Coolant in valley, worth worrying about?

[acarmody]

While changing my intake manifold gaskets I saw this, not much but I guess it still shouldn't have been there. It was there last time I changed my gaskets too, so I don't think it was them.

Should I worry about this much or not? I can't see any visible when I drop the oil. Nor can I see any oil or foam in my coolant.

Id say its run down there out of the inlet manifiold when you have lifted the manifold off. It probably did the same thing the last time you changed them too,which is why it was there last time.If it was leaking coolant like that while the engine was running the engine oil would get that white milky look about it.

Oh good point, thanks for that.

You will, of course, be changing the engine oil after you have run the engine with the new gaskets to get the coolant contaminated oil into the sump?

Of course, dropping oil tomorrow morning. The reason I changed the gasket is because its burning oil, but has only been happening since I changed my lifters, so thought maybe I screwed up these gaskets. Got some aluminum one from MACE, banged them in, and while I will need to change the oil and monitor it, it has solved my shitting RPM dropping problem (tries to stall when I come to a stop, and has stalled a few times. Auto BTW), and I think my fuel economy is better, but I will need a few weeks to verify this. So my guess is I had an air leak/gasket split in the old ones.
