Hi All,
I'm a little concerned about my new '89 Maverick SWB TB42 Petrol/LPG.
There has been a slight coolant leak appearing under the car in the
vicinity of the bell housing area. I havent been able to find where
the coolant is coming from...but today felt around the back of the
head and I can't see anything but it feels like there is a Welch plug
there? The plug felt like it had some corrosion on it but no moisture
apparent. It is only a small leak so that may be the source?
Also I have noticed come carbon like deposits and condensation coming
from the exhaust...
The coolant in the radiator looks clean - and I changed the oil and
oil filter yesterday - the oil looks clean also.
Has anybody got any thoughts or experience on this?
Thanks very much,
Luke.

Luke,
As the others have mentioned it could
well be the welch plug on the head, I can only assume that the engines in the petrol & diesel are similar.
Mine had a slight drip from the bell housing drain, if the leak is coming from the bell-housing drain it could
well be the welch plug at the back of the engine block, this means the engine will have to come out, no options. The way you talk about the leak it sounds like you can feel it so thats good. If you have a small mirror you can squeeze that between the firewall and the head and if you get the angle right you can see what's leaking.Keep the shiny side up

Thanks for everybodys replies so far.
Took it down to the mechanic today. It most certainly is the Welch plug at the back of the head.
I've elected to take the head off and get it checked out instead of just trying to fit a new Welch plug....
They'll do valves, guides, seats etc etc as
well as welding up some holes, and drilling and tapping the head for another coolant line.....
After all this, assuming the head's not cracked when they get it off it should be more durable.
All I've got to do now is come up with $1000 and hope the head is OK when they get it off......
