2.8 Oil Filter Adapter Bolt

[pirate]

I have a 3.4 Crate Engine that did not come with an oil filter adapter. This engine was purchased to be installed in a small sports car so I don't have a core engine to get parts off. I was able to buy a new housing and assumed the bolt and gaskets would come with it. Wrong assumtion!

I think the part number is 12537215 but I am not sure that is correct. From the local GM dealership parts department I have been told GM no longer has it availible and there doesn't seem to be any aftermarket suppliers. I thought I might be able to get one from a salvage yard last saturday only to find out that you have to remove an engine mount to get the bolt out. Not an easy task in a junk yard at least where I was at.

Anyone know where I might get one? Anyone have an extra I could buy? Any ideas? Can't install engine (Motor Mount Clearance Problem) until I can find the adapter bolt. Thanks in advance!

I got one out of a 95-97 Grand Am with the 3100 at the wreckers, took less that 2 minutes to get the housing and Bolts.
Then use a universal seal kit for the oring and gasket.

The older adapter is different then the ones used on a 3x00. I do not believe the new one will work, however you should be able to use one from any 2.8/3.1 equipped vehicle.

The newer Oil Filter Adapters are not the same. The unit I need is the same as off a S-10 pickup which the oilfilter is horizonal to the ground and side of the engine block. On the pickups there is a single bolt that goes through the center of the oil filter adapter and a pin that locates the position and keeps the adapter from rotating. In the S-10 pickup the drivers side engine mount will not allow the bolt to be backed out and removed without first removing the engine mount. I have been told the mid/late 80's Camaro uses the same bolt and adapter but is accessable without removing the engine mounts. I guess it means another trip to the salvage yard. Thanks for your input!

The newer ones are different.
However the one of the 95 Grand Am 3100 did fit on my 3500.
I needed it in order to have the J Body AC lines fit.
Why do you need it? The one of am thinking of makes the filter sit 90* from the ground.

The car will have very limited ground clearance, a little bit over 4 inches. The oil pan is already a source for concern. With the S-10 oil filter adapter it keeps the filter horizonal to the ground an out of the way. The drawback is the filter can't be filled with oil during oil changes. I may have found what I need on e-bay and am waiting for a picture. Thanks

I have some here. PM me and let me know if you want it.

FYI, the adapter on the 3.4 also houses the filter bypass valve. Without the adapter, you'll have 0 oil pressure.

Thanks all who added comments. I was able to get the oil filter adapter bolt needed ata salvage yard from a 1989 Firebird. It is exactly the same bolt and oil filter housing as used on the 2.8 V6 Chevy S-10 pickup except it was not hidden behind and within the drivers side engine mount. While at the salvage yard I was also able to get a behousing dust/dirt shield which GM no longer produces. good trip even though it was extremely hot outside!
