I just started up my Cayman (2006 2.7, 38,000 miles) for the first time since mid December. It's been stood outside in the cold and the battery was very low so it wouldn't crank properly. I put it on charge for a couple of hours then it started up OK but it's making a "clacking" noise from the engine, sounds like a hydraulic follower that has failed to pump up. It was perfectly OK when I parked it up in my back yard back in December, I think it often makes a similar noise for a few seconds when it hasn't been started for several weeks but it usually goes away in a second or two but now it's doing it all the time. I tried revving it up a couple of times but to no avail, then I left it idling for 10 minutes to warm up properly, expecting the noise to quieten down but it's still the same.
Does anyone know if these engines do have hydraulic followers and if this might be the cause of the noise or might it be something more serious?
Thanks,
Martin
