Cam timing has to be the most difficult process in any rebuild. I don't see many others getting as deep into the engine rebuild as you have...kudos for your tenacity and mechanical abilities!!
Thanks thanks thanks a lot! I finally understood how to do it (for now😅) thanks to your explanation and attempts. Really grateful! Waiting to hear it roaring...
Make sure to prime those Carrera tensioners before installing many a build has had jumped timing with a fresh start on those. There is a good write up on the pelican forums.
@@HomeBuiltByJeff Jeff you are one of the few that don't go in to total geek speak, trying to look like a genius at the same time as putting people down, Benny, Al, Woody, Marty & Moog are all the same they and you talk to the masses as human, it is refreshing to see and hear as we learn something from watching rather than turn off and miss out on the fun education and enjoyment of seeing you turn a car most would see only fit for crushing in to a fully restored thing of beauty.
Thanks mate. I am not an expert, so that probably helps. I try to explain things in the way that I have managed to understand it. Glad it comes across well.
Jeff, I notice that you used the tension wrench to undo the bolt holding the cam on while you were setting the timing. As far as I'm aware, that is a big no no. Tension wrenches, being precision instruments, aren't ment to be used in reverse, that is, undo what you are tensioning
5.02 does seem like a lot .. this the right number? Did you recheck cam timing after installing Carrera tensioners? If cams too advanced, could explain sluggish performance.
Hey Jeff. Did you take the firing order into consideration? From what I have seen in this video it is possible to time the engine in the way that piston 1 and 4 fire at the same time. But I guess they should be one crank revolution out!? Keep up the good work!
@@HomeBuiltByJeff I used the clamp option and then set the timing. When I installed the chain tensioners I found the timing had changed. Maybe something that I did but I was glad I checked. There was plenty of pressure in my tensioners, as I needed to use a vice to compress it, in order to install them.
Interesting. I am not an expert, but I am following the advice of those I trust. I may just quickly check it again with the tensioners, as it is pretty easy at this stage.
Of course the cam timing would change if the oil fed tensioners don’t have oil pressure to them, and the chains are loose,so why would you try to check the cam timing with the oil fed tensioners installed?
I can sort of picture what you are talking about, but it wouldn't work. How would it attach to the sprocket. Remember that it needs to be held at the exact angle down to 0.1 of a degree, and even with the pin in it there is movement.
Hey Jeff, the Devil's in the detail, best to take the good advice of experienced Porsche engine builders and do it once, do it right, better safe than sorry, eh!
Why do you say the dreaded cam timing?. The cams should have had a timing mark, if not, they should have been punch marked before you put them in. You have the proper setup, stomski fixture and digital dial indicator, so you’ve got it easy, compared to most people.
Man I look forward to hearing you start this engine.
Haha, you and me both!
12:00 - 12:20 is a wonderfully accidental Mighty Car Mods style "clean/dirty" joke.
I noticed the S&M reference at 4:48. 😬
Yup! 5 tries in 3 different holes...

Well done Jeff this series was worth the wait. Very unconventional engine. Cant wait to see it in the porsche and "moving forward".
I agree. I love the videos to come in. Love the explanations. Easy going and laid back.. Thanks you two..
Thanks thanks thanks a lot! I finally understood how to do it (for now😅) thanks to your explanation and attempts. Really grateful! Waiting to hear it roaring...
Mate, so happy for yo. Followed you since you began. Now to pick a tee!
"Took me 5 tries in 3 different holes" - men with troubles since dinosaurs
@Shin Sho It's a sex joke
Fiddly procedure - well done. Helps a lot with the proper tooling too
Looking forward to see it in the engine bay.
Keep it up !

I'll watch when I get home 22:40 today, BRB
Well done and you managed to explain without talking Mechanic,
Thanks mate.

@@HomeBuiltByJeff You Ace it.
Like how you took the time to make sure the timing was exact and not acceptable with even a 0.1 discrepancy
Jeff, I notice that you used the tension wrench to undo the bolt holding the cam on while you were setting the timing.
As far as I'm aware, that is a big no no. Tension wrenches, being precision instruments, aren't ment to be used in reverse,
that is, undo what you are tensioning
Big milestone! Exciting👍
Absolutely! The hard part is done.

Keep up the good work!
Definitely. Just need to ensure that each side opens one revolution apart ;)
Do you use loctite on those bolts to type
Nope. Just a whole lot of torque!
@@HomeBuiltByJeff looking forward to hearing it run appreciate the little info
@@HomeBuiltByJeff I have a 1983 Porsche 911 SC I did a lot of free store to it but never touch the engine only had 38000 on it
Is it worth rechecking the cam timing again after you have changed over to the correct oil fed tensioners?
The timing is locked, and the issue is that the tensioners are not tight enough if the engine is not pressurising them with oil.

For the sake of setting up the dial indicator again, it can't hurt. 👍
Of course the cam timing would change if the oil fed tensioners don’t have oil pressure to them, and the chains are loose,so why would you try to check the cam timing with the oil fed tensioners installed?
Hi Jeff, just curious what camera/s and lens do you use?
Canon 70D with the 18-135mm STM lense.
I have never done this but why wouldn’t you just make a plate to bolt into the cam cover bolts to lock in the cam socket so it doesn’t move.

Hacksaw is all you need...
If at first you don't succeed try try try try again.....those specialist tools made it much easier than it would have been
I think on balance when I buy my 911 I will steal enough money to be able to pay someone else to build the engine...

If that oil cooler is all the engine has it won’t be enough.
It also has the front mount ;)
Does that car have the front serpentine cooler?
