Noticed today that my tappets are rattling a little bit so thought I would adjust them up, had a look in Haynes book of lies but there is no mention of which thickness feeler gauge to use, does anyone know?

I've got a new rocker gasket to fit at the same time, any other tips/advice?

Cheers, Harry

Had to do this in an emergency once. It's near as makes no difference the same thickness as a strongbow can :-D

Cheers guys, looks like I need some metric feeler gauges, only got imperial ones!

Strongbow I did use a John Smiths can a few years back in a similar emergency!

Might be worth checking if the valve caps are not worn out
You might have to take rocker shaft out to look properly

I dug out my imperial gauges the other day and it seems like they have got a tad damp and starting to orange in places, if I was to rub them with wire wool would that drastically change their thicknesses?

Valve caps should all be ok, they were new about a year ago -timing belt snapped

I've got to replace my rocker cover gasket soon and thought I might as well check the tappers while I've got the cover off. Is it routine to replace the caps at the same time?

Surely 7.874 thou would be more accurate James

I use 8 to 12 mm on my 300tdi, but check first that the rocker bar studs have not come loose like mine did. If this is so, I cured this by removing the studs completely, cleaning everything with carb cleaner & refitting studs upside down using locktite, as the threads in the head will have become weak, and are better the deeper they go. You will have to meddle a bit with washers to get a good fit for the tappet cover, as the short threads are now to the top, but it cured mine permanently. Before, I had been adjusting my tappets often, only to hear the bloody things a short while later (again). Then the rail broke because of the loose studs, and after limping back to base, did the above & no problems since.

Cheers guys, I will have a crack this week and let you know how it goes

In the end I bought some metric gauges due to the condition of my imperial ones
