Last weekend I had some more time to work on the engine so I started by pulling off the masking tape from the block and cleaned up any tape residue from the paint job. After that I washed the block with some soap and hot water, and then quickly dried it off with compressed air. I then used a paint stir stick rapped with Bounty paper towels to clean the inside of the cylinders while I sprayed some WD-40 on the cylinder walls. I did this till the paper towels did not show anymore dirt from the cylinder.
As you can see in the image above the engine block looks great after some fresh paint. I dried the inside of the cylinder walls with paper towels and sprayed WD-40 to lubricate the cylinder and to clean out any left over dirt, dust and minor surface rust
After the block was clean I disassembled the pistons from the rods and washed everything thoroughly with hot water and soap. After everything was clean I assembled the pistons back together with assembly lube and put on the piston rings. When putting in the piston C-Clip’s make sure your using the proper C-Clip pliers otherwise don’t bother cause they are not easy to put in without this proper tool.
When adding the rings to the piston, I put on the oil rings first, the 2nd or middle ring next and finally the top ring. I just used my fingers to expand the rings carefully and made sure I didn’t break them. Once I was ready to insert the pistons back into the block I used an old clean toothbrush and carefully applied 30weight oil on the skirt and rings of the piston.
Once the pistons were nicely oiled up I used the toothbrush to apply oil to the inside of cylinder walls and made sure everything was lubricated for proper for piston insertion. I used a regular piston ring compressor to compress the rings and then used the handle of a hammer to bump the top of the piston down into the cylinder. Be very carefull and if the piston doesn’t go down after a few bumps, check to make sure your rings are compressed. I did run into one problem where the oil rings weren’t compressed enough and it was stopping me from inserting the piston into the cylinder. Now taking the ring location into consideration if the intake side being 12pm on the clock, I put the 1st ring around 11pm, 2nd ring around 5pm, the main oil ring about 3pm and the 2 other oil rings about 10pm and 7pm.
