Rebuilt D7H engine oil level problem

Hi vetech the head gasket will only fit as intended hi chidog rear seal was replaced I have had what you describe happen in the past but sure it’s not in this case the trans oil runs clear as in these things the black oil would show up quite easily on the trans dipstick it’s so clear it’s quite difficult to get a accurate reading have to rest the stick on the end of my nose just about

Have you ever changed oil and added what the service book called for checking the gauge?
When you check the oil hot do you add oil?

Has it got the right dipstick, just a thought.

Good thought about the dipstick by the above poster.
Fortunately,the chap has other D7’s that he can check with on site.
That said,wether it’s the right dipstick or not,the oil is still jumping about somewhat.
It’s definitely worth checking though half an inch in the wrong direction on the stick could mean a gallon of oil in the wrong direction in the sump.I guess if it was well overfilled it could give false readings on that stick if it can never quite settle right.
I’ve just ordered my new dipstick tube from Cat for the D9 this morning.As a precaution,when I fit it,I’ll just compare the dipsticks with the other D9 to be sure.

As a side thought,had anyone fitted a new dipstick tube on a C18?
I’ve only been able to take a rough look without dropping the belly plate and it appears to be pushed into a hole on the block.
My chap in the office that sent me pics is now caught Covid,so I’ll be getting no more looks at a service manual for a while.
I’ll post some pics when I get around to doing it

These are best pics I can get.
I’m not really qualified as to how that actually inserts into the block,but it’s feasible to consider that the OP has been into this area when rebuilding his D7 and possibly disturbed something in the orifice.I’m thinking that a piece of blue paper,rag fragment at this point?
It’s a long shot,but if everything else has been done to his satisfaction,it’s worth a thought that the trouble could simply be in reading the oil level.
As another poster here said,it’s worth putting the absolute exact amount of oil in that the manual states.
My D8T supps 34 litres according to the manual.I allways precisely measure the amount that goes in upto 33 litres,then check things as they’ll be some residual still in there somewhere.
Back in the day,I’d simply chuck four 2 gallon buckets into the D342 D8’s and they would be near enough for my taste,but I’m very strict on not overfilling the C series D9 and D8 engines.

This is the abortion of a dipstick I currently have stuffed into the D9.I’m ashamed to say that I’ve had it over a year and not done anything to sort it out as the D9 was supposed to be a short term thing.I’ve ordered the tube for it and will remove the belly plate and take a good look in there as I’d like to see what’s underneath that rubber engine moulding.There’s oil getting out of the block somewhere next to the starter.It’s not critical,but I’d like to take a peek when I fit the tube.
Does anyone know what’s begind that rubber cover thing?
It’s a D9T RJS series.
Thanks

Yeh Rd it has the correct dipstick the engine oil capacity spec is 27 litres
While the pan was off I took a series of measurements to give myself a better picture of my concerns,with 1/2 of inch oil on the stick there is still 2 1/2 oil in the pan that’s eased my nervous level ! Then I look at the shape of the pan it slopes at about 45 degree front to rear both ends hmmm, that 2 1/2 inches of oil in the pan would be less than 10 litres possibly as little as 7 litres wow that a lot of oil in transit All of these measurements improve slightly as the engine temp rises then when I shut the engine off it takes 8 hours to record full level on the stick again I will be like Nicky soon and need a new dipstick I’ll have worn my one out

Fair play
You’ve given it your best shot it getting to the bottom of things.

my thinking now is cut 2 inches off the end of the tube at least I then can be sure of a better contact with the oil and hopefully a more accurate reading

If you do this, there will be no more checking the level at idle, the oil being splashed about will be all over the stick, unless the marks will still be in the tube? In which case, carry on.

My 3306 PC engines have 2 inches of stick out of the tube and they give an accurate oil check at idle so I have no worries there,DI and PC engines are identical in pump and sump department
