Just started my '87 300D for first time today; 28 hours since I shut it down
yesterday; 'best I could tell, it took about 4 seconds for oil pressure to
go to 3 bar after start and at idle. I'll try that and the '91 350SDL again
tomorrow. 'Think this has been mentioned before - if your oil filter
canister is the type with the small pipe down through the middle of the
filter, next time you change oil and filter, be sure to put new little
O-rings (2 on mine) on that center pipe and make sure the little hole in the
side of the pipe near the top of the pipe is clear and air/oil can flow
freely through the little hole and down the pipe.

Hello Wilton; I'm baaaaack !
It seems that from a stone cold overnight wait, it's about 5 seconds from
the time the engine starts until oil pressure is shown on the dash gauge.
During that time the engine makes little metallic tapping and clicking
noises.
From a 1 hr rest period and a semi-warm restart, it's more like 1 second
from the time the engine starts until oil pressure is shown on the dash
gauge.
I haven't had an opportunity to restart after a real road trip and a rest,
but I can tell you it's slow, and the engine makes larger metallic tapping
and clicking noises, which some have dismissed as "timing chain rattle,"
or something like that, until the dash gauge indicates oil pressure.
These noises are big enough that my son the race engine builder was
impressed by the noises.
I'm sure there can't be a whole lot wrong, because I can cruise at 80 mph
all day (I don't like to drive a whole lot faster than that). I have
almost no noticeable oil consumption. I have driven the car at indicated
105 mph and it had some left. Total indicated mileage 155, 7xx miles.
Mileage driven by me 31,000 so far.
Thanks for your interest. I'll be interested to see what you think.

Hello Wilton
Good question, I suppose. Right now all I can say is "Long enough that I
think it shouldn't take that long."
I will try to time it the next several times I start up and will furnish a
number as best I can.
Thanks for your interest. Robert

So how long DOES it take to go 3 bar from cold start?
