Valley pan replacement using sealant

[senorcarey]

While trolling through YouTube videos tonight, I found a gentleman who claims that he doesn't buy new valley pans, only reseals them with black RTV.

Since everything is true on the interwebz, of course, is there any wisdom in this?

use this gasket

11141736175

remember to peel the old "bead" of silicone or whatever is on the old valley pan and clean it with some scotch brite or something before installing

Thanks for the info, but I can't seem to cross-reference that part number anywhere, including RealOEM and AutohausAZ. Is that correct?

Garey used RTV on his I think, due to his experience with the poor factory gasket design. Maybe PM him?

The "right stuff" seals just about everything extremely well. Just make sure you don't need to remove it again because I did my oil pan on another car with that stuff and it took me about an hour or more to separate the pan from the block....and this was on an engine stand.

I'm an idiot and typed the wrong number... 11141736175 $18.80

What exactly is that gasket? I got a new valley pan, and it had a rubber-like bead of sealant already applied to it, I just bolted that right to the block...

Thanks for the replies. I've seen that gasket before, but depending on what subsection you look, it lists the part as the entire valley pan. I'll look into it at the local dealer for giggles (price is usually ridiculous here).

I wasn't going to get into the pan, as it wasnt leaking, but I'm this far in so it only makes sense. I like the sealant idea as its easy.

Once again, thanks for the replies and any additional info is welcome!

Good info here. I will have to do this soon (3 times) and buying new pans just seems silly for the little rubber beads.

IIRC you were able to order 11141736175 by itself before, but lately you get to order the complete metal pan with the gasket bead attached?

Last 2 valley pans I've done I was not able to get just the gasket.

[senorcarey]

According to Camelback BMW (local), the part is available, but will need to be ordered. He can have it in 1-3 days. The price quoted was $22.xx.

I did use RTV on mine as a "trial run" since I have about 6 old valley pans lying around... guess what... it leaked. I think if you gob on enough RTV (I didn't want gobs of RTV pressed out from below the pan, which would look half-baked) it would probably seal, but given the headache it is to get to the damn thing, use the gasket or buy a new pan. It looks as if BMW made an "update" to the pan/gasket setup at some point in the mid 90's and started to vulcanize the silcone gasket to the valley pan, so the individual gasket was no longer needed.

If anyone has done the coolant tube o-ring replacement on an N62 V8, you'd appreciate how shady a vulcanized gasket/seal can be, which is why I dislike the vulcanized gasket deal... it fails... always...

My 2 cents anyways...

I'll reply with more later, but I'm getting the impression there are at least two different styles of pans. Perhaps one lends itself to resealing more so than the other?

FWIW, I bought what was supposedly the updated design of the valley pan gasket and it's leaking less than 3 years later. I can't for certain say that I did it right, but believe I tightened it correctly. It came with the gasket affixed to the metal inlay, and on the one I removed, it was the seal that broke away from the metal pan, instead of the seal with the engine block. [I haven't replaced the current one yet, so don't know how it went wrong]



I'm not sure how you are supposed to attach or seal the new gasket to the metal pan if you buy the gasket separately, or how long it'd last if you did. I might put a ring around the outside of the gasket to add a second seal between the pan and the block next time.

^^^ That's to the point I was making about the vulcanized silicone... they fail. I don't think there is more than 1 type of pan, just the vulcanized seal or not. I would use the gasket in the future and be done with it, rather than trying to band-aid the vulcanized pan with an additional bead of sealant... just remove the bad silicone entirely and buy the gasket... done and done...
