Hy guys,opinions appreciated...

My GTI is stock-ish when it comes to the engine 1991 no EGR no CAT. straight exhaust 2" with middle and rear muffler and K&N Swift air filter.

... so today was driving to work as usual... sunny day, engine warm,checked oil yesterday, temp fine... and as usual when the engine is warm enough I like the sound that it makes around 5000 :)
so I was in 4th gear passing few cars and in distance I saw a car in my lane (European roads only one lane in each direction) so I went from 4th to 3rd gear with little throttle in between when suddenly I saw in my rear view mirror a blue cloud, I instinctively let go of the throttle and it stopped smoking, usually smokes very little(when in high rpms) ,when driven normally nothing.

As if it was clogged and suddenly got to breathe... but I drive this car on a daily basis and it is impossible for it to be congested. :) (i think)


Like a a month ago I started filling my car with "premium" gas (ECTO Eurosuper) which guarantees 95 octanes (other Eurosupers that say 95 are more like 85 octanes)
and while I was driving on the free way in 3rd gear and shifted (@7500) to 4th it made a very very loud ̣"POP" and im sure it threw fire, not once but twice that same evening...
Iam aware that this is considered "normal"... I know my GTI is more on the rich side when it comes to fuel/air mixture so I reckoned the new gas I poured really has more octanes and is throwing some of them out unprocessed... Was actually happy it did that because only REALLY tuned cars do things like this...
but after this today Im worried... so if somebody can give me a idea.

So my question is, is it possible that "stronger" fuel is causing problems ?
I understand that blue smoke is from oil that got into chamber (cylinder), so are my piston rings fried ?
If it was head gasket I would lose water , right ? ;)

I changed the cam bearings 2 years ago,same time as the water pump...
I do have a drooly distributor, besides that all is fine... (sometimes hydrolifters make a clicking sound, and I was going to overhaul the engine, now maybe sooner than I expected... :) )
I drive it for three years without remorse never had any problems...

Cam bearings? We don't have any suzuki engines in the USA that use cam bearings.
Blue smoke to me is running rich.
