I PULLED MY FIRST OIL COOLER 1996 7.3. AS I REMOVED THE COOLER LOOKS TO BE A CHECK VALVE TO KEEP OIL FROM DRAINING BACK INTO THE PAN FELL OUT WENT INTO 3 PICES . WENT ON THE WEB AND DEALER TO FIND A PIC TO PUT THIS PART BACK TOGETHER IN THE RIGHT WAY AT A DEAD END. THANKS MUCH

 

bip,
Welcome to FTE and the IDI diesel forum.

Did you miss type the year?

If you are working on a 96 I can move this post up to the 1994.5 thru 1997 Power Stroke forum.

We do 94 and older IDI engines here.
