I was using a 4" PVC cap and got it about 1 mm inside the flange on the block. if you look real close, you can see that in the previous pic.
also LR told me the 'trick' to shorten the spring by 10mm to tighten up the seal around the crank end.
since you implied a foopah of some sort, I'll show mine.
I have a collection of short PVC sections for such issues. thought I would use one to seat the pilot bearing. idea was to avoid hitting the inner part with a hammer.
as I was tapping on the PVC, it shifted and dented the bearing seal a little.
got a new one to put in the normal way, tapping with small plastic hammer.
I have learned sooo much from all my mistakes. really try to not repeat any. good so far.
