Question about 1998 Chevrolet C1500
Posted by Anonymous on
If you haven't found the problem already. I suggest looking at the drivers side radiator tank they usually crank and seep slowly. If not leaking there, it's probably the intake gasket. Both of these problem are common to this make and model.

check the condition of the reserve tank and the hose from the reserve tank to the radiator for leaks if no leaks there have the Radiator cap presure tested . also this could be a air lock in the engine if the radiator is new with the engine running and the heater on hot observe the fluid level in the radiator with the cap off if it drops as it warms add more coolant this will purge the air .

This is one that you will need to do some careful looking to find. every hose connection needs to be looked at for damp residue as well as all gasket parting lines (thermostat housing, head to block parting lines, intake manifold ends etc.) You may also need to have a shop to a radiator pressure test as well as a cylinder leakdown test (which will pick up on most internal leaks) If seepage is very minor, coolant can burn off or boil out before reaching a noticeable level inside the engine or even at a gasket to the outside. A small crack between the valves in a cylinder head can be so small that it goes unnoticed when exiting along with exhaust. A small leak now may be difficult to find but locating it now is better than waiting for a larger failure. It may turn out to be something simple as a bad cap on the radiator or the shaft seal beginning to fail on your water pump...letting it go can eventually cost you an engine.

check for a wet tailpipe,which might indicate a leak between water jacket & combustion chamber.i.e.headgasket.check heater hose isn't leaking onto exhaust manifold,'cooking' the anti-freeze as it leaks.

If you have steady thick white smoke and it smells like anti freeze it is most likely the head gasket. The head gasket can fail in different areas. If it has white smoke it failed between a coolant passage and the combustion chamber. If the oil is milky it failed between the coolant passage and an oil passage. Just because the oil isn't milky doesn't necessarily mean that the head gasket it's blown.

I'd be tempted to live with it depending on whether the vehicle is using coolant on the assumption that it is condensation causing the saponification of the oil. If the Lucas oil treatment caused the pressure to rise so dramatically I would suspect that some crud has come adrift and lodged in the pressure sender.
The chance that the cylinder head is cracked would be more rare than a leaking head gasket both of which could possibly be tested by a leakdown test of individual cylinders.
The water has to come from somewhere.
Does the soap go away when the engine is warmed up?

Testimonial: "Good point on the pressure issue, not using coolant. Dip stick had rust on it and so did the inside of the fill cap. Hot or cold white on the stick."
