No I am not talking about you lot ;D
Anybody else have what I think is one of the later dipsticks that look like they are made from a piece of thin welding rod and even a new rubber seal slides on the stick and does not seal well into the engine crankcase so you get a nice oil leak out onto the exhaust.
So had a little think then slid a piece of fine screen washer tube over the dipstick then repaced the rubber seal which is now a good fit on the stick and seals the access hole also :)

A while back I had mine being blown-out, might have been while trying to break the into and out of tesco speed record.
Mick suggested something that worked well and is still working well now, you simply wind some tape round the rod where the rubber bit seats and then shove it back, the tape making the rubber bit obviously alot wider, same principal I guess.
Another good one is the spring onto the oil cap so it doesnt come-off.
I'm thinking of wire-locking alot of the bolts, key ones like on the exhaust, carb and perhaps sump :$
While you playing there it would be a good time.
Seems to be a bit of a lost art is wire locking

Would you not just buy a new rubber bit out of Germany or Slovakia ? They are so cheap.

Because it doesnt solve the problem as seen by the 5 or so I have in my shed :$

A year or so back, I got a tube of selley's black rubber silicone cement and after cleaning the dipstick seal thoroughly i smeared a layer about 2mm or so thick all over it, then put some cling wrap around it. After waiting a few hours I shoved it down in the hole to mould it to the correct shape! :)
I let it set properly and presto, my stick no longer flew out! :D (Takes 12 hours, so you'll need to take the bus for a day)

I was actually replying to Rusty's Uncle. You seem to have hijacked the thread with your own problem ? I would suggest that your engine's breather is blocked or perhaps you have excessive blow-by ?

I know this seems like a bit of a lame topic but it is quite important as even an engine in good condition will have a degree of pressure in the crankcase and a badly fitting dipstick can blow out and at the least cause an oily mess and at worst, on a long run , run the car out of oil. :o
My theory is that the new seals you can buy are made to the original pattern. Original dipsticks were made from 4mms rod and the later ones 3mms rod so the seal does not fit the rod properly and slides on the rod then to make matters worse the seal is not expanded by the rod so you do not get a push fit of the seal into the crankcase.
So there are easy fixes to what is a minor problem and bye the way I've been given my orders by 'er-in-doors and it looks like I am going to be having a couple of Lion Reds down in their natural habitat next year :D

Hijacked? :-X
Seems like the same issue to me, from my experience with 126's I agree with Rusty, you'll always get a bit of backpressure.
Yes my engine is a bit worn now as she's gone over 55000 miles but still strong as a ox and only really blows back at over 65mph ;D

Question. Does a bis dipstick fit an air cool 126 ? In that case I got a spare dipstick if you need it. My email is [email protected]

I put a cable tie round mine and it don't blow out now!

Consider your knuckles rapped... How dare you! ;D

put a cork in it!!!! ;)

I found the seal on mine to be alright (still softish) and it doesn't let out any oil but i wanted to buy a new seal just in case and could only buy it locally complete. The seal on the brand new one is rock hard so i don't how that would seal anything (haven't tried it out yet)...
