    Looking at buying a compression tester off ebay, but what size spark plugs are the saxos? Tried searching on google to no avail.

    Most of the kits have about 3-4 different adapters, i think saxos are 12 i can't remember. With mine i just tried them till i found one that fitted

    That site states 14mm thread size.

    I found out here... http://cgi.ebay.co.uk/COMPRESSION-TE...item27b432f0cf

    That the automotive one is for 16mm and 21mm spark plugs. So surely that wouldnt work? I dont really know

    16 and 21 mm aren't the thread sizes, thats socket size to take the plugs out

    mmmm and how do you propose to seal your lips round a hole thats recessesd like most engines? sorry but thats a daft idea
