....

iirc, some of his workmanship was 'questionable' so a possibility.
.....

I know that Mark had some personal problems which led to him leaving the forum, but that's the first I've ever heard of any of his work being 'questionable'  :-? :-? :-?

[Jimbob]

if im on the right track...

I can think of several issues coming to light...
Wrong heads on an engine - old heads on new engine, with therfore wrong oilways.

coilpacks sat loose on plugs.

apologies to MM if I am wide of the mark on this, but theres something niggling away at me.

Masters - can you post up that pic you texted me - blown up better than I can on phone, wonder if it might show something either to me, or other keen eyed members.

I guess if not hoses/hbv, that leaves core plug.  Wonder if one of the mobile mechanics here has a spare 3.0l head....

If needs be, got both sides. Postage wouldn`t be much either

From what I have found when core plugs have popped the water pours out as fast as you pour it in without even starting the car

[Darth Loo-knee]

Think I would PM Guy and ask him what was done mate being honest. He will tell you mate.
I would pressurize the system whilst you have a few parts off, if its leaking like you say should not take long to find it.

mine was a slow leak....

very slow when hot  - 100 odd miles between warnings
not so slow when cold - 10 odd miles between warnings

As said, pressurize the system. Easiest way is to get someone to seal their mouth around the water bottle opening and blow, it doesn't take much pressure for the leak to spout, while you look for the leek. Could also fit a pushbike valve into a motorbike brake master cylinder cap which will fit, or another coolant cap, or drill a valve into yours and buy a new cap later....then pump it up with a push bike pump.

If the plenum is off though, you'll need to clamp or block the small coolant hoses to throttle body and what ever else is disconnected for it to work.

The OP mentioned that water was 'Pouring Out'.. when I have seen core plugs actually out water Pours Out as fast as you can get it in even without the car running....
We are all guessing, in which case pressurizing is the answer to find the leak... Although if a core plug is actually out pressure will not be possible..

[Jimbob]

aye, never heard of another like mine.


What is it with 98, 3.0, MV6's?  :-/

It is rather strange  :-/
I would ask Guy to see if he can shed some light on what was actually done to the car.. 

[TheDaddy]

Ok - Many thanks for the advice.
I have had another look this morning and just cannot see this bloomin leak. :-/
Very frustrated - so need to walk away.

Direction :-> has anyone got a picture of exactley where  the core plug is, so I can check on this?

Pictures taken before.

[Darth Loo-knee]

I dont want to come across rude here but a few people have mentioned pressurizing your cars water system. This will show up water leaks. As soon as you have some info post it as r
there we be people able to help you. As it is, its just guess work...

Hope that helps

[RobG]

Two plugs behind dispack bracket, but pressure test first as advised

[TheDaddy]

Thanks for the advice.
I will take the top off again and look at pressure testing the system to find out where the problem is.
What you have to understand though, unlike top notch, very experienced mig specialists like yourselves, I am a novice with very little experience and parts available, so what may be a simple job for you is usually a bigger job for me, though I am trying my best to take the advice and progress.

Not sure if just blowing into the coolant bottle will create enough pressure to identify the fault, but will certainly try and give it a go, but also trying to find a valve to put into my cap.

Will let you know any further findings on this.

Cheers
