I've got all the threaded plugs out of both heads, do I need to remove the oil restrictors, and if so, how?

Google has not helped me

 

Yes, always remove them to clean the oil gallery's and then refit.
And how to remove them ..........




















Drift out from the opposite end with round bar or similar
(head shown is Version 6 STi, so your restrictor may differ)

Top man!
Somehow, I sort of expected a reply from you.

 

Glad to help

Mick

 

all done, popped them out with a piece of 5mm aluminium rod, no bother.

 

What would we do without you Stranger Need to catch up soon.
