HPI K 5.9 nitro engine Destruction!

[@maxxman1234]

Every time I traded an rc or bought one there was always something fucked up the seller didn’t tell me about like stripped screws or gears. Literally every time.

[@thebug4046]

Oh I know! The truth factor is zero! Lol

[@jbabister]

every single time without fail when guys use the silcone....they BLOW UP...its so funnny... keep buyin those engines... i have had the same k 4.6 for 18 years now and never blew up once.... runs like new

[@thebug4046]

Some silicone can actually be abrasive and corrosive so it can do damage. But yeah lots of 5.9s blow up i see it often and the parts are ridiculously expensive. The K4.6 is a great engine 💯

[@jbabister]

​@@thebug4046 never sealed one or used any kinda silcone ever....just open the engines spray them out with break cleaner, add break in oil and run it... No break in tanks... just a couple heat cycles at idle.... never blew up once in 30 years

[@jbabister]

@@thebug4046 my traxxas nitro ruslter engine should be in the rc hall of fame that lil engine 2.5 has 15 gallons of fuel run through it and still today fire up and blast by guys with new engines

[@thebug4046]

@@jbabister i usually run 4 heat cycles before I start driving and break in oil? I'm assuming you are taking about castor oil? I usually add extra blendzall castor oil for the first quart of fuel

[@Matthew_Does_To_Many_Things]

That looks like a neat engine. Must have been a wheelie monster. After some quick research they don’t really have parts for sale in the U.S

[@thebug4046]

Parts are hard to get and very expensive. The K5.9 is okay not as good as every one thinks and very fuel hungry

[@tylerbarajas8704]

The engine has a assy smell lol that's great

[@thebug4046]

It literally smells like someone farted on your head. 😂

[@ChrisFay1996]

The new Savage xl should be arriving sometime this week, excited to play with a .36 nitro

[@thebug4046]

Make sure to have lots! Of fuel on hand the 5.9 has a drinking problem 🤣

[@cassianomartin2699]

Got a used savage XL, it came with the k5.9, new sleeve, piston and connecting rod. Lots of pinch, engine is really in a good shape, except for the old owner left the engine with fuel inside for more than a year... it fooked up internal bearing, got a new bearing for 10 bucks from china

[@thebug4046]

Nice a good cleaning a set of bearings should be ready to go!

Hi buddy just watched your video it's alsome bro great info 👍👌

Not really when you get 3 trucks for 150$ including a gallon of fuel lol we got lots of engines

[@josephsaucedo8691]

I can get the frame side plates for 6$ for the set and depending on what else needed for not more than 20$ for the front or back end 👍👌✌️💯🏎️🍻⚒️

[@thebug4046]

Nice!

[@tonydetwiler2624]

I have 3 of them engines 2 pretty much new sadly one has that red seal stuff tho and the third one has a shot backplate so it’s kinda beating the bottom end apart crank and rod may still be ok tho not sure it still seems mostly tight no slop

[@thebug4046]

That's what wrong with this one to!

[@jimmygeorge4268]

You are my go to for everything nitro,,,,,,but out of curiosity I look at others putting the front bearing in with both seals installed…how does that keep the bearing from being lubed. A few channels I watch all keep the front bearing with both seals intact,,,to me it seems to be wrong,,,,or does it make a difference…just curious…. Keep ‘em comin”

[@thebug4046]

It's been an ongoing argument for many years I have tried with and without and the front bearing doesn't last as long with both seals in as it will received no libercation it's pretty stupid there's letting no engine manufacture that I have ever come across that believes in both bearing seals as also they do not really seal the bearing as they're more or less a dirt shield. I have done testing on the subject for the last 20 years and seen no difference other than bearing life with one seal removed is increased. The bearing itself like I'd mentioned before does not seal the engine lack of tuning a rich low speed or over rich high speed will actually create fuel build-up in the bottom of the engine which will push the fuel past a front bearing and make a leak no matter what you do

[@jimmygeorge4268]

@@thebug4046 Thanks,,,that was my very thought,,,I don’t know why some individuals leave both seals on…..they may not the second time around…DAH….

Hey Man. Got an old Ofna force 3.5 .26 engine. Do you know what piston sleeve go on it. Looking around and I see a .21 and a .25. I’m like. “wth where is the .26?”. Is .25 a special one? And the .21 go up to .26?, Ima keep looking. But I did see different p/n numbers .21 52040 & .25 52042

[@thebug4046]

Hey bud sorry I'm not 100% but if you post in Nitro RC enthusiasts group on Facebook I'm sure one of the guys can tell you exactly what you need.

[@huck462]

That 5.9 engine looks like someone tried to run pump gas in it or ran very Lean, the previous owner should stick with electric vehicles

[@thebug4046]

Yeah the original owner was a bit of a tool to say the least.. lol

[@hpiedsavageed7608]

You can get the f5.9. But it's expensive. Force sells one for cheaper

[@thebug4046]

600$ for just the engine in Canadian eBay 🤣🤣

[@speedgears1236]

K5.9 parts are so expensive because they are hard to get. I have two k5.9 that need piston and sleeve. What I was wondering where are the pieces. Someone obviously took it apart prior to you. Shitty sellers.

[@khaosnitro]

forget it! toss them out i bought a new F5.9 didnt last 1 quart of fuel

[@thebug4046]

Oh man unbelievably expensive not worth the time or money

[@cassianomartin2699]

dude, it ripped off piston bottom! how did that happen? Running too lean?

[@thebug4046]

Over reving and running to lean

[@amputeerc9298]

I wouldn't sweat it, damn things drink way too much fuel anyways. And it seems like mine really prefers 30%, which makes it even more expensive to run. I'm sure a big red or just plain ol sh .28 would rip an xl just fine.

[@thebug4046]

Last time I ran a 5.9 it would eat a tank in like 5 minutes lol can't even get the parts for it here. I found a piston and sleeve they were asking like 250$ 😆

@@khaosnitro They are a tight pinched engine so preheating and keeping the cylinder had wrapped to help keep the sleeve expanded away from the piston during the break and cycle around 230ﾟF really helps prevent issues like that a longer break in is better with additional klotz castor oil added to the fuel to increase film strength

I believe axial makes the k4.6 and k5.9 parts are still not cheap for them Id throw an lrp .32 spec4 on it or for a bit cheaper get a force.32 or sh.28.. I just recently got a savage x roller had a blown up k4.6 looked just like the engine in your video as far as damage and I’ll be ordering that lrp .32 for it here in the next month or so.. btw what’s your Facebook would be cool to share our rc rebuilds with each other.. currently working on an ofna titan a hyper 7 pbs the hpi savage x an hellfire and a Rc10gt also have a lot of parts/engines to a lot of other nitro rc’s let me know your Facebook or shoot me a reply on here if you ever want to talk rc stuff

[@thebug4046]

Honestly I've had a few of the LRP32s apart and I wouldn't buy one the the sleeves are really poorly made lots of casting flash and shotty work. The carburetors suck and don't hold a tune very well either. They used to be way better about 7 or 8 years ago before the new owners took over and did shit work. I have seen better quality in a 80$ China engine. They might be better now but I wouldn't pay what they are asking here at 500$ the big red is cheaper and runs better
