Metal shavings in engine

You'd have to add so much shavings that it blocked the pickup or oil filter before it really was a problem.

Right. But sugar will? Trust me, if you have large shavings in there, they'll find a way to get around.

But sand or whatever in teh gastank wont do much more than kill the fuel pump, and maybe ruin your injectors. Sugar in the gastank though = fucking mess. So. Make sure they don't do that.

sugar doesn't desolve in gas, it would be stopped by the pickup screen on the pump. The only way you could get the sugar to desolve is to add water with the sugar

the metal wouldn't circulate, but it might score a couple things on the way to the oil pan. Such as cam lobes. Thats about it in most engines.

If metal could easily get past the oil filter, motors wouldn't make it 1000 miles before taking out the plain bearings. You'd be surprised how much crap is in any engine.

Myth busters proved that wrong, its common myth - I agree with bob, it wont do anything but sit in the tank.

oldest myth, I agree

i think the only problem it causes it that if you put enough in it can block the fuel piping/pump/filter.

otherwise very little.

don't many cars have a screen/filter before the scavenger/in-tank pump?

Im not saying that the oil filter wont do its job, what im saying, is that with THAT much shavings, tehy WILL get into things. The oil in the pan is being splashed about as well too. The IS300 had #5 and #6 rod and crank bearings wiped out from the sugar in the pan. One of the bearings even had a hole worn through it. Im sure if sugar can make its way around and cause that much damage then then metal shavings would do a number on the motor as well.

ITs eaither that, or the sugar (and shavings) plugs up the oil filter and you have a loss of pressure. But the oil light wasnt on in the car. Either way, haveing that crap going thorugh your oilpump will destroy it too.

its really a question of the amount.

I couldn't agree more. 1 tblspn vs a whole 5# bag.

As far as the OP goes You are probably worried about something that will never happen to you. Good luck anyways with your car and "freind"

There was about half a pound of sugar in that motor.

That would make a mess, easily enough to clog the filter, open the bypass, and fill the oil passages with sugar syrup. mmm tasty. Did the enigne smell like burnt caramel when it was taken apart?

What if this guy put dirt or sand in the engine through the Oil fill? I have even heard he may crawl under, remove the oil filter, empty it and fill it with dirt/sand/metal shavings etc.. What would these types of materials do to my engine? Could your mechanic tell if dirt/sand/metal shavings had been put in the engine? I am not a car expert but it would be nice to know what to look for so I could catch it early and also nab the guy if he really pulls it off

Ok get a locking gas cap. Problem solved for pouring stuff in your gas tank. You hood shouldn't come open unless they have access to the hood release INSIDE the car. Keep the car locked and you elimited the problem. Also if he takes out the oil plug aren't you goign to notice a big puddle of oil underneath your car? As for the oil filter putting the stuff in the filter will only keep most of the stuff in there considering it's a FILTER.

Trust me don't beat the heck out of him. A guy knelt on the hood of my car and put over $500 in dents with that kneeling and was generally an asshole. I punched him one time. I ened up giving him a concussion and he went into a seizure. They called an ambulance and he spend a night in the hospital and went through a ton of test. Needless to say if I wasn't charged as a juvinile (I was 16 at the time) I'd have been facing a feloyn charge of substsantial battery and the medical bills (which I did have to pay) were big.

I know that a coffee cup of brake drum chips dumped down the oil fill will eat up a motor in about 2 weeks time. And it is virtually undetectable after the damage is done, sort of gets lost with the torn up bearing material.

Just to let you know the oil fill is UNDER THE HOOD. If you don't give them access to the inside of the car they won't be able to pop the hood in the first place. Unless they pry the hood open (which is really noticeable) you shouldn't have a problem.

actaully no, the sugar didnt melt, it stayed granular.
