alfaholic 001 0 Report post Posted October 20, 2011 Is it normal for the twinny to smoke blue-ish white smoke on idle, just parked off and noticed, then when its driven over 2000rpm, smoke disappears Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted October 21, 2011 They don't so much stick but are held closed for too long by the spring whih is work ardened over its life in the engine, replacing this alone normally helps, but the parts have just taken me 6 months and 2 different agents to source.

Smaky 73 Report post Posted October 24, 2011 The worst then. Slow stop start, with running hot and short journeys, probably just worn out. Quote Share this post Link to post Share on other sites

Alfa156Melb 9 Report post Posted January 16, 2012 Yesterday I replaced the thermostat.. engine running at 90 deg now, and no smoke on idle Problem sorted. Quote Share this post Link to post Share on other sites
Alfa156Melb 9 Report post Posted January 29, 2012 The smokes back... It's such a small amount, I can't tell what colour it is.. but it's there.. Noticed it today.. was about 36 degrees, Air Con on full, left the car idling as I had the my other half and my 2 year old in the car.. I ran into a shop to get a drink... These breather valves you speak of Smaky.. you're talking about the PCV Valve yeah? If it is that causing the problem, where can I buy a new one?

2spark 6 Report post Posted January 29, 2012 Mine starts to smoke after a couple of seconds of starting her up then clears within 5mins of normal driving. Not much smoke but enough to see the odd wisp through the back window when idling. It's done 136000 so someone suggested valve seals? Smoke is white/greyish. No loss of coolant, engine temp smack on.

Smaky 73 Report post Posted February 2, 2012 That would possibly be the stem seals, especially of the heads never been off Sent from my iPhone using Tapatalk! Because I'm on tour! Quote Share this post Link to post Share on other sites
