the angles as spelt out in the procedure in the manual weren't difficult to do by eye using a normal torque wrench. from memory they were simple angles like 90 degrees (right angle), 180 (opposite side of circle) or perhaps 120 (third of a circle). I doubt that small errors like, say, turning the wrench thru 115 degrees by eye instead of 120 degrees using a calibrated tool would matter. It might make the torque a ft-lb or so different. many torque wrenches would have this error anyway

It looks like several people have benefitted from Sparky's excellent write-up, so the community owes him a great debt of gratitude for taking the time to put it together. But of course, the collective experience of the brave souls who have undertaken this task has brought forth several constructive suggestions to make the procedure even more accurate and effective, from the sound of severl of the responses in this thread. So, it would seem to me the it would be very beneficial if a few of the people who have gone through the cam timing exercise were to update Sparky's write-up with their insights, resulting in a "grand unifying procedure" that could be consistently undertaken by anybody with the cajones to R & R their own 968 cylinder head. Heck, I may even take this on one of these days...

If anyone wants to expand the PDF procedure at start of this thread send me PM and I will send you the editable Word version.

(I would simply attach it to this post if I could figure out how [img]style_emoticons/<#EMO_DIR#>/unsure.gif[/img] )

I'm working on gathering up the various tools and fixturing to do this job. One thing that I'm lacking is the bent extension for the second dial gauge that is used to monitor the deflection of the intake lifter of cylinder #1 (does it matter which of the two lifters?). My cheapo dial gauges from Harbor freight just have short, straight plungers. Any idea where to get an extension like this, and how to mount it to my dial indicator? Sparky's write-say says "This gauge must be mounted so the vertical movement of the dial gauge is in line with the inlet valve stem axis." I'm having trouble picturing this, and why you need a bent dial gauge extension to achieve this. Is it because the cam lobe is in the way? Does anybody have a good picture of this second gauge with the bent extension doing its task? The picture in the manual is very unclear, and the one in Sparky's write-up appears to show a straight extension.



Finally, the procedure also calls for a straight extension long enough to reach the top of the piston through the spark plug hole. Dubai944 in another thread I recently started about finding <acronym title='top dead center'>TDC</acronym> with the engine on a stand sans flywheel says to use a dowel with a rounded end (where do I find something like that? All the ones I've ever seen have straight-cut ends). How would I attach the dowel to the dial indicator's plunger? Thanks; hopefully we'll all learn enough from the different people doing this job that we'll one day have a universal procedure, complete with a list of recommended tools, and where to find them.

Thanks, Flash, but I got hold of Lear35A, who's in Germany at the moment, and he sent my some nice photos which clear up a lot of my questions. I'll try to take measurements of my car tomorrow when it's light - I spent (wasted) the entire day trying to find the tools I need for the cam timing.

It is not allowed to say we wasted any time when we work on these cars (regardless of progress). Otherwise we will be committed to the looney bin.

"will be" committed? Too late for future tense here.



I'm taking the day off work, with my mission to find suitable tools that will work as extensions for my dial gauges. I'm not thrilled about the attachment pieces that came with mine, either. They're neither the magnetic, nor the screw-on type - they're hard to describe, but I'm not convinced they'll be stable enough for the job. We'll see, but if I have to search all over town for bases too, it will definitely slow me down some more.

I made my angled extension out of a piece of hanger and used a little RTV to hold it in place. Worked great. A little ghetto, but hey, sometimes you have to make your own...



I have a magnetic attachment for one of the two dials and solid metal block with a bunch of holes in it I got from Grizzly Tools. I can shoot you a couple of pics when I get home if you like.



How are you pressurizing the Variocam? I made a tool to pressurize the actuator out of another hose. Looks just like the factory tool.

Any reason that I can't seem to open the attachment DIY for camshaft timing, Is it me or somethine else?

There were data losses when the forum changes providers so it's probably related to that. if someone has it offline they can send to Flash and he can recreate the link.

Cloud, did you get my PM?

Yes, and I mailed you a copy of Sparky's procedure to the first email address you sent me. Did you not get it? If not, I'll try the second email address when I get home..

KRAG,



I emailed a copy to the second email address you gave me. Let me know if you didn't get it.

My apologies, I can open the first PDF file, but the second two are "not found". I'd also appreciate a copy if anyone has them saved aside.

i found and fixed the 4 images. still trying to figure out what the last 2 files were so i can replace them.

Anbody have thoughts or recommendations where to end-up within the +/- of the .39MM cam timing specs, .36MM or toward the .42 max. Whats helps or hinders. Is the range to small to matter?

How does belt stretch factor it?



Thoughts?
