My engine is appx 6 yrs old has less than 10 k on it its a mildly built 455 oil pressure is 15-20 at idle but goes right up to 40-60 depending on rpm. Always been that way. I run synthetic 10-40 always have. I have the feeling somethings failing on yours of course I am sure you know that. No other indicators though? Noises? Anything?
My oil pressure started out 20 lbs at idle and goes right up like yours. I also use 10W40 syn. I've had the engine a couple years. just got my convertible on the road this summer for the first time. oil and filters have been changed 2-3 times since being on engine run/test stand to car. oil and filters are fresh. I've only put maybe 100 miles on 428 so far this summer. Something is failing. engine was rebuilt when I got it, don't know who or machine shop that did the work. I did have some work done to RA#12 heads, hardened valve seats, valve job, etc. I can see that engine has new pistons, etc. Looks like I'll be pulling 428 soon. Have a rebuilt stock 350 to put in for rest of summer. I had flywheel resurfaced but not rebalanced. think I should get it balanced ? I'll have 428 ready for summer 2012. will be a Tremec 5 spd behind it then.
