6.5 Oil Sending Unit Replacement?

[chestatee]

The 97 OSU is located under the intake at rear as many may know. It has a slight angle that is preventing me from getting the special socket on, which I always used for earlier models. Is there a new removal tool for this setup or do you have to remove the intake?
Thanks

I use a 1 1/6" deep socket. Sounds like you need a basin wrench?

Is there something on the intake making you "angle" in to it, or are you saying your ops is at an angle?

 

[chestatee]

When opu is installed it angles toward valve cover which makes it hit intake.

Wobble/flex extension?

I could be wrong, but iirc it should be vertical. has it been damaged maybe-bent at the threads? If so its trashed anyways and I would try bending it back. Can you put up a picture?

I wonder if someone put a street ell on it? Should be pointing straight up.
BTW I sell an OPS extension hose on my site that would make this a 5 minute job.

If you just want to replace it, I would butcher/break the plastic portion and it will be easier to take out.

Then you can buy what Leroy has to install a new one back.

I haven't made it back to the shop, but the 97 has a fpt tapped near the bottom of the block valley to the left of fuel manager at near the same angle as the valley. The opu goes directly in with no brass fitting like earlier models that were behind the head with a brass fitting to mount opu. I assume GM engineers thought this was an improvement vs early model 6.5"s location, but at this point it's suspect.
Thanks, will get back with a fix and pic

Aw shoot! Didn't realize you had the van engine, I assumed (something for me to remember about that word) you had a truck engine.

Definately get an extension hose on that for next time.

I don't as noted that was 2 pics from the web. That was a good shot of ops to show angle. Thanks

Had to use a 1" crow's foot to remove, 1 1/8 wouldn't bit enough to remove.

Made up Teflon hose with brass fittings to avoid future problems with change.
Thanks for your interest

IIRC the OPS needs to be grounded
