N62 4.4V8 water transfer pipe leak

[ian740i98]

Removed the water pump today and found out that it's not the water pump that is leaking:argh: the leak originates in the valley between the heads- the water pump sends the water through a pipe to the back of the block and this pipe has a seal on each end the front seal is the one which goes 90% of the time.

Stealer quote is in the region of R26000 to do the repair because they dismantle the whole top end including the heads. There are a few solutions to replacing the pipe on the web, but most of the replacement pipes from the States are in the region of $400. There is one other solution from Bimmerfix.com which involves fitting a stint into the front and sealing it. This kit comes in at $150 and does not involve taking the whole top off.

Any ideas out there?? Does anyone have an SA solution?

Crap, that's bad luck ..... It was a weak point with the N62 but to be fair its not exactly a common problem. The stint solution is a new one, looks worth a try.

If you are going to keep the car I would get hold of a good independant BMW mechanic (somebody experienced at working with valvetronic) and do the job properly ... might as well do timing chain and guides at the same time.

If you are going to get rid of the car, take the short cut and trade it

:thumbs:good advice, thanks. I've got a great Independant in Kya Sand and he has started opening it up. I'll update as soon as we see the inside.

Finally.... Got the job done. The kit took about 5 days to come from the states. It looks like nothing when you open it and see the pieces supplied - see their website ( wwww.biimmerfix.com), but it was successful! :joy:
The kit landed in SA cost R2500. Their is a step-by-step guide inside with photographs as per the website. If anyone has this problem, this is the way to go.
