Water pump gasket, use high-temp RTV. all others, use oil resistant RTV. I don't recommend using any on the valve cover since it will destroy the gasket if you take it off.

Randy,

For thetiming case covers and the oil pan, the factory shop manual specifies Atmosit or Curil K2. I used the Curil K2 on both sides of the gaskets and it has sealed well and stayed pliable for years. It's messy to apply, but easy to clean up. Curil T is rated for higher temperature (250 degrees C.) and comes in a 75ml tube, while Curil K2 comes in a 125ml plastic bottle with an applicator.

There's still plenty left in my 125ml bottle, so if I were doing it again, I think I'd go with the Curil T for the higher temp rating, lower cost, and it's probably a little easier to apply.

I agree with Trevor about not using anything on the valve cover gasket. As long as you replace it regularly and it keeps it's resiliency, it shouldn't leak.

I use Indian Head Gasket Shellac. Permatex makes one too, also called gasket shellac. I won't use silicone at all.

The water pump needs gasket sealer?
It came with the gasket...

It Appears Permatex Form a Gasket 2 is like Curil K2 in some areas not in others,, Permatex 2-"The product retains effective properties in contact with water , ethylene glycol,gasoline,motor oil,transmission fluid and sea water."
-54 to 204C (-65 to 400F).

Randy,

So, what's your conclusion?

Ordered Curil T($18-total-Autohaus), going to give Plastic Polyurethane formulation gasket sealer a try, I like that it remains flexible and there is no rush in joining parts together. Thanks for your input.

I use Toyota RTV on my 02 M10s, can't remember their pn but I have a tube at home. Will post it later

[bmac320i]

I use PAM for the valve cover gasket. That nonstick spray for frying pans. never had one leak or stick.

Nice

I have a weird blue squishy pan gasket on mine that did not appear to need any sealer, maybe just a little tacky stuff to hold it from shifting or squishing out.

I never put anything on the VC gasket except for oil film and it's never leaked after being reused about a dozen times. It's thick with metal reinforcement and some graphite type of surfaces on it.

A little permatex RTV in the crevices where crankcase housings meet the engine block.

Indian head shellac on coolant gaskets, bolts and pipe ends.
Indian head shellac on distributor housing because home made oil paper gasket. lol

That's all I can remember, I've not done a complete refresh.

[gsumzzz]

indian head on timing cover. zero on vc. oil pan a little carbon based grease on both sides except for 4 small dots of super glue to keep gasket from moving during install. make sure to hit the block's rear corners by the main seal, as ep said, with an rtv or permatex product. zero leaks so far after 2 years.

[320iAman]

Interesting,, I have used Permatex ultra black on the timing covers and oil pan and all is well, then it seems to develop small oil leaks,,The BMW Service Manual does call for Atmosit or Curil K2, Curil T appears to be an upgrade to Curil K2 so I'm going give it a try- non silicone formulation Curil K2 and T.

True put extra on back of engine block where rear oil seal holder joins the bottom sealing face of the block, also extra goes into where timing chain cover joins to the front of the block and the oil pan,,further a little extra where the head gasket protrudes, I clean the sealing faces with acetone and alcohol.

Like EP said its a gasket refresh , also 3-good threads on the bottom of the timing cover case and one on top timing cover..Silicone sealers don't seem to keep my oil pan and timing chain case covers bone dry, Curil T is on deck next,,

Update on Curil T , I have had Curil T on the timing cover gaskets and oil pan gasket for some time, it keeps the leaks away-contrary to rtv, I'm doing a water pump and gasket refresh and will use Curil T on the paper gasket, I like that it cures in 5 to 10 minutes, thus can tightened up the bolts very fast, going use Lubro Moly LM 508 antisieze to chase away rust formation on the securing bolts threads and thread locker blue on the M6 x 1.0 tpmm bolts that secure the cooling fan thru the engine fan pulley to the water pump.

Curil T is non messy, smells like bubble gum +1,never hardens,light green color,Cures super fast, leaves gasket separation in the express lane and has many applications. FYI Hylomar U Blue is along the same lines.

I use acetone or tone to degrease, demoistureize the sealing surfaces, dries almost instantly. Ordered another Tube of Curil T - $15/free ship from e bay my stock is getting low.

I also use indian head gasket shellac. I put it on my waterpump gasket recently.

[320iAman]

I Like Curil T- Zero Cleanup, wipe with solvent and your done, gaskets can be reused,never hardens, pull a part is easy , good to 250 C / 482 F. Its what high end shops use.

I use victor reinz just about anywhere it was intended for use.

[dreiermann]

Is any sealant used on the intake manifold gaskets (and here, I am specifically talking about the multi-piece intakes on the pre-facelift manifolds)? The gaskets I removed seemed to have a small amount of sealant (green) on one side, that may have been just for ease of assembly.

[320iAman]

Yes, intake manifolds need a sealer, Curil T is a good choice-coat both sides of the gaskets-one coolant also. You dont want an air leak there it will throw off Air/Fuel mixture. Green--Curil T Color, Blue - Universal Blue Hylomar. The gaskets that may not need a sealant is valve cover and water pump gasket, although I just replaced a water pump and used Curil T on the water pump gasket--no more scraping the gasket off there.

Viktor Reinz has a non hardening sealer as well.

I've always struggled with oil pan and timing chain cover leaks on other cars. A mechanic friend of mine then turned me on to Permatex Right Stuff. Never going back to blue/red/orange style RTV again.

This stuff always works, and I never have leaks anymore. I also really like Moto Seal, it's a very similar product, although maybe dries a bit firmer.

For intake, head and MLS style exhaust gaskets I use Copper Spray gasket.

[320iAman]

Exhaust side gaskets-I use Ultra Copper-Temperature Range "(°F):-75 - 700, "OEM specified. Highest operating temperatures for 4-cylinder, turbocharged or high-performance engines. Sensor-safe, low odor, noncorrosive. Superior adhesion. Three times more oil resistant than conventional silicones and 8 times more flexible than cut gaskets."

Are you talking about between the upper and lower halves of the intake manifold? I'm working on a Mercedes C320 that just needed the upper manifold replaced. I have Curil-T, Permatex Right Stuff Black and Permatex Optimum Max Torque/High Temp Grey. Can't decide which to use to make a gasket to solve a vacuum leak causing a lean code. Is Curil-T better for areas that have contact with gas? Any advice would be greatly appreciated.
Thanks,
Yancey

[320iAman]

Any Gasket on the intake system Curil T works well,, I used Curil T on the timing covers and its been years with no leaks. Curil T is used without gaskets typically, from my experience and others its works with gaskets as well. Maximum sealing gap 0.1 mm---metal to metal, Curil T is resistant to oil,grease,fuel,coolant,cold and hot water,salt water,weak acids and bases, ect

Curil T can seal out air as well, if I was in a code throwing issue with a vacuum leak, I'd look into additional Elring sealing compounds,, like Elring AFD 2000(Green)--immediate sealing to 5 bar pressures..
Stick with Elring your MB never had it so good.. Bye Bye Vacuum leak . Hylomar has merit as well....
