hellothe later BRE engine has the oil pump driven by a gear not a chain so it doens't suffer the same issues as the earlier version of this engine its still prone to issues with chain wear though as the chain drives the balance shafts, however shoudl this fail then at least it doesn't stop the oil pump and destroy your engine what really helps extend the chain life is the use of a good synthetic oil changed at regular intervals ( every 8-10K)

Does this engine still need the oil pump upgrade I.e hex key and shaft
Expert:  Matt replied 1 year ago.
Hello no the BRE variant have a revised oil pump drive so the hex key isn't required as its geared directly to the crank
