Hi Guys,
Something strange happened just now with my car, it normally runs fantastic... Mk1 auto.
Was driving along and came to a stop at some lights close to home and noticed that the idle speeds was a touch higher than normal, thought nothing of it as the temp was a fraction higher than normal... just a touch.... at the next set of lights it idle speeds was a touch higher again... so I tried pushing the choke in to no effect.... 1.5kms of winding suburban roads and roundabouts and I arrive home. Stopped and put in reverse (engine revs slightly higher again and a cluck into gear), start up our slightly inclined drive and as I have started, about 90% through my reverse turn, a puff blue smoke came out the exhaust... completed reverse and put into park... no more smoke other than that one puff (it never, ever smokes, engine was rebuilt and have done about 30k Kms only) revs are higher than normal and lifting the bonnet and playing with the accelerator/choke makes no difference... powered it of and let it sit for 5mins.... started again first kick but revs are still high....
I would greatly appreciate any thoughts as the car is my daily commute to work. Somehow my brain is saying to check the oil in the carbie? Am I on the right track with that??
Thanks in advance.

found it and it’s an easy fix as I have a spare... the rubber diaphragm in the pcv valve had a hole in it!! I was always suspicious of this one as it is much thinner than the original one that was in the car.
