Thanks. I think this is it. I missed a top bolt. The Haynes manual says there are 6 bolts in the bellhousing and 2 bolts additional to mount the starter. However, the photo link here clearly shows a 7th bolt hole in the bellhousing, which is one of the three top bolts you mentioned. I removed two of the three top bolts. I suspect I missed on of the top corner bolts. The M50D-R1 had 8 not 9, but the R1HD has 9. THANK YOU to all who posted replies here. And Yup, there are two dowel pins, but they are blind pin holes so cannot get PB blaster to them. When I re-assemble, I will lightly coat them in anti-seize.
