" MOST engines with street clearances will have at least 10-20 lbs at hot
" idle. Back when the GM3800 was known as the 3.8 they had the oil pump in the
" front cover a lot like the AMC. Idle oil pressure was a common problem with
" them and it wouldn't be uncommon to see them with the lifters bleeding down
" and LESS than 3lbs OP at idle!!! There was a high capacity OP kit for them
" which could be installed in the car which increased the OP capacity by about
" 20% and usually cured the problem. GM's answer was that unless the lifters
" were noisy, or the OP light was on, to install a new OP switch which didn't
" turn the light on until LESS than 3lbs !!!! (stock one was 5) It sounds bad
" but I saw many, many of these motors go 100,000 miles like that. 

those buicks, evolved from the 215 aluminum v8, have really small
bearings too, and even the 350 v8 still had the tiny 215 rod bearings.

afaik front covers were still the same up to the 3.8, too.  all the
same at rover too, who made the ex-buick aluminum v8 up until bmw took
them over early in the last decade.
