casting help.

1981 f100 with 300 i6 auto 2wd

My motor has a casting number
of e5te-6016 or 6010 and I think MA can't find a date code. My block doesn't have any bosses for the dipstick the dipstick is coming out of the drivers side of the pan with the drain plug on the passengers side and it's a rear sump pan is this even a truck motor? Any help would be appreciated I'm trying to figure out my proper oil levels etc. Cause my dipstick is wrong. And it's obvious the block isn't original.

My trans is a c6 is I believe the valve body casting is d7th I think.

And I think I have a ford 9 inch thirdmember.

Do an oil change, leave out one quart
Start the engine and allow the filter to fill.
Take a file and make a notch for 'low'
Add the last quart and make a notch for 'full'

Was there any possible 300 i6 oil pan combos that could only hold 5 quarts?

Not sure, but I do know when I swapped in a 351w from a car, and got a rear sump oil pan from the junkyard to make it fit my truck, it would leak out of the rear main if I put 6 quarts of oil in it. If I only used 5, it was fine.

I had made my own dipstick like was mentioned above with a hacksaw blade marks. I always thought it took 5 quarts, and ran it for years like that. I then saw on here that it should have 6 quarts. So the next oil change I put 6 quarts in it, and that's when it started leaking badly out of the rear main seal of the engine. I just went back to using 5 quarts.

E5TE = 1985 F150/350, Bronco, Econoline casting number prefix, so the engine has been swapped.

All 1980/82 F100/150's have a 9" rear axle.

8.8" integral rear axle introduced in 1983, but some F100/150's, E100/150's and Bronco's thru 1986 could have the 9" or could have the 8.8" as it depended on the applications.

I figured it had to have been swapped at some point. And my transmission isn't original either. Did any of those vehicles have the dipstick in the oil pan?

I put in 6 quarts my last oil change had that horrible blow by and leaking gaskets and bubbles on my dipstick I just changed the oil again only put in 5 quarts blow by seems to have decreased alot not as much gasket seepage and no bubbles on my dipstick.

Just as a question how many quarts of trans fluid does a stock c6 hold?

Stock c6 will hold about 13 quarts if you drain the torque converter.

The 351w pan I got from the junkyard had the dipstick in the pan, which I was grateful for. The engine I used came out of a 78 cougar, and it did not have the dipstick in the side of the block, only the one up front.
