Most Devious ways to grenade an engine.
liam.mccaffrey - 19/1/10 at 05:57 PM

We discuss this in work all the time.

My favourite is a ball bearing down each cylinder. Though not particularly quick to do.

I think in the states the authorities run the engines f confiscated car with some sort of resin until they stop

What about replacing the oil with some kind of liquid which sets when it reaches the right temperature?

tomgregory2000 - 19/1/10 at 06:00 PM

A grenade in the engine bay and a piece of string attached to the pin and the other end attached to a solid object.

Drive off and BOOM

liam.mccaffrey - 19/1/10 at 06:01 PM

Yes! Literal as well

Start the engine then pour water in the fuel tank

BenB - 19/1/10 at 06:05 PM

By grenade do you mean knacker?

Aliminium oxide grinding powder down the dip tube?

Otherwise a piano TG vs. Marina stylee does the job.

bi22le - 19/1/10 at 06:08 PM

pull of a water hose. Nobody would notice that in a normal car. Untill the warning light comes on that is!

what's that going to do? Unless you leave it for a long time and your engine goes all rusty? Water injection is used on boosted engines (okay, it's not stuck in the blooming tank but the principles the same)...

Yup- my mate found someone had slashed the lower radiator hose on his work van (presumably to follow him and do him over a little up the road- he's a jeweller). Nasty- the light won't come on because that's normally bathed in the coolant. No coolant- no heat transmission, first thing you know is the engine seizing....

Cash for Clunkers - destroying engines the Govt. mandated way!

Liam - 19/1/10 at 06:32 PM

What are you looking for exactly? Rapid violent destruction, slow but stealthy, or artistic impression? I'd say chucking a load of sand/gravel in the intake might be good for the first, some sort of coolant system sabotage (slash a hose) or fuel/oil contamination for the second, and I'll need more time to think of something interesting for the third

Brake fluid down the inlet!

That is one insane piece of legislation.

And I thought scrappage was nuts.

Actually writing into the legislation that they have to wreck the engine is just bizarre.

BenB - 19/1/10 at 06:43 PM

Give it to a woman and send her to a filling station that has petrol and diesel

(said the very scared man running for cover)

It is all that is wrong and evil compared to LCB website

MakeEverything - 19/1/10 at 06:57 PM

replace the oil with watered down grinding paste and rev it to the max ubtil pop.

Feed the inlet with propane, and replace the fuel with alcohol.

The big car companies wrote the legislation (via their bought congressmen and lobby groups). Makes a lot of sense for them.

If you do this when the engine is running its great for de cokeing(sp) the bore

scudderfish - 19/1/10 at 07:25 PM

How about a load of polystyrene beads down the inlet? Most would burn, but it'd make a very sticky mess inside.

sebastiaan - 19/1/10 at 07:33 PM

I'd say it is a good thing getting rid of those (mostly american V8 gas guzzling....) monstrosities.

Even if you belong to those who oppose the theory that we as humans are causing global warming, you must agree that we are using up oil at an alarming rate and that the oil that is still there is in increasingly unfriendly places.

Middle-East, anyone?...

Ninehigh - 19/1/10 at 07:36 PM

Trying to remember what Mythbusters did... I think it was bleach in the oil, still ran though (like a sack of s**t)

If you want something quick swap the petrol/diesel and for artistic make the throttle cable a little sticky

Am i allowed to say that??

Yes but only if there is a "pikey" inside or lots

davie h - 19/1/10 at 07:59 PM

when i was a mechanic i saw a guy who had cleaned the air filter on a escort diesel van with brake cleaner solvent stuff he then stuck it back in the van and started the engine it went off like a bomb reving like mad he took the keys out and just stood there as the engine kept on reving higher and higher until it threw a rod,i could hardly stand up for laughing.

i have also seen plenty of recked diesel engines that have blew up due to running on their own engine oil.

And only if the caravan is covered in napalm along with the neighbouring ones

Remove the sump plug. Cut the oil presure switch wire if you don't want it to show.

Arent forums great for putting together a "proper" plan!! Great attention to detail there chaps!!

One of the comments on that youtube page says it all.

"why don't we all boost the building trade by burning our houses down ?"

Says it all.....

Whilst travelling on the motorway change from 5th to 1st and release the clutch...

Whilst travelling home from london I saw the car in front of me do this on the M3... Got out to lend a hand, opened the bonnet and once the smoke had cleared saw the conrod poking out the block.

blakep82 - 19/1/10 at 10:35 PM

a handful of thermite in the air box (between filter and engine obviously)
would that suck in enough to work?

[Edited on 19/1/10 by blakep82]

Ninehigh - 19/1/10 at 11:54 PM

Think that just make it go like f**k, however if you put it in some tin foil and stuck it to the top of the block when it ignites it'll melt through

liam.mccaffrey - 20/1/10 at 12:03 AM

My grandfather used to run pollution boats and he told me about the time the "boys on the refinery jetty" gave him a bucket of Naptha to clean the floor of the engine room after an oil leak. His deckhand duly did so without shutting the diesel boat motor down. Engine revved itself to bits.

irvined - 20/1/10 at 12:46 AM

For stealth, just undo the sump plug a couple of turns, that way after they check the oil and set off, and eventually the oil pours out and the engine goes a bit funny, you could also remove half the cam belt.

For quick, some sand in the oil?

morcus - 20/1/10 at 01:47 AM

Rewire the dash so that the wrong warnig lights come on, then do some thing nasty and watch them try and fix something that isn't broken.

Ninehigh - 20/1/10 at 01:49 AM

While you're at it you could rewire the gauges so the engine fries while they think it's still warming up and they get clocked for doing 60 when the speedo says 25

morcus - 20/1/10 at 02:35 AM

Wouldn't you just love to re calibrate someones speedo?

Swap the Speedo and the Revcounter round, that could cause some confusion.

"Aargh! I'm doing 110 in 1st! And at about 75rpm? Wait a minute..."

liam.mccaffrey - 20/1/10 at 08:07 AM

Some great stuff there, definitely style points and some good stealth suggestions too

Daddylonglegs - 20/1/10 at 08:31 AM

Or you could just give the keys to ex-F1 driver Johnny Herbert, he was really good at breaking cars

Vindi_andy - 20/1/10 at 04:56 PM

Sugar in the fuel take.

Turns to toffee in engine

When the middlesex RS owners club used to have the annual big meet local to me, they would trailer in an old ford (last one i saw Mk 1 escort 1300) remove oil/water start run at full chat and take £1 a ticket for times of complete failiure.

I had 1 minute 37 seconds for the escort, i was gutted when the official time was 1 min 35 secs
