There's a word of CAUTION offered in the answer to this trivia question:

What is unique about the early CIH aluminum oil pan with the dipstick on the passenger's side?

First, the pan's capacity is 3 quarts without filter, but that's not what's unique. The space between this pan's dipstick marks measures 1.5 quarts . . . HALF the pan's total capacity and unlike all the other dipsticks' one quart measurement.

Pans and dipsticks . . .

Otto,
My '70 Kadett has the dipstick on the passenger side, w/1.9L. Does that mean it also has the aluminum oil pan, or is it only the dipstick that would be unique?

AFAIK, all CIH engines with the dipstick on the passenger side share this type early aluminum pan and use the same unique 1.5 quart "between the marks" dipstick. Don't believe the CIH engines ever had a steel pan with a passenger side dipstick. Matter of fact, I believe all CIH steel pans used an "in-block", driver-side dipstick. The "driver-side dipstick" aluminum pan had an extra boss cast in it for a steel dipstick tube, and had the in-block hole plugged with an aluminum plug.

To confuse things even more, all these pans use different type and length dipsticks. The in-block dipstick also requires an in-pan tube to guide dipstick around the crank counter weights. Thoroughly confused now?

does this mean you can't get a steel oil pan with the dipstick attached to the pan, not the block? because... mine doesn't go through the block, just wondering if there is something else that's weird about my car

If dipstick is on driver's side and doesn't go in the block, it's probably an aluminum pan with the dipstick tube mounted in cast-in boss.

Alu oil pans

Jared, isn't yours a 72? My 74 Rallye came with a steel pan and I have 2 of 6 engines/transmissions that came out of other 74s, that have the steel pan. One is like Ottos first post, the others are like post nos. 4. Jarrell

True. Alu pans with steel dipstick tube on driver's side was later version used on Rallyes and had fins toward front of pan, early pan with hole for dipstick on passenger's side had no fins, smooth as a baby's behind.
