glycerin? Carbaflo?-VCG

I'm doing my valve cover gasket this week and I'm stump of what product to coat my gaskets?:dunno:

I didn't use anything on mine. The idea of the glycerin is just to make them slippery so they will go into the groves of the valve covers easier. But I had no problem putting them on dry. Just make sure the valve cover sealing surfaces and grooves are clean.

PS: You still need to put RTV at the half moon shapes at the back of the head and where the timing cover meets the valve cover. Don't confuse the RTV with the glycerin. I hope I didn't cofuse you more.

Thanks:thumbup:, I defiantly got the RTV down, I just got confuse about the Glycerin, since this product is sold in a drug store and not in an auto part store. I been reading all the DIY ride ups, and they used this product. I also read that BMW discontinued Gummi Pfledge(Glycerin), and went with Carbaflo, their must be a reason for that:dunno.

I think I found were to buy Glycerin I just don't want to have any issues. If I don't find Glycerin what other options are there?

I think you can still get glycerin at the drug store, but I haven't looked for that stuff in ages, so don't quote me on it. But, I have heard that people have used Neutrogena facial soap (the bar, not the liquid) which has a high concentration of glycerin and they said it worked great. Just mix it with some water to build a lather and run the gaskets through your hands to coat them. (And before you ask, no, I'm not joking:rofl:)

I will second that. I just did mine about 3 weeks ago and did not have any need to use anything. The gasket goes in very easily.

I searched 2 chain drug stores and a large supermarket. CVS, Rite Aid and Pathmark. Not had them. In the end, I bought a bottle off Ebay for a few bucks.

One seller

Although that is not the seller I bought from. Glycerin is Glycerin. It's a derivative of vegetable oils. Used in cake icing, soaps, moisturizers, personal lubricants-just to name a few.

you put NOTHING on the gasket, just make sure gasket and head surfaces are clean and free of oil. use permatex #2 for the half moon, and the front spots.

Carba flo and glycerin are used on the door gaskets, have not heard of it used anywhere else on an E39.

at the shop we use victor reinz products. they make a black silicone gasket maker that we use on the half moon shapes of the gasket. no other lubricant is needed. the gasket will fit in the grooves once you tighten the bolts on the cover.

I came to this old thread trying to help 540Indiana out with his upcoming V8 VCG DIY:
- E39 (1997 - 2003) > Doing VCG tomorrow

But, I'm curious about organic chemicals ... so ...

Am I correct in inferring that this thread intimates BMW used to sell something called Gummi Pfledge to lubricate the VCG, and now they sell Carbaflo, both of which are primarily glycerin?

I just bought a 4 ounce bottle of glycerin at the pharmacy section of a local Target department store.

Note: I was really looking for glycerol or a glycol for the smoke machine I am making - but the point is that you can get glycerin at a pharmacy if you need it for the VCG.

For the crosslinked record, since this is the canonical thread on the VCG gasket RTV, this was posted today:

(1) I've seem many articles on valve cover replacement. They all mention RTV sealant, but when I research RTV I see many types. The only one I saw mentioned was Ultra Copper (sensor safe), which I happen to have an unopened tube of, but it's "gasket maker" not a sealant. Looking for opinions....

(2) So, until my vanos seals (Beisan) and some warmer weather arrive, I'd like to temporarily seal my leaky head gasket. It's right at the front over the vanos. What sealant could I mush into there as a short term repair that would clean up easily later on? I was thinking maybe a general purpose clear high temp silicone. Do I have to worry about sensor safe in that area? I'm trying to avoid doing two valve cover gasket jobs. I'd wait but it's spilling oil all over my lower rad hose and I'm sure that's going to weaken it.

Thanks -Bob
