What happens when rod bearings are to tight?
When rod bearing clearance is too tight the end result is what is called a spun bearing -- definitely a bad thing. Bearing clearance is the difference between the inside diameter of the bearing and the outside diameter of the crankshaft journal to which it is clamped. The bearing is supplied pressurized oil fed by the oil pump, it should never touch the crankshaft journal but should always float on a wedge of oil. If the clearance is too tight the bearing touches or drags on the crankshaft journal and the journal grabs the bearing and spins it inside the housing into which it is clamped -- which in the case of a rod bearing is the big end of the connecting rod. Once this happens it all pretty much self destructs as it chews up the big end of the connecting rod and the crankshaft journal as well.

Asked in Transmission Fluid, Chevy Cavalier Z24
Can a bad bearing or rod be fix with transmission fluid?
I wouldn't think so. That would only thin the oil even further and possibly damage other parts. The only fix for a bad rod bearing is to check the crankshaft for damage as well as the rod and measure the diameter of the journal for out-of-round conditions. If you are lucky,you may just replace the worn bearing...but most are not that lucky and I wouldn't advise it. When a rod starts knocking, it's like hitting the crankshaft with a hammer and it will wear the sides of the rod cap/crank journal until it gets so much play, it breaks the rod,rod cap or piston..hence the saying "Sling a rod".

What is the formula of area of a rod in length and radius?
Which is stronger solid steel rod or hollow steel pipe?
By stronger, we need to define the loading conditions of the rod or pipe. The strength of a rod or pipe is typically evaluated with axial, transverse (bending), and torsion loads. With the same diameter and the same material, a solid rod is stronger than a hollow pipe. However, with the same weight and material, the hollow pipe is stronger than a solid rod. Because a hollow pipe is lighter than a solid rod at the same diameter, the hollow pipe would have a larger diameter in order to match weights with the solid rod and a larger diameter rod or pipe is stronger than a smaller diameter one.

Why are crankshafts counterbalanced?
The weight of the piston, rings, and connecting rod is concentrated out at the rod journal. As the crank spins, it throws that weight around. The counterweight is on the opposite side from the rod journal to offset this weight. This is why when you replace pistons or rods, the crank is rebalanced by adding or removing material from the counterweight.
When talking about connecting rods for a 350 engine what is meant by small journal or large journal and how do you determine which is which?
New answer- A small journal has 1/2 in. Rod nuts A large journal has 9/16 in. Rod nuts A previous comment was "On The Engine There Is A Large Journal This Is The Crankshaft Journal That Is What They Must Be Talking About. Where The Rods Go Is Call The Small Journal. This Is The Only Way It Can Be. Hope This Helps" I will presume that this question is not about the difference between 'big end' and 'little end' of the connecting rods. Use of the word 'journal' indicates to me that the question is about big-end bearing size, not 'which end of the rod is which'. Technically, of course, the "journal" is the part of the crankshaft on which the bearing in the big end rides, but the measured difference between journal and bearing-bore spec would be little more than the thickness of an effective hydrodynamic lubricating film. Presumably this question concerns the GM 350 Chevy engine; look here for more specific information: http://en.wikipedia.org/wiki/Chevrolet_Small-Block_engine (Other related wiki pages related to specific GM small-block designs exist too). There is specific information on the different journal sizes -- ISTR specific mention is made, with dimensions, of at least one version of the engine that has different crank-journal specs depending on year. To answer the specific question, the 'definitive' way would be to remove one of the rod-bearing caps and push the rod up sufficiently to get a measurement on the crank throw. Measure the crank journal diameter at several points (to eliminate some of the effect of wear), then compare this to the tech information. I believe there are ways to tell from the engine serial number, but I do not know that information personally. Hope this helps properly... Small block engines (other than 350) before 1968 were small journal (2.00 rod journal). 1968 engines (other than 350) could be either large (2.100 rod journal) or small. After 1968 all small blocks had large rod journals with the 400 having larger mains than the others.
