@rafaellastracom64115 ай бұрын
I assume Porsche uses this adjustable system for cam timing, as opposed to one position, so that it is easy for someone to change the timing from standard to compensate for chain wear or custom specs. Is that correct?
@kavs9115 ай бұрын
Not so much chain wear but you can alter the cam timing to tune your power band.

First I must mention, I have enjoyed this series and will sub... BUT... I don't want like I am being picky, here... The torque specs you aimed for are wrong, on the cam nuts.... I thought maybe in video No. 5, that you would have rectified this, as you are in this video just setting timing and lash, and would do a final proper torque spec when done.... Any time you use a tool/attachment that will change the length of fulcrum point of a torque wrench, you need to add or subtract the length for proper required torque spec. Meaning, on one cam nut, you are under torqued by about 7 % of the 110 you were shooting for, and the other side, you were over torqued by about 7%... I speculate that things will be just fine for the life and performance of the engine, so I am not saying you have anything to worry about on those two location, due to their sizes.. but there was, I think in video number 1, you had a attachment in that one, (the connecting rod fasteners) that may have allowed the over torquing of 15 to 20 % the specs, yes, the yield stretch measured in the range to specs +/-, again, it was not stated that you adjusted for the torque wrench attachments additional length past the fulcrum's pivot point... Just a heads up. You may have already calculated for the fulcrum differences when using said attachment to the torque wrench, but it was not stated in the video... Again, Please note, I am not trying to sound overly critical here, but just for future reference, The small the fastener is, the critical the specs are to damage, stripping out of the threads, over yielding, or the fastener just simply coming loose.... Either way, This brought back many memories watching this engine rebuild, and I really enjoyed this...

Really not necessary to torque the cam nut fully to 110 ft ibs between each cam gear adjustment. Just tight enough to keep it all together. It is the pin that is keeping the cam gear from rotating, not the nut torque. Like wise it is not necessary to hold the cam from moving during the nut torque. Obviously it must be held to counteract the tightening but a little movement will not effect valve timing as again the pin is holding the relationship between cam and cam gear. I find it very time saving to set up gages on both #1 and #4 during this operation, then you can rotate the crank quickly and check both sides, back and forth against each other. Voila
@kavs9114 жыл бұрын
You'd be amazed how much play there is in the pin on the cam sprocket. I agree 110ft lbs is a lot but I don't want things to slip. Yes dual gauges would be the way to go!
@walterkucharski47905 жыл бұрын
To adjust valve lash use a dial indicator to set the clearance instead of a feeler gage. You will never go back. Cheers, great build.
@johnfalkenstine83774 жыл бұрын
On dealer flat rate which I had to work with, a dial indicator took far too much time. One got very proficient at setting the valves. The big problem was the early tensioners, which often frozen due to oil turning the seals into concrete and the oil could not circulate or flush once it was in the tensioner, so repairing one could could be a very smelly affair.

Amazing video series. I love watching engine builds like this. I’ve seen some Ferrari flat 12 engine builds and I think the cam timing is done in a similar way, except they have 4 cam sprockets! It’s so much more complicated than the Japanese engines I’m used to. Throw the cam sprockets on, timing belt, and you’re done. Like you I’m also “self taught” as far as auto mechanics go.

Indexing the cams was fun. I was with VW-Porsche in the mid to late 60's and had a 66 911 which I built into a very radical machine. When I was done with it, there were only two like it in the US. One in SoCal and one by Brumos. The double offset Crows wrench looked a bit different than the one that he had. RIP Peter. The people who worked on them back then were something else.

Flat rate agency work is the Bain of any thorough technician. The boss will accept running the job up to the maximum number of flat rate hours but at that point the technician is losing money on his labor. Beyond flat rate and the boss will have you in his office possibly to let you go. Only one tech one engine work gets attention such as this. OK is fine with the boss and sadly not OK work won't get you fired. A technical misstep gets the customer back in the shop and back on the clock. That is the business side of the techs job.
@TheObersalzburg4 жыл бұрын
Porsche's method for holding the sprocket to the cam for timing, with all its complexity of gears and pins, is really just dependent on the friction between the two for final accuracy. I realize this is a restoration and you're stuck with what you have, but thankfully modern OHC engines can achieve the same accuracy using procedures taking minutes not hours. You have the patience of a saint. BTW, being an old gearhead, I can see a way to make job easier but just as accurate, but when the purists saw me with a machinist's reamer and cut down drill bit doing surgery, they'd have a fit. ;>)

y when you take the heads off etc you need to check the valve lash again,not only that but after you install the engine and go thru a few heat cycles,I dont give dam what some folks say but I adjust the valves at TDC for every cylinder those cams have some weird valve timing, duration at 270 for the intake and 312 degrees is pretty wild, valve over lap helps cool the cylinders

yup you have to be fussy on engine building!! this shows some of that!! and yes you have to buy the best tools to make any engine builder look good!! bad quality tools = bad engine build!! it is funny how just a bit of off in the specs stacks up to large numbers off on the many parts!! and also knowing where to make things closer and larger on the specs... that is what makes a good engine tuner!! (precision builder) I work with the Kent motors as well as the Cosworth setups... tricky when you are building 980hp setups. just a smidge here and there makes 20 to 40 hp difference!! are you going to dyno this after the build? nice to have a break in run up!! before installing in the car!!

I don’t really see how you would do it differently? Great work anyways.. thanks for sharing.

There was tool marks on the cam pulley and was just wondering what exactly they could have done for it to be almost 180 degrees out.

I like your videos and your patience. Valve to piston clearance, just because the valves didn't hit the pistons doesn't mean the clearance is correct. Use soft valve springs made for testing and measure clearance with a dial gauge or use modelling clay on top of the pistons. Good idea to use degree wheel on crank and find true TDC. Cheers!

Hi Kav, I love the way you calmly talk about the valve timing. I’ve recently been building mine and found it very frustrating, going round and round in circles for hours, until I understood want was happening. Your video came in very helpful. I’m now on the valve clearances, and again I don’t understand why. After setting the rockers to 0.10, why then do you adjust the intake to 1.5 mm and 2.0 mm exhaust ? I have Wayne Dempsey’s book and a Porsche service manual which doesn’t mention valve overlap clearances ! Would you be kind enough to explain why the process needs to be done ?
@kavs9114 жыл бұрын
I depress the valves a further 1.5mm & 2mm to check that I have the minimum valve clearance required. I rotate the engine 720 degress and feel for any interference , then back them off again.
