That's right. I pulled the 350 out of my 85 Z28 (not original) because of a knock. I knew the knock was there when I got the thing, but I just could not pass on the price...
ANyway...
When I pulled the oil pan off, I noticed that the #1 and #2 rod caps were black. Looks like they got really hot. This will be only the second time that I have rebuilt a motor, so I am not sure if I need to buy new rods. Don't want to incur the expense if I don't need to. From what I can gather, if I have work done to one rod, I need to have work done to all of the rods. Is that correct?
I plan on taking the entire motor down and doing an over haul. There were quite a few metal shavings on the oil screen, so I figure it could not hurt. Sure hate to buy new fasteners, but better safe than sorry.
So, any insight as to what to do with the rods? Should I fix the ones that I have? And, what causes the 'blackness'? Did the previous owner drive it too much after the bearing spun?
Thanks for your thoughts.
