hi all new to this site
ive just brought a 97 vs with a suspected blown head gasket other people or telling us its a blown valley gasket or a welsh plug the motor oil is a chocolate milk color my boyfriend drove it 40 ks and didnt over heat or loose water i spoke to a mechanic he said the vs are prowned to heads cracking its done 194000ks
and where abouts are the engine # located on the motor
hope to hear back soon

Ive never heard about the head cracking thing,but the inlet manifold gaskets are known for blowing out or leaking. And to a lesser extent the head gaskets.Its most likely the inlet manifold gasket has blown or leaking.They are fairly easy to fix though .You can also get the engine compression tested and get the cooling system pressure tested as well.These tests will show up anything that is wrong with the gaskets etc.These tests are cheap to get done ,and about the only real way to tell what condition everything is in..

It depends how bad the blow out is, and where, blown head gaskets 'can' warp the heads, which they would then need machining to make them flat again.
A blown manifold gasket is a lot easier to repair, and less expensive, and is also a possible cause for loosing coolant and getting water in the oil.
AS for the engine number, try this thread-

thanx all we in the middle of taking the valley off stuck on the allen key bolt and also noticed the radiator has signs of oil in it we drove itr about 40 ks n didnt lose water or coolant n didn't over heat

Yeah try soaking that allen key with WD40 or RP7 or something like that for a while, before trying to undo it, steal bolts have a habit of snapping off in alloy, so go slowly.
This 'could' be a good sign, if you're not 'loosing' coolant, or oil, then it's possible the coolant & oil are just being transferred through areas in the intake manifold where the gasket has has been compromised, hopefully meaning it's not a head gasket.
ps- I shouldn't have said water in the oil last time, should have said coolant, although it is 'about' 50/50 water/coolant, this is why you get that coffee coloured oil, because of the coolant getting in to it, happened with an old V8 I had, and the oil in the water is probly just cause the oil is going back the other way, in to the cooling system.

ok removed the valley theres water and coolant everywhere so is that leading to the valley would i still have to remove the head ????

[BoNeZ-01]

This is where I start to get out of my depth, I haven't actually pulled apart a V6 yet.
Shouldn't need to remove the heads yet at this point, leave them till last, as they may not be the cause yet.
That coolant may have fallen in there while removing the intake manifold, as far as I know, some of the coolant flows through the intake manifold, and may still have been some left in there as you lifted it off.
Another member may need to correct me on this though..
But looking at my VS workshop manual, there should be two gaskets, one for each side, they sit between the manifold and intake side of the head.
There should also be two end seals, one at the front, and one at the back, they sit between the manifold and the engine block.
Inspect all these gaskets and seals carefully, to see if there is evidence of breaks, where coolant could have gotten through, and into the valley.
You will need new gaskets and end seals for when you put it back together.
Best thing I could say to you at this point is for you to get hold of a workshop manual for a VS V6, so that you have something with pics in it to refer to.

i definately would not remove the heads if it was running fine and the only problem is oily water as i have never seen a cracked v6 head the only time ive heard of it is when a mechannic is trying to part you with fist fulls of cash fit a new pair of inlet gaskets and all should be well if it was a head gasket it should have been running like a pig. the other cause ive seen for oil in water was a split auto cooler tube inside the radiator tank very messy.
