Dip stick on a 250 straight 6

IF SOMEONE CAN CONFIRM THAT A DIPSTICK FROM A 1964 230 IS THE SAME, I WILL SEND YOU ONE. I'M SURE THEY ARE THE SAME, BUT LET'S CONFIRM FIRST.

That's very nice of you mike.

I really appreciate the offer.

I hope it is.

I will have to dig out my "Chevy 6" book to verify. It seems to me that dipsticks changed when the dipstick tube location & angle changed for 1968. Another consideration is whether you have the forward sump pickup pan (used on early Chevy II / Acadian). I have to find my reference stuff first, then I can post what I find.

THE ONE I HAVE IS FROM A REAR SUMP FULLSIZE CAR. I DID NOT REALIZE THE SMALL CARS HAD DIFFERENT SUMP LOCATION.

with my 250 it was from a full size chev and i had to drill a new hole to move it to the front

dip stick.jpg The tube sticking out of the 6cyl 4dr car I just got is 7 1/4 long from block to top of tube, dipstick is 14 3/4 to the top seal and 17 1/2 overall. It's also at the back of the block on right side. Dont know if thats stock?

confuse THESE SEEM TO BE ALL OVER THE PLACE. I THOUGHT IT WOULD BE A FAIRLY GENERIC PART.

TONY, CAN YOU POST A PICTURE OF THE PASSENGER SIDE OF YOUR ENGINE AND MEASURE THE LENGTH OF THE TUBE GOING INTO THE BLOCK?

HERE IS THE ONE I HAVE, MIDDLE OF THE BLOCK.

The length of the tube to the block is 5 inches

So to summarize, early (1962-1967) Acadian 6 cylinder engines are like early Acadian V8's, with a front sump so the dipstick tube has to be at the front of the engine for the dipstick to read accurately. Leftys pictures would confirm this.
Early V8 Acadians had the dipstick tube in the oil pan, rather than the block.
Thanks

I WILL CHECK MINE OVER THE WEEKEND AND SEE IF IT MIGHT WORK FOR YOU.

There were 3 different positions on these engines.

Front sump cars(nova) had them at the front near the fuel pump, like the one on Leftys car

Fullsize X frame cars were centrally located.

Trucks, Chevelles and post 1965 fullsize all had them further back near the starter braket.

Tony, yours has been drilled out by someone, and put in the wrong place, it should look more like Leftys

I thought i had even seen them futher forward closer to the distributor, but i may be wrong on that 4th postion.

All the engine blocks will fit in all the cars and trucks, just the oil pan sump and oil pick up tubes are different. so the stick will not go down to the lowest postion.

If you are just trying to set the adjustment, then drain the oil, fill it with 4 1/2 L and then make a new mark on the stick.

I did that with my winter car for engine # 1 and it lasted for years.
