Bummer deal! Your motor knocks - deep in side. Your told by your mechanic a rod bearing has failed.
What you should know.
Your motor has two types of bearings on the crankshaft.
One set of bearings holds the crankshaft in place so it can spin the transmission gears.
The other set of bearings, called rod bearings on the crankshaft are connected to your motor's pistons.
Combustion part in all this.
Hundreds a time each minute combustion occurs on top of your pistons and slams the piston downward causing the rod to spin the crankshaft - and transmission and wheels - speeding you down the road.
About 45 pounds oil pressure forces oil into the tinny space between the crankshaft and bearing on the rod. This works well and seldom is ever a problem. However.... some of...
Your motor combustion likes to sneak pass the pistons and mix with your motor oil. This is no good of course. This condition is called BLOW-BY, and happens with every combustion action and no harm is done - unless the piston rings become sticky.
Combustion turns into harmful blowby
They do around 100,000 miles more or less, and sticky rings will allow more blowby- at over 1000 degrees temperature and that will tend to sludge your motor oil.
Blowby makes sludge and sludge causes the knock
Sludge from blowby will usually stick your motors valves and valve adjusters and make them tap. But, sometimes, a lump will form, circulate, and block oil to your rod bearing.
Blowby has lots of unburnt gas or diesl fuel in it and this increases weakens the oil film strength increasing friction and wear speed. With friction and sludge, when that happens....
Wear out accelerates, and friction grinds away the bearing and the crankshaft metal - increase the space to 1/8 of an inch and - the slam down on the piston by combustion on that new space makes the knock knock knock sound.
The real remedy for your knock
Mechanics suggest a new engine or engine overhaul.
That means new internal parts for about a $3000 or Close to $5000 for a new engine.
Some people prefer one of those thick gluey oil additives - but this seldom works as some feel their gluey like nature slows down oil delivery and speeds up wear elsewhere - where thin oil can only work.
Mega Power's multi-method to reduce oil knock - under $100
Sticky residues put a strain on all engine parts.
Shown here, the 6 Mega Power Treatment to reduce rod knock. 3 items clean and condition the top side of your motor, and 3 do the need conditioning in the lower part - where the troubled rob bearing is located.
The Metal Canister is used to make the Mega Power install while the mechanic is doing other work nearby. Not included. Just $125 for the canister, if wanted.
Mega Power also adds a co-polymer film that layers itself over worn surfaces. This on the piston and cylinder also reduces blowby.
