gasoline in the 'oil ..........sigh
Discussion
dear all,
after track day in Mugello, gtr white smoke to a minimum.
in acceleration ,zero smoke!
in the workshop at home:
- Water level ok.
- but the engine oil level +2.5 kg!
-gasoline has gone in oil because it "seems" that 3 engine fuel injectors, were stuck open!
-I overhauled injectors, clean maf, filter and put new oil (the old oil, had only 3 track day ....)
someone said to have ruined the piston rings , because the engine has run with gasoline in the oil ....
I was advised to try to make 200km with new oil (castrol 10/60 in L98 engine), hoping that the engine will "resume" ..... otherwise I have to open the engine and replace the piston rings !
-There has never happened?
-which may be the reason?
I'm not a lucky person
Thanks to all those who answer me

the damage, if any, is proportionate to what you heard and when the incident happened...
Obviously you would be warned of the possibility of the bores in the affected cylinders being washed out, thus more wear, but that does not mean it is certain!
So, I would do a simple compression and leak-down test (plenty of youtube vids on this) on all cylinders first to assess if there are problems or not! ...
That way you don't guess....you KNOW! You could be lucky! Lucky-Lucky! (sorry...couldn't help myself)

I would suggest you invest in a borescope http://en.wikipedia.org/wiki/Borescope
Perfect tool to look inside your cylinders without having to open the engine

2.5kg of Gasoline is around 3.5 litres volume - around half that of an LS engine's oil capacity (dependant on cooing system), that seems a lot not to notice, surely the car was misfiring badly at that rate?,
I'd do a compression check, and if it doesn't look even across the cylinders, it may benefit changing out the oil with a mineral grade "breaking in oil" to try and re-bed the rings, though if the bores were that badly washed...........

thanks FC but in my LS 98 i have only max 4kg of oil with radiator.
scuse: what mean "braking oil"???
oil mineral??not sintetic?
i use castrol RS 10/60w
i don't uderstand.
gtr in acceleration not smoke and fast as before.
only at minimum smoke.only

Use to help bed in piston rings if there is a need.
Synthetic oil will not let the rings bed in as it is too good.
ciao
fortunately after 200km with new castrol edge 10/60 + Sintoflon my gtr stopped smoking at least!!!!
well I cleaned the maf and I went to imola!
senna day
fantastic day and my gtr very well.
I am very happy although I maf (hot wire) that continues to get dirty and have to clean it every track day: I installed kn conical filters and I think maybe the MAF dirty because they are in an oil bath.
What do you think?
thanks to all for the answers and the help of the last time.
