Raise your hand if you have done that on a newer 4WD Expedition. Okay, you know what I'm talking about. I had to take a frame crossmember and the front axle loose to slide the pan out from under the oil pickup.
This seems to be a Ford thing... lol.. I had a '86 Ford Scorpio when I turn 18, first car, and did lots of stuff on that one. One of which was to replace the gasket on the oil pan, which also required you to drop the front crossmember to get it out. (Scorpio is the EU version we had in Norway of the Ford Granada, which they had in US but not sure if they sold much over there.)
That is on the list for this evening! I'll let you know how it comes out.
And I had a friend with a Grenade--uh-- I meant Grenada! No, it didn't explode, but when a kid doesn't get the car he wants, he gives it rude names (even though he really loves it deep down). I thought it was a great car!
Also, I know how it goes over there sometimes, so I hesitate to say that my stepdad is Suomi (Finnish for you other Americans). But that doesn't mean we can't be friends!
No worries, Norwegians and Finnish people are good friends. It's the Swedish you have to worry about! Haha! Nah, us Scandinavians generally go very well along with each other..
Checked out the oil passages, and guess what I found!
If you can't tell, these are pieces of the older chain guides. I could tell that someone had taken the front of the engine apart before, and now I know the reason. These were stuck in the big passage on the passenger side near the top of the block. This one:
But it looks clear with those pieces removed.
This may have contributed to the problem. I imagine that it would significantly reduce the flow from what it was designed to do.
Wow.
Here's an example of an issue that you could get all kinds of suggestions and feedback here, but until you pulled it apart, who would of known?
Great catch!
Great to see that you found something. Blocked oil passage to the heads was one of the suggested things, and I'm happy it was only that. Now you can bolt on new heads and feel confident that they'll last. I'd imagine the disappointment if you didn't catch this and had the heads fail again due to oil starvation...
Yes! Exactly so, Skauber! And I wonder if the signs on the heads are showing correctly. I thought I was imagining things, but the passenger side head was just a little darker, the cam lobes tell the story. but more on that later. For now, the first of my new parts have arrived!
Aren't they pretty? I know it's a roll of the dice on performance, but I have never liked having a lump of iron instead of tubular steel for exhaust. if nothing else, they save a few pounds.
Yeah, they won't do much on performance without diving deeper into the tuning world, but they sure look pretty! A stainless steel exhaust all the way is really the best, no doubt about that.
Im working on the same issue in my navigator right now. there were shavings coming out the oil passages in the cam journals and managed to do the same damage to atleast one journal. It all started with the same chain guides breaking and blocking the oil pickup tube and starving the heads of oil, ultimately snapping the cam chain (DOHC). The oil pickup tube (screen) was completely blocked. I replaced the oil Pump as a precaution, and am in the process of putting it all back together. Not Fun.
This is why I want to get metal guides and metal ratcheting tensioners when I am gonna replace my timing components. I really don't like the idea of having plastic in there, and broken pieces blocking oil flow is one of the major reasons I don't like it. Another one is the fact that the guides can snap and make the engine go so severely enough out of timing that it can effectively destroy the engine. It's totally crazy to cheap out and put plastic parts on something that critical in my opinion! In that case it would be better to just make a timing belt system and have it easier replaceable with a service interval.

Ouch! We can share the pain. At least we are able to turn a wrench. I see it as paying myself instead of a professional mechanic. Nothing against them! I grew up in my dad's own auto & welding shop, so it's just hereditary for me. Saves me money.

Now there's something I didn't know existed yet. What a great idea! I'm glad you said that, because now I'm going to research and try to make sure I don't have to tear this thing down again. I know they say with proper oil and filters it should be fine, but I still like to improve over the original design when possible.
