Thread: 2.7 TDV6, a wee bit of a problem, possibly......

If you mean the Y piece on the intake side that sits in front of the oil filter..Its very simple. about 30 mins if taking it easy.. just find a thread about doing the EGr blank and it will have a step by step of it. If no joy I will find the one I used.

Seems feasable about the oil sitting on the coolant, would think if it was a new leak it would be clean oil. I am unsure of the coolant hose's in that area, but have a workshop disc so can check it out if no one comes on with a decent response.

Cheers Ean

Hi Ean,
I found the EGR blank procedure, this is good, however doing the EGR blanks you don't actually take off butterfly box, the air box comes off and the EGR pipes, I was hoping to get the buttery fly box off without taking both EGR pipes off.
If you have got the procedure for taking off the butterfly box that would be appreciated.
Thanks for the help rendered.

All you need to do is about 100mm from the airbox on eack EGR pipe is a join, there is a small clamp like a hose clamp that with a pair of pliers you just nip the 2 sides together and that clamp can be removed, this allows the EGR pipe's to be seperated.

Once you take them off ( keep them as you just fit them back on when you refit the Y piece) have a look in the centre of the Y near the oil filter there is a electric connection, pull this up gently ( it just sits in a groove) this will only move a small amount, its just so the connector is not broken when you remove the Y piece as the groove is moulded onto it , then lift the whole Y piece up and it just pops out of the inlet side, as it is only held in there by O-rings.

The whole Y piece is held in place by 1 bolt about 1/2 way along and the clamp ring at the front end, the back end just fits inside the larger inlet section between the heads.. You dont need to worry about the steps of the butterfly removal as that will all stay together....You will be shocked at how much crud is in the Y piece tho.

Hope this make sense.

Try this.. may help abit. dont try and remove the EGR pipe's from the Y piece as they go inside about 50mm, just seperate them at the join I mentioned..Very easy, looks daunting but if you look closely at the little clamps that hold them together, you will see how they work.. I never fitted new O-rings, and have removed the whole thing twice so far. Whilst you have it apart, remove and clean the MAP senser in the Y piece, its held in by 1 screw

It may be the thermostat housing leaking. They are plastic and warp first leaking a bit then fail. Just had mine replaced.

Hi CaverD3,
What symptoms did you have? Slight loss of coolant at first? Water in the valley? (sounds like some sort of Welsh ditty), water leak underneath? Did you do it yourself? How much was the thermostat housing?

Only a couple of questions I know........... Thanks in anticipation.

Hi Ean,
Great help, thanks very much.

I think with where the thermostat sits it would be hard to have coolant in the valley if the housing is leaking.

Here is a copy of the coolant system, just need to see which is yours..manual or auto

Cheers Ean
