I drove 160 miles Wednesday trying to seat the rings. I used 3 1/2 quarts of oil. I would have made a Navy destroyer proud.
So, today I went looking for reasons. There was a small leak at the oil pump so, I resealed that and a little oil on the bottom of the oil filter. Neither could explain my oil consumption so off with the heads (and PCs too). Attached image(s) |

Crosshatch pattern was set up and left from the Nikisil platers, just like the other 60 engines I have built with Nickies- No changes there.
I am confident the fuel washed the lube away early on, wore the rings and things went down hill from there. He has experienced .005 ring wear since the engine fired up, thats mopre than it should see in 40-50K miles IMHO Those rings don't really wear at all in the Nickies, something acted as a catalyst- no doubt and I bet it was all the fuel... As for the oil in the ports- Whenyou have that much oiland crankcase pressure is boosted on cecel/accel the oil will find its way through. |
