(Close them down to 10 thou, gives a little more lift than standard and is perfectly ok to do so before people start saying otherwise.) quote!!

what does 10 thou mean??? sorry for being dumb!

[vasi]

That'll be ten thousandsth of an inch

[The Matt]

about 0.25mm

[davexdavexdave]

thanks alot!!

[The Matt]

From the context I would assume you are reffering to valve clearance? (or tappet adjustment as it's often called). Yeah, 10 thou is deffo 0.010 inches.

[davexdavexdave]

yeah i am, is it ok for my car its a 998 standard??? and how do i measure 0.25mm???

[icklemini]

interesting original quote...hmmm..

anyhow - you'll need feeler gauges to set the valve clearances...

[vasi]

With feeler guages

[The Matt]

I would think it'll be Ok. (IIRC that quote was from someone who knows alot more about it than me). You adjust it with something called a feeler gauge (a thin strip of metal of a set thickness).

where do i get a feeler guage??

[vasi]

From any good tool shop

where do i get a feeler guage??

Most places that sell car parts and tools (Halfords being an example). While in there I would get a Haynes manual which goes into detail of how to adjust them. Better still, get a TMF CD, they have got loadsa info on them!
