B275 compression leak around injector

Pulled injector cleaned seat twice everything looks great, still leaks, any ideas

Hi Mark, IRC, there should be a brass/copper sealing gasket on the injector and they had to be tightend down evenly so the seating surfaces were aligned.

Just looks like a silver washer, parts book is kinda vague

Mark, caseih.com parts:
B275 Engine Page 025 item 30 4 710383R1 GASKET GASKET, pre-combustion chamber, lower.

It has been 40 years since I had an injector out of a B414 but I recall the gasket being a copper compression ring like was on old spark plugs before the tapered plug was invented.
