Hi there,
I've had a question from someone that I can't help with - he's got a 205 XS which runs on 4* petrol and was wondering if it's possible to convert it to unleaded and if so, how much would it cost and who does it?
Am I right in thinking that you could get the head from a later XS that runs on unleaded and use that? What else would be required?
If that's possible, it would be a good time to do it as his head gasket has just gone so the head needs to come off anyway!
Cheers, M
AFAIK and of the TU series engines can run on UL, its just a matter of tweaking the timing slightly (3 degrees I think, but I cant remember which way, will look for ya).
JAh yes, that does ring a bell (I'm sure it's in the Haynes manual addendum somewhere) - what I was wondering about though was will the valve seats suffer over time or are they sufficiently hardy enough to cope? - Anyone any experience either way?
Cheers, Matt
IIRC, it should be retarded 3 degrees (usually). Hey, that sounds like a weird band name. ;) I don't think valve seat wear is an issue on any TU engines, they're all new enough to be able to take unleaded.
Chris.
Agreed, on all three points. Stripped my TU1 after 50K running UL and valve seats were as normal i.e. a bit pitted but not much.
JThanks Chris & J - that's kind of what I was hoping to hear.
Cheers, Matt
