I have just done an oil cooler replacement but the bad news :'(
Is there is coolant dripping from the bottom of the bell housing
So where is it coming from?
There was a coolant lose before I did the oil cooler
I am thinking there are 4 possible
1 heater pipes
2 oil cooler plate
3 the bridge
4 the coolant outlet pipe just above the bell housing
The first 3 not to bad to do, but the outlet pipe seems impossible
To get to.
Has any one ever tried to use a small cam to look round the back and down to see where the leak is or maybe from underneath by putting the cam to the top of the bell housing.
Any ideas or comments will be most appreciated thanks
-
Heater bypass valve, it is at the back of the engine and is generlly the biggest culprit
-
Is it a 1998 model? ::)

It does sound like hbv to me also, and as the car has been sitting on your drive for the best part of 18months it could well be fubared due to inacctivity and the seals inside may well be perished due to oil contaimination. You will find it behind the left hand side head and you can get better access to it with the plenium removed. It has three pipes and one vac pipe on the top.

It leaks from the main body of the valve where the top joins the body.
No repair is poss and replacment is the only cure. use gen vx valves and make sure the part has the part no stamped on the top as a few without this were supplied to vx and failed within a few months.

Hmmm, is last letter of VIN a W?
-
just spent 2 hours setting up a cam and TV to have a look round the back and after many manifold burns I can say for sure it not the hbv
IV looked at the top of the bridge and no water coming from the left hand side of the oil cooler plate and I have looked down on to the coolant outlet pipe and is dry on the top
Is not so easy to get the cam down the right hand side
But I can see water not sure whether it sperting or pulse dripping from
Just where the oil cooler pipes disappear behind the back and up over the bellhousing
So it seam that is Cumming form the left hand side
Im going to make some sort of twisty handle so I mite get round the right hand side
-
yes the last letter of the VIN is a W

ah, sounds most likely the transfer pipe, or one of the rubber pipes near it then.
-
Iv already looked from the left hand side with a small cam at the hbv, coolent bridge, heater pipes , top of the transfer pipe (is that the big silver pipe that come from the center of the block) if so iv looked at the top of it and cant see eny leaks
l but Ineed to make some sort of handle to get round the right hand side as it a lot tighter to get in.
-
maybe the transfer pipe is leaking on the underside an I cant see it from the top
-
So what is the theory about 98MY engines (or could you refer me to the thread please) as mine too is this year. I have replaced or checked every potential leaking joint including the transfer pipe and whilst I no longer have coolant dripping off the nearside belhousing bolt I am still loosing it (half an inch from the header in a week and about 120 miles). Convinced myself that it could be air in the system but not if the level drops again. I do have a fair bit of mayo in the filler neck (which reappeared in less than a week after cleaning) but I know this is not unusual. I don't believe I can ever remember it being as bad as it is now previously though.

The mode of failure is not traditional HG, but simply a leak from waterways to outside. If its not dripping from engine, unlikely to be HG.

look like bad new to me just have removed the heat covers to the manifold and with the cam I can trace the leak to the right hand side at the back of the block just next to the t end of the manifold this will be where the head mates with the block it looks like the boy has it sussed if it is this is there any other symptoms
