tug 0 Posted April 13, 2005 I don't notice it really, but my friend mentioned it when he was following me the other day. Could this be down to the valve stem oil seals? I already have my doubts about them, but what else might it be? Many thanks! Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted April 13, 2005 Using much oil? Could be the guides, or the bores. Is he sure it was burnt oil he could smell and not sulphur from the cat? Any smoke? Quote Share this post Link to post Share on other sites
tug 0 Posted April 13, 2005 Uses a little oil, but nothing excessive. I only ever notice smoke if the engine's been on overrun shortly before. I'm waiting on parts arriving from the States for an engine rebuild, but was hoping I wouldn't have to go down the whole rebore & new pistons route... It wouldn't be sulphur from the cat, ain't got one! :) Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted April 13, 2005 Shine a torch into bores 1 and 6 and see if the piston crowns are oily (need to be at TDC) and also see if plugs 1 and 6 are oily. Smoking on overrun is usually a sign of guide wear, but can also be tired bores on the VR....and I know because I get the occasional puff after extended periods of downhill overrun, but my head was rebuilt last year.

tug 0 Posted April 13, 2005 Cheers Kev, I'll just have to wait until I start taking her to pieces to find out the extent of the damage! :) Quote Share this post Link to post Share on other sites
