4.7 Oil Seepage or Leak

Hi everyone

I am getting prepared to replace the timing belt on my 2006 Tundra Double Cab very soon. I was checking out the engine and I noticed some oil behind the timing covers. Would this be a possible cam seal leak or valve cover leak? The following pictures show the leak on both the drivers side, and the passengers side near the power steering pump. I wanted to make sure I have all the correct parts on hand before I tackle this job. I am a weekend mechanic, but have sucessfuly changed a timing belt on an 2004 Acura MDX. Thanks for you help with this!







When changing the timing belt, I was planning on replacing the timing belt, tensioner, pulleys, water pump, thermostat, radiator upper and lower hoses, as replace the coolant. I was also planning on changing spark plugs. Did I miss anything?

Thanks!
Nathan

Looks like a light seep.

Can't really say I would worry about it, not wet, not dripping.

Thanks Powertechn2!

Do you think I need to have the cam seals on hand when I tackle the timing belt, or do you think it is coming from the valve cover?

I have never been into a 4.7. So I can't honestly say.

But in general, the way I look at things is like this.

A. Try to have everything you might possibly need on hand.

B. Try to have everything you shouldn't need on hand.

C. Fix everything you can while you are almost all the way there as you are almost all the way there.


Only exception is crazy ladies.

There is no fixing everything, just do what you can, and deal with the rest later...


Sorry, it is a moonshine night. But other than the exception, all else is true. And even the exception, just it doesn't apply here.

Bahahaha

Thanks, I will keep that in mind. I guess I better order the cam seals, crank seals, and valve cover gaskets just in case. If anyone has any experience with the 4.7, please keep me posted.
