Hi
New to all this so apologies if been asked before, I've searched the forum but couldn't find a definitive answer. I picked up a non runner S3a at the weekend and have managed to get it running and moving. I believe the engine is a Pinto 2ltr 205 block from 1987. there is a stamp that looks like "I" to the left of plug #4.
HAs anyone got any idea what the I stands for, is it leaded? if so does it need an additive? what's the best to use and how often?
Ive not had the chance to take the head off to see what shape the ports are, as I want to take it for an mot to get a list of what needs to be down to get it back on the road, then ill have plenty to do in the winter..
Thanks for your time!
