I put restrictors in the 3.0 when I first did the turbo conversion, and I also had oil problems, but those were specifc to my Rajay drain system. I have installed an 0.080" restrictor with a downstream needle valve in the oil feed to the turbo. I think it's kind of difficult to over-oil a Rajay.

Related to your comments, when I had the engine apart after the rebuild for ring issues, I didn't like the way the cams were scuffing in. I think it made the car run a smidge hotter also. So, I ditched the restrictors. I'll check the cams at the next valve adjust.

There is a pretty good thread about these restrictors in the tech forum, mostly written by Grady Clay.
