Yes and no. The majority of damage was caused by high levels of sulphur in fuel (particualry in the north of the UK) in the late 1990's. Problem is once the damage is done, that's it.Does the problam not eminate form fuel that had high levels of sulphur, basicly bad batches??
It is a massive worry/talking point about the bmw engines. It seems a lot of people dont know about the problem before buying them and are very worried when they do reading on it.... They have been a massive amount of failures with nikasil engines but many still soldier on. It was a bigger problem in america from what i can tell, due to the higher sulphur content in the fuel. But really i'd want the alusil liners in my engine for piece of mind, but the nikasil engines are still around and the chances are, if they are fine today, then they will be fine tomorrow, as this problem was rectified years ago....:thumbsupIn the tuning world a those blocks wold be well recived, they offer good resistance to scoring, excelent seal to rings, low resistance thus low power loss but are prown to glazing easily if the fueling is lean or you drive like an old lady all the time, especialy from new! Fueling is critical for all engines long life but more so coated bores.
I didnt realise some BMW blocks where nicasil.
You will have to look from underneath :thumbsupMine has 108000 on the clock and runs fine.
I'm not to worried about just wondered what symptoms to look out for.
I've tried to look at the n/s of the block but am unable to see anything like the brass nut or the ordinary casting as there is to much pipe work in the way.
