| Hmm
I had a similar problem on the 996 and when Nelly stripped it down at the 12K service he found a seized clutch pressure plate bearing and a snapped push rod as it goes through the casing, still workwed but when I lost pressure I just pumped it a few times and all worked nearly fine but seemed to free of if parked for a while which makes me think it was a sticking pushrod?
Poss caused by the split rubber?
Nelly will sort for certain when it gets there, worked for mine. |
