Oil in the radiatorand over heating HELP!
Hey everyone back again. I have a 92 s13 with a redtop sr in it. I tore the motor down and put a Cometic 1.2 mm head gasket on it along with ARP headbolts and greddy rocker arm stoppers. Now here is the problem: ( By the way I have archived this topic) After a few days of driving my car I found that it would sometimes over heat and fluctuate up and down. So I bled the system to the best of my abilty several times. Still overheating. I did not have a resevoir so I put one in. At this point the overheating is progessively getting worse. I must add that when I did not have the reservoir that there was no coolant coming out of the overflow tube. Upon adding the reservoir it now boils over. So next I removed the T-sat all together thinkin that there could be no way it could still over heat, I was wrong it still does it. My water pump is not leaking and it is flowing water I can tell this beacuse I see it flowing quite fast with the radiator cap off. It seems that I can never completly bleed the cooling system there are always bubbles coming out. Small like Alka-Seltzer and some big ones. I have also replaced the radiator cap checked for leaks on the IAC valve, heater hoses, and others. I have also blocked off the factory coolant lines going to the turbo. There is no white smoke coming from the exhaust. I just did a compression test last night and they read 155,155,155,155 consecutively. Cecked them twice, then checked another car to make sure it was right. Now the most recent problem is oil in the radiator, this problem just arose. I am at my wits end .......................Please help! Thanks Jonathan
With the heater on "HOT." Raise the front end up. Undo the one bolt on the water neck (has that yellow sticker under it). Fill till coolant comes out that bolt opening. Replace the plug back into the hole. Keep filling through your radiator cap. Fill it till it comes all the way to the top and recap your radiator. Squeeze the upper radiator hose repeatedly and now check under the radiator cap. If the level goes down, keep at it. If it's stable, lower the car back down if you want, but start the car. Squeeze the upper radiator hose while it's going. I usually keep squeezing for about 30 seconds before I shut down the car and let it cool off a bit more then back to squeezing and refilling until the system is packed with coolant.
I have seen this a couple different times with differnet failures. Check your oil cap for the milky look. I have seen milky caps but no milky look to the oil on the stick.
The couple I saw was as a result of a head gasket allowing the oil to pass into the coolant system only on cold start up. The other was due to a pourus head on a new vehicle. In both cases coolant was not passing into the oiling system only oil into the radiator. Another oil into radiator failure which is more common is the automatic trans cooler had a leak but I am sure yours is a stick and you dont have any oil cooler in your radiator right?
In neither case was the car overheating though, this leans me to the whole bleeding the system properly thing.
