May have a problem, td5 2001 es auto, had head skimmed and gasket done 5 months ago due to loss of water and overheat also had injecters done, now goes like a bomb and pulls 1800kg caravan no worries, Last night and this morning had radiater light stay on for a few seconds longer than normal despite being ok with water level. Also noticed temp gauge going passed the normal half way point at which point fans come on, this has happened twice. Now cakking myself as I go away towing caravan in two weeks. any ideas??
It`s in for mot today and I have asked local garage to have a look over it, they say possible air lock or sludge in radiater restricting flow and cooling.

Any points much appreciated, Thing is it towed last weekend no trouble at all.
 
Hate to be the bearer of bad news but if they skimmed your head, it's now scrap.

From the manual read :-

Cylinder heads must not be refaced.
Replace the head assembly if warping
exceeds the limit.

Who did the repair? Surely they should be resposible for a replacement.

Hi thanks for that, local independant Landrover specialist would you believe they should of known surely. I`m sure they said they had it skimmed, had no problems in the last 5 months, I have now realised that the warning light is water in the diesel and not low water in system as i first thought as per my other thread. thanks anyway

What LR say and main dealers do is a different thing to what goes on in the outside world.There is no problem in skimming TD5 heads, the main thing engine shops have to do is to maintain the distance of valve head to head face.It is done on a daily basis with excellent results.Remember LR said not to skim TDI heads too - how many of those have been done over the years,I have even Tig welded corroded ones and hand scraped them flat again when I couldnt get them skimmed quickly enough.
What invoice would you rather pay,for a skim or a new head ? - the cost of a head is very good at focusing peoples minds.
 
Hi thanks for that, as my other thread says it turns out radiater light its not but exssessive water in diesel light, (sensor on filter)

Not really,it was only small areas of weld - probably would have taken longer to drive to the engine shop and back.Did a head off a VW Caddy pickup - had burnt a groove between cyls 2 and 3.Once I had finished and cleaned the whole face up with a quick rub on a flat surface with fine paper and WD40 it looked like new.;)
 
I remember reading many moons ago that the VW diesel heads couldn't be skimmed and had some done twice with no problems . Same with Tdi - have had a few skimmed and going fine thousands of miles later . I was told by an engineering works that they sometimes in extreme cases take a skim of the valve stem to maintain the clearance between valve and head .
Not good practice I know but have saved people the cost of a new head on an old but otherwise sound vehicle .
As eightinavee says the real world is a long way from what the main dlrs etc would have us believe .
 
What you have to be careful of with Tdi heads is not only the valve head to face distance (as above), but also the protrusion of the injectors. If you reface the block / skim the head too much eventually the injectors hit the pistons. Although I must say that in the engines I have seen where this has happened it doesn't seem to have done any real harm.

And I agree - according to LR you can't do anything much. We also grind TD5 cranks now - also a no-no. We should compile a list of things that are not allowed but done in the real world.
 
The list would be an excellent idea .
Then when someone has a problem it could be looked up and quickly find out how others dealt with it - because what's possible ( in the real world )is often very far removed from what manufacturers etc would have us believe .
And when it comes to skimming a head or grinding a shaft etc. there is usually someone out there who has tried it and we can learn from their success - or failure .
