2002 ford iveco cargo oil dipstick and pressure

Anybody familiar with these 7.5tonners

The fill point is under the hatch but where is the dipstick, can’t see it anywhere even when jacking up the cab couldn’t see it

Also
How does everybodies oil pressure sit… mine sits arou d 2 bar on idle, raises to about 4 on revving and maintains such under driving, until you dip the clutch or hit idle speeds again it’s drops back down… I’ve never noticed it before so is this normal for these or should I be expecting a steady 4 bar at all speeds?

red rubber ring under hatch near the filler. pull it, that’s the dipstick.

oil pressure at idle sounds normal to me.

Thanks. I was completely blind, found it this evening. Right next to the fill hole.

Tonight was sitting about 1bar ish idle, but reading about I see loads of things saying this is normal as you say it is
