Blue Smoke on Startup

Post by rod_dude on Fri Jan 02, 2015 11:14 am

OK if I leave the Uno for a few days it gives out a lot of blue smoke on startup. I have some receipts and it looks like the turbo was recently replaced, so I dont think its the turbo. Im suspecting the valve stem seals.

My question is, is replacing the valve stem seals something I should be taking on?

Should I just bung it into a garage to get it done? How much would that cost?

Thoughts anyone?

If its the valve stem seals then you will have to take the head off. Its a bit of a big job so might be best to give it to an engine builder.Have you checked the turbo for any play and oil in the boost pipes?

could be valve stem seals, could be piston rings, could still be the turbo,

I would take the head off yourself and take it to a engine recondition workshop and have them check it over,

take the inlet pipe off the turbo and check turbo for play,

Thanks guys - going to give it to someone to look at. Im also going see if the engine block is warped, I read on another site that this is often a symptom of a poor performing uno. I dont think mine is, but whilst Im at it this is an interesting read http://www.sfconline.org.uk/forum/topic.asp?TOPIC_ID=256.

Mine does the same... Brand new turbo last year so I'm guessing it's the valve stem seals too. Might have a go myself!
