The Stovebolt Site Forums The Shop Area Engine Shop 235 Oil Pan

I have a 1953 235 in my '46 truck that has a leaking oil pan. I have a good 1946 oil pan. I know there are differences between the engines, but does anyone know if the '46 oil pan will fit the '53 engine? I fit will, I won't bother trying to fix the leak.
Thanks

Is the 1953 235 a splash or full pressure engine?
Either way the pan with fit, but if it is a full pressure engine you will need to cut the troughs out first.

It's a babbit bearing engine.

I was hoping it was a full pressure engine.
Even though the 216 and 235 have a different stroke Chevrolet sold a replacement pan to fit both engine. You were instructed to set the troughs in the pan to match the stroke of the engine you were installing it on.
It may be easier for you to fix the leaky pan in this case.

Pre '68 Dave:
Do you have further info on setting the oil pan troughs to match strokes on that "replacement oil pan" ?

Checking the height of the troughs and the alignment of the spray nozzles was supposed to be done anytime a pan was removed. GM dealer shops had checking fixtures for both procedures, but a simple test using a piece of angle iron and a combination square will accomplish the same thing. Alignment of the oil spray can be checked with a garden hose plumbed to the oil pan and an "X" scribed on the side of the pan directly opposite each spray nozzle.

As far as trough height, I do not have the dimensions, Chev had pre-made gauges for that setting. I do not know if they ever gave actual dimensions.
One could compare pans to check height.

As far as what Jerry is speaking to, that is nozzle alignment. That can be checked with a garden hose. Under medium pressure the jet of water should hit in the center of the approximately 3/4" x 3/4" square stamping opposite the nozzles.

There were two factory tools:

216: J-969-2

235: J-1646

I only have dimensions for one of them, and I'm not sure which it is. The diagram I have in an old Motor manual lists the dipper height from the oil pan rail with the rod at the bottom of the stroke at 3 29/32". The same tool measures the trough depth at 3 5/8". The 235 will have a longer dimension than the 216 for both measurements because of the longer stroke.
