Hi Chris Sorry to see you have had the car damaged. There is no shortage of D heads in this world unfortunately!
I haven't been on here for a while and David told me today. Too many things going on!
I must admit to being a bit demoralised by the lack of dipstick replies!
I also have to apologise for the lack of reply regarding the dipstick pm. Thanks for trying for me. It should be ok though as I have gone somewhere in the middle at this stage.
Nick

Thanks for the HELP heading, and the info Chris. Hopefully I can get some MK3 info form other readers. In an effort to not confuse things myself more, I may need to re-post so that I am using the same naming as you. Just to confirm this is what you mean a picture. I have also found the OZ dipstick for the MK2 YD engine, and it is identical to the MK1 in all respects. There is a slight complication with that, according to the Oz Gregory's WM, YA is an auto engine and this one is sitting on a manual box. It therefore does not confirm 100% the manual OZ Mk2 if you believe the WM! With OKR, I loosened the tube nut and lowered the tube about a centimeter in a effort to get the oil quantity to about 8 litres. I consider this a safer starting point. The measurement was somewhat upset because some idiot forgot to tighten the sump plug, resulting in a big slick of oil on the floor overnight! I will have to drain the oil now if I want to check the quantity exactly. Oh well! What is your feeling on this subject? Does it really matter that much up to a point? Is it just because they are useless? Is there legitimate reasons for the number of different lengths? I am leaning towards this. There is quite a wide range where it makes little difference. Other than there being a larger or smaller quantity of oil in the gearbox. The ute engine, which would likely work harder due to greater weight, has more oil it. This makes sense to me. Oz conditions ie hotter and worse roads, more oil is beneficial I would think. Obviously up to a point! This helps to explain the wide variety. Incidentally the Oz Gregory's manual quotes a with filter oil change at 7.38lt. From the numbers so far I am going to make a conversion that should compare apples with apples! OKR Shoulder to MAX mark 461mm Current Tube height now 290mm 461-290 = 171mm So 171 mm is the section that drops from the top of the tube nut into the sump. Because I have taken off the tube height this is now constant figure which will allow a direct comparison. If I do the same sum with all the different engines as below you can see what I mean hopefully! OKR (300mm Tube height) = 161mm to Max OKR (290mm Tube height) = 171mm to Max Red Dog = 189mm to Max Eugenie = 190mm to Max Oz Mk1 = 185mm to Max Oz MK2 (Auto ?) = 185mm to Max Oz Ute = 165mm to Max The lower the number the more oil in the engine, so the Ute wins at 165mm. I would not venture below this number as it is the most oil in any of the factory setting so far. Unless another MK3 owner gives me some numbers. I suspect my tube height was not correct to start with. The tube was bent up, so I straightened it and this may be the source of the bad adjustment! Nick

Oh dear oh dear!
So I think OKR (Mk3)is almost identical to Chris on the dipstick side.
Metal blade only = 457mm Neck to low mark = 473mm Neck to High mark = 461mm Neck to tip = 482mm But the tube is wrong on OKR at 300mm rather than 270mm.
The tube height is what I need clarification on.
Oz engine 18YA/RC/H (Mk1)
Metal blade only = 447mm Neck to low mark = 464mm Neck to high mark = 445mm Neck to tip = 474mm Tube height = 260mm
Oz engine 18YF/Ta/H (ute)
Metal blade only = 425mm Neck to low mark = 445mm Neck to high mark = 425mm Neck to tip = 454mm Tube height = 260mm
Notice the Oz tube is consistent at 260mm. This is an important measurement as it can be altered because of the olive arrangement.
I have an Oz Mk2 18YD/Ta/H but can't locate the dip stick at present unfortunately.
More numbers required for clarification and hopefully we can get it into the tech section.

Thanks Chris and David.
Chris from how I understand you are measuring, and the way I read my WM you have a 457mm dipstick. The WM says dipstick blade measurement 457mm. If I measure just the metal blade mine is 457mm. I can't see this is a coincidence. If I measure it your way, I get 483mm so basically same as you. That means as I get 300mm on the tube that could be my issue.
It would be good for a couple of other readers to confirm what they have. Please!
I will measure the Oz dip and see what that is.
No wonder they had issues. The other problem is the tube has an olive to secure it, but if you move the olive the tube sits at a different dip length!

Could I please get a couple of you to give me a measurement from your MK2 cars. I think I have an oil level issue, as I just put in nearly 9lt of oil in to get to the high level on the dip stick. This was dry and included the transfer case but still seems too much. I have a 457mm dip stick blade. Could you please give me a length of your dipstick tube. Thats assuming you have a 457mm dipsick blade. Probably easiest to get a piece of wire or non stretchy string and offer it up to the tube. Hold the end of the measure on top of the nut next to the tube. This is the nut that holds the tube into the block. Then measure to level with the opening for the dip stick. My one is 300mm. Thanks in advance guys. It is a little awkward sorry! Nick

Getting there with the engine! I am just trying to sort out the dizzy so I can put that back on and I am back into the body work. I even found a badge to go on the rocker box cover. It may be unique. Nick

Be good if it works. Nick No idea what the results will be so it may be a waste of time. I can tell the difference between A-Series cars with standard thin steel and thick cast alloy aftermarket rocker covers, you may be pleasantly surprised!

Thanks David Sorry I was ambiguous saying about the 1800S dizzy. I do not have an 1800S dizzy, I plan to put one together if possible with the units I do have. Not an easy task it seems! Im hearing you, the future plan is an electronic adjustable advance curve. For the moment, for safe running of the car, I need a serviceable unit that is somewhere in the ball park so as to not hurt the engine. From your advice I can see the standard dizzy may well hurt the engine should I happen to give it some beans! I had been unable to work out what the advance numbers mean on the vac units, so that is very helpful. Typically the 4-11-7 unit I have seems to be jammed! Will use the 4-12-8 as it is the closest. With regards to the springs, the advance curve is not as steep as standard so stronger springs? I can see I am going to have to make something to test what is going on with the springs. If I use the 10° cam I have, that gives me 20° crank max, plus if I set the advance to 10° the total max is 30° so a conservative max for this cam? Sorry alot in there thanks for the help David. Nick

Ok I am at the stage of putting back the distributor, and after your thoughts about my cam with regards to timing David, I am thinking about what I need.
The old dizzy is a 41234A. It has a 15° cam and a couple of reasonably thick springs. It is also faulty by the looks of it, as it will not rotate all the way to 15°!
Anyway I have a selection of different 25D dizzys. I think I should start around the 1800S config, so I am thinking of a mix and match to try to get close with what I have.
In the mix I have 10°, 13° and 15° cams that I have found so far.
I have a 41234H in good condition but it is nothing like the 41234A above. It has a 10° cam and a very light primary spring.
I also have a 40770A and a 40897E and an Australian 29D 62941054A. I think I have a hitachi somewhere too.
So can anyone tell me to start with would it be an 11 or 12° cam in the 1800S 41238 dizzy from my reconing. Also what springs might be best.
I have a number of vac advance units as follows.
4-11-7
4-12-8
5-12-8
5-13-10
6-14-8
The one on the original dizzy is too rusted to tell what it was. Anyone tell me how the vac advance figures relate would be helpful too.

No nothing as elaborate as that David. The design is purely governed by space and avoiding clashing with the rockers. Underneath there is a course stainless steel wool pad for damping and the aluminum holds that in place. In actual fact, now I have put a camera inside for a look at the space, I could have extended down the valve spring side too. No idea what the results will be so it may be a waste of time. Nick Hi Nick An interesting mod. Did you develop the design yourself with NVH software - I have not seen anything like that before. David

Yes well I couldn't get the black I have been using so decided to go RED like the car! As for the question, I could be smart and say "The inside of the rocker cover!" That my friend is a small mod, as you might expect from me, that I hope will damp out some of the valve gear noise that the B engine makes. I already made a good reduction in noise by fitting the shims under the two middle posts. I hope this will cut out some more. Can't say I have seen it tried before, but hey nothing ventured and all that! There are a couple more small things. I found a tip online that says stick the cork to the box with a bead of silicone gasket sealant. It is a good tip, it is much easier to fit the cover to the engine now. Also I have welded on a couple of posts to the sides for pipe supports. Nick It certainly does!! What are we looking at here? David Well it stands out now! Nick

Ditto Chris!
What has come to mind and may not be quite such a nightmare to do, and get approved, is a landrover defender style rag top 1800 Ute. Would also look a little better being 2 door and already has some of the strengthened areas required. Bit of a roll bar type of thing instead of the roof and hay it would probably look the goods if done well. You would then be able to see the sky without remortgaging the house!
