D-a-n-i-e-l Posted March 4, 2017 Share Posted March 4, 2017 Anyone know what would cause this? Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted March 4, 2017 Author Share Posted March 4, 2017 I didn't find any blockage. The rebuild had about 1000 miles on it. I am replacing the crank and all the bearings. I can't figure out the cause thus far, so it is a bit of a gamble. The whole engine block was gone through by a shop prior to the rebuild. I am kind of lost on this one.

padgett Posted March 4, 2017 Share Posted March 4, 2017 Have found blocked oil passages in a "newly rebuilt" block before. Long pipe cleaners are your friend. 1 Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted March 4, 2017 Author Share Posted March 4, 2017 The rod bearings were worn in a pattern that indicates they didn't go back and repolish the crank. I replaced them 18 months ago and put on 150 miles. The rod bearings looked great when I pulled them this time. I did not pull the mains when I did the rods bc the engine was still in the car. I doubt there is much in the filter as the oil was clear, but I will check also I will drag the oil passage before I put the new crank in. Once I get past this I will probably do a write up on the F40 series two swap. I have something I don't think anyone else has done and hopefully helps a few that have or will do the swap weather it is in a Reatta or other car. 1 Link to comment Share on other sites More sharing options...
2seater Posted March 4, 2017 Share Posted March 4, 2017 Are main studs standard on the Series II? Does it use the same oiling system as the earlier version? How do the rods look? 1 Link to comment Share on other sites More sharing options...
2seater Posted March 4, 2017 Share Posted March 4, 2017 Was this block line honed? If the rods look good, they must be getting oil from the mains in the crank. Doesn't really look like an oiling issue, but too tight bearings or misalignment maybe? 1 Link to comment Share on other sites More sharing options...
2seater Posted March 6, 2017 Share Posted March 6, 2017 Was the flywheel for the stick conversion balanced to the Series II supercharged spec? Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted March 6, 2017 Author Share Posted March 6, 2017 Yes. The whole rotating assembly was balanced. Link to comment Share on other sites More sharing options...
