Hi there,

I have a 78 Celica with an f20c. This morning I filled the radiator and noticed it was taking alof of coolant. Then I decided to stop and start the car up. It ran for a few minutes and then I saw coolant spraying out of the breather hose. I took out the drainplug and lots of coolant came out. I noticed that all the coolant from the radiator went into the crankcase. What would make all that fluid go straight from the radiator and into the crankcase?

Please help me diagnose this before I start the teardown of my engine.

Any help is appreciated.

Thanks

 

1) Blown headgasket 2) Cracked cooling passage

That's about it. I'd suggest a compression check and a leak down test.

 

those listed above, or perhaps a slight chance where you have oil crossing over with coolant, such as the oil cooler. If you are boosted or really high compression you may have a cracked cylinder caused by detonation.

 

 

thanks for your help guys. The motor is completely stock so I am crossing my fingers and hoping that it doesnt have a cracked head.
