Hi Guys,

Some may have seen it on trademe, but I bought the NZ GT Ae82 liftback that was suffering mass water exit.

Initially I suspected water pump as seller was a bit lax on details, but since a mate has picked it up and had a look, it is losing water from the back of the block and he says 'within' the bellhousing.

He suspects its the very rear frost plug that has gone, removal of trans backing plate, revealed more water in bellhousing, and surface rust on the flywheel.

Just wanted to check in and see if anyone has suffered a similar fate?

anyone had mysterious leaks on a 16v 4age - not the water pump?

the only really evil one I can think of would be cracked block ... which doesn't really bear thinking about.

within the bellhousing as in the gearbox bellhousing?? no water goes in there?

could possibly be the rubber hose that runs from the back of the waterpump to over by the thermostat housing (if 16V's are the same as 20V's). it is a bitch to get at and could be the problem

There's an oring that seals between the block and water pump.
One weird one I had on a AE82 GT looked like it was leaking from inside the cam cover.
Turned out to be a crack in the alloy water pipe on the firewall side of the head. Was running down that along the cam cover and out the bottom...

I also had that issue on my AE92 parts car motor, also turned out to be a cracked pipe that runs along the rear of the motor from the water pump

Yeah that can happen, in my case it was the radiator hose outlet:

cambelt side of the engine is dry as a bone apparently.

When he pulled the dust plate off that sits between block and gbox, water came out of there, and it appears that water is coming from this end of the block.

A quick look at diagrams of the 16v 4age, shows there is a frost plug on the gbox end of the block.

For some reason I saw your second post and thought it was someone else asking about weird leaks.... I'll go take my meds now...

Frost plug it would be I reckon.
Plus BHG! :lol:

by **xsspeed** » Fri Mar 25, 2011 11:03 am

no oil in the water and is sweet to run - well until you have to turn it off as all the water disappears - so I am hoping the HG is sweet

This motor did suffer a previous BHG, and was repaired - head planed apparently - not saying that excludes the possibility though.

I was throwing the MAGN1T card

Even if thats the case I got the car for a song, so a replacement motor isnt adding too much to my costs - sourcing one is the hardest part.

I suspected this, but could not pick up your tone
Clearly BHG then

Yeah see pics, looks like its leaking between the block and gbox

The guy checking it for me reckons thats dry also (pipe runs under the intake runners from memory)

I've had problems with a BHG on a 16v and it was the back right corner of the block that was the problem not the head. Maybe the last time the HG was done the block needed planing and not the head. Have seen the same issue on a couple of other 4AGE's too.

It shouldn't have water it it anyway, should have antifreeze. Putting water in just makes the leaking gasket leak even more as it rusts.
Makes a leaking frost plug worse too.
