Hydraulic tappets pumping up - does it do on when you hot start?
When was the last service?
How many miles on the car?

[andrewdunn]

hello mate,the car was last serviced nov 2004 due its 48k service nov 2005,no it only does it when it fires for the first time in a morning,like i say it only lasts for 10/15 seconds then goes off and you wont hear again,its a slow tick if that helps

Tappets.

What oil are you using?

A change of oil might do it.

...it's perfectly normal (TADT) if, as you say, the sound vanishes within a couple of minutes. Nothing to worry about.

well thats good news,by the way its on mobil 1 ,thanks

Phew, mine does that too, suspected it was just the hydraulic tappets, but nice to hear "TADT...Sir".

Incidentally, what oil is the preferred one for the water-cooled lumps? (as opposed to just what Porsche recommend in their handbooks)...any thoughts?

I've always used Millers fully synth in the Westfield (Vauxhall powered) and the Scoob, and have been pleased with it (well, neither have gone bang!...Vauxhall engine seems to live at 9000 quite happily without showing any unexpected signs of wear)....
