When I bought the Range Rover, the bill of sale read 2004,HSE. I purchased some valve cover gaskets, to stop an oil leak. But now I'm wondering if this engine was changed, or if the heads were changed to a later comparable year, I bought Felpro gaskets. The gasket material dips to the inside of the bolt. However on my engine, the gasket material dips to the outside of the bolt. I also only seem to be able to find one vanos. I can see the one on what I assume is bank 2 (left side of the engine, when standing in front), but I don't see a vanos on bank 1. How can I find out which engine this is, and if it was modified? (I doubt the dealer would know, it was not an official Land Rover Dealership, and I have a feeling that if he did know he wouldn't tell me...). I'm not new to auto mech, but I'm really new to this engine, so forgive me if this was a dumb post. :mrgreen:

(This is the new Felpro gasket, but where I marked in green is where the actual engine gasket material would be. I did use the smaller internal gaskets for the valve cover, and just used gasket sealant to re-seal the old exterior gaskets - the oil leak did stop, the spark plug galley was full of oil, both banks)

I've never heard of this brand. Personally, I'd only go with factory OE or Victor Reinz. Here's a link to the latter option:

Fel-pro has been making gaskets for about 60 years or so. They were about all that was available back in the 60's and 70's for aftermarket gaskets for american cars and trucks.

Funny that for years I only knew Felpro. It’s Victor Reinz that I’ve never heard of.
I suppose you’ve not heard of Moroso either.

Yea, never heard of Victor Reinz either until I joined this forum. Since Land Rovers are sold all over the world to I guess there are many sources for parts. Moroso has been in the USA since maybe the `50s.

Those gaskets from Victor Reinz still have the same pattern as the ones I bought from Fel-pro. Those aren't going to fit either, which is why I think some pieces on this engine were swapped before I purchased the truck.

This pic is from the AlldataDIY manual. See how the gasket goes in front of the bolt holes instead of behind them? That's exactly what I have. Except none of the available gaskets, except the one already on the engine, do just that. I found a set of valve covers where the gasket goes behind the bolt hole. I may just get them so I can use the new gaskets, and have peace of mind.

Your 04 should have the M62TU BMW 4.4 engine. As far as valve cover gaskets go, you can source them from bmw for cheap as well. Same engine as e38 740i, e39 540i and e53 X5 with the 4.4. Post pics of your engine. Let’s see what it looks like.

ignore the grime. It was already getting cold out when I bought her. She will look better when I can get some warm weather wrench time.

They probably just updated the design of the gaskets. Having the bolts inside the ridge of the gasket leads to oil leaks down the threads of the valve cover bolts. Keeping the bolts outside the sealing ridge prevents that. Now if theres a groove cut in the valve cover that doesn't match the new gaskets profile that would be a problem, but if the bottom lip of the valve cover is flat the ones in the picture above will seal better.

99 to 01 BMW M62TU valve cover:

The gasket is correct as shown, the drawing must be an a graphic artists rendition, or they used one from a similar engine.

But that's just it - the groove on my valve cover goes to the outside of the bolt, not the inside as shown above. I'm ordering a set of valve covers like the ones above, and I'll swap them out when I do the timing/vanos (ugh). it will be a few months because I want to wait for the warm weather before I tackle the job, but I will have some compare pics.

Thats really odd. Theres no doubt that you have a 4.4L BMW M62TU engine from the picture. When you take the covers off see if the casting number on the inside of the valve cover is 1703174, because thats what it should be for any BMW engine in a RR. The 97 to 99 BMW 4.4L engines valve covers have the gasket that go outside the bolts, those have a cast in part number of 1742130. Going to have to find the build date and VIN number stamp on the engine to see if its original somehow.
