Id say either Left bank has a tear in the head gasket on # 5 or with all of the cylinders low/lower, if its a 3.0L its likely a cracked head. They're not super expensive in the new castings with the better valve seats, and I can only guess without hands on myself but, usually that's been the case is a fine hairline crack and its caused a tear in the gasket.
Just had a similar situation with a customer/family members 3.0L, just opposite side, # 2 cylinder. I think he was at 112 with opposing 143 and 138 if i recall. Doesnt mean I am absolutely right, I could be a football field off. But it is rather ironic same symptoms, could be same problem.
Clear crack shown on #2 cylinder
And it went through the water jacket chamber.. which soaked the gasket, one day it just said "nahhh"
New heads (Pair), NO cores as they are new, with Stainless Steel valves and valve seats, assembled (Stage I setup).. https://www.12degnorth.com/product-page/heavy-duty-cylinder-heads-ford-3-0l-ohv-v6-1 if 4.0L.. https://www.12degnorth.com/product-page/heavy-duty-cylinder-heads-ford-4-0l-ohv-sohc-v6
The 3.0L heads are known to crack rather easily, especially if North of 200k miles on top of the fact the exhaust valves and valve seats themselves are complete crap.
It's a 98 B4000, so it's the 4.0, not a 3.0 and it has 112k miles on it. it's lead a hard life. I push it probably too hard. I've moved and now own a small farm, and I could really stand a full size truck... but use this like one.
My mistake, I thought you said it was 3.0L to start, my apologies.
Both are similar OHV designs and had similar issues. And 112k isn't a lot of miles in my definition but it is an earlier 90's Ford product. I've seen first hand how short of a life a Ford Product has in the snow-belt.
I usually like to use @Undertm8ed earlier '93 Ranger w/4.0L OHV for a good example, that rig had 362K on the clock the last time we saw the truck out of storage and most of that was offroad mileage, he lives in a bit of a more remote place here in Nevada now so not sure where the mileage is at now or if it's still be driven like it thinks its a Honda HB.
I would say unfortunately the next step would be to pull heads and take a physical inspection but if its your daily grinder and work vehicle, and you find out the heads are relatively done for, that could be a 1-2 week turn around not afforded to most people right now to deal with.
Hopefully you can get a quick resolve..
