Leaking Taco Plate

Silent Running · Posted: Sun Sep 12, 2010 8:56 pm Post subject: Leaking Taco Plate

Just wondering if anyone has had a leaking taco plate before and how you resolved it. I installed an oil temp sender and now the taco plate is leaking pretty badly around its perimeter (not at the sender). Should I get a new o-ring? Thanks for any help!

First you might torque the bolts to the ftlbs speciified in Bentley and see if that stops it if not then replace the gasket.

Easy to pinch the orange O ring around the inspection plate there ....

By all means replace the o-ring and torque the nuts. I bought a new plate with the sender fitting from Air-cooled.net, a nice looking billet piece. I thought it would be trouble leaking but not a drop. I think torquing the bolts evenly might be a key.

That is crazy- looking. I remember seeing one of those now, but I thought someone made it, I guess Phil? And that's the one that aircooled.net sells? again, I didn't see it.

A discussion of whether the fins would affect the reading. Seems to me the threads are way down that small hole. Does the sender fit down in there?

To not totally hijack, git a pic of the bottom? I used a large radius bit to cut a groove to resemble what VW has from the stamping. It is a tricky piece to make, with the type of 'gasket', the sealing lip is so small.

With a stamped stock piece, tolerances in production, it's surprising they hold so well.

Yes the sender fits down the hole in the plate tward the rear int he center of the picture.

I don't have a picutre of the bottom of the plate as it is in the bus.

I am not worried about the cooling fins.

That good O ring is also in the good complete gasket sets from Elring.

Thanks for the info everybody. Looks like I may have overtightened the bolts a bit. The good news is that the o-ring doesn't appear to be damaged. I'm going to give 'er another go at 5 foot pounds of torque and see if that resolves the issue. Update to come...

I also used the 6mm copper sealing washers (from a type 1 oil change kit) on those 2 little bolts.

Thanks Randy, do you think the copper sealing washers are critical (read - I don't have any on hand Smile

)?

The "Phil pill" is not the one I have but it looks like it would protect the sender better than mine.

Well, so far, so good. I found a place in town that sells the original replacement o-ring, so I'm going to head down and pick one up today just in case Smile

Thanks again for the help!

Thanks Ritter, that's one of the things I asked them Smile

- and yes, it is the orange one.

So, one final update. I noticed an ever so slight leak coming from the plate still, so I drained the oil again and installed the new o-ring and BAM, not a drop - whoo hoo!
