Thread: question on main bearings

Tweet

Hey Edmontonian,
We are going to kick your butt on Saturday night, hehhehe! Canucks Rule.

Anyways, if your main bearings are spun, there is a remedy. It is called, “line honing the mains” which will cost you about $185.00.

If you remove the oil pan and along with all the main bearing caps, you should notice that one of the bearings will not be in it’s place. Each bearing has an ear which is supposed to fit into a relief. Both the block and the bearing cap have a pocket for the ears of the bearings to fit into. If they are sheared flat, this tells you that the bearing has spun. Also if you take notice of the metal in the one journal area of the block, it should have scratches and shiny metal in comparison to the other areas of the four other bearing mating surfaces.

It is always a good practice to line hone all high performance blocks to ensure quality, so in essence, no money is wasted even if you bought a block with a spun bearing. Chances are you will get this block for free or maybe $50.00 , yes? Whereas a good block (one without a spun bearing) you might pay $350.00 for it.

Having said that, I was just offered three 350 ci blocks with spun bearings for a total of $150.00. All blocks were of the newer version with one piece rear main seals. One block was a roller block with four bolt main, the other was a 2 bolt roller block and the last was a none roller two bolt main.

Yeah, so put your money on the Canucks and when the game is over, you will be able to buy a crate motor with your earnings!
