Hi Guys
Anybody got any comments on using grease or any other compound on glow plug threads. I need to replace 1 glow plug on my 605, 5 cyl. 2.5l, Alloy head, in a W202. Ive used a product called Copaslip (in the UK) on outdoor threaded parts and it does stop them siezing up. Its a copper based "grease", but how would it do on an aluminium Cyl head ?. Any comments greatly appreciated.
