Think it needs to come apart.
Plenty of 202's or on the tracks of oz using a standard style oil pump with no issues, in worst case seen the standard pump modified for external pickup.

I think you are on the right track mate. Dont name and shame at this stage- give them a chance to fix the problem.

 

Also, as a side note, never blindly trust that what a machiner has done is correct and accurate- they make mistakes just like the rest of us. One of the problems with machiners though, is that they also can seem ultra confident and tell you that ' it is right, your wrong, our work is always good, ive never had a problem in 30 years blablabla'... but in honesty, i have seen some MASSIVE issues caused by poor machining, or mistakes made during machining.

 

Ive had a block returned with the pistons sitting 2mm above the deck (I kid you not... and when I mentioned this issue, they said they had dummied it up  ). As soon as they saw this in person though, they were quite embarrassed... They massively over decked the block (big night out the night before maybe??). I have also seen them over bore/hone to way beyond clearances (triple to 4 times the spec I ASKED for). 

 

Every one of my engines that I have built has every bearing clearance measured with plastiguage, every cylinder measured to ensure its at the spec I specify and so on. Its an extra 15-20 minutes during a build, but think about how much money and time you spend building the whole thing, taking engine out and putting it back in, etc etc etc...

Always check.
