The fluted bit is at the base of the filler neck where the boss is which bolts to the case, not the dipstick tube side
Not all type 4 engines have one (shock horror). Some have the bendy tube in the breather stack ie differnet dipstick arrangement! I used to run type 4 from a T25 which I converted using bay engine parts and that had two dipsticks!
Why what have you got fitted? All engines that were intended to be in a bay have the same dipstick arrangement with the bellows!
My 15 are confirmed as on their way. I owe @Dicky one and need three myself, the rest are up for grabs.
Though my engine no longer leaks, think I'll have a spare. TBR can you send me one. I'll PM you my address.
I’d like one please – I’ll PM you a UK delivery address as I’ll be there in a couple of weeks. Is bank transfer for payment okay? I don’t do PayPal.
