Vito Water Probs

Post by vito2000 » Tue 21 Jul, 2015 11:26 am

Howdy all
Just new here, I have a 2000 Vito petrol motor 113 model and have just started getting some oil in the radiator, my mechanic says it may be a welsh plug in the head or similar, has anyone had this happen and what was the fix. The van has done 200ks uses no oil and has never been cooked, I've had it since 20ks and runs very well otherwise.
Interesting is its always had a faint clip-clop sound from around the motor like some kind of actuator running, can only hear when idling and with the radiator cap off when this sound occurs there a couple of bubbles come out of the radiator with a bit of oil, this is after I've flushed it a couple of times ( a couple of drops)
Any help much appreciated
Thanks Noel

Welcome to the friendliest Forum on the 'net.
While I know nothing about your vehicle, oil in the coolant accompanied by bubbles indicates to me that the head gasket has failed. Have you (or previous owners) had any overheating issues with the engine?
This is the most likely cause of head gasket issues on an alloy cylinder head.
The head would need to be taken off, and the head tested to ensure it has not other issues.
A good mechanic should warranty their work. If it were to fail again (or in the case of a Mazda diesel I once had, have valves contacting the pistons after the head was shaved) I would be back to the mechanic 'post haste' to ask what he will do about it. Consumer protection laws do give you reasonable protection.

I hope it is not too expensive.

And on posting in this subfolder.

A W113 (aka pagoda) is not the same as your Vito 113 :dance:

There is no subfolder for the vito's, but you can post in "Mercedes General Info".

When your mechanic talked about a welch plug leaking, this would have to be an internal welch plug (between an oil filled area and a coolant filled area)
Normal welch plugs sit on the outside of the engine block, keeping the coolant in.

But if you post in the general folder, you might get a better answer.

Good luck with your repair.

Topic moved to the Commercial vehicle forum.

Some of these have an oil cooler and part of the oil filter housing. It runs the coolant from the engine though it. If either the casting has a fault in it or the engine has not have the correct (read MB spec) coolant in it then it may have corroded allowing the oil and coolant to mix.

Have a good look around your oil filter housing and see if you can see any coolant hoses?

when this sound occurs there a couple of bubbles come out of the radiator with a bit of oil,
I associate air bubbles in the coolant with combustion gases getting into the coolant. I don't know of any other way this would occur.
Engine oil in coolant as well as combustion gases indicate to me that there is an issue with the head gasket (at least).
I would also expect the coolant colour to change over time if the combustion gases are getting into the cooling system, as well as the need to top up the coolant fairly frequently if the engine is loaded to any extent.
I am not a mechanic, but have worked on our cars for 50 years.

Regards,
Tony

Thanks for the replies folks. I'm not sure if its the head gasket as there is no miss firing when I start it and the motor has never been cooked I've been the only driver for most of its life. There are no external signs of coolant leaking. Is there an oil cooling system through the radiator. I wonder if its a suspect o-ring or seal somewhere doing it

It's a blown headgasket . It can still be driven until you start using a lot of water (ie 4 liters per 100kms) .In the meantime buy a bottle of chemiweld and pour that in. Go around a few mercedes places and get written quotes because it is going to be pricey. The whole power train has to be dropped out underneath the van to access it. Diesel or petrol they are both prone to it.
