Does anyone know the part number or link for the 2009 M45 oil cooler gasket? I've searched the forum and keep finding the m35 gasket part number but its not compatible with the m45.

The m45 does not have an oil cooler.

I suppose you're looking for one to address a leak? If so, could you please post a picture of your trouble area?

Yes, I have a leak somewhere near the oil filter. Its so slow that I can find it. When I change the oil I see oil around the area. I have wiped it down and refill with oil but after an hour I still haven't seen where the leak is coming from.

The only thing I can think of is another crack in the oil pan from when I cracked it the first time. I will try and examine it more closely tomorrow.

I still can not find the source of the leak. I am going to clean the whole engine top and bottom. Then I think the best route to go would be with a UV dye. Hopefully, that will expose the leak and any others I might have.

Yeah, the UV dye seems like a solid way to go.

Have you checked the mating surface of the oil filter? By design this isn't very likely on our engines, but sometimes an o-ring could get stuck and results in a leak when you double-seal it... or a deep groove on that surface.

The dye kit should expose all kinds of leaks though.

Very right. It's used on the VQs and not the VK that the M45 is.

Thanks for the info. I took my time and cleaned it really well. Will be able to see the dye tomorrow. But unfortunately while cleaning the top of the engine, one of the hoses broke off. Most of the small hoses are very brittle and easy to crack I noticed. I will try and find the replacement hoses tonight.

Can anyone identify this part for me? I don't think I can just replace the hose on it. (It's located on rear driver side of engine and the hose goes to the back.)

It is the power valve actuator, that diaphragm is what enables your variable length intake manifold. I'd say most owners don't even notice when that hose deteriorates. When it is working correctly, it will be a slight effect comparable to VTEC kickin' in yo!
The hose is removable and replaceable. But it is not the most convenient place and the rubber will most probably be caked onto the nipple. Get a light, mirror, video camera, scope etc... otherwise, you will most probably be seeing with your hands.

If you're interested in seeing what it does to the intake, look at minute 3:00 of the following video:
