hello, well I just recently got my first subaru running:banana: (87 gl10 turbo) right after the first start I noticed my coolant getting shot out of a hole on the backside of the intake manifold directly at the flywheel opening (where the timing marks are) can anyone explain where this coolant should passage to? could I just block it?

 

any info would be great:)

Undo the '4wd turbo' plenum and lift it up. Disconnect the air hose from the bottom, and remove it. From there you should ba able to see a coolant hose that runs across the top of the block from the thermostat housing to the turbo itself. This is likely your leak.

 

Other potential leak is the 1/4" hose under the intake to the top of the block. You would have easy access to this hose with a long screwdriver and by moving the alternator up. When this hose leaks, it usually nruns off the back of the motor by the bellhousing, or pools up in the #3 spark pluig
