: Engine eats rubber gasket and LIVES!!!

So this is pretty stupid, but I had to laugh afterward anyway. I'm doing some work under the hood, and I have the air cleaner hose disconnected. I didn't pull the rubber gasket off of the adapter, it's just sitting there (that's the stupid part :shaking: ). I take a quick drive around the block for a test drive and sure enough, as I hit the gas that rubber gasket manages to get sucked into the carb. It lodged in one of the butterfly valves, giving me a quick dose of panic wondering why the throttle was stuck. Then it freed itself and managed to keep the intake valve from closing all the way (as evidenced by about 20 rapid backfires through the intake manifold). Then it completes its path through the engine and lodges itself in the cat. I've shut the motor down by now, and can clearly hear popping and crackling coming from the cat, along with a distinct smell of burning rubber.
Motor still works fine :D

I wuz assembling the top-end for my Ducati 250 racer back in the 60's. Very careful. Take my time, everything just so. But afterwards it didn't feel right, or sound right when I kicked it over. Finally took the head off again. The clean rag I had stuffed into the bore wuz still there! Not so clean anymore but Hey!

Also in the 60's I drove a Renault Dauphine (Ree-noe Doe-feen). Also a Peugeot (pwew-zgoe with a soft 'g'). Anyway, I pulled into a service station, the kind they had back then with an actual Hwew-man Bean. The radiator filler was next to the engine in back. I opened the rear hood, got the water hose out to fill the radiator but in a spaced-out daze I filled the carb instead. They were next to each other and I had the air filter off as I wuz workin' on it.

This guy came out, "Can I hep you.... WHAT the F****!!! That's the carb! Waaaait! Am I on candid camera? He is seriously looking around! I have nothing constructive to say so I jump in, crank for a moment then zip away. Sometimes the best alternative is to just duck your head and leave I think.

That reminds me of the time the cat decided to sleep on the warm engine on a cold night, and mom had to make a quick run to the store for milk,,,, THAT WAS A MESS,,,

when i worked in a lumber yard, the supply drivers would tell us all kinds of wonderful cat vs deisle fans stories.... and how they would go back inside and wake their kid up and make him go clean the cat off the under side of the hood.

i had a buddy that built a really nice 350 in auto shop his senior year. he was a cool enough guy but had plenty of enemies. well at some point a 9/16 socket made it into the piston chamber..........and BEAT THE FAWK out of the piston valves and head. he saved the piston, has a nice big chunk of the socket embeded into the surface.

I pulled into the gas station to fuel up. A flat-bed one-ton delivery truck pulls up and the driver begins to fuel up. I glance over and notice that there are 4 1/2 cat images painted on the fender. I almost choked laughing so hard. Then I asked the guy about the 1/2 cat. He said, "You have heard of an 'assist' haven't you"? And I busted up again.

My score hasn't been so great since my soft-hearted cat-loving daughter was born. But my neighborhood is still relatively cat-free. When I moved in I saw five (5) cats in my backyard at the same time! I like lil tweet birds. I had some cute ones feeding on the ground in my yard, lil White-breasted nuthatches, a Hermit Thrush, Red Shafted Flickers, Towhees and lots more. So, I decided that when I am in a position to determine who lives and who dies, a native species whose population is declining, or a cat, I will choose for the native species everytime. I have a Sheriden Blue Streak. 5mm ten-pump pellet gun. With a nice scope and a tight pattern. Sighted in for about 40 yards (200 feet across my back yard). It won't stop a cat like a 12 gauge slug-gun, or a .223 hollow-point, but they do die. It will put a pellet straight through them. The short way, haven't tried it the long way.

Way I see it, the birds are protected species. If I were to kill one I could go to jail. Recent court rulings show that if I kill a cat I will go to jail. But the cat, introduced into a local food-chain as an exotic [1], can kill whatever it wants with impunity. And the cats that got into my house and tore up $4000 worth of brand new sheers (I learned this new word, it means curtains behind the drapes) can't be prosecuted (under the law :-) neither can their owner. But true justice will prevail. And has prevailed, multiple times, and I suspect it will prevail again. :smokin:

[1] and I don't forget that the cats spray my tool box, my drop light, my walls.. they poop in my flowerbed by my door till it smells too bad to use the door, they yowl at night when i am trying to sleep, the spray in my Zuke when they can get in, the climb all over the nice car's paint, they get rabies at 3X the rate of dogs, yet do not have to be leashed, licensed or innoculated. Plus they just don't have no respect. :mad3:

Happened to my buddy too in high school. We rebuilt his 360 and we had put paper towel in the intake to keep dirt out. Someone stuffed that deeper into the manifold then topped it off again. When he put it into his car and ran it the paper towl ended up through the engine and fawked all the bearings etc. He had to tear it apart and rebuild it again. :mad3:

Don't put sugar in the oil of your Suzuki!

Many years ago I was looking over a reposessed car, a nice-ish Celica, at the credit union. The engine was locked up and nobody bid on it. I got it for $100. Took it home, pulled the engine, started tearing it down. Everything looked just fine except that the oil looked funny. It was powdery black, and really thick, not as hard as peanut brittle, but harder than fudge. You slice it and it has a whitish look to it. It was sugar! Papers in the glove box indicated a recent tumultuous divorce. I believe she got the car without displaying much integrity.

The only part that needed replacing was the cam chain tensioner and I am somewhat convinced that all 18RC's come from the factory with this needing replaced. I had taken everything apart except one main bearing. I took all of the rods and pistons out, disconnected everything else from the crank, but that one bearing. I put my big socket back on the crank pulley bolt, with a long cheater, and *still* couldn't budge that crank. Hard to believe that sugar is so strong! Apparently it melted and the sugar syrup circulated with the oil until she shut it down. Then, like sugar syrup is wont to do, it turned back into a solid.

The car ran great after I assembled it. Nice mileage, quiet, and it really loved to run on the freeway! I made some money on it.

Ever try gas in a diesel. So, I hear, it will rev the engine out of control till it blows.

My buddy and I were in Moab a few years back, in his old CJ-5, which trail cant remember. We heard a very odd noise, then the engine just shook. But was running fine. We popped the hood. And it was just vibrating like hell. Then we noticed light was shinning though a slice in the hood. A fan blade had come off and shot right though it. We think its still in orbit.

That seems a little extreme, I can't understand why... even if the pump failed I can't see a failure mode that would allow more fuel like that.

My 1990 NA Ford diesel 7.3L owner manual says I can run up to 30% gasoline. I would guess maybe it would help it start in the winter. I use a fuel lubricant already to help my pump last longer, since they took a lot of the lubricity out of the diesel when they took the sulfur out. I'd hafta use a lot more if I ran 30% gas in there I'd think.

out of control till it blows.

I think one of the limiting factors of rpm in a diesel is the ability of the pump to pump that fast. It just don't make sense unless somehow it jams the pump so it won't respond to the throttle. Diesel contains as much or more energy per 'squirt' as gasoline. Keep in mind a diesel BURNS fuel, it doesn't explode it. Once the gasoline is successfully pumped into the cylinder when the air there is hot enough to ignite it, it just burns like it does in a gasoline engine. Foof. The diesel machanical parts are heavier than a gas engine, I am sure they can take the strain. I can't visualize how gasoline would make it run faster. Hasta have been some incident with a jamed pump I'd think.

I usta drive an old crawler that had two fuel tanks, kerosene and gasoline. You start it on the expensive gasoline if ya hafta, then switch to kerosene. This wasn't a CI engine, used a sparkplug.

. No it doesn't. We get them in all the time at work. usually when the wife takes the truck that' one time' and decides to fuel up. the attendants never seem to notice it needs diesel, not gas. Not nice to the injector pump, but never blows the engines. they always come in on the hook, because they won't even start.

maybe not as a partial mixture but I would think that its possible if you got a diesel runing and switched it to mostly gas you could get that reaction, especially on an older engine. anyone ever used the trick of putting a rag soaked in gas over a diesel intake to prime the pump? I'm not saying it would for sure but I wouldnt totally discount it though.

During World War II, when gasoline was scarce and rationed and kerosene was easier to get, one of my in-laws rigged a Model-A Ford so he could start it on gas then switch to kerosene. He drove it that way from California to Mississippi and back. You adjusted both spark and mixture on the Model A from the driver's seat as you drove so it ran fine on either one. The kerosene apparently burned the valves so he had to do a valve job at the end of the trip, but that wasn't much of a job on a Model A.

I was doing an oil pump on my 71 Nova with an LT1. Somehow I left the tube of yellow gasket adhesive INSIDE the pan when I put it together. I never even knew it!! About a year later I wrecked the car and dropped the pan to do a lower end inspection before I put the motor in another Nova (my 66 wagon...which was Nova #16 for me btw). I nearly died laffing when I found it there. I took the cap off the tube and believe it or not the adhesive was still good.

Ask Eddie or Tom from Spidertrax what happens to a diesel when ya put gas in it. When they where makin the trip to Moab from Jersey with a rental truck (2 zuks in side and one flat towed) somebody put gas n the tank instead of fuel and they had to drive there zuks from the other side of Colorado to Moab.

it is possible to get a 15 liter diesel engine to rev up well past the pumps ability to govern the engine (2g's) this is called a run away. it can happen when the fly weights inside the mechanical governor self destruct and looses all ability to restrict the fuel rack's movement, causing the diesel to keep on accerlerating. the other way to get a run away is if the turbo blows the seal, and starts pumping oil into the intake, diesels can run on straight oil, should this happen, you can't shut it down, cuz the fuel may be stopped, but the oil will keep it running.

we have seen where a 15 liter diesel has hit over 6500 rpm before finally tossing a rod through the side of the block. also, it happened to one driver *governor failure* while driving, all he said was, it had REAL good power climbing that hill... till i realised i couldn't slow down... then there was a BANG.. and some unpleasantness... one hell of a ride though!
