Sometime in 2000 they changed the threads on the base of the advance mechanism to left handed.
Leading evidence: 'Replace threads' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace threads' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

I also ended up using a threaded rod, fortunately mine was older and standard threads - but actually I ended up bending the aluminum flange on the chain ramp..

Suggestion
There is not a way I am aware of testing the actuator unless you have it installed in the car running, and use the PST2 variocam activation test at warm idle you should hear the engine compensate for the cam advance.
Test of the variocam solenoid, is it possible just

Suggestion · Original poster
I didn't use a PST2 prior to test of the variocam solenoid, is it possible just to hook up a 12v source and see of the solenoid works or not?

If you have the actuator on the bench, you can tap the reverse thread with a standard 5mx.7 tap and use 5mx.7 all thread with a nut on top for an easy way around!

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Question (1). Does anyone know the thread size and the length of the rod needed to tighten down the it is call the Porsche 9632 tool. It is used to release the tension on the cam shaft tensioner.
Question (2). I didn't use a PST2 prior to test of the variocam solenoid, is it possible just to hook up a 12v source and see of the solenoid works or not?
Thanks
#2. Yes, if the engine 'was' still running in the car. With the car idling, you can hook up a bypass to the solenoid and power it remotely. or simply hook up a Durametric tool.
Engine is out as you can see from the picture, it is one of the things that I forgot to do. I was thinking just to hook up a 12v source and listen for the clicking.
The thread is 5mm .8 pitch. On a 99 it should be right handed. Sometime in 2000 they changed the threads on the base of the advance mechanism to left handed. You can get a piece of brass rod at the hardware store and a die at NAPA and make the tool yourself. You also need a couple of nuts for it. If it turns out to be left-handed threads in the base let me know. The left handed die is very difficult to find but I have one and can make a rod (or 2) for you. Here are a few pictures for your reference.
Dharn,
I have to say thanks for the use of the forum to get your problems solved. I"m doing the same work on my 2000 C2 and encountering the same issues (alternator bolt, etc.)
I'm having a heck of a time finding a left handed die even at napa!
You won't find a left handed one at NAPA. It took me forever to find an affordable one when I needed it. But look what I just found on eBay

Here is another source but more expensive and a min. $25 order.

I used zip ties (thanks Wayne @ Pelican!!!). Just thread them through the bottom below the chain guide and chain and then compressed by hand and then cinched up the tie wrap over the top of the chain.
You could also try threading a tie wrap through the holes that you use the threaded compression tool in.
Compress down in the center of the chain over the middle of the cam piston by hand (requires quite a bit of force), then cinch up the tie wrap so it relieves the tension.
I also ended up using a threaded rod, fortunately mine was older and standard threads - but actually I ended up bending the aluminum flange on the chain ramp.. which made me nervous, so resorted to just using the tie wraps instead. The key is to compress the piston first, then hold it in place with the screw or zip ties. I recommend a good high quality hard grade threaded rod, not the cheap hardware.
As for testing the solenoid, since you are in that far, just unscrew it from the actuator (two screws).
Then apply voltage to the two terminals on the cable via a 9v or 12 v battery. The piston should come out about 1/8" of an inch.
There is not a way I am aware of testing the actuator unless you have it installed in the car running, and use the PST2 variocam activation test at warm idle you should hear the engine compensate for the cam advance.
You can get a M5x.80 LH threaded rod and nuts from Belmetric

These are great folks with good service. They also cary a wide assortment of metric hoses, fasteners and clamps etc.
If you have the actuator on the bench, you can tap the reverse thread with a standard 5mx.7 tap and use 5mx.7 all thread with a nut on top for an easy way around!
Cheers,
Chris
so after this thread lays dorment for 2.5 yrs this may be a work around but how do u properly remove it from the engine if u dont compress it. It cost less the $20 to do it right so y risk it?
