Def appreciate someone making videos and not trying to just make the bare minimum 10-15min video just to get a video out. Been following for a little while but recently Becoming one of my new favorite auto channels. Even appreciate the childish guy jokes and some cussing(we all do it). I like when people just being themselves and not putting on an act.

[@jacquescrusan9500]

Rob, just a note: A great way to clean the coolant channels is to run a 60/40 mix of distilled water/plain vinegar. Vinegar's great as a weak acid (both in chemical composition and its acidity) and as a lubricant for any seals in the system (specifically the water pump and o-rings). Simple process: Initial fill with 60/40 water/vinegar mix, run for 1 hr/100 miles in low load condition (whichever comes first). Drain, refill with pure distilled water, run for 5 minutes (to remove any residual vinegar from the system). Drain. Fill system with Coolant of choice. Edit: I have performed this on 4 seperate vehicles with relatively similar success. 1989 IROC Z, 2007 Tacoma 4.0l, 2009 Kawasaki ZX-6R, and 2014 Lexus IS250; just for reference.

Rob, I've been a rotary fan since early '70s and really enjoy your videos. Re. Hylomar, BMW motorcycles have specified that sealant for many years on a couple places in their bikes. Both places require a sealant between steel and aluminum surfaces (steel pinion seal holder threaded into the final drive housing which is aluminum), Hylomar is a non hardening sealant which maintains its seal where parts expand at different rates. If we used sealants that cure to solid it wouldn't stay sealed as long. Using Hylomar between steel and aluminum plates makes sense. Thanks for the great videos, and Isaiah is a star too.

[@ironbotta7282]

Don't forget that the tools that you are using on the CNC are also wearing down and that is a significant factor in why the holes for the dowels are getting tighter so make sure to take that into consideration when you go to machine the next irons

[@josht4923]

Props for that shot down the dowel holes 16:32 Trying to get a camera to focus down holes sucks 😂

this was incredible. really makes me wish you would do a full on, step by step, walkthrough guide on how to rebuild a 13b. something that an amateur that want's to rebuild their own rotary can put on and have real time commentary on every detail reasonably possible. could be quite the undertaking, but having a go to video by you to help hesitant rotary enthusiasts take that first dive would be insanely beneficial. even if it took years for you to be able to make it happen, i hope you will consider it. Thanks Rob!

[@curvs4me]

Unbelievable!!! I've seen a 100 rotary builds or more. Not once have I ever seen anyone say oh wow, let's try the FD thrust bearings and hardware. Awesome info, now everyone knows, much appreciated for demystifying the whole thing. It's not rocket science, just attention to detail and some improvement mods. If shops weren't charging unreal prices for rotary builds, they would still be everywhere. Way too many LS swapped FD and FCs out there. Viva la Dorito!!!

[@trevorreid5456]

Rob, check your machines coolant filters! machining iron is especially bad for plugging the filters and gunking up the entire coolant sump on machines as well. I remember after doing a run of 400 18" diameter piston liners made out of a solid round of Iron, the machines sumps were in really poor condition. Being the guy who had to pressure wash it after wasn't the most fun either 🤣

[@giopadilla]

Bro these daily 40+ minute videos are not something i want to get used to but I appreciate them in my inbox Rob. THANK YOU!!!

[@PaulChoix55]

If you got a freezer, freeze your dowels if they fit too tight at room temp. Just a friendly high school physics reminder! Loving the series so far :)

[@boostaddict_]

Housings are aluminum and I'm assuming the dowels are much harder, so the housings will expand measurably more with temperature. That fit should be fine for this engine. Then again I'm a first year engineering student who's never actually owned a rotary so I could be wrong lol.

[@ImConstantlyDrunk]

Ask your peers and find out if they share the opinion.

[@evanchi9460]

Correct, and aluminum will expand more than just about any steel they could possibly be using.

[@motoweenies4431]

Machinist/engineer, I'm just adding in, not really sure. But is it assumed all of the bolt centers grow in equal directions away from the center of the engine? Different amounts of material may cause unequal amounts of growth. Just one dowel/aluminum interface isolated, that fit is definitely fine. I'm just not sure of the bigger picture how they all interact together.

[@boostaddict_]

@@motoweenies4431 Yeah, the housings and irons will expand differently, but I think the iron will probably still expand more than the dowel. I don't think thermal expansion is a big enough factor to worry about tolerancing through the whole engine, if that were the case I'd think the housing would stretch and deform the plating inside where the apex seal rides. Some interesting engineering questions, might look into it sometime when I know more.

This is why Rob’s videos are my favorite automotive KZbin. I feel like I’m at a shop class. Most car KZbinrs are merely entertainment. Rob makes rotaries seem so simple it makes you wonder why they’re not everywhere.
