kcw 1 Posted October 1, 2007 Report Share Posted October 1, 2007 AwriteI've just bought a '97 Highline a couple of days ago, and noticed a little blue smoke coming from the exhaust when coming off the throttle (mate driving behind confirmed blue smoke). I'm new to the VR6 game so dunno much about the engine so do you guys have any ideas on what it could be? Car has done 104k.Kenny Link to post Share on other sites
adam_christie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Smoke when coming off the throttle is almost certainly your valve stem seals and guides being a little worn out. There's no oil in water and vice versa is there? Also just check that your oil isn't over-filled. If it is, drain some out as excess oil will be picked up by the breather hoses on the top of the head, and into your inlet, which in turn will kill your CAT. Link to post Share on other sites
mannie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 vr6 do used oil ,at this mileage it's more likely to be valve oil stem seal(s) Link to post Share on other sites
kcw 1 Posted October 1, 2007 Author Report Share Posted October 1, 2007 Thanks guys, I actually had my suspicions about it being the valve stem oil seals. Is it gonna be a big job getting them replaced?Kenny Link to post Share on other sites
adam_christie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Yes. Well there are two ways of going about it.a) Get the head off, and get the tappets, valves and springs out. Get the valve guides replaced and subsequently the oil stem seals. Then re-assemble. Could cost a LOT as the head's off, and things like head gaskets, head bolts, and skimming of the head need to be paid for if necessary.Or Find someone with an air line and a fitting that goes into your spark plug hole. Take the inlet manifold off and cams out. Take out a spark plug and pressurise the cylinders with the air line and take the valve springs out without having to take the head off. This will allow you to change the seals, but not the guides. Might last 30,000 miles before they need doing again. When I did my 8V MK2 GTI this way it cost me £5! Link to post Share on other sites
kcw 1 Posted October 3, 2007 Author Report Share Posted October 3, 2007 I think I'd rather get the whole lot done properly, Has anybody had this done recently and could give me a price for it? Link to post Share on other sites
kcw 1 Posted October 5, 2007 Author Report Share Posted October 5, 2007 AwriteJust been out for a drive and it only seems to be smoking at low revs, between 1 and 2k generally. Also it seems to have developed a slight stutter/missfire at just about 1k, could the two be related? Kenny Link to post Share on other sites
xyber 1 Posted October 5, 2007 Report Share Posted October 5, 2007 Think id be tempted to do an oil change and replace the plugs and leads first and VAG COM it before anything else, might be lucky and save yourself a mint Link to post Share on other sites

Hellraiser 1 Posted October 6, 2007 Report Share Posted October 6, 2007 this http://www.pagershop.nl/product_info.php?products_id=605&osCsid=56aa1e5471ae2bb69cde414d9a87da6e is the direct link.Don't cost much either, Only 20€ for models after 1993 and about 40€ for models before that year because they still have the 4-pins connector.

kcw 1 Posted October 8, 2007 Author Report Share Posted October 8, 2007 I'm gonna have a look at the plugs later on today, if they look a bit iffy I'll replace them later in the week, got serviced in July so in theory they shouldnt need done. Link to post Share on other sites
