THE BLOCK


The Engine BLOCK is the foundation on which the engine is built. The block must be free of warping and cracks for parts to function properly and not wear excessively. The cooling system, oil ports, internal surfaces must be CLEAN !


OK, So now you have your engine out of the car and on an engine stand and the heads are removed and the oil pan is removed.

This thing don't look so big and bad now. With some of it's parts removed . Does it ?
Well let's get to removing the internal parts of the engine.


Before pulling the piston you must remove the ridge inside the cylinder wall at the top. This is called a ring ridge because as the piston moves up and down the rings wear the cylinder walls . And if you'll take notice there are no rings within the first half inch of the piston.
To take the ridge out you should use a ridge reamer.
Take a look at the pictures to the right to help you understand ring ridge.

I don't have a picture of a RIDGE REAMER yet but I'm looking for one.


In order to remove the pistons from the block you must remove the end caps from the connecting rods that connect the piston to the crankshaft.

Before removing and end cap bolts on the connecting rods make sure that the end cap and the connecting rod are numbered for the cylinder that they should be in. And all numbers are facing the same way for each bank of the engine.

If the end caps and connecting rods numbers don't match each other or there not in the right cylinder put them in the right place when you put them back in the engine.

The right piston in the right cylinder and the end cap is on the right connecting rod and that the numbers are all facing in the proper direction. (usually they face to the outside of each bank if it's a v6 or a v8 an inline engine check the repair manual for that engine)

As you will notice when you take the end caps off the connecting rods the will be what is called a connecting rod bearing in the end cap. (the bearing in the end cap is the bottom half and the top half is on the connecting rod)

This is the part that takes all the wear. You'll probably see nicks marks etc. These bearings are made of some type of soft metal like copper etc.
