water boiling on manifolds

I've just replaced my rocker gasket a few weeks back now I'm getting a water leak just above the manifold…can it be my gasket instal was not done correctly?

Does this pic help?

cheers jez      

There should be no water anywhere near the rocker cover, just oil. there is water running around the inlet manifold so the leak could be from there, your water looks very brown what is it like in the radiator/expantion bottle?
If you make a mistake fitting the rocker cover gasket you just get oil running out.

What car is it you have? I hope its a carb as that's the one with water in the inlet manifold, injection there is no water in the inlet manifold…

That's what's confused me..cool ant does look Brown ish…  Any other suggestions to diagnose?

More water seems to be coming out from somewhere when the engine is t unfed off. Fan is working..

Yes it its a 1.8 clipper carb.. Original carb i have a Webber just never got round to fitting it...could it be water its coming through the manifold some how?

If the carb on there is working fine I would not bother changing it for a webber, wait until it starts playing up.
Check to hoses and jubilee clips going into the manifold for leaks if there fine there is a gasket and grommit between the manifold and the head, I think the carb version has water coming in from the head to the manifold. You will need to take the inlet manifold off to replace it.
Flush and change your coolant, it should not be brown!

Gasket looks like this, I think the top hoop has the water coming through, is that where yours is leaking, between cyinder 3 and 4?

It looks to be coming through near a metal plug thing  3 and 4..  also looking at the Oil cap its at jk quite milky i did wonder if out was the head gasket as well or instead?

Any suggestions of the order i should test or just starting changing things?

Manifold gasket and plug?
I have a small hole in exhaust manifolds end so do this as well
Change Oil to see if it still turns milky
Flush coolant
wait for results?? Before considering head gasket

Cheers for all the comments

Then test again

Hi,

I'm not quite sure what you mean but it could well be the headgasket if the oil is milky and you've got a water leak.

The first thing to do though is to clean it all up and get a new gasket and oil ring on the inlet manifold.

This is a quick job, except for removing the manifold bolts which are quite hard to locate. You need a hex key (6mm?) on a long narrow extension and a mirror to see what you're doing.
I did this a couple of years ago, and sandblasted the inlet and exhaust manifolds at the same time, and now in all looks a lot cleaner, even two years on.

You also need to flush and replace the coolant, which should be transparent.

You can get mayo/cream on the oil filler cap if the car has just done short trips, this is normal., if you are still getting mayo after a good 10+ mile drive then there is a problem with the head gasket.
Check this first then if the mayo goes change the inlet manifold gasket and gromit.

Ok good advice I've also got a small blow from the exhaust manifold end.. What's the advice on a replacement? Stainless steel?

Cheers Jez

Just took it out for that 10 minute spin and managed to locate a hose leak..   Hoping this is the root cause and I can leave the manifold gasket to another decade !!

This is the number I can make out on the hose   026121062B   Anyone think this is NOT the correct part from VW heritage ?  Reminder I've got a standard 1.8 Clipper carb with origional Carb.

After the hose is replaced it looks like it's time to:

flush coolant
change oil
go for a 30 mile drive and see how the oil and coolant are

Cheers

LOL just seen that Heritage says it's a special order.. so  7 weeks !!  The ebay internet hunt is on…

All advice on where to get a replacement very,very welcome.

Cheers
Jez

Have you got a picture of the hose?
You could always try phoning a VW dealer, as you have a part number they should be able to look it up and see if its still avaible and there prices are sometimes cheaper than vw heritage.

is it any of these;

Thanks I've bought the c version from b andb   looks about the same..cheers all..

Right the hose is now on coolant flushed and no boiling water in the manifold. When i start from cold i have noticed some white smoke from the manifold area but it goes away after a few minutes

Anyone ever seen this?   The original carb seems to rock on top of its mount only really kept down by the air box..does not explain the smoke at start up only but all things maybe worth mentioning.

Cheers Jez

Hi,

a little white smoke on initial start up is fine - it's just the remaining coolant burning off - but it shouldn't smoke next time you re-start, or else you still have a leak somewhere.

Whenever I do overhauls, there's always smoke from engine degreaser, new paint, oil on exhaust, etc, but never for more than a minute or so.

The carb shouldn't rock on its mounting. It should be possible to move it slightly,but if there's a lot of movement the rubber will be perished and need replacing. It's a quick job and cheap too.

Robin

Thanks does this look like the right part? http://item.mobileweb.ebay.co.uk/viewitem?itemId=390543991215

Yes that's the carb mount. GSF also sell them as do some other places.

the white smoke could be down to a slight coolant leak onto the exhaust manifold, my old mk2 1.6 did this due to the coolant channel o'ring in the inlet manifold. Get this swapped if you havent done so already

Could I still be getting oil in the cap if it's not the head gasket and just the manifold?

Thinking of getting a pressure test done if this will help the diagnosis.

I've started a different thread on the same topic now.. so maybe best I try and kill off this thread as it's about the same issue to be honest.
