1997 Itasca Sunrise Engine Rebuild - Lost Oil Filter Adapter

I have a 1997 Itasca Sunrise with the Chevy 454 TBI. The engine needed a rebuild so our first mechanic pulled the engine out and we sent it to the rebuilder. Now the engine is back and in the chassis.

It seems between here and there somebody has misplaced the oil filter adapter that bolts to the block. My mechanic says it would have four bolts.

The GM part number is 12562830 and GM has discontinued it. I have spent the last 3 days calling all of the country trying to track this part number down.

Would anybody have any suggestions for places to call for this part? If I cannot find one, what are my options? My mechanic suggested we might need to find a new block and move everything over to that, but I really don't want to do that :(
  • I see the problem with your part number. It's listed for a P30 chassis which would be correct, but a 5.7, not your 7.4. Let me dig some more.
  • I just called a buddy that works at a Chevy/Workforce dealer. He was not able to help. The factory cooler lines do not go into the adapter on the Vortec engines which began in 1996. What year is your chassis? PM me the VIN if you wish, I can go further with that info.
  • I think I found one that will work. PM your email or a fax # and I'll send a drawing. Part number is 12559660 listed for a 7.4 4WD pickup. It is still available thru any GM dealer at $67.29 plus any tax. Your chassis was not built with the engine oil cooling option, so I'm thinking that if they used GM stuff this would have been the one.
  • This looks very promising. The original part looks like it had leg that extended over to where the oil cooler lines go into the block. The holes look big enough to allow the oil cooler line fittings to pass through to screw into the block.

    The main body of this new part looks like the main body of the original part. I am going to call my Chevy dealer to see if I get my hands on one.

    Thanks guys!!!
