1966 250 dipstick correct?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Matt58 · 12-09-2015, 08:01 PM

I have a 66 c10 with the original 250 six cylinder and according to the dipstick it holds 4 quarts of oil up to the full mark. I read it is supposed to hold 5 quarts. I am using the larger filter...Does this appear to be the original dipstick? or any other suggestion?

My 70 with a 250 6 was 5 quarts with filter,4 without filter. I can't double check since I don't have the truck, but that does look like the dip stick for the GM 6.

I am showing full with a new wix 51060 and 4 quarts of oil. Could I have a quart of sludge in the pan?

My 292 also takes 5 quarts with a filter.

**Palf70Step** · 12-09-2015, 09:49 PM

Have you run it yet?

Matt58 · 12-09-2015, 11:12 PM

Yes have run it... seems ok but want to have the correct amount of oil..

A) make sure the dip stick tube in the block is correct
B) do you have a friend that has a 250 ? borrow his dip stick and see if their is a difference.

Just from what I can see , that dipstick looks to be the pre 1963 design with the , for lack of a better term, the loose washer style , they used these on early 235s and v8s. Then they changed to the style with the sleeve that fits over the dipstick tube. Is there a part number stamped in the dipstick down at the bottom ? Looks to be something there? I can track that number. I would put the 5th quart in it and mark the level after its been run. Never heard of a 4 quart system.

Since it was mentioned, I looked in my old photos and this is the only views of the dipstick on my 70's 250 that I had.

Maybe they will help, but it may be as said above that was one from the older style 6.

Thanks for your help guys. It has no numbers on it but has a M stamped close to the word FULL. I have a friend with a 250, will see what his has. Thanks again.
