    Project Polar Bear: 2005 Suburban 2500

    Ah yes, the dreaded BMW problems which inevitably rear their head. Upon inspection of the bottom end with oil pan removed, the chain guides are fully intact. I am patiently waiting for the motor or trans to give out, as I have a bit of experience with engine swapping this platform. Here's a...

    Thanks! I'm trying to document everything as well as I can mostly for my own records and to get some traction on my youtube channel. I just picked up another project that was sitting for years, 2001 BMW 740iL. Much longer video on that one coming out soon.

    I have to admit, I cheated a bit - those wheel bearings were actually replaced last year. Branded as Timkens, but came in a Made in China box, so I have a feeling they were knockoffs as they didn't last a year. At least everything was antiseized well. Helps that it's a rust free truck too.

    Project Polar Bear: 2005 Suburban 2500

    Deleted the radiator end tank oil cooler, added the external air to oil cooler, and installed e-fans on the 2500. Had the PCM tuned by PCMofNC for the fans as well as a general performance 93 tune to wake it up. Slapped on some stock size 245 tires to replace the 265 A/Ts in an attempt to give...

    Project Polar Bear: 2005 Suburban 2500

    Got back from a weekend camping trip, about 120 miles round trip on mostly flat ground with some hills here and there. The terrain didn't really push the drivetrain the way I would have liked, but the oil temp didn't get above 205F on the few hills we encountered. I really would like a little...

    Glad you liked Niagara Falls! That's right in my neck of the woods. The weather here has been brutally hot and humid (by our standards).

    240F-265F?! Holy moly, that's wild. The trans in my truck has never seen above 175F using the radiator end tank cooler in series with the Trucool 40K, but then again my towing profile on gradients is much easier than yours. I'm not saying your experiment is invalid, but in the interest of...

    I can't imagine a giant T6 frame turbo being a good selection for a tow rig that needs response under 4K. Most of the time when towing I don't even rev it over 4500rpm. I've been eyeballing the 7675 or similar T4 frame. Thanks for the compliment!

    Did you mean external oil to air cooler? The air to water cooler would be the radiator itself. How big was your external cooler, and what were the conditions of your experiment? I ran one that was half this size, with no supplemental oil-to-water cooling, in a C5 Corvette on a road course in...

    A while back I installed the LTZ roof rack with multiple Z71 bars. In the back of the truck I carry a piece of plywood so I can throw it up there and have a good observation deck if I'm at the racetrack or planespotting. Took our first ever camping trip about 2 hours away. Everything worked...

    It sure is, it also has a turbo LQ4/4L80E. I build it a couple of years ago as a fun summer cruiser. https://ls1tech.com/forums/conversions-swaps/1954898-1984-jaguar-xj6-6-0-80e-turbo.html That is the plan! Other than fixing the clunking steering column and eventually refreshing the...

    Exterior needed freshening up, 20 years had taken its toll. D pillar covers before: After: Rear taillights before with odd clear coat peeling: I thought briefly about sanding and polishing the originals but new ones are so cheap that it's not worth the effort. Relocated...

    Whistling solved. A/C tensioner removed altogether and GMT900 stretch belt installed. Video coming once I edit the voiceover. Stock rear wheel width: Wow, I haven't seen these things in a long time...certainly never on a car I've personally owned before. 2" wheel spacers installed...

    Project Polar Bear: 2005 Suburban 2500

    I have been chasing a wicked loud whistle from the motor for a few weeks now. Since the whistle sounded so much like an air leak, part of my troubleshooting was to remove the intake and do intake manifold gaskets/valley gasket; while I was in there I also did the cam position sensor, oil...
