Yes I certainly owe you a ride! I'm not sure if I'll be in town for that weekend or not. We'll see--I'll keep you posted.

After cruising around town a bunch I took the car on its second maiden voyage but with the gf this time. A big loop trip spanning Quesnel, to Bend, OR, Astoria, OR, and back home. In total we drove 3700km! We picked a very hot week to be gone but there were thankfully many watery places we could get into the water. The highlights of the trip were hanging around Nelson, Rossland, Bend, and a 25 mile mountain bike ride along Mckenzie River at Mckenzie Bridge. And a quick visit with the Wolfman!

Prior to the trip, I had leaks on the ABS pump which only turned out to be fittings that were merely tight and not the required super tight. I also swapped the PS pump suction hose and flushed the PS (more on this later). I changed the oil from dino oil to a mix of Mobil 1 0W30 and 0W40 resulting in ~ 0w35. The car has been running great. I haven't even looked at the spark plugs yet. Ever! It has an intermittent wandering idle that indicates that the IACV needs a cleaning.

After dealing with 2 leaky racks on Golddust I was not willing to accept a failure on this RHD rack. The PS system was open to the elements when I got the shell so it was obviously dirty inside. Mostly clean looking ATF came out and some milky oil indicating water ingress. After getting the system together. I flushed a lot (5L ish) of ATF through the system to get the cleanliness back. I flew down the one weekend to do the PS system but didn't have the oil hose for the suction of the PS pump. I used a heater hose with plans to change it later once in Quesnel. Upon arrival In Quesnel, I examined the heater hose and it was gummy and appeared to be porous. I now pushed changing the hose out to the top of my priority list.

I sampled the oil after the drive up to Quesnel and did a particle count. I was sad to find it at 21/19/14. A rather dirty oil for a "critical" hydraulic system that I didn't want to endure rack leaks on. Most of the particles were non metal and I highly suspect many came out of my redneck hose. I changed out the hose and embarked on flushing round 2.

I flushed the system several times prior to the big road trip with new Mobil D/M fluid. I tested the new oil cleanliness at 15/13/11 (very clean!).
After 3700km, the system was now down to 19/17/12 (about 4x cleaner then before aka 1/4 the particles). FWIW, Eaton recommends a 20/18/15 at maximum for a system such as this <2000psi but cleaner is better. I've searched high and low for a functional filter to throw on the return line so that I can scrub the oil clean in service instead of just running some oil through and dumping it.

Particle count scales are base 2 so a 21/x/x has 4x the particles as 19/x/x or 64x the particles of the new oil from the bottle.

After 2 rounds of aggressive flushing, the oil is still not that clean. I'd like to see around a 17/15/13. After seeing how difficult it is to clean up this oil, it is no wonder that there is a big appetite for JDM powersteering pumps since the system all come from Japan open to the elements!

Enough nerd chat. Here are pics!

Google thought my route was too long so I broke it into 2 images.

Trip pics (in order). Some will probably recognize some locations.

We stopped to hear the noise of the wind turbines. Relatively noisy but SO cool I think. Around 1250 X more power than Silvia!

Our campsite in Mckenzie Bridge. A nice change from Eastern WA desert.

The McKenzie River trail up in Lava flows and takes you all the way down to old growth forests. We rode the 25mi in 105* heat. It was rather hot!

Forgot the fuel consumption details. 9.6 L/100km average over 3500km!

Nice trip. Did you rent bikes?

How was escaping the Cariboo with the fires and road closures? Also curious how far down were you still noticing the smoke?

Yep, we rented bikes. It was $80 for a bike, helmet and shuttle ride with a shower afterwards. A pretty good deal I think.

Thankfully Williams lake highway opened up right before the trip so we did only the Kamloops/24 detour both ways. I hate driving 16. I'll describe the places that had minimal smoke: Salmon Arm, Nelson, Bend, Oregon coast south of Astoria. The smoke was worst in Kamloops (47/10 bad) and pretty bad in Astoria even.
