Found the problem...
Looks like the oil was coming through the inner valve cover seal, filling up the coil pack/spark plug valley, and dumping out (the seal that holds the plastic cover on the valve cover isn't good enough to hold in all that oil). I removed the valve cover, reseated the seal (couldn't tell if it was installed wrong, as it fell off while I was trying to remove the valve cover). It didn't look pinched or anything, but who knows. So far so good, but we'll see what happens... |

Good find finally.
Wait, did you change that inner gasket or yours doesn't come with one, I bought Reinz brand and it comes with both gaskets (inner and outer) just need to order rubber grommets extra. |

The oil in the pic wasn't the cause of my initial leak that prompted me to do the gaskets. That pic above is from after doing the gaskets (The valve cover gaskets come as a set, the inner and outer). For some reason it must not have seated properly when I installed it. I did both gaskets, on each side, and all of the bolt seals as well. Once I finally get the mess of oil covering the bottom side of my truck cleaned up, I'll be able to see if my initial leak was fixed by replacing these gaskets. |

The plastic and socalled valve covers warp over time badly,that is why i always use a good gasket maker(like Permatex black)between the head and the gasket and never had a problems like yours.

According to the service bulletin, you're only supposed to use Permatex on the corners of the two half-circles in the back, and where the timing cover gasket touches it on the front. I don't think the valve covers should be warping unless the engine is severely overheated. |

I also put a drop of Permatex every 2-3 inches between the cover and the gasket so it stays in place and not falling.
You have no idea how much the covers are warping even without overheating.Sometimes when tightening the bolts you can see the cover moving 1/8" or so. But what I know,I've did only a few dozens of them |

I guess that's possible. I've just never come across a cover that is so untrue that it will not seat a gasket or seal properly, but not so bad that permatex wouldn't fix it. I don't have a lot of experience with m62's in particular, so I can't speak from experience. |

Yes,i put a bed of Permatex between the head and the gasket.The problem is with inside gasket-there are no bolts to tight it up and it is leaking to the inside.

When you installed the timing chain covers did you do anything to press them down flush with the head? In the TIS it states to use a special tool, something that fits in the grooves of the valve cover then you tighten the valve cover down to press it flush, then you tighten the bolts on the timing chain cover. Im doing mine tomorrow and dont have this tool, wondering if it is necessary.
