VS Exec V6 Wagon
Got a big water leak at the back of my V6. The water is coming out from the drain hole in the cover under the flywheel / flexiplate (its auto) and around the starter motor. Don't know where all the welsh plugs are, but the ones I can see are all ok. Is there one at the back behind flywheel? Also there is a hole at the back of the motor, on passenger side, near the head. There is water spray coming out. Never noticed the hole before (only look when things go wrong). Is it supposed to have a plug / cover in it? The bulk of the water is coming from somewhere else.
Any suggestions??

There is welsh plugs on the back of the motor (4 on the buick, ecotec not sure). Trans/housing needs to be dropped to access them.

That's the best bet ^^^ otherwise when it happens again you will just be doing the same thing over and over. May as well replace the lot and not have to worry about them for another 12 years.

check the plastic fitting on the heater hoes that goes down the back on the inlet first.
It may have crack and is cheaper to fix.
