Before I change the plugs and leads on my 16v I need the correct size socket, after looking around there are lots of different sizes people are quoting. I’ve seen 16mm, 19mm, 21mm and some imperial socket sizes. can anyone help with this? thanks
16mm (5/8" imperial) but needs to be a shallow (thin walled) 3/8" drive socket. https://www.ebay.co.uk/itm/Sealey-A...791368&hash=item33cbf51c2d:g:aT8AAOSw3utY5g6C I remember 'a mate' getting a 1/2" drive socket stuck in the plug hole as it was thick walled, and had to take the inlet manifold and rocker cover off to get it out!
also depends on the rocker gasket, some are a bit chunkier when squished and poke out more into the plug holes. have done the very same on one of my 16v using a socket I never had any issues with before
tell you what its pretty annoying if you've only just built the engien back up after installing it in the car and last job is a new set of plugs
