Holden GenIII Oil Surge - Dipstick Fix

When Holden adapted the Corvette motor to fit in the Commodore, one problem they had was clearing the crossmember. This required re-designing the sump. To make it clear, the bump in the sump was moved to the front of the engine and the oil pickup relocated forward. This has the downside that under heavy acceleration, the oil moves to the back of the sump and reduces coverage of the pickup.

Holden changed the length of the dipsticks in later models. Here is my VT Series II dipsick measured against a friend's VY Series I dipstick.

And a close up of the business end. As you can see, it is basically 1cm shorter.

To save you having to read from the photo, the key lenghts of the VY dipstick (shorter and cleaner) are :
cm Length from yellow lip in cm
56 Start of wavey bit
55.5 End of wavey bit
56 Start of Good range ie. Full
57.4 End of Good range ie. oops
61 End of dipstick
