R33 Rb25Det No Oil Supply To Cylinder Head

[zachdani]

Engine was rattling - found there was no oil supply to cam or lifters

Removed head to find that there is 3 oil feed passages to the head and the rear passage is blocked

Can you remove the restrictor plugs and can you buy replacement plugs so I can try and clean the passage - have tried to blow high pressure air through but won't blow through.

Any have a similar issue or any suggestions?

sounds like you need to do more than just remove the junk. Blowing air into it, where do you think the blockage will go?

The plugs are able to be removed, but not easily. Try tapping them and using a slide hammer (the gallery is already full of shit so drilling and tapping wont matter) However, I would be pulling the whole engine apart or getting another.
