Hi. I'm in Baghdad, and since the e34 is probably the best popular car over here (other choices being some early-1990s toyota corona/super saloons; 84-87 passat; ex-police/taxi caprices), I'm driving one. Trying to collect more for the company, always.

I was wondering if anyone had any standard procedures for sand/heatproofing the e34. I've started to see some overheating issues on a 520i just in from germany, so i'm going to go through the standard checklist, replace the oil with local appropriate oil, etc.

We also have fuel problems over here, so I'm staying with the I6es. My goal is to somehow find a 535i in good condition, or at least stick with big-block I6, but 520i have been slightly more plentiful. If there are any good mods to the I6 to make it more tolerant of bad (dirty, high sulfur, low additive, low octane) fuel, that would be great.
