Reply To: Oil bypass routing

#427339

Thank you Bob and Don,

Here are the 2 relief valves I have.  The top is supposedly ’33 and the bottom is ’35 and has a small fitting out of the top right angle elbow.

 

Based on the picture of Larry’s car. This valve is directly under the oil filter but has only one opening. The 2 I have have 2 outlets and a sliding cap and sleeve internally which I think bypasses the oil if there is too much pressure to the filter (clogged?)

There are 2 part numbers and there appears to be a break at engine 235121.
