A Bit of Cavitation

Digging around, I've seen alot worse, but should I be overly worried about this? Obviously, I'll be more diligent about the coolant from now on, but I'm at wit's end with this truck, and really don't feel like pulling the cover too.

it will get worse , once it starts its only a matter of time. you can get a new updated version that is a modified casting to stop this , but you wont hear ford saying anything about it. im going to add the updated one when i pull my can for a big preventative maintenance overhaul,

can i ask why you pulled the water pump? just checking or did you have issues? im gussing mine is like yours, im at 170k on the original one.

My oil cooler pushed a bunch of oil into the coolant. I've replaced that, but the water pump was leaking out the weep hole, so I'm replacing it. I'm at 176k.

wow, So it sounds like a good idea to do the oil cooler at the same time when i do the rest of my preventative maintenance ,

did you fined an updated oil cooler that is better built ? or aftermarket HD built?

I don't think there is an updated oil cooler. I just got a Ford replacement. I'm going to try filling the pitting with some high grade epoxy.

replace that before it gets worse, eventually it will eat all the way through.

There is an updated front cover design with a flow restrictor cast into the area behind the water pump.

I was going to use a more robust version of JB Weld from a company called Belzona, but the crap is about $300/kg and doesn't come in small packages. It's actually meant for repairing stuff like this in large industrial pumps. Instead, I tried Marine Tex. I've heard of guys using it with positive results in old muscle car timing covers. I'll pull it apart in a few months and see how it looks. I have other things to spend $500+ on right now, so $20 to maybe fix something that isn't too urgent is worth a try.
