I was a teenager when rotary engines first came out. They had a reputation for not running well though when the engine ran, it was very powerful. How would you describe how they are more reliable now compared to before and compared to a high powered piston engine? I plan to use a 3 rotor Wankel engine with my airplane that I haven't built yet. Would you be more comfortable for safety reasons with a conventional engine or a rotary engine at 10,000 feet in the air?

10:57 side seals*
Rick Cooper
Rick Cooper پیش 6 ماه
to pop side seals out that are stuck air with a blowgun i made a needle type nozzle that i made from a basketball inflating needle put a 90 bend on it to where it just sets in the area where the apex seal ends are after removal that way can blow under the side seals and it tends to lift them especially after you have done the bucket of diesel / trans fluid trick I mentioned before
Rick Cooper
Rick Cooper پیش 6 ماه
I will give you a piece of advise that will save you headaches from the chemical sprays take a home depot 5 gallon bucket and lid fill it a bit over 1/2 full with diesel add 1 gallon of universal transmission fluid to it and let your parts you want to clean or have stuck seals and such set in that for a week then pull them out and well any nastiness on them just literally wipes off and usually the seals and such for rotary engines loosen up and come out with ease have done this many times and then you put lid back on the bucket and put it in the corner with old fluid still in it ready for next time you need it got to remember the K.I.S.S method LOL.

Would really love to see the AWD RX7 On Fitment Industries' Driver to Driver series lol, here's how I imagine it going down: "How much did you spend on your rotary STI? And it hasn't run in years? You could have had like 121,532 crunchy tacos From Taco Bell for that. So you spent that much money on a car that has really never even started. You could've bought like 3 more RX7s for that dude"

I would check to see if the apex seal grooves are still straight. Those dents might have pulled them out unevenly. Insert old Apex seal and appropriate shim and lightly tape with a hammer. Rotors are very malleable

Can we get a bit more structure from now on? I know it’s not really how you do things but you mentioned for the 3 rotor your goal is to show that you can do it for a few thousand dollars. I think it’s really a cool thing and it deserves more attention because not many (including me) want to even consider living with a rotary cause we don’t know about it and it’s expensive. Would like to see if you can disprove that stigma

I hope everyone realizes & appreciates the fact that if Rob Dahm didn't always have something breaking on him, this channel would not have half the of the great content that it does. Haha. Can someone please calculate the ratio of videos of Rob fixing something vs videos of Rob driving something. Lol.

Gave you a like specifically for showing the shortened spring and the visual on root-cause of the failure, damaged intake port and rotor pieces. Thanks for that detail!!!

Also, have you ever tried diesel fuel to clean parts like when you scrub those rotors? Used to use diesel on tractor parts and loved it 🤷‍♂️

Rob, just drop your doritos in a bath of atf+4 for a couple of days. They will be super clean after, all the rust, dirt, etc gone and your parts just slide apart. Then simple green to clean afterwards.

Hey Rob, the gallon of yellowish-green degreaser from harbor freight works very very well (much better than simple green, been there done that) for cleaning this kind of dirt and grime off Rotors like this. its a good idea to dilute it if you're soaking them, but spraying on the un-diluted degreaser works and its powerful stuff, also keep in mind that if aluminum is left in it for an extended period of time it can begin to dissolve the aluminum ( I used the degreaser solution to clean my front-cover, but didnt leave it in there, rinsing it after i was finished cleaning) Pure degreaser did cause some corrosion on a piece of aluminum i had (i did this as a test) after about a week or two.

those rotors look pretty trashed. they are dented, one might have seal groove clearance problems and they are possibly mismatched. if you want to run those i would check the clearance on that side seal grove and weigh them. i don't remember the spec off the top of my head but there is a spec for rotor weight cross tolerance and those "A,B,C,D,E" stamps on the rotor signify weight. gl on the build and buy new seals, 1000hp is no joke even on a 20b.

Aroumd 14:00....yo Rob, congrats on the 4 rotor! Everybody LOVES a happy ending!! I digress...industry standard (machining annahoo) for sanding presumably flat surfaces is typically a sheet of ________ on a known flat surface, put whatever you're sanding on said Emory cloth (

The letter stamping is weight marks. You never want to be more than on letter away (A,B) (B,C) (C,D). NEVER (A,D) (B,D) ect. I wouldnt use the dented rotor. But it will work.

Hey, uh the letter on the gearside of the rotor is the balance weight, to the right, clockwise of the bearing locking tab, mazda allows a letter either side, so a C balance weight, you can use a B or D balance weight rotor, personally I'd get the engine professionally balanced. Laterz

Rob, soak the rotors in a mix of pinesol and water 50/50 mix, let them sit a few days it will remove the rust, the burnt on fuel mix and everything, they will come out looking like brand new clean metal
