How where the rubber bushings originally installed at the factory on the 914?

Tuesday 03/10/2026 | 1973 | 914 2.0 | Suspension

I am not confident that my measurements taken prior to bushing removal are accurate. When I reinstall the bushings with liquid soap (the commonly recommended procedure), how much "working time" will I have to make corrections as I install the control arms to the chassis? Are there different solutions (glycerin, ??) that I can use that will increase it?

When I'm driving with the top up and once the car is warmed up, I heard a subtle popping sound on the left side. Sounds like "puck". It's random vs. continous.

Thursday 03/05/2026 | 2005 | Boxster S | Other

The sound reminds me of a water dripping into a cup or pot. It's weird. When the top is down I do not hear it but that may be based on more outside noise.

968 Clutch Issue

Monday 03/02/2026 | 1992 | 968 | Transmission/Clutch

I have owned a '92 968 since '98 (and a '83 944 before that). The clutch has been getting progressively more grumpy as it gets older and can sometimes shudder quite badly from a start, especially when it is cold. The car now has 86,780 miles on it. And, I have replaced the engine mounts and transaxle mount recently, but those repairs did not help the clutch issue. More revs certainly help to get it moving, but I am thinking that it may be time to replace the clut ...

Purchased 2014 Cayman Base. When starting after sitting for a while, a couple of hours or overnight, when I put it in gear (automatic) the transmission initially slips. Once it grabs it seems to shift fine in second and beyond. It does this until it warms up and then the slipping in 1st goes away until I turn it off for a while. Any ideas?
