What sealant

[achillies]

Is Loctite 5900 the sealant to use when replacing the oil pan on a 2000 996? Thanks

I think what Porsche uses is equal to Loctite 5970.

Porsche says Drei Bond or Loctite. I used Permatex Copper, same basic formula. You can also get Drei Bond at the VW dealer for about 2/3's the Porsche price.

One of the most important things is not to use too much. The 1.5MM bead that the manual specs is more than enough. What you see that squishes out on the outside when you tighten the oil pan shows about how much is squishing out on the inside. On this inside this can break off and get sucked up into the intake. I have see pictures of intake in 996's almost completely blocked with pieces of sealant.

It is a common mistake to put too much sealant on, thinking the more the better, but it can lead to serious problems.

Could you post up your reference doc or source? I could not find any documentation for the install. Its not even called out in the X51 documentation.

Nice. Well there you go achillies. :) The Locktite 5900 is what Suncoast sells. No leaks.

Here are links to the specs for Loctite 5900 and the Permatex Copper that I have been using.

Loctite 5900 http://www.rshughes.com/images/products/do...RWxTnQdHZsw.pdf

Permatex Copper http://www.permatex.com/documents/tds/Automotive/81878.pdf

Both are Oxime silicone, different in color, I think the Permetex actually has a higher termp rating.

Loctite 5970 is slightly different, here is the spec for it http://www.loctite.cc/template/ying/pdf/docs/5970-EN.PDF it is Alkoxy silicone whatever that is.

My manuals show Drei Bond 1209 or Loctite 5900, no reference to Loctite 5970.
