Great content. When installing the the cam chain covers, you use gasket only, no sealant? What are the signs that the fan needs to be replaced? And are some fans better than others? There are different fan sizes and configurations. For example, I think it was 74 thru 77 that had 5 blade fans.
That is correct Sealer should not be used. Gasket surfaces need to be clean, dry, and flat. When it comes to fans Porsche used a number of combinations of diameter and fan blade counts. Fan design is matched to engine design and purpose. The most common reason that I replace a fan is for either wear at the Sheave or broken blades. Kurt
Love the detailed and clear explanation of your work - could you also add torque specs - i am replacing cam chain tensioners and need the specs for the tensioner nut and the cover nuts - thanks
We have specific videos on our channel that are an actual lesson versus this one which is more record of work done. In our lesson videos I give all tightening torques as we go along as well as more detail about the specific job being done. You can find these under our rebuilding play lists Kurt
I use multiple Cerakote products depending on what parts I am applying the finish to. For some parts I the "H" series paints which are a bake on finish. I also use the "C" series products for items that are big and also see less mechanical wear and tear. Lastly on polished Aluminum or Magnesium I use their specific clear coat products for those products. Kurt
Ok I see. Is it two o-rings per retainer? I have a problem retainer on cylinder 5 that is loose…again. I think I need these seals, a new retainer, new hardware and a new bushing
If your rocker shaft continually comes loose in a short amount of time, then the cam box is most likely worn and may need to be replaced. There are two O-rings per shaft, and the O-rings are only to mitigate oil seepage. Kurt
Yeah that could be. This car sat for years and I got it going but it came loose. I think the same shaft was reused when it was tightened. It’s only that cylinder that has come loose. Is there a diameter spec on the can box bore for the retainer?
In a 964 3.6L with a higher compression engine sequential fuel injection and computer-controlled idle, intake plenum, and timing, they are great. In a 3.0L SC CIS car not so much. Kurt

It takes time to make it that way but it is worth it. S.
Excellent video Kurt. You and Sara do excellent work.
Thanks. S.
Great skill and building tips, very thorough engine build, finished product is a work of art , video production also top quality.
Glad you liked it!
it's a delight to see you work and showing the magic to us 😇
your welcome and thanks
Kurt
your videos are very professional, rich and interesting, !!!thanks, I don't miss them!! ❤
Nice to hear, S.
Can't wait to see it! Wish you the best!
Thank you guys.😊
Our pleasure!
Kurt
Very interesting build. Great to see all the in-house machining and use of special tooling for set up and assembly .Nice Job throughout 😊
Glad you enjoyed it and thanks for watching.
Kurt
Great Job! The engine looks amazing!
Thank you very much!
Kurt
Porsche flat-six -modern technology from 1963! It is unbelievable how an excellent construction never ages.
Thanks for watching
Kurt
Looks brand spanking new.
Thanks,
Kurt
Just found your channel. Awesome!
Awesome! Thank you!

Which Cerakote product do you use for this please?

Kurt
@@klassikats I assumed it was C for engine tin? Any particular black you prefer? Thanks
On this one I used Glacier Black
Kurt
You mention updated o-rings when referring to the rocker shafts. What is updated about them?
The fact that Orings are now used as opposed to the original build not using O-Rings
Kurt
Ok I see. Is it two o-rings per retainer? I have a problem retainer on cylinder 5 that is loose…again. I think I need these seals, a new retainer, new hardware and a new bushing

nice job kurt do i detect an aussie accent?
Thanks
Kurt
All of this work and money just to put stock profile cams back in
The only way to go for a street driven stock engine.
Kurt
@@klassikats Even 964 cams aren't great for the street?
In a 964 3.6L with a higher compression engine sequential fuel injection and computer-controlled idle, intake plenum, and timing, they are great. In a 3.0L SC CIS car not so much.
Kurt
Still the case when you go to computer controlled ignition like CDI+?
