both sides of the timing cover gasket?

im also replacing the bothersome throttle body heater.. i was warned not to add anything to the gasket on that thing.

 

By both sides, I mean front and back.

I don't even have a gasket on my throttle body heater. It's just RTV.

It hasn't leaked a drop in a year so far.

RTV is a miracle product IMO. Just don't use too much.

 

x2 on a thin coat of black RTV anywhere you would normally use gasket cement.
on the throttle body heater it does hurt to run a file across the body to level it.

 

will do.. on the rtv. glad i bought a new tube of it then..

 

i bought high temp stuff. my buddy who is a LR tech at prestige, says that this is perfect..

 

Well, there are a ton of different types of RTV, so I always read all the packages to see which is most appropriate.

With a gasket that contacts oil, I believe black RTV is recommended. I'd have to consider the temps to be sure it'll hold up, but that's the first package I'd read.

 

When I ordered the parts from AB they said I didn't need any kind of RTV. But the rave manual has specific gasket sealant for each part and some king of thread lock. I read not to use silicone gasket sealant. here is what I read its Wiki answers so who knows if it's true. -- Both block and oil pan.Install new gasket. NEVER use silicone sealer on an oil pan gasket or any other composite or rubber gasket. (Most people call composite gaskets cork gaskets because they contain ome cork but pure cork gaskets have not been used for oil pan applications for more than 50 years.) Use of silicone sealer on an oil pan gasket will dramatically increase the chances for a leak and make it harder to get the proper torque on all the bolts around the pan. Let the gasket do the sealing job it was designed to do. Trust me if you do it yourself YOU WILL HAVE AN OIL LEAK! . But again the rave manual says to use a special sealant? SO should I use some kind of sealant on the gaskets Our just install them?

 

I would use RTV on the oil pan gasket. It certainly is not going to "dramatically increase" the odds of a leak or create uneven torques.

And this: "Trust me if you do it yourself YOU WILL HAVE AN OIL LEAK!" is completely ridiculous, IMO. I have proven this wrong probly 100 times in the last 20 years.

Just give it ample time to dry and you'll be glad you RTV'd it.

 

That's messed up. I'm doing this to fix a coolant leak behind the timing cover. Didn't know I might just create another. What does land rover do different to not have a leak our is it the same when they do it?

 

when land rover put your engine it was on a stand with all fresh machined surfaces on all the pieces. Now it's 10+years later and your engine has heated and cooled a few million times and those surfaces are no longer true, hence your sudden timing chain cover leak. All the parts, bolts torque figures are specified for a straight and true surface (which you no longer have), one way to give yourself an edge is to use a thin coat of RTV along with the gasket.
