Be sure to get all the plastic debris out of the oil pickup or it will definitely be on borrowed time.
The plot thickens: I pulled the pass side valve cover and, lo and behold, the rear guide is intact and doing its job. I need to check the front cam guide, but boy am I tempted to try to fix these things in the truck and just button it back up w/o pulling the engine. Things looked really clean under the valve cover.
Oh, and adding to all this: the motor I had found locally turns out to be from a RWD vehicle (no balance shaft), and when I checked the VIN from the Explorer it's coming from, I discovered that in 2013 the mileage was at 155K -- that's 3k more miles than my current engine. Not sure it would be worth swapping.
Man, I am kind of stumped. Sort of tempted to try fixing what I've got and take a gamble... maybe swap out the oil pump too, if it's not a real PITA.
Have you given any thought to removing the chain altogether?
I was tempted.
Hot damn -- my cam guides are both intact! My luck has been too good lately... not that I'm complaining. Now I just need to figure out how to replace that balance shaft chain tensioner w/o too much hassle. Life is good (for now, anyway)!
I regret not doing something about mine but have no plans of removing the front cover again. I will be removing the pan and probably the cradle soon if it's not too much of a PITA
Well, you know what they say, "If it was easy, everyone would be doing it".
I've been giving some second thought to my decision to leave the balance shaft chain with no tensioner and I'm getting a little worried that I didn't address it when I had it apart. I'm looking forward to seeing how it goes with removing yours.
You've got that right (the "if it were easy" part). I plan to pop the chain out tonight and start cleaning & buttoning things back up. I did lots of reading here and sound NO instances where deleting the balance shaft created issues. Someone said two junkyard engines w/o balance shafts were installed in a 4x4 and later blew, but there's no way to tell whether that's a balance shaft issue. Others report a fine running engine for tens of thousands of miles.
I'll keep you posted!
