Can some kind soul who has a Crossflow 711M engine take some measurements of the dipstick for me. There is a metal collar crimped to the Flexi-rod, which is located approx 2/3's of the way down. Unfortunately mine has come "un-crimped" and is now sliding up and down. This is a major problem in ensuring the correct oil level is achieved as the collar is how the the dipsticks seats itself and therefore dictates the height of the 'min' & 'max' lines. Probably the best measurement would be in mm from the bottom of the dipstick tip to the lowest part of the collar.

The flat end in the oil is marked as P/N '711M 6750 BA' - any different P/N may have the collar set at a different height, so it needs to be a similar item.

Also if you could measure the full length of the rubber tube that holds the dipstick, that would also be very helpful.

Thanks guys

Hi

Just been out to the garage to check on the Vixen's dipstick for you. It's marked 711M 6750 CA.

21.5 cm from tip to bottom of the crimp stop.

28cm for the length of the rubber tube the dipstick pushes into from where it enters the block.

I'll post a photo if I can work out how to reduce the file size to the max 2mb

All the best

Marc

the dipstick length does help somehow but finally not:

the rubberhose in the block must have the correct length, otherwise the readings on any dipstick are wrong.

why i say this? the rubberhose might have been replaced (by a wrong length or a wrong type) or due to a crack in the rubber, been shortend

I had already shortened the old rubber hose because it had split at the base. However it did not alter the dipstick readings, just the top of the dipstick protruded from the top of the rubber hose by the same amount.

The downside was that during the cold weather (winter) moisture accessed the top of the tube as the dipstick was too long and left a gap for moisture to enter. This resulted in 'mayo' deposits in the rubber hose and on the dipstick.

It may have also contributed to the crimped metal collar coming loose as the dipstick, not being seated on the top of the rubber hose because it was cut short, put all it's weight onto the collar.

Anyway, I now have a new rubber hose (correct length) and the collar recrimped at the correct point. Fingers crossed, my thinking is all correct and this is sorted.
