Automotive question(bent connecting rod?)

And also If you have bad rings on the pistson I believe they are called? Oil could make its way into the cylender and Oil doesnt also compress.

No, but it burns sort of so it's not going to stick around very long.

not likely. you'll get more a oil mist in the cylinders. not enough to cause a lock, but usually enough to give a cool James Bond style smoke screen as you pull over cursing.

Not so much. It would be difficult to get that much oil around the pistons even if the rings were GONE. Pistons tend to move pretty quick, and the clearances that pistons have would pretty much rule that out. The "leak" needs to come from a pressurized source(cooling system, hyperactive fuel rails or a turbo that has lost its mind).

Years ago...72? I had a friend who had a VW bug that smoked like crazy...

It left a heck of a smoke screen. His fix? He mated it with an inch and a half hose and ran it up the back of the bus to just over the top of the van....

Oh man.....was that ever funny to see going down the road. It looked like a coal stoaked montrosity...


Thanks for the memory boost...

One other thing what would be the symptoms? I guess one would be hydraulic lock. Would another be like rough idol and a-lot of vibration?

[The_Lurker]

Yep.

Top fueler dragsters run so much fuel one of thier biggest concerns is hydro(in this case nitro methane) lock on the cylinders. Each plug gets about 40 amps pumped thru it, melting them in the process. The engines are actually dieseling by the end of the run. To shut em down they cut the fuel.

a quick fact. top fuelers cannot run steel alloy HI PO rods. they will snap quickly.

they have to run aluminum rods just because they will give under the extreme cylinder pressures. ofcourse they don't last very long and are discarded frequently regardless of there condition.

Think about it.

Cylinder is not compressing the fuel. The piston is prolly skewed. So it's in synch movement wise, but the balance is all wacked.

What are the other consequences of havin low compression?
What happens to the fuel?
What happens to the exhaust gases in the effected cylinder?
Imagine the poor bent rod and attached piston zippin back and forth in the cylinder and make some guesses.

Probably. I've never experienced it but I expect it would be rough at any speed. Once it is bent, it will only bend further. It would not have to bend much to come in contact with the lower edge of the cylinder barrel. That's when things will break.

Incidently, I've had hydraulic locks with the old Ford carburetors when a leaky power valve drained fuel into the cylinders while not running.

its a piece of metal that spin's?
