Thanks for watching another long one. Maybe when it's all done I'll condense all the parts into one highlight reel with more entertainment, ha ha. If you aren't actually doing this it's long, I know.
Tom, another great video as always. Thanks for taking the time to go in depth on this. I’ve done this job several times and the only thing I would add to this is that it’s easier just to start with the intake rockers on #1 and #4 only. There’s really no need to put all the other rocker arms in until you’re done the valve timing. That way you don’t have to fight the tension on all the other valve springs. It allows you to adjust the cam where you want it much more easily. Slick idea on the O-ring tool and smart move on chamfering the rocker shaft bores. You’ve convinced me that I need to get the Stomski racing mechanical tensioner tool. I used to kluge it all together with a system of C clamps, but this is much more elegant!
Thanks, the problem I had before with only two rockers installed is that the cam moves too easily and slips too far. That's why I put all the rockers in and adjusted them first. In the end it just comes down to preference.
@@tomlipscomb2211Ha ha, like gold. Why did Porsche cheap out on these seals. They want their production cars to leak, but not their race cars? I thought all race cars leak?
I believe the stock 3.2 only has a flywheel bolt (with serrated flange), not a washer on the crank pulley. It has a higher torque spec too. I upgraded to this version when I changed my SC's crank pulley for the EFI conversion. The rocker shafts don't normally come with o-rings in those grooves do they? I kind of recall it was something fitted to RSR's, not the road cars, but it seems like a good upgrade to do. Great work as usual! No jokes about sucking, stroking or blowing yet ... 😉
@@GarageTimeAutoResto muchomasmejor. The original factory covers I had were warped so bad there was no gasket or RVT that would keep them from leaking. I did the same thing and went to aluminum covers - they are way better. Great update on the build, thank you!

Mt Rushmore of a vry concise explaining of porsche 911 timing wid vry mature & easy style
Thank you 😀
In my (recent) experience, it's easier with all rockers installed. This way the cam stays put when you pull the sprocket pin.
I agree. That's also why I did a rough valve adjustment before the cam timing too. This way the lobes have even pressure.

Great series! Cheers from Germany.
Cheers!
Nice chain ramp tool, good idea, that side is always a pain. I use castor based red rubber grease in the o rings
Yes, fab idea. The value of knackered rocker arms has rocketed. 😂

@@GarageTimeAutoRestowhen did you last see a 911 with a rusty rear valance? 😅
Never😀
Nice job. I never had to do the fine adjustment, but I did know about it. Nice to see how it's done. Love your dial indicator setup.
I'm going to revise my plate so I can do all the valve adjustments this way.
Great job. Easier than the XK engine which uses shims to adjust cam timing.
It's a clever system of adjustment for sure.

Thanks for your help. You are right those are referred to RSR rocker shaft seals.
I want to say that gasket remover works as fast as me with just the razón blade.
That's fair. That's a very old can of the good stuff that actually softens the gasket. Today's chemicals are much weaker.
@@GarageTimeAutoResto kinda like how paint strippers are crap now.
Thanks for your video it is very informative. Would you know what the cam setting is for a 2.7 stock magnesium engine?
Thanks, sorry I don't know the cam specs for that engine. I know it's not 1.25mm. I feel like it's 1.05mm, but please check the book.
ok thanks
Yes those are cool cars Peace out
would it be easier if the rockers for 1 and 4 was only installed?
My opinion is no, but there are many ways to do it. The cam can quickly move out of position if the other rockers aren't there to balance it.
@@GarageTimeAutoRestoThanks..Actully your right!..installing all rockers will help big time in the setting.
Are those the original magnesium valve covers or are the they aluminum covers from a 930 engine?
They are aluminum I believe and the Carrera engines came with lower turbo covers I think.
