Z is Overheating

[zbane]

. the head gasket does not seem to be blown but i dont know all the ways to check, i did check the oil and it is not milky at all.

When my head gasket blew, none of the coolant made its way to the crankcase (or at least not enough to be visible). I had been overheating, and had replaced everything you have, including the radiator at 1 in the morning, in the rain. :mad:

Have you checked your compression? That was the final indicator in my case, as well as the car simply refusing to start...

the car still runs pretty strong but i would guess that doesn't mean that one cylinder has a leak in it. i also discovered that there might be some kind of blockage in the coolant system due to the fact that the coolant doesn't seem to be flowing and then the thermostat opened up causing coolant to overflow out of the top of the radiator.

Since you have discovered an apparent blockage, I might suggest a complete drain (make sure the heater controls are set to hot so that the coolant in there can drain as well). How you do this is up to you, but I purchased a Prestone back flush kit and fit the "T" connector on the right hand side of the block behind the "J" tube between spark plugs 1 and 2. Fairly simple operation, cut out some of the old tubing, install, tighten, and follow directions.

Others may have other ways to do it, but I like the kit since it allows you to top off the radiator from below the upper edge, helping force the air bubbles out.

A photo should explain it a bit better.

the only thing that makes it a little weird that i flushed the system back in the spring and i have been driving it since may a couple times a week so it could be a good possibility that the head gasket is blown or i have an internal leak due to the fluid that is coming out of the little k&n filter on the valve cover

If you have water in the oil , get it out of there ASAP and flush the engine with good oil and a new filter. Water in the oil , the oil turns into mayonnaise and is a poor lubricant . Plus if there is oil in the water it will raise hell with the new rad.

is there a way to tell if there is oil in the water i have never dealt with a problem like this before if it means i need to do a rebuild then thats what i will do just gives me a reason to start a refresh on the car

Drain the oil. If it's milky, it's got water in it. Looking at the dipstick wont really tell you if it's got water in it unless it has a LOT.

If the old water pump broke it could have worn a hole in the timing cover which would explain the "Milky oil" in the crank case filter. As the bearings wear the shaft cam move causing the impellers to cut into the timing cover. You can pressurize the cooling system to about 15 to 20 lbs with a cooling system pressure tester and see if it will hold pressure, if not remove the valve cover, look down at the timing chain where the water pump would be. It sounds like a timing cover or blown head gasket.

This does require your attention as it will lead to more seriuos problems.

Thank you everyone for your help! This problem will more than likely not get fixed until this winter because it is not worth fixing when i want to pull the engine and do a rebuild on it. And the transmission needs some work along with a few other things that need some attention. Also the car will not be driven due to the fact of causing more damage.
