So I decided to clean up my original engine while I run the car with a modified scat engine.
When I drained the oil I found these....two small pieces and the nut.....(dime for size). So I started to tear down the top end and found one cylinder that looked not so good. The others are the same as the right side. went down further and removed the pistons and am now cleaning them all up. Everything looks ok. I really don’t want to split the case or go any further and from what I see inside all look good. So two questions.... 1) any thought on why this cylinder isn’t firing right ? 2) can I use something like gasoline or similar to flush and clean out the inside of the case with the crank and oil pump etc still attached? 3) any reason why I can’t use all the old parts ? 4) any thought on the nut? Thanks.... |

So I am now starting the rebuild after the tear down, cleaning, new parts, testing, etc....One question, I am putting in new barrels, pistons and cam, pins, bearings etc, but keeping the original crank which was tested and is in good shape. In addition, all 4 crank rods checked out. However, I assume I should replace the 4 round bushings at the small end of the rods. From what I have read, this isn't a do-it-yourself home job, but instead should be done by local machine shop. Am I correct?

Yep not DIY,I have found these stand up fairly well but with piston pins worn on cold start you hear a noise like ticking it soon go's away after the engine warms up. The new lubed piston pins should be a firm push to pass through the rods. Best to replace,EMW have speced rebushed rods for a great price ,last time I checked it was $55 for 4...excellent value from a good shop and most likely cheaper than the small end bushes to fit and ream somewhere else. |
