Spark Plug Recess Depth

[m4tti]

Guys,
does anyone know how deep the plug recess is on the S6. My compression tester isnt the correct plug diameter, so will be ordering a new one.

Is the plug thread deeper than 300mm. Im not at home at the moment to check.

Cheers..

I think its around 150mm deep, possibly a little bit less.

on second thoughts, I was thinking of the plug caps, so allow for the plug length and clearing the top of the rocker cover then 250mm should be plenty I think.

Thanks Clive.

Im guessing the standard 300mm length compression tester will be fine then. You havent used one on yours by any chance have you?

Excellent. Should help me diagnose what's causing the smoke free oil consumption I have.
