Blue shavings in engine bay, stalling in 1st
My 156 had to race a train the other day, pedal to floor for about 2 hours. Since getting home the car is struggling 0-2000 RPM, and stalling in 1st when the accelerator is touched (biting point and using clutch only it's fine). After 2 stalls, the car goes as normal, though sluggish under 2000 RPM. There's also a noticeable ticking / rattle in low revs.
It's booked in to see Graham Eddy on Monday but I've been having a nose around and spotted some blue shavings in engine (see attached pic). Graham's over the phone diagnosis is that this might be from the crank pulley. Thoughts? Anyone seen similar shavings?
Also noticed that the gearbox is leaking, looks like it may be coming from the driveshaft seal. Could this be causing the stalling / sluggishness?
I've disconnected the MAF and went for a drive and the car was still stalling. EGR was clean and functioning when I checked last month. There's also no error codes, so scratching my head a little.
