Title: 2.5 vm diesel water leak
Post by Si-H on Apr 11th, 2008, 3:01pm
Hi, got a problem. my radiator was punctured and lost all its water quite rapidly. I changed the rad, but I can now see a constant dribble of water from between the two cylinder heads on the fueling side of the engine(nearest the bulkhead). The water never had time to emulisfy the oil, hence no white emulsion. I've not done a compression test yet. (Will do at weekend)
With a constant dribble, should I expect a cracked head or a damaged gasket?
What else could cause a water leak in that area?  (Its not the header tank, I've checked it)
Anyone had a similar experience?
Any ballpark figures for repairs ?
Thanks in advance .Simon.

There is a coolant collector rail bolted across the top of the heads, but this is on the manifold side of the heads...

did the car overheat m8  if it did you will have a cracked head  if it did'nt overheat  then it will be the head gasket  i had a gasket leak  between 1 and 2  heads  and it was a fast leak as head 2 was cracked  as to doing the head gaskets it not a hard job  as i have  just replaced my head gaskets and it was pretty easy to do on the 2.5 td

Hi mate, no idea whether it overheated or not as my brothers mate had borrowed ther car ! Rarely get the whole truth from him !. As the hole in the rad was quite big, can assume it probably did overheat. So, should I expect a big bill ? Is it a garage job or at home ?

its a home job m8 easy  job not  hard one way to test  the heads to see if they are cracked  without paying to have them pressure tested is to change the gaskets and put the cooling side back together and fill it with water and watch for leaks when you take off you heads rember to look and see how many notches the gaskets have  ie  none one or two  will be on the gasket  you will need to get a gasket with the same number of notches to put back on  and m8   when you take the heads of you will find you have 4 gaskets  i replaced my 4 with a whole metal gasket   for a jeep cherokee and your inlet manifold and exhuast manifold gaskets  are all single   replace that with a whole metal inlet and exhaust gasket from vauhall for a fontera  2.5 tds you will need new head bolts  and get a litre of sae90 oil  coat the head bolts with this  when you put  the bolts back  i will give you a pm on how to do the job
