Do Unleaded Heads need the same valve clearences?
Posted: Fri Mar 30, 2007 4:32 pm
Hi There
I have a 2.8i and it makes a light ticking that changes with engine speed. Numerous people told me to adjust the 'tappets' to sort this out. I took this to mean check and set the valves clearences (please correct me if I'm wrong).
I'm setting them this afternoon, as per haynes, but am a bit concerned that my car has been converted, by Vulcan, to run on unleaded. Do I still use the Haynes settings for clearences? 0.35mm/0.014" and 0.4mm/0.016" or do I need different ones. If so how do I find out what clearences I need?
I won't risk driving it until I get a response, I'll just set them for now and see what it sounds like at tickover.
Cheers for looking
Matt
