[DeTomaso] Oil pressure help needed

[Christopher Kimball]

I've inquired about my oil pressure before, and some suggested since my motor is new, a bit higher than normal could be expected.

It's been over a thousand miles on it now, though, and it still seems pretty high.  It was suggested I check with the experts (read: you all) to see what the general consensus was.

The stock gauge reads 68 and Idle, and 70 (all the way to the right) under hard accelleration.  The mechanical gauge I installed a while ago shows about 60 at idle and 65 to 70 at normal cruising speed on the freeway.  When sitting idle, however, when I rev the engine the mechanical gauge goes to 85 at about 35000 rpms.

In checking the engine build sheet, it shows a M84AHV Melling oil pump.  I think the HV means high-volume, which, apparently, may not be a good thing.

How big of a problem is this?  Am I going to be happily driving to Reno next month, only to explode into a pillar of fire?

Thanks,

Chris
