Default How many engines have you killed and why?

Anyone out the got any interesting stories of killing there rc engines.

My mates first engine was a Novarossi bonito.

He brought it because he said it was the best engine. (info via google)

No Nitro knowledge

He blew it up first tank.

hmmm....in my many years of nitro running and improper care:
Go 5 port Silver Head(rear bearing seized and snapped crank in half)
OS V spec (Dirt in the motor after air filter wasn't secured)
Friends Old Nova Plus 4( broke crank in it to lmao)...not really sure how
Nova Frankenmotor(p5,w/on-road crank) never really blew just didn't work or tune properly
most of my motors got sold before I ever put much life through them though

I had a force .32 that blew up after like 5 tanks,

Got no idea what i did wrong but it seized.

this is no joke but my mate who had the novarossi bonito got a new sleeve and piston but couldn't tune it properly and the force.32 was faster in a way heavier car.

It was laughable.

O.S .15 in my GV BV1. Filter element popped out of the retainer and dusted the engine.

Force .25 in my 1st truggy. That engine just got flogged and flogged and flogged and flogged every race meet and just wore out.

LRP .12 my first "race" engine. Ran it for ages at club event and big race meets, and I was new to race engines and wasn't told you had to replace the rod after so many hours of running and ended up putting a rod through the block.... :/

I drive my engines hard and never really had any issues actually blowing a motor up, hope I didn't jinx myself. Typically engines break for a reason, lean tune is the number one reason because it leads to seized rear bearings or the copper inserts on the rod go or the rod will snap when oil burns up to fast. Now I've seen rods go through cases, cranks snap bearings seizing and I've actually seem a front bearing leak from being to rich but 99% of the time these things happen from one of the needles being to lean.

One thing I try to check every time I drive is the under part of my filter neck, onetime I couldn't get the engine to tune because there was a year in the carb neck that I couldn't see and it almost destroyed my engine. You always have to overlook everything from exhaust fuel tubing to the carb boot even check your high speed needle to make sure it's not lose because all those things cause big problems if they suck dirt.

the only motor I've ever killed myself was a nova mega. It came new with my serpent. but I guess I ran it too lean it broke a rod. bought a new rod, piston sleeve and it lasted a good year before I sold it with the car.

I havent broke and engine yet!
Oh I kinda have... In the buggy the center diff bearing got toasted and put to much pressure on the clutch bearing that also siezed up and started to rotate on the crank shaft.
The crank shaft is toast now and I can't get a hold of a new one, So I guess the engine is a gone'er.

Otherwise I DON'T think Nitro Engines are hard. Just understand the principle and youre fine!

I have an entire shelf devoted to expenatures ( blewed up motors). Where to start...
got 2 OS CV-Z .12's One so worn out it wont run but at 1/2 throttle or more. The other ran an entire 20 minutes so lean it warped the piston. Came off at 300+.
I got 3 Sirio's/ Trinity's. One the sleeve broke in half ( 10 gallons), one that broke the crank pin 6 gallons) and another worn out it has zero compression and the sleeve is gouged out (15 gallons).
I have a Picco 7 port that the front bearing came apart. the crank then wollered out the case and its toast (8 gallons).
Another Picco Base model 3 port (my boys when he was learning to drive nitro) that only runs good around 280* or more. (12 gallons) Still runs.
A Werks B6 that the slug came out and milled the rod 3/4 of the way thru!
I had 2 OS V-Specs that were worn out/ broken (got hit at the Over/under and cracked the case) but sold them for parts.

And a handful of electric motors too

There is a couple grand worth of paper weights up there!
