I like to move the oil filter on most cars I build because it makes oil changes easier and a lot less messy. I am surprised at the lack of options for Oldsmobile. As this is my first Olds build, I had a look around the internet to see what was available. Seems like Olds. owners are stuck with the adapter that spins onto the original oil filter block. In my opinion that is a bit clumsy. So whipped up this adapter that takes up a lot less real estate behind the header. Back in the day, if the fine folks at Oldsmobile had thought to leave me enough material on the block I could have just tapped the 1\2" pipe threads straight into the block. But they probably weren't thinking about what my needs would be almost 50 years later. Anyway, I anodized the part gold which blends in fairly well with the block when everything is assembled.

 

Nice piece looks professional

 

Great idea, and great execution!

 

Thank you. Or as my Dad likes to say, "It looks store bought".

 

Well done! It might be worthwhile to churn out a few more and make available. Someone pops up looking for one every few months.


You can tap to 1/2" NPT right in the block without any problems - that's what I did. Obviously the block needs to be bare so you can clean it up.

Milan over at ROP (realoldspower.com) has a secret sauce oil system modification plan that includes enlarging the oil filter adapter feed and return, the vertical connector and the passenger side gallery.
The spin on adapters have a few nagging issues:
Induces several 90deg turns
The bypass is still in the adapter
Most of them have tiny channels

That's good to know. It looked a little thin on one corner so I didn't make the attempt. I was concerned with getting a pipe fitting tight enough without cracking a corner out or something. Do you happen to have a picture of your tapped holes?

 

You don't want to see the hack job I did.
Late night + frustration + hand drill = "good enough"

Use normal aluminum fittings with thread seal dope and won't have any issues.

 

Dayum. That's badass. You should probably turn 20 of 'em and see what happens. Cut them loose on eBay. You could probably double your money...
