Best 991.2 DIY Major Service video to date.

[@TommyLGarage]

Thank you! It means a lot

[@nydo]

I don’t own this car, yet I sat through this whole video. Very informative and entertaining. Thank you.

[@TommyLGarage]

Glad you enjoyed it!

[@gunterhoffman6034]

Tommy, you've truly nailed it with this insightful video on Porsche service maintenance! It's not just about the drive; it's about the longevity and reliability that come with proper servicing. Thanks for shedding light on this often overlooked aspect of owning a Porsche. Keep up the fantastic work, and I'm looking forward to more content like this!

[@TommyLGarage]

Thanks for the kind words. I really appreciate it

[@deniswalks]

Porsche dealers would definitely dislike this video. Thank you! It was very fun and informative.

[@TommyLGarage]

I appreciate that! Will you be tackling this job ?

[@deniswalks]

@@TommyLGarage Of course i will! Looking forward to buy 991.2 next year, so any information about owning this car is a gem, especially so professionally recorded :)

[@MichaelNNguyen]

Another awesome video Tommy! A lot of work going into making this video, much respect brother.

[@TommyLGarage]

Thanks Michael!! Hope all is well.

Good job, Tommy 🎉

[@TommyLGarage]

Thank you! 😃 tackling it yourself too?

[@jusssy5078]

Hi, one of your best vids so far, well done and produced. Cleaning the inside of the car behind the bodywork is the kind of attention to detail I love that I assume you don't get at a dealer. Cheers.

[@TommyLGarage]

Glad you enjoyed it! Cleaning the inside made me feel a lot better for some reason :)

[@JaySpeed911]

Thanks Tommy. I used this to get my oil change done. Next step may be the BMC oil filter. I have about the same mileage that you had when you made this video.

[@TommyLGarage]

Glad it helped!! Kudos for doing stuff yourself

[@tonydamiani8029]

This is a great video and insight into why Porsche servicing at a garage is so expensive. Much more difficult than, for example, Mercedes. But still easier than many Audis.

[@TommyLGarage]

Thanks! And yes I agree. Audi maintenance is insane.

[@DavidS-x9y]

By far the easiest car I have worked on, just did the PDK and final drive oils, plugs/coils, oil/filter change and K&N air filter in just a few hours. Thank you for your videos! My M4 is gone and I don't miss her!

[@TommyLGarage]

Always need to trade up! :)

[@donrogers1000]

"By far the easiest car I have worked on" Say what? How many cars have you owned where you need to jack it up and remove two wheels just to get started.

[@stephencurry8552]

I am stoked that the algo brought your video to me. Although my 911 is not the same model. This video provided many details. I work on all my own cars which is the only reason I can own what I do, including custom cars.

[@TommyLGarage]

Thanks for visiting! I love DIY and same thing here - doing it myself is the only way I can afford it

[@Peanutdenver]

The 991.2 Carrera T may be the best bang for your buck sports car for the track...and street as well tbh. Great detail on the vacuum lines(bottom line).

[@davidmiller1938]

Thanks Tommy. I hope my Porsche mechanic is as careful as you are 🙏🏻. And, it will be easier to pay the bill knowing how much needs to be done for the “simple jobs” you DIY’d. Very impressive.

[@TommyLGarage]

Thank you. I have seen Porsche mechanics at work and they seem to care a lot actually. Porsche mechanics are a certain breed.

[@donacianoc.sandoval2587]

Tommy, you're amazing. I loved all the angles you took with the camera to show how to do each thing, the music for the majority of the video gave that calm feel. I wasn't sure what to expect when I clicked on your video. I thought it was going to be the usual overhyped dude just talking about how awesome his 911 is. No. I was wrong. You were geuine, and humble about working on it. I have always steered clear of exotics because of the maintenance being too tedious, expensive, or they have some propriertary tool designed specifically for one job, and you can't do it without it. You've showed me its just another car. Same principles, you just have to tear it into to learn it. Gives me hope to buy one one day. To that, you've earned my sub, thanks a bunch Tommy!

[@TommyLGarage]

Thank you so much for the kind words. I really appreciate it. And you are right, at the end of the day it’s just another car. You should not be intimidated by it.

[@sunnymon1436]

Bosch aren't known for being consistent on pre-gapping. But also, if you gap your own spark plugs you can set them to a wider gap and get better performance from the engine. Yep, you might have 0.7 mm as standard, but apparently the best performance comes at 1.14 mm. It really does make a difference (Of course, if you gap them too wide, you'll notice misfires).

[@TommyLGarage]

Good callout. Thanks !

[@DontTellMeMore]

Great video. For your safety, the quick jacks as used are backwards oriented, per the manual, need to lift the heavy end of the car over the jack base, not cantilever.

[@chuck121370]

Great job Tommy! Was a pleasure to watch you work. By the way, what music what that as you changed the spark plugs? Very soothing :-)

[@De132an]

Very nice! Informative and easily comprehensible. My 992 T coming before year’s end. Definitely looking forward to more T content from you.

[@TommyLGarage]

Congrats on the T! You will absolutely love it

[@shawneli5078]

Really like the video. It would have been informative if you showed how the spoiler and the tail lights were removed.

[@TommyLGarage]

Thanks! Will show it soon

[@craigwilliams6734]

I really enjoyed that Tommy, but for me, I would be so concerned about cross threading the spark plugs!! 😬😜

[@TommyLGarage]

You’ll be fine!

[@hemandave7584]

Tommy, thanks so much for this! I really enjoy your content and i appreciate your attention to detail. While it seems pretty straightforward, I'm not brave enough to attempt this on my 991.2. Keep up the great work!

[@TommyLGarage]

Thanks! I’m sure you could easily tackle it. With patience :)

[@-JorD-]

Cool vid again!! Nothing like doing work on your own car ;-) rewarding... One tip? Please get rid of the rubber line attaching the gas cap to your car. No Function and a lot of risk of banging the cap to your car.... There is handy spot where you can put it when filling up. And let's be honest, when was the last time you've dropped a gas cap... hahaha Anyway, keep it up! love your videos!!

[@TommyLGarage]

Good call on the gas cap rubber line. Will remove it asap.

[@zhaostephen5800]

What a great video! I still didn’t convince myself to work on my Porsche

[@TommyLGarage]

You can do it! It’s easy

[@spacemarine8289]

It just has to be one of the hardest cars to work on with the engine in that position.

[@TommyLGarage]

But it’s so rewarding !

[@gtrguyinaz]

Great review… so how much does the dealer charge… in the USA… 2500.00 is my guess….

[@TommyLGarage]

I believe $4k

[@TheMatadore]

Good work. It is absurd how inaccessible Porsche has made these engines.

[@TommyLGarage]

Thanks!!

Great video, love to see this stuff. Got a new subscriber

[@TommyLGarage]

Thank you and welcome to the family !

[@khalid749]

Great vid, dude. Ive a turbo but I imagine the priciples are the same.

[@TommyLGarage]

Thanks! Yes should be similar

[@Goelmoel]

Great video. Closing in on a 991.1 with 70K miles. Curious what I should expect on annual maintenance costs?

[@TommyLGarage]

Should be cheap. Gas and oil changes

[@RichmondTerminal]

Great work! Subscribed. I have a 992 T coming next year and am trying to figure out what I will be able to do myself as P-Car maintenance at the dealer is expensive for the sake of being expensive.

[@TommyLGarage]

Congratulations on the T! And yes you’ll be able to do all maintenance. It’s super easy.

[@abhinavjain4682]

Great detailed video! Have you considered the DS 3.12s yet? I absolutely loved them last year. Believe it or not, absolutely zero squealing on the streets.

[@TommyLGarage]

So these might be 3.12 actually. I bought them new but from a private person and I think they are those. Either way - I tested them and they are the best brake pads I’ve ever tried.

[@albertflecha150]

While still a pain, it looks easier to work on than the Cayman was. The oil change is a massive pain in the rear on the Cayman.

[@TommyLGarage]

I agree!!

[@rdadams7507]

With regard to collecting the oil, all you had to do was unscrew the drain cap on the container to let air in and the oil would have started flowing into it.

[@TommyLGarage]

Tried it. Didn’t work. It was clogged with grass

[@The1miz]

hey Tommy I have the quikjack I was quoted 350 to change out my spark plugs and my 887 just hit 100k runs good as new also I had them changed at 60k

[@TommyLGarage]

Seems like a great deal!!!

[@kenwhite7076]

I like how you work good job......Ken

[@The1miz]

I watched the video very helpful but why didn't you show how to get the coils and spark plugs off in the back any help would be appreciated thank you

[@TommyLGarage]

It’s easy. Pop off and slide out.

[@a.c.e.7568]

9:35 As for the spark plugs, so glad I own a 991.1 instead.

[@TommyLGarage]

Definitely easier on a 991.1

[@phileas816]

Excellent video, your best I have seen so far. You're really brave, full respect! Second, nicely done and very informative. Thanks for this! PS: can you actually put injector cleaner in a Porsche? That's an additive right? The user manual says "No additive allowed".

[@TommyLGarage]

Thanks! And yes I’ve been running injector cleaners without issues.

[@GarthGoldberg]

Nice brief video, tightly edited. But those brake pads were barely worn. I would have left them. Same with the spark plugs. I think I would have inspected and reinstalled. They're good for at least 40,000 miles, if not 60 or 80,000. K & N filters don't work as well as stock paper filters.

[@TommyLGarage]

Thank you I appreciate the feedback. I replaced the brake pads for Traxxax specific ones. And regarding spark plugs, Porsche recommends you replace them every four years regarding of the mileage to prevent seizing.

[@StarsAutoSport]

Great video. I need a Quick Jack!

[@TommyLGarage]

Get it!! Life saVer for sure

[@danrook5757]

I’m gonna wait for the electric porsche

[@titangrv]

There was some oil on the old spark plugs threads, is this OK? Or is there a gasket leak

[@TommyLGarage]

It’s not oil. It’s fuel. Perfectly normal

[@callmecue]

Never seen someone drill an oil catch pan. Especially while filling! Does yours not have a pressure release cap near the top edge?

[@TommyLGarage]

I left it outside and it clogged. My miss !

[@djsashimi]

two things. You shouldnt use straight dialectric grease. It needs to be dialectric / teflon compound BMW had it cheaper than porsche. Due to the heat from the proximity of the turbos, you need that type. Also you dont put it on the tip of the plug, you swab it on the inside 1 inch of the coil pack boot. That way the boot doesnt sieze on the porcelain. Also the bottom clamp of the turbo intake tubes are not to be reused. THis is all in the service manual

[@TommyLGarage]

Thanks for the feedback. I never have issues reusing clamps n

[@djsashimi]

@@TommyLGarage note the bottom one is different than the top one. Also note that there is blue loktight from the factory on the clamp screw. This is done to keep it from loosening up after many heat / cooling cycles. I guess in theory if you put new loktight on it it should work but porsche specs a new clamp just for that ONE clamp. I would keep an eye on it. I replaced mine with new and kept the old ones for a rainy day

[@rishabhsharma4079]

Great content, I feel like DIY on the 991 gen onwards is just unnecessarily difficult. For the coils, did you notice they had any vaccuum type pressure on them? I’m just wondering how you’d get those coils out after removing that screw if they were kind of suctioned into the hole a bit given that it’s such a tight area with no room to get your hands in there

[@TommyLGarage]

Thanks! So the coils had some vacuum to them but you just pull by the screw and they come right out.
