HI All,
My helper overheated the engine (DT 466E in my International 4700 truck).
After overheating, the truck started using coolant (has to fill about 2 or 3 inches of coolant into the resovoir tank per day but no steam out exhaust pipe).
Oil is NOT milky so no coolant in the oil BUT dipstick showed signs of moisture / rust towards the top of the stick.
Running that way for awhile and then the truck started to miss so we assumed head gasket blew and parked it.
Helper noticed signs of coolant residue on passenger side of block towards the rear.
We hope it's just a head gasket and started taking the engine down BUT later I read that it is possible to have leaks on the bottom of the removable cylinder liners ....
How can you tell if is leaking from the bottom of the liners ?
I'd hate to change a head gasket and put it all together only to find it is leaking on a cylinder liner and have to take it all apart again....
Is it possible to just change out the bottom liner seals without having to take out pistons etc?
I know a rebulid is possible to do when sooo far apart but engine was fine until overheat and I am not made of $$ so If I can cure the problem with just a head gasket that'd be great BUT if I also need liner seals I cuuld do that too BUT I am just trying to get it back on the road for a minimum of $$ and time.
Thanks in advance for any and all help.
