yes but thats not the real damage, seals are cheap and easily replaceable... (ok maybe not the cushion seal in the injector but thats usually the last one to go)
most people get lucky and do seals before they do real damage..
its when your on your new biofriendly seals that you'll find out what can get seriously damgaged...
gee! all this fuss for whats basically a dirty old ford motor!:twisted:
bet there's craploads of transits and 07's running on it in the uk...
cheers phil
i have ran 100% bio for the last 12 months clocking up 40 000ks in a 200 tdi with the fuel pump advanced and the turbo running 16psi and flogged the sh#* out of it more power no smoke and when i took the head off after drowning it in a river there was barely any soot in the cylinder head and the injectors look fine and the engine has done 320 000Quote:

yes we ran full old chip oil in ours too, but the 200tdi is neither a new engine let alone a common railQuote:

to desummate the previous summery of my post...
the killer is the injection pressure
the older the diesel (unless you get into unit injection like the TD5) the lower the pressure.
Biodiesel (and WVO) breaks down under extremes of heat and pressure and loses its lubricity (so does bad diesel)
if your injectors are pefectly clean then this isnt a problem but if you get any "crud" in the injectors (and Im talking crud with the dimensions of microns) then the loss of lubricity becomes a problem and the "crud" will deposit itself in the injector. Once it gets started it will attract more and more "crud" and eventually you get injector problems...
Higher pressure injectors have finer internal tolerances then lower pressure ones in an old school diesel like Fozzy the tolerances in the injectors are wide enough to do dounuts with road trains in and the pressure is low so for starters the fuel doesnt break down and any deposits wont clag the injector. In big reds modern common rails unit injected diesel youd be lucky to turn a monocycle and the pressures is up above the cracking pressure of the fuel so you'll get the deposits...
IMHO the TDI's and suzis are marginal but so long as your fuel is correctly filtered you should be laughing
IF I could get injectors for big red at $200 each ID run bio but at over $1100 each its not going to happen as you have to assume that if one injectors bad then they all are close to bad...
