dis information? mis information?
Look, I know the oils main function is for lubrication of the discs in the cylinder. also for anti corrosion. there is very little movement, and the force Is substantial enough that I don't think that there is enough movement for the oil to damp out any vibrations. maybe, as the highlighted area says, in cases were its very loose, and about to come off, there is a lot of movement and the oil helps dampen out vibrations.
as you know,i have never used oil In the tensioner (just a little to keep it from rusting). no problems in 15 years of doing it this way.
I would have been more inclined to fill it up if all of it didn't fall out the oil seal side.
im not saying that its not needed... I just think everyone gets a little too lathered up about the oil and its real function.
calling them springs is a stretch too. they are bi-metallic wasters. they produce a lot of force and without any movement. for their to be damping, there should be some movement, right? seems like the fluid is for when things go wrong.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

but, i do like the notation, and gain much comfort that if you loose all the fluid, the tensioner performs just as its predecessor does, albeit without "damping". sounds like its some fine tuning feature, that comes into play in some cases where there is belt resonance, of if the belt is too loose, it can help from a tooth being skipped. I think at proper tension, there doesnt seem to be the force available to really move the tensioner piston in much of a distance.
Im on a roll.. im going to continue to see how long it lasts without oil. 14 years and counting!

Yes, without oil the tensioner functions the same as the pre-83 tensioners that were designed for the single-cam 16v engines. But as the engines got bigger and the cams multiplied, Porsche made some changes. Most of which you seem to deliberately avoid.
You have a nice motor, why not treat it to a S4+ tensioner and WP and a Gates belt, and assemble the tensioner properly so that it doesn't leak?
