when i start my car in the moring there is a lot of blue smoke, it smells as well the engine is ready for its first serive, will it stop after this or is it sumet serious, it goes after driving for a couple of mins its not the usual white smoke cause of the cold

thanks tom

You say first service due, have you just rebuilt/changed the engine?

its a freshly rebuilt mg 1275cc engine was a full rebuild

Including valve guides and seals?
These being worn, or missing, in the case of the seals is the normal cause of blue smoke at start up.

did it have a full rebore or just piston rings

full rebore and apperntly everything was replaced

Good engines don't smoke......... Why would a 'service' stop this ?? Blue smoke is oil burning - so somehow oil is getting into the combustion chambers. Could be running down the valve stems - but I doubt that's all that's wrong........ As ever - a compression check is useful.

il do a check 2moro

thanks tom

this is the engine http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0456102639

and i just realised i didnt retrque the head down at 1000 miles il do it asap

eBay description didn't say valves or guides done. My money would be on them.

not that i've ever seen or experienced your driving mr hotrodder... i'm just assuming from rumours , but have you been driving your freshly rebuilt engine nice and gently for the first 1500 or so miles? to allow everything to bed in? or have you been hooning around?

just a thought!

no i really have run it in cause it was a lot of money ! the rumors are probily true about the old engine

tom

well it stopped after tighening the cylinder head nuts, they were a bit lose

happy days

tom

Hope you also re-set the valve gaps. Can't see how this affects blue smoke - but as long as it's not doing it now.......

i asked the seller and he said there must have been oil leaking in to one of the cylinders and asked if i had tightened it down,

but it working now
