Dipstick oil seal are there two seals or only one

or is the oil seal placed on top of block

or from underneath

there`s generally 2 types of dipstick,

one is the early std mini type,flat metal with a little rubber boot that slips up to the round flat section on the stick,,, & goes with the plastic type tube

the other is the "S" type, looks like it`s 2 bits of steel folded & takes a tapered type seal fitted to the stick,,, & takes the metal tube

hope that helps

edit,,, sorry there is a 3rd type, Late APlus type, & it doesn`t have a tube in the block, it is similar to the "S" type but just simply fits into the countersunk hole in the block

No offence intended here but--> anyone writing a book about minis 30 years ago may not have experienced such worn or stuffed-with components as we are finding these days.

You should put your heart & soul into everything you do.

PLUS there is the very early 850 dipstick with no tube just goes straight in the block.

ok I just want to confirm the actual tubes plastic non S or steel Cooper S

is there an Oring fitted to the metal tube as well inside the block or under the rolled lip on the outside top of block
even for the plastic tubes

I think Matt is having a senior moment.
The Plastic Dip stick tube type is definitely the Later type fitted on. Mini K.

There is no seal of any type fitted between the block and tube on either the metal or plastic type tube.
I normally Glue in the plastic type with epoxy, they all seem to become loose with age,
The Metal tube is normally a nice tight fit even after being removed and replaced a few times.
