Most likely. I'll know Wednesday when it comes out of the dealer, hopefully fixed and not another faked out headgasket problem

I don't think I want to put anything that is not fully combustible into the combustion chamber.

In this pic, which color arrow is the supply of air (red), and the exit of air? The cylinder heads are aluminum. Looks like atomized meth will go through aluminum parts after the intake and just before the combustion chamber? What's the chance of that alcohol condensing and sitting on the aluminum intake track to the combustion chamber? With such high heat, not sure that any highly flamable liquid is going to form droplets on the aluminum, and the water is going to evaporate.

If you want to be 100% sure, I think you need a couple of different types of engineers.

ok, sold! really nice crosssection of the engine, have any more of these?

It came from the pdf documents on the n54 in this thread:

Defintley save those docs. They are a great read.

It seems that same topic arises in e90post as evom, but only 2-3 years later.

There was this discussion over at evo forum, but vendors have found that even after years of methanol use, no aluminum components showed any sign of damage from meth when the engines were taken apart.

Meth does react with aluminum but a tiny amount of meth sprayed in an atomized fashion in the intake track that vaporizes immediately is not enough to react considerably. Even if it does, it is so microscopic, that even after years of continuous meth use, it can't be detected by naked eye.

Bottom line: stop worrying and start spraying...Although I am not a fan of meth and rather convert to e85 for BIG power.

You can see my oil analysis in this thread and although there was no more aluminum wear, there was more lead wear. But then again, maybe it was due to changing oils.
The good thing is that I didn't see any high wear from aluminum.

Yeah, saw that, nice..where does that lead come from though?

The main source from lead is bearings. I ran my car pretty hard at Famoso and Sac and Blackstone said that the extra bearing wear could have been because of the track time.
This is what will be interesting to see with the next oil change.
If the lead is still elevated then maybe it is the meth.

When is your next oil change?
