[@stejskalmiro]

Hi Finn, cam timing question. Why to turn the engine to U6 and then to OT? There is no such a procedure in workshop manual for 5 chain engine. Thank you

[@ManinaGarage]

This video was a long time ago, I forget the details. This procedure came directly from the the top porsche engine builder on planet earth, Lee Jenkins. Better than any book 🫡. Thank you for watching 🤘😎

[@oilcoolman]

this is done so after the tensioner is installed you can still do some fine cam tuning to the timing , then bring the crank to top dead centre in the correct direction ( clockwise) . If you did it all at top dead centre and you found out your cam is too far around you might have a tendency to pull the crank back a bit to get the cam timing right.. if you do that at U6 that is okay as you can still bring it to TDC clockwise and see if everything worked.. if you did the fine tuning at TDC you have to go around another 720 degrees again to bring it to TDC clockwise to check. i hope i explained that well enough ,,

Dude you are without doubt the best and most reliable source of 996 info bar none, NewArt and his pal Grant come close but even they didn't mention the crank pulley U6 hole! With the help of your splendid videos I just finished replacing the variocam guides on my Boxster, I left the engine in the car, no point in making it too easy.

[@ManinaGarage]

Thats great news Peter! Nice work Duderama 🙌 Thank you for watching 🤘😎

[@peterdive3376]

@@ManinaGarage thank you for the 'thumbs up' you are most kind. Here's one you may have pondered on, but please forgive me if I am teaching Yoda. Why do the bank 1 and bank 2 guides wear the most on opposite sides? I think it is because the cams on each bank rotate in opposite directions (viewed from the sprocket end) So to advance the inlet cam the chain has to be pushed up on bank 2 and down on bank 1.

[@ManinaGarage]

[@CatzRuleZWorld]

Following along with this guide to put my 986 2.5L back together after replacing the variocam tensioner guides. The U6 thing is very strange. I can't find any info about it elsewhere. I see in your other comment that it's from Lee. The Porsche workshop manual I have doesn't say to do it that way. I'm sure either works fine in the end. Another interesting difference is that my primary chain sprocket is actually in two pieces; the part that sticks out and has the slot for the oil scavenge pump is a separate piece that hides the slots when you put it on. Other than those differences, the valvetrain is extremely similar to the 986.

[@ManinaGarage]

That’s very interesting to hear. I wonder why the primary chain sprocket is different?? Thank you for watching 🤘😎

[@ManinaGarage]

Hello Francesco 🙌, The Porsche 996 3.4 is really growing on me. Cars have always been of great interest to me, like most people I generally have just bought them, driven them and broken them for other people to fix. I really wanted to finally know once and for all the meaning and implication of the multitude of automotive terms I have heard over the years. Big ends, Cams, Blueprinting, Lifters etc, etc. This project is a baptism of FIRE 🤓. Despite the odd areas of stress it has been a very enjoyable journey. Without publishing the videos I could not have completed this work, if I had not had all the help and feedback from subscribers I would not have got this far. I love Cardiff 😍 as a kid I used to ride the Swansea Ferry to Ireland all the time. Thank you for watching 🤘😎

Far and away the best videos on the net for us 996 owners. I've watched the engine cam timing video and read your replies to Ricardo Baptista on starting the Cam Timing. A couple questions: It seems you later realized that the cam timing process should have started with the engine at TDC vs U6 - is that correct? Desperately want to avoid doing this wrong. Do I need to do the entire cam timing process for each bank, 1-3 & 4-6? Thank you so much. So excited with the prospect of getting this done and getting the 996 back on the road. Thx. Dean L

[@ManinaGarage]

Hello Dean, it’s a while since making that video. I know now that the video is 100% correct. You do need to start the entire process again to do bank 2. Good luck 🍀

i did notice that you went around some of the outside of the bolt holes... aren't you supposed to go inside of the bolt holes ? if you go around the outside of the bolt holes there is nothing stopping the oil traveling between the flanges up the bolt holes through the thread and out from underneath the bolt, as there is no sealant to stop it. ..just wondering

[@ManinaGarage]

@@oilcoolman This was a while ago for me, I don’t remember the details. One thing I do remember is the advice from Lee Jenkins at Hartech, he recommended putting sealant into the bolt holes to prevent the kind of leaking you are talking about. It may not be obvious in the video footage but I did do that in most cases. Thank you for watching & commenting!🤘😎

Hi. Thanks for another great video. I'm going to attempt a similar project on my 997.1 soon. May I ask did you find a manual or a detailed written guide anywhere for the rebuild? I'm not sure I'm confident I know enough yet to start without a big greasy book next to me. Your videos have been hugely helpful and you seem very knowledgeable. Was wondering where you learnt everything. Also have you put a new RMS in yet?

[@ManinaGarage]

Hello Stewart, I started with the Bentley manual, that does not go past the cylinder heads. Everything for that last few weeks has been sourced from online research, subscribers helping me plus Lee Jenkins at Hartech. There may be some books out there that tell you how to rebuild these engines, I don't know of any. Prior to this project I have never attempted anything like this, I don't have any skills or experience. I work in the music industry, I just wanted a project that forced me to learn about engines. Thank you for watching🤘😎

[@ManinaGarage]

Here’s a little addition to what I said earlier…….. There is “something” out there, subscribers have sent me all kinds of random photocopies and links to pretty official looking shop manuals. Some of them in German. Some I think are from Porsche techs who are sending me pieces of their manuals. If you send me an email I’ll share some of the links with you, it might help you find something for your car. [e-mail].

[@russelbarns1737]

[@aboyandhisdog]

I think you said about torquing the plugs: 30nm + 3. What do you mean by "+3"? And, how hard is it to remove the spark plug tubes? Do they just pull out with a finger in there or is a tool necessary? I'm doing this job soon and need any pointers I can get! Thanks, buddy!

[@ManinaGarage]

Hello Tom 🙌. Regarding the “+3” my understanding is you Torque the plug to 30nm. Then torque it another 3nm. That’s from the Bentley manual. Why that is different to just torquing it to 33Nm, I’m not sure?? The plug box said hand tight then 1/2-3/4 turn. For me, spark plug tubes came off with the cylinder head cover. They look like you technically could remove them individually as they are just being held by the o rings. Having said that, those o rings are holding them very tightly. You would need some tool that could expand into the tubes and hold them with enough friction to pull them out. A large long nose pliers that could open up into the hole might do the trick. If one is known to be damaged , drilling a hole in it could help you hook it out with something. Just my opinion, there may be some fancy way of getting them out easily. Good luck with your project 🍀

[@1ricardobaptista]

Hello, thanks for another great video, and in this one you accomplish a lot! Congrats! But I have one question: Are you sure that the timing should be made with the pin on U6 and not with the pin on the tearshape hole on the pulley ? And I'm not trying to be an smart..s here, just a genuine question and the reason for the question is that I saw many videos where all of then peolple used the teardrop shape hole on the pulley to establish the timing And that bring me to another question that I have, after seeing some timing videos they all say that on Bank 1 TDC the notch on the intake cam should face the cam cover and this notch on bank 2 face the block. I just assembled mine and on bank 1 TDC they are both facing the cam cover (or out) but the 2 half moons ( the big one and the small one ) on the exhaust cam are apposite to each other meaning that on bank 1 TDC the Porsche cam align tool fits on bank one and does not fit on bank 2 ( which seems to be correct ) Could you tell me how notches on the intake cam looks like? Thank you so much and sorry to use this media to ask this question for you

[@ManinaGarage]

Howdy Ricardo 🙌, I’m out and about right now, I will reread your question when I get home. The first part I think I can answer. I agree that the ultimate aim is to have the cams installed with the engine at Tdc. When I attempted to use the Bentley manual to do the timing, the instructions were along those lines (this was my first failed attempt and the reason I mention “redoing” bank 1). The method in the video was shown to me by Lee Jenkins at Hartech uk. I believe the difference is that by putting the cams in on U6, everything is settled by that little turn to tdc so you can then lock the primary chain sprocket in place at a slightly more accurate tdc. For the second part of your question I need to reread it with my notes in front of me. One thing to try is to turn the engine one more time back to tdc and see where the notches are. You are welcome to email me at [e-mail]. Thank you for watching 🤘😎

[@ManinaGarage]

Hello Ricardo, reading your second question again I am not sure why the notches would both be facing the same way. I would check that the dots on your cams (the ones that line up with the colored chain links) are close to center and on the top/outside of the cylinder head. Lmk 🙏

[@aboyandhisdog]

Nobody seems to make manuals anymore. I would love to have a manual for my 997 but Bentley, Haynes, Chilton don't make them for my car. I can't find anything for my car other than the Dempsey book "101 projects for your 911". Do you know of any manuals for a 997? Ever heard of such a thing? Thanks!

Good video - but that’s the wrong spark plug

[@miketdavies]

This video makes me think of all the times I've heard the question "did you have to split the case?" on repairs of friends' P-cars. We've seen the complexity of doing so, and yet this seems so simple* in comparison. I never want to hear the term "we have to split the case" on my car... * don't try this at home unless you're Finn or a certified Porsche tech!

[@ManinaGarage]

Your right, it does seem outlandish to take an engine OUT to work on it, though it is MUCH easier to work on if you do. Makes me less afraid of owning a Ferrari now............

[@miketdavies]

Well... a year later. Cracked head, and a bonus of signs of bore scoring discovered while investigating. Might be time to split the case!

[@FreshZ32]

You should NEVER use ARP lube on non ARP fasteners. Doing so will increase the torque/stretch put on the fastener and can cause fastener failures.

[@ManinaGarage]

Whats the difference between ARP Lube and other brands that would make that happen? Where are you getting these statistics? Thank you for watching! 🤘😎

[@FreshZ32]

@ManinaGarage I learned that two different ways. The 1st was from ARPs package insert that states why they supply the lubricant. In regards to using it on non ARP fasteners, I learned that the hard way, breaking threads in a block from using it on head bolts. I also had it confirmed by a local machine shop who tested it and told me that they saw a 40% increase in clamp load by using it.

[@ceelos4979]

I cant believe the timing is so much different than my Caymans engine

[@ManinaGarage]

That is VERY interesting 🧐. I was under the impression that the caymans had a very similar engine? I only think that because the Boxster engine is said to be almost identical to the 996 besides displacement. Perhaps the cayman was more of a redesign than I give it credit for. So much to learn……😳..Thank you for watching. 🤘😎
