L series engine oil dipsticks

OK, now this is getting interesting jerz. The engine the P6500 dipstick came out of is an L-28 with F54 block and dished pistons. It had been freshly re-built by a well known local engine builder. When I got  the engine it had a P79 head, leading me to believe it did in fact  come out of a 280ZX. If that's true, then your information on the P6500 dipstick is probably correct. I measured the  dipstick tubes on both my engines. The one on the L-24 is exactly 3" long. The one on the L-28 is 3 1/8." The difference in the two dipsticks, to show full, is 1/4." At this point, I'll be swapping the L-24 dipstick out, and the L-28 one back in. Tomorrow I will carefully measure how much oil it takes to raise the oil level in the engine by 1/4" on the P6500 dipstick to determine how much difference it might make running an incorrect dipstick. I'll let you know what I learn.

How about a difference in the receiver tube length that is mounted in the block? Might this account for the apparent different dip stick lengths?

i can hardly wait to get home and peruse my dip stick collection. Why I have a dipstick collection is another question with no answer. ..

 

That's the most likely answer. My E-Fast is down right now so there are a couple of things I can't check right now. 

Edit: Ok. So I just did a side by side comparison of the E3002 Dipstick ( Z ) and the P6502 dipstick ( ZX )

I measured from the rubber shoulder seat to the high mark on each dipstick. The high matk is what you should be comparing. NOT the overall length. The E3002 measures 7.375 "  to the high mark. The P6502 measures 7.00 " to the high mark. What that means overall.... not a hell of a lot IMHO.

F54 block on my car, so P6502 is definately correct

 Also considering that I ordered a new 11140-E3002 dipstick, and it was superseded to a 11140-P6502 ( This is in Canada ) .

Ok Guys I have a 77 Skyline kenmeri with 280ZX F54 block but we used the original oil pan from the L24 engine  to make the engine fit on the cross member. I am missing the dipstick for the L24 oil pan. Can somebody help me get a dipstick or a part # for that 77 Skyline 240K GT L24 engine?

Thank You guys in advance.
