I am completely flummoxed by this noise I am getting in my 2004 Turbo Cab. A couple nights ago while driving home with the top down, I noticed a rattle different from the normal sound of the motor and not accelerating/decelerating with changes in engine RPM. It occurred at 1800-2000 rpm and was most noticeable when decelerating in 2nd gear in my neighborhood at slow speeds (~20MPH)... with a helper on the throttle and the engine compartment open, it sounds like it is coming from the right side-top of the engine, around the Hydraulic reservoir. Putting a spanner/wrench on the component and up to the temple seems to have confirmed this as the source. I checked my manual and the Pentosin level (mid range on the HOT side of the dipstick at operating temp) I realize that Porsche recommends checking at 20C but I live in Texas now and that won't happen until November. Just out of curiosity I looked at the clutch reservoir up front and after removing the gooey trim cover, found it leaking (Seeping) from the recently replaced cap and appearing to be overfilled. The car has never really been operated in the 8 years I have had it in particularly high average temperatures, so I am hoping that the front is thermal expansion. Any thoughts on this matter are greatly appreciated... Loren? What Say You?? Thanks in advance,
My top quit on me so I got a whole lot of info from you guys and found my hydraulic tank was below MIN I followed the advice of this forum and added fluid to my top (it was below MIN). The cylinders now work well, but I think either the sync is off or I screwed something up messing with it before I finally checked the fluid. So here's what going on: 1) I start by mechanically opening up the 'hook latch' on the front of the top (top is in the half way closed position). 2) I continue to close it....it closes and latches. And then there is the back lid motor running but does NOT close the back lid...it times out 3) I push the open switch, it unlatches, top goes all the way down, side flaps fold up......motor starts for lid closure, but doesn't move....times out 4) I open top, side flaps open, top starts closing.....goes a foot from the windshield and stops (as does the hydraulic motor). 5) I notice that the 'hook' has not opened to receive the slot. 6) I manually open the 'hook', hit the switch and it closes and latches......but again, there is no closure of the rear cover. I do notice that the lever for the back cover (connected by the flexible shaft to the rear hook that draws the cover down) is not moving.....and therefore not hitting the microswitch). Is this a timing issue? Can the PST2 unit fix this.....or are there many more variables? Thing is, it was working fine and then one day it just 'stopped'....only 2 clicks...no motors Thanks guys
