Dipstick

[JGeezer]

Can someone verify this is the correct twink dipstick? There is about 10 1/2" from the tip to the stopper. The stick hits the sump bottom before it is all the way into the tube, confusing me a bit. Perhaps the dipstick tube in my unknown history disassembled boxes-of-parts engine is wrong.

Thanks!

Seems to be a popular topic at the moment!

My dipstick (with 105e-6752b part number) measures 26cm from the very tip/end to the bottom of the stopper, 24cm from the "fill" line to the stopper, and 22cm from the "full" line to the stopper.

Confusion over whether the dipstick and tube is correct can cause problems but as long as the engine has the correct amount of oil in it you can then take a reference point with anything you like and provided you use that as your reference your oil level can always be checked/referenced accurately.

In one of my cars I don't use the correct dipstick, I just make sure that it has the correct amount of oil in it and check where that comes to on the dipstick. Not had a problem (yet!!).

As part of my Winter rebuild I intend to drop the sump,measure where the dangly rotating bits go and set the oil level just below....will take measurements and post them later.

The dipstick is probably hitting the baffle.

The stick appears to be the proper length, so that could be. What should I do about that?

Does the dipstick have a tube for it to slide into or does it fit straight into the front cover?

Either the tube is too far in, or the tube is non-existent. Do you have a photo of the dipstick in-situ?

Something else to consider, do you have the correct / factory sump fitted ? - if so has it been damaged on the underside, has someone tried to jack the car up on the sump bottom ?

I'll get a pic, but the stick hits an obstruction with 25-35 mm left to go. It can be pushed past it, and will then seat fully.

The pan appears to be correct (or at least had been on there for ages, judging by the perished gaskets) and undamaged.

I will be pulling the pan just to find what's going on. Maybe the oil screen...?

[JGeezer]

The dipstick tube protrudes about 2 3/4" (70 mm), but it does come out at this odd angle. Is this normal?

and the sump does look fine...

Mine occasionally hits an obstruction when inserting the dipstick. The engine is as it should be re dipstick tubes and sump.

I simply remove & twiddle & re-insert until it seats ok. I think there's very little clearance at the base if the dipstick is not put in with the right orientation.

Or maybe it's just me ??

Does your dipstick tube have that odd angle to it? (Hmm, that sounds rather personal, sorry).

More importantly, can any of you who do not hit anything take a look at your dipstick tube angle for me? Maybe richardcox_lotus and I both have the same problem.

Yes, that sounds about right from your description. As long as it goes all the way in, there is not much you could or need to do, that is just how it is.

I have one that does and one that doesn't. Be aware that if you straighten or start adjusting things the dipstick will rattle.

[JGeezer]

OK, couldn't STAND it, pulled the darn sump off. Had to figure this out, I could not accept the dipstick crunching into something. Who knows what I did wrong.

If you, uh, look at the earlier pictures you'll note the engine is now in the frame, but the head is still off. So the DAMNED TIMING CHAIN IS LYING IN THE PAN at the moment.

As I put the pan back on, especially as I fiddled with those two rear bolts, I thought how nice it was that I would be giving all you guys such a good laugh. And thought that again as I snapped off one of the front ones.

Sigh.
