So I just finished putting together a b16 and i started leaking oil from my cam seals. As I was replacing them, I noticed that my oil was milky. I drained my oil from the motor, replaced the headgasket, and put coolant in the radiator. put in about 3/4 of the coolant mix and I am noticing that coolant is coming straight out of my oil pan. When I took off the head, coolant passages in the block were still holding coolant. What could my problem be?

Thanks

 

So you're saying as you are pouring coolant into your radiator, the coolant is coming through you oil pan drain bolt?

 

yes, coolant goes into the radiator, comes out of the oil pan drain plug.

 

head gasket!!!!

 

Not to sound like a dick but I have seen it. Could you have put it on upside down or backwards? My buddy did it. Or there is a crack somewhere...

 

I mean, when I put the head gasket on, the up is facing.... the head. The head was a lsvtec head if that makes any difference? I was told it could've been from dowel pins also?

 

and also, the coolant passages in the block are holding the coolant fine.

 

would you happen to be running a oil cooler like the factory one on a b18c1? It has been a long time since i have looked at a B16 and cant remember if they run it or not. It looks like a spacer infront of the oil filter, with 2 hoses coming from it

 

no oil cooler. coolant fills in the block
I think as soon as the coolant fills past the block into the head it leaks out the oil pan as fast as I pour into the radiator.

 

GSR's do not come with oil coolers from the factory.

 

I have seen people hook yp the coolant lines coming off the coolant pipe in the back of teh motor incorrectly. Runnin them from the coolant pipe into the manifold instead of to the IAC valve.

Just a thought

 

This or your block is facked.

 

its either a good-sized crack or a coolant hose routed improperly. even if it were a bad HG or uneven mating surfaces the fluid would not poor out THAT fast

 

That hella scary.. Was that rebuild engine or used one?

 

cracked block somewere!

 

definitely sounds like a cracked block.
