it as useful as possible. Always replace the rear main and front transmission seal at the same time.

[@donaldcaissie]

Great work on removing that transmission!! No time to waste I love the way you tackle jobs! Keep it up

[@matt13ross]

Thanks 👍

[@TheZakk28]

Please do a lightened single mass flywheel! Would love to finally see/hear what that does for the 997.1 Turbo revs. Make sure you do all seals/coolant lines too.

[@christurbo951]

I completed this about 3 weeks ago on my 996tt. Didn’t pull the stud or remove coolant lines. The coolant lines are a big PITA! Looks like you have an upgraded slave cylinder. I stacked some weights on the new pressure plate and release bearing to get the retaining ring installed.

Rear main is a no brainer. btw you gave me anxiety when you popping off the flywheel. I thought this going to be bad if it lands on him. Next time leave a bolt loose or install a threaded stud!

[@jmlh825222]

Comment from an old guy. Someplace there will be a specification for the free play between brake pushrod and the face of the master cylinder piston. Your brakes were probably dragging because the rod was adjusted too “long” and was applying hydraulic pressure even without the brake pedal being depressed. With the brake pedal fully released, remove the master cylinder and place a small amount of modeling clay or similar in the cup on the back of the piston. Rebolt the master cylinder without touching the pedal. Unbolt it and use the clay to measure the “gap” and adjust to factory specs. Been there/done that. Phil

[@thierryblanc9000]

Pour les freins sur la Porsche il y a une tige de poussée réglable entre la pédale et le servo frein cachée par une protection plastique. Pour l'embrayage c'est un embrayage tiré et le système hydraulique et muni d'un amplificateur avec une sphère pour assister la pression aucun réglage possible

Install a GBox Second Gear Detent Kit to protect the synchro (when in pops out of second gear). For $112 its cheap insurance vs a gearbox rebuild.

I did it on my 996tt during an engine out service. It can be done with the gearbox in the car though. It takes some fiddling around blindly.

I had to upgrade from a Sachs 2.5 to a Promotive dual disk because the Sachs couldn't handle 800+ hp. Wish I had gone with a dual mass flywheel because the lightweight single mass I put in, while revving faster, is very noisy and annoying on the street. As others have said, replace the rear main seal.

You were probably at 90 or 95% clutch wear...it was a track car after all...and the sticky brakes just pushed it over the edge so don't be too hard on yourself. I would do the RMS even if you need a specialized tool and the two driveshaft seals for sure. Try using an aluminum brightener acid on the trans once u get it cleaned. It essentially reverses the oxidation and will make it gleam.👍
