Hi all I need some help!

Looking at the engine with bonnet up.

I have steam rising from down by the right side turbo!

 

This means a water leak! It only happens from cold after the engine is warm (5 mins) then only for about a minute then stops!

 

I am not losing lots of water. But to get to the water pipes! Is this an engine out job!

Merry xmas to all, leak or not my Z is going out on xmas day!

Oh forgot to ask doh!

Is the pipe a metal one or rubber

Arthurl

There's a few pipes down there but sounds like the coolant feed to the turbo. Are you sure its coolant and not just rain thats run down the engine bay???

 

The turbo coolant pipes are a mixture of metal and rubber - fingers crossed its not the metal ones as these are a complete PITA - not that the rubber ones aren't though ;)

Just to confirm what Andy said. Also if you can purchase a pair of long nosed, 45 degree bent pliers, there about a foot long! its makes the job alot easier. 1 hose will take at least a couple of hours to do!! Luvly Nissans arnt they.

If it IS the pipe, don't bother pulling and swearing at it - just get a stanley knife blade and slice along its length then peel it off - the new hose will also go on a lot easier with a bit of slicone grease smeared just inside the end ;) (this tip courtesy of Jonnyz32 :D)

Hi

Thanx for the info. It is definately coolant.

The reason I asked about the pipes was that, when the engine gets warm then the steam stops! Like the heat would expand metal.

If it was a rubber pipe I was thinking it would continue to leak or is that rubbish?

Hi all!

My local mechanics have located the problem to the metal turbo water pipe!

They fone nissan for some help reguarding pipe ect!

Nissans reply to them is- the car new cost £40k & the engine is complicated Dont touch it! FFS!

 

So if it is the metal water pipe into the turbo, they have put it on compression & it does leaks!

1 What connection has it got? A compression joint connection?

2 how long is this pipe & where the f--k does it go from the turbo? To where?

If it is a PITA that is not a problem. My mechanics will sort it, on my go ahead. They are concerned of messing my car up!

Hi again!

With all the diagrams, pictures & my old engine, I think & the mechancs agree, that the pipe involved is indeed the turbo feed pipe at the back of the engine & bulkhead as AndyDuff said!

So I have told the mechs they can get to it if they remove the battery. God knows what Nissan told them!!

My only other question is, the rubber pipe to be changed is held in place by these self sprung clips!

How the f--k do you compress and hold them open? then release them!

Is this the use of those foot long 90 degree sort of pliers mentioned before?

Water, Water everywhere!(not that bad, yet!)

Arthur

The clips are fairly simple - just squeeze them with the long pliers, then slide them off the end of the rubber pipe - just watch where they fall when pipe comes off ;) It shouldn't take them that long I wouldn't have thought. Chances are they'll need to chop and weld a spanner to get to the banjo fittings on the side of the turbo where the pipe feeds in but that should be about it. Heat shields on the turbo will be fun too as the bolts will probably shear - unfortunately the heat shields cover the water feed but they *might* be able to work around it if they have small hands....

 

HTH
