Hey Steve,

Geeze ya, I guess I should be more specific when I mention solder, but silver solder works fine and less fiddling than plugs, press fits and more solder.
You can even use left over babbitt. Tin the elbow and melt some in.

From Rob's posting:

'To restrict the inlet elbow you can either solder up the hole (in the elbow) and redrill a 5/32 hole or machine a small plug to press fit and redrill.'

Soldering sounds a good idea. My only concern would be, as it's relatively soft, I wonder how it would stand up to long term use. Would it wear away, thereby enlarging the hole and causing pressure drop? And if the solder did wear in this way, where do the worn off bits end up?

If you use a pressed in plug remember that the oil pressure will try to push it back out of the elbow and if it manages to do that there is a chance it could block the oil flow all together.........

For the non-engineers amongst us, Rob's 'press fit' means it should be tight enough to stay put. I would recommend a 'belts and braces' approach - a (tight) press-fit plug pushed well into the elbow, below the end and then solder a fillet in the angle between bush and elbow.

Ken's posting includes Otis' reference to 1/8" hole. For those who perhaps haven't realised, this is the same hole. The Henderson sheet refers to 1/8" for 'regular' use, 5/32" for 'racing' use. Bet there aren't too many of us who go for the 1/8" hole..... ;-)

The only other thing I would recommend is to fit a filter. I know both Rob and Ken do this but as they didn't mention it, thought I would.

Happy New Year to all - Steve
