Title: Rod journal marks. Post by: Taylor on July 02, 2013, 11:06:54 am Late night question for everyone. I took the top end of my motor apart because I found some aluminum in the filter. Everything looks better than I could hope for, even the oil pump. The rod bearings don't look bad but I'll replace them anyway. To my question: the back side of the rod journals have some marks on them. They don't look that bad and I can't feel the marks. My question is what would cause the marks to be only on the backside? If something went through I would think the marks would round the circumference. The marks are lines consistent with debris going through. Maybe it was the 24 dyno pulls.

can you put a pic up so we can see exactly what you describe? cheers Richie Title: Re: Rod journal marks. Post by: Taylor on July 02, 2013, 11:15:21 am I could maybe tomorrow, but the crank is still in the case and I can't get a good picture.
Title: Re: Rod journal marks. Post by: richie on July 02, 2013, 11:35:01 am Ok, do you mean the underside of the crank on the rod journal? how do the cap side rod bearings look? worse than the rod side?
Title: Re: Rod journal marks. Post by: Taylor on July 02, 2013, 11:38:43 am Maybe a little worse. So at top dead center, the part of the journal that is marked is the cap side, like you say.
