Post by: AndrewMack on January 05, 2007, 07:38:47 pm
how do you blow up a diesel motor without someone finding out. Like sugar in the gas tank type deal?

well yes but is there a way to blow up the motor without it being obvious. i mean.... the method of doing so. will sugar in the tank or draining the oil etc... something where no1 will notice.. if i can blow up this car then my wife will have no reason for me buying a new car.

disconnect the 12v to the injection pump. Then you can sell it and you won't be wasting a lovely diesel. BTW I'll buy it

aah so many ways i can think of to cause carnage
try soaking the air filter with a  whole can of ether before startup
make a hose to run into the cabin  from the airbox and inject the either  while running it
add a bunch of sand to the oil
that doesnt always work though,lol

my friend used to have a kawasaki 3 wheeler 160cc that we tried to blow up
we added a 16 oz bottle of gravel from the roadside,and it ran for another 2 years

im tired otherwise id have more ideas to ruin a perfectly good diesel
remove max fuel screw  and let it run away

maybe drain the oil out first too :cry:

fill up with gas by mistake one day without noticing.

'let' the water seperator get filled with water.

loosen the timing belt tensioner a bit so the belts  floppy, then take her for a high rpm boot down the highway.  When she hears that banging and crunching from under the hood there will be no doubt in her mind.

Dump a can of valve grinding paste into the oil.

But, did you try flowers yet?




I've seen lots of gassers run for a long time without oil.  A diesel might not fair so well with the tight pistons.

one thing is for sure... when it breaks you can't just say something like "oh gee... looks like we need to buy a new car!"  :lol:

she will obviously suspect foul play... most women are good at that  :wink:

Take a box cutter and put a few random nicks in the TB :) or the a/c belt since that drives the water pump right?
Title: stop it
Post by: FineFrank on January 06, 2007, 12:43:18 pm
Brer Rabbit molasis, about a quart, in the crankcase. It takes about two hours of running, it'll stop it. Two gallons of water in the fuel will stop the motor with no damage to the engine, but it will bollock up the fuel system.
Title: why
Post by: Darkness_is_spreading on January 06, 2007, 02:57:59 pm
Why do you want to do this in the first place,  if you car is good and runs nicely,  just take her out and show her the power of soot......   Maybe she has a Dark side in her.....  


If you want to sell it I come buy and grab it off of you,  we just  remove the fuel stop solenoid 12 V and crank for a bit,  bring out your Wife, and say well shes got low compression,  no fire,  motor is shot.   I got a truck that I can haul it away with.....  

Or  a you could thorw you IP off time by a tooth, and try to start it,   It might not start  but it might start and Run like ass,  smoke and everything......   On no  My motor is a blown up....  

But seriously why do you want to grenade this diesel,   just sell it if you can,  but grenading it seems like a waste.

Post by: RabbitJockey on January 06, 2007, 03:00:17 pm
yeah disconnect the fuel solenoid and sell it, don't ruin it for nothing.  diesel run aways are pretty amazing to watch, i dunno how you could cause it to happen though, possibly pour alot of oil into the intake

nah, ur not a good vw mechanic unless you've blown one up.  it's amazing, as much as it sucked, i loved watching my rabbit blow up, it was exhilarating heart pounding and a huge adrenaline rush, in a car buff type of way.  amazing.  it was a show for your ears nose eyes.  just insane.  i think i blew my jetta too but i'm not sure yet, but both times i knew what i was doing.

"How To Blow Up A Diesel?"

    Not really that difficult.

    A Golf is probably easier than a Jetta.

    When I blew up my Golf, I used Helium,
 
    but I forgot to tie a string to it.
   
    The last time I saw it, it was at about

    three-thousand feet and heading in the

   general direction of France.

there was a guy who ran slick 50 in his airplane then drained the oil... then flew it (he must have had huge balls) but his plane didn't die in the air... good thing you werent running slick 50 huh???  :roll:

can we please revise the intentions of destroying your engine?  i think we will need to call on the diesel judges... you may be charged with first degree diesel murder.  cold... calculated destruction of your motor!!!

you said on your post

Sounds more like you need to change wives than get rid of/ destroy the car. Just my $.02

if it was an na you could have some real fun like take out the air cleaner stick bolts in the air cleaner housing (or nuts) and and put it all back together go for a drive with her and when you accelerate the nuts and bolts will roll down the runners and into the vavles causing them to stick and make lots of noise. Or there is my favourite..... Drain your windsheild wiper bottle,cut your hoses and direct them into the intake, Spray as much either as you can (2 bottles if you can) and quickly tape over the lid and seal it off. Take her out for a ride and simply  "WASH" your windsheild and throw a piss load of either into the engine at a mid to high engine speed. :D

hope that helps...

Post by: Darkness_is_spreading on January 08, 2007, 10:55:26 pm
I was thinking the same destruction,   maybe 91 octane,  run about half a tank and wait for a boom, the high compression ration of the diesel will just love the gas and diesel,  I have only heard the this is like putting a gun to your head for a Diesel so  DO it and tell us what happens.....


If you would like to donate your car to me,  well I could make it look like it crapped out,  smoking like a chimney, and  to top it off I'll bring a quart of oil motor oil and pour it on the ground and say hey,   I think shes got a leak EH!!

Post by: rabbid79 on January 09, 2007, 10:12:51 pm
You'd be suprised how long these little diesel engines will run w/o oil.  I tried that very thing once. (I was upgrading the engine to TD, so I didn't need the N/A, and nobody wanted it anyway.)

We drained the oil and ran it around in a parking lot for about 10 minutes.  It gradually got lower and lower on power, until it finally quit.  We thought we were done, but once it cooled down, it started right back up.  It seems the pistons were swelling with the heat and eventually getting too tight in the cylinders.  We did this over and over, but couldn't get it to die for real.  Eventually we tossed sand into the intake.  Didn't help.  Then we tossed in some gravel.  That worked.

After the TD swap, I pulled the head off the N/A, and there was a bunch of rock powder that was keeping the pistons from going to TDC.  That's what eventually killed it.

By the way, yes, there was some very serious scoring on the cylinder walls.  I don't know how much of it was from the lack of oil/excessive heat, and how much was from the rocks.

Thats friggin awesome,  If I could get another NA motor for cheap I would do the same,   run it without oil,  and see what it could do.....  

This is similar to and Aircoole motor priciple; aircooled motors use circulating air to cool the piston walls and, the motor oil cools the internal bits.  

How could the motor keep up with the excess friction of the piston rings and pistons rubbing on the dry walls of the cylinder. It would slowly build up, but since there is no oil,  really you are just breaking down the rings and pistons and the bores of the cylinders with the lack of Oil.  

As to how this coul start up after cooling down I have no idea....

Post by: SMOKEYDUB on January 10, 2007, 07:34:08 pm
i would go for taking off the oil pan and loosening the rod bolts then finger tighten them and magically take it out for a drive and KABOOM!

Post by: burn_your_money on January 10, 2007, 07:46:21 pm
Disconnect the fuel filter and put the feed line in a gas can. Loosen all of the injectors. Crank until there is no diesel left in the system. Let it sit overnight so the gas in the cylinders evaporates. Then soak the air filter in chlorine. Hook the injectors back up. Using a remote starter give'er.
For a remote start all you need to do is run a long, long wire connected to the positive on the starter and the solenoid on the starter. Touch the two together and if everything goes properly you should get some flying metal parts

It would be good to know how many RPMs these things can go before they pop.
 Can't find your limits until you exceed them ya know.

I agree that it is a total waste, but it's not my engine and if he has it set in his mind to blow it up, he may as well do a good job of it :twisted:

I'd love to buy the engine off of him, I need a few NAs
Title: how to blow up a diesel?
Post by: jtanguay on January 11, 2007, 08:11:12 am
i was actually considering the feasibility in making a generator out of either a turbo or an N/A... probably better to sacrifice an n/a :)

the exhaust heat and engine heat could be used to heat the house, and the generator could be used to store electricity in batteries, and run household power.  would be a great backup source in case of emergencies.  these motors can put out a LOT of heat!!!

grind 2 exhaust lobes off, gut 2 injectors, connect those two injectors to an air tank, add a pressure release and viola, air compressor.  

Blowing motors is a long time VW thing.  Back when GTGs used to be called 'bug ins', you could pretty much count on someone bringing along an old aircooled motor to run to destruction.  If you really want to blow it, in the interest of science: put a EGT on it and slowly increase fuel until you find the critical temp.
Title: blow it up
Post by: fatmobile on January 12, 2007, 12:45:13 am
Critical temp for an NA might not apply to a TD engine.
 I say hook a tach up to it and let us know what the maximum RPM is.

i'm liking that idea... a diesel powered compressor!!!  

and as for blowing the engine... i agree that it 'should' be done scientifically.. find the breaking point of the motor and share results :)

hehe hook up an rpm sensor, and make the governor a solid piece... wonder how many rpm's these motors can take  :twisted:

Post by: LeeG on January 13, 2007, 03:27:46 am
Your right.  A simpler version of your better idea would be to grind off intake AND exhaust lobes and replace both valve springs with very light springs so that both valves are sucked open on down strokes.  You'd also need a custom 2 cylinder exhaust manifold.

I have a old fairbanks morse 4 stroke engine that only has one cam lobe which is used to open exhaust....intake is sucked open as above.

ive done this to plenty of old junkers that wouldnt sell for $50 locally. normally i would never blow an engine that had any value.

diesels are some tough things to kill. i had one which was hit in the front end, the car was junk, the engine was ticking badly, radiator leaked all the water out. the engine wouldnt die even after installing a fuel line to the intake and running it to the passenger area where my assistant sat with 3 cans of ether. that exhaust smoked ORANGE but the engine wouldnt blow after 3 cans. i had never seen an orange coloured diesel exhaust before, and that engine had some wicked power running on ether. it ran like it had a turbo. we finally killed it by just running around town at full throttle in 1st and 2nd gear. the engine finally locked up, but i popped the clutch and unfroze it and got home anyways. decided to call it quits after the fire truck came because the thing was smoking so bad out the exhaust and off the overheating block/head. you know its bad when the fire truck pulls you over to tell you youre car is on fire. (although it wasnt). i just told them it was a diesel, they do that.

on one engine i wired it to full throttle cut off the upper rad hose and walked away. 15 minutes later it quit running. my infrared tempature gun got a 600 degree reading off the fuel injector. after it cooled off that engine fired up a few more times and ran for 15 minutes at a time untill it got hot and stopped. never did kill the engine but it made some awfull racket the last time i ran it.  it sounded like sledgehammers beating away in the block. 600 degrees cant be good for th thing, but it never actually blew up. it would just get hot and quit running.

I ran a faulty fuel injector in my new head....
about 30 minutes later, the fuel spray burned into the water jacket with a loud POP! :roll:
