Use the grooved cog with the grooved shaft to have *ALL* the oil!

well i got it all back together complete rebuild, new cams, tune and all. I put less than 20 miles on it and it started what sounds like a rod knock. Im really at a loss here considering whatever pieces of metal probably went through the new cams and everything else. I think i will abandon this thing for a while.

Sorry to hear that. You *can* pull the pan with the engine in the car to investigate, though.
mcfrandon OCT 05, 01:29 AM
yeah I decided to pull the pan and look at the rod bearings and the same thing happened that had happened the first time... spun the bearing on the cylinder 1... I dont get it. I changed the rod out and platigauged it, and it turned out good what the heck. Doesnt look like there was much if any damage done to bearing 2, and i have not looked at the others yet, and the crank looks fine.

Just pulled these out from cylinders 1 and 2 journal.




here was the worn out tensioner



how she currently looks



gotta love aluminum



here were the 2 bad shafts and sprockets, shows the different 2



i have a picture of the crank too but it wont let me open it in paint for some reason, ill try to get another tomorrow. the cranks looks unscathed

And that's what good bearings are supposed to do... If you're lucky you can drop new bearings in it and get back on the road... HOWEVER, you would be wise to split the case and clean out the oil passages from the filter to the crank.

That tensioner's beautiful. That engine must be shy a few oil changes.

Unfortunately i dont have the time to pull it back put, since i will be moving soon, so i will put a new bearing in and hope for the best. Both times the bearing went i was coming down off 6k rpm. I wonder if it ran out of oil or something, i know the oil level was toward the mid fill line. The first main journal supplies oil for the heads/intermediate shaft, and the first rod bearing or 2. Just trying to come up with answers to this nonsense!

You used pipe cleaners on the crank oil passages, right?
mcfrandon OCT 09, 01:51 AM
i cleaned the crank with brake clean and compressed air.

I also have some interesting leak somewhere around cylinder #2 exhause port that i cannot pinpoint




I was able to get the new rod bearings in tonight and get her all buttoned back up. it was well within range on the plastigauge. however after it warmed up the oil pressure still reads low at idle about 10psi at 1krpms. im thinking of getting a different oil pump. sure wish i didnt throw away the old one now. the noise is gone though.
