First trip to the Diesel pump.
The ancient tint on the rear window has gone from bad to opaque. I'm going to need a new window, there's no way that crap will come off cleanly and not damage the defroster lines.
SO then I took her out for cruise on the highway... and promptly got stuck in traffic. :evil: 2:30, people, really?
I noticed the ride was very harsh, so I checked the tires... yep, 50 lbs of air will do that. Brought the tires down to a civilized setting, much better.
Tracks well, handles like I remember. Still not happy w/ the brakes, time for the 4-puck calipers and re-visit the BMW boost can later on.
On hard pulls EGT was around 780F, so plenty of breathing room, max boost was about 18psi, and at 60mph cruise when I finally found an open stretch of road, it was boosting around 7-8 psi.
Oil temps, however, went up to 240+ after a few hard pulls and high-speed runs... exactly what I'd heard would happen with this engine.
..which leads me to the next segment;
Oil System Upgrade
Consisting of an oil cooler mounted up front, a dual oil filter manifold, a 180-deg thermostat, a spin-on adapter, and many feet of reinforced hose.
With the dual filter rig, I am cloning AMSOIL's bypass filter setup, using their 2-micron bypass filter on one side, and a regular MANN filter on the other.
The bypass filter, by its restrictive nature, only filters maybe 10% of the oil in a given time period, but it does clean it all eventually, and removes even diesel soot particles.
I found a neat little spin-on size adapter on Ebay that allows use of the large (proprietary, maybe?) AMSOIL filter size with a regular type of filter mount... saving seveal hundred dollars over their full system price.
Mounted it on the rear upper crossbeam... the engine bay's getting crowded.
From below; no more sloppy oil changes!
The thermostat, mounted to the coolant reservoir bracket;
The spin-on adapter, replacing the original oil filter;
The front-mount oil cooler, showing the line routing behind the middle beam, just above the intercooler rad.
This is the hose I used, surplus hydraulic supply line from Ebay. Brutal stuff to cut, I used up 6 Dremel metal cutoff wheels making all the cuts for this install, the SS braid does a number on the discs. Teflon inner.
One original connector, and a failed attempt to cut it with tin snips
I followed the coolant lines up front for the hose routing. Here before finalizing and zip-ties;
The optimist in me says this is a nice clean install, and will control temps well. The pessimist in me says I've just added 24 new possible oil leaks. :lol:
After pre-filling the fore-aft lines with a pump, then idling the engine for a while, turns out I only need to tighten two of the brass fittings that are weeping a little.
A drive down the highway resulted in a solid 180 degrees.
