removing and replacing oil spray bars from cam towers

[fredmeister]

I am rebuilding my 3.3 liter turbo engine and have removed the cam towers for cleaning. I would like to remove the oil spray bars and blow them out but they are captured inside by freeze plugs on either end of the cam tower.
QUESTION: what is the best way to remove these spray bars and reseal the cam tower?

I was thinking of having to drill out one freeze plug to remove the spray bar.
Then tapping the end of the hole for a small 1/8 inch pipe plug to reseal it after re installing the oil spray bar.

Anyone else done this job an easier or better way?

I dont think I am gonna find those freeze plugs anywhere, plus do I trust them to hold against oil pressure when I install them, a threaded pipe plug sounds alot more robust.

Thats how its done just be careful drilling out the plug, may want to start small and work up in size. usually when you get close the plug pulls right out.

Here's a thread discussing threaded plugs in the cam towers.
