I have a 88 f250 with a 7.3 idi. I have a coolant leak and all hoses appear good and recently replaced. The only place I see coolant is on the valley pan. Any help is appreciated

 

how much and how long does it take to accumulate ?

 

Just started yesterday. So I don't really know. I would say it is close to a quart

 

Good morning and Merry Christmas to all.
i have a 88 F-250. 7.3 idi. I have noticed a coolant leak around the number 7 glow plug. I soaked up the coolant and pressurized the Coolant system and coolant imeadily came from around the glow plug. This is the only leak I discovered.
Any suggestions.
Thanks in advance

 

Is it cranking and running fine? White steam out the tailpipe? Bubbles in the overflow tank while running? Pull that glow plug and see what's really going on. That would sound like a head gasket or block worm, but if you're pressurizing the cooling system to where it's pushing out of the GP, that (in theory) would be putting a lot of coolant into the cylinder, unless it somehow cracked between a cooling passage and the GP threads.

 

Thanks
yes white steam from the tail pipe and loosing fluid when running. Otherwise runs fune. Only has around 150000. So in other words it's not going to be able a easy fix like I was hoping.

 

Had the oil cooler gaskets replaced a week ago the mechanic noticed a piece of metal inside the block when he took the rear header off. He said that concern him but the truck ran well and he didn't notice any leaks or anything that seemed strange at the time.
Next question is if I have to pull the motor should I resleeve all of the cylinders

 

Two things:
1. You are *sure* that the coolant is coming from the glow plug(i.e. remove glow plug, pressurize coolant, it comes out GP hole). It's not coming from somewhere else(there are coolant passages that stop at the intake manifold), right?

2. More than likely, you will just pull the heads, clean off the old gasket crud, reassemble with new gasket and be fine. These gaskets don't last forever.
Obviously, when you look inside there, you might see other actual problems, but just having coolant leaking through the gasket doesn't mean a motor rebuild.

 

Thanks I didn't remove the gp but I will. It appeared to be a coming up around the threads. I will try by taking them out. Thanks for the info
