Settle A Bet - Land Rovers Only

A friend of mines 2nd car has developed a bad rod knock. It is Chrysler Concorde with a 3.3l v6. He says that if he pulls that rod and piston out that the motor will be fine. He says worst case he would need to pull 2 rods and pistons one on each side. He is also going to unplug the injector/s and remove the push rods from the area with out the piston/s.
I bet a $100.00 that it wont last longer then a month.

That's about the stupidest thing I have ever heard of, removing rods and pistons to get rid of knock. Crap, how hard is it to put bearings in, especially when you are already unbolting the rods?

It is pretty much a car he doesnt need. It has been knocking for a good month if not more so odds are the crank is shot and would need to be ground. I have been searching for more info on it. There is a company that does that to vw motors. They turn them into 2 cylinders for planes. You can get it with the full block or a block cut down to just the 2 cylinders. They use the air cooled motors.

If some bearings are gone, the rest are on their way. If you remove rods and pistons, the crank will be unbalanced, hastening the demise of the crank bearings. You will have to weld shut the oil holes from the removed rod(s) or the oil pressure will be even worse. Still the stupidest thing I have ever heard of.

Balance is the least of said idiots worries. It won't last a day. Rod bearings don't fail for the Hell of it, they fail due to lack of oil pressure. Without a rod on that journal, the engine will have a 1/4" pressure fed oil hole in the crank, and what's left of the POS will have no oil pressure whatsoever.

So it looks like I will have an extra hundred.

Well he did it. It runs surprisingly well. No nosie no odd vibration not much of a power loss. His oil pressrue on the aftermarket gauge is actually reading around 30-35. I still have faith it will fail with in the month. He said it is only a 20 min job to pull the oil pan in that car. He also said the crank is toast
