1: Should I drain all the oil & remove the filter to do the oil cooler seals?
2: Where might the oil at the front end of engine be coming from?
3: In the last pic, there seems to be a gap that the arrow is pointing to. Does this look normal?
thanks
Full Version: pics of my oil leaks
I took some pictures of my oily engine and wondering where it's all coming from.. I ordered some new valve cover gaskets, push rod seals & oil cooler seals but it looks like there's also oil coming from the front end of the engine too? I'm trying to fix them all while I have the exhaust system off the car.. Here are my questions:
1: Should I drain all the oil & remove the filter to do the oil cooler seals?
2: Where might the oil at the front end of engine be coming from?
3: In the last pic, there seems to be a gap that the arrow is pointing to. Does this look normal?

My guess: classic push rod pubes seals.
Heres a few things I notice by the photos. . .
1. The oil cooler is soaked like oil is blowing through it - likely the front main seal blowing oil through the cooler fins.
2. The bottom of the fan shroud is soaked, especially on the bottom - see #1
3. Oil running down the case above the push rod tubes - see #1 again
4. Lots of wetness on both ends of the push rod tubes - change all the o-rings with Vitton replacements and carefully clean the bores that they fit into. Any crud will cause more leaks.
The gap in the shroud is just the way they are cast. There's no gap further up the seam
Since you will likely want to pull the motor/trans to replace the front main seal, that's a good opportunity to do the rear main and the oil cooler seals as well.
Beware: This is the exact series of events that cause some cars to be relegated to jack stands for years and the draining of retirement accounts while a full resto ensues. . . Focus, & STAY AWAY FROM THE LIGHT!!

Take it to the local do it yourself car wash. Spray some cleaner on it after it cools, and powerwash all the gunk off. Zeps Citrus degreaser works good, and it's cheap. You can get it at Home Depot. It won't tarnish the case like Gunk and other products will. Just don't let it dry on. Should help identify all your leaks once it's clean. Just noticed, looks like your exchangers are off. Not sure you want to spray water up in there then.
Seriously, It is easier than it looks and worth the effort, You don't necessarily have to pull the engine but in the end it would be easier.
