Bugger! HG gone!
« on: 09 November 2009, 19:16:22 »
The thing is though, it wasn't showing any signs of such.

You may remember my old thread about the constant running hot snag. In my attempt to solve it I replaced the water pump, stat, rad, several switches, flushed the block etc etc yadda yadda.

At no point was there any evidence of impending HG failure. No mayo on the stick or around the oil filler cap, and no loss of water. Till today where I assume the car got fed up of a constant water temp of 95'c hence spat its dummy out.

Is there a thread on here for the 2.5TD HG replacement? Also, including parts and head skimming - ballpark figure wallet wise?

TD head cannot be skimmed.

95C is fine (on the gauge). How hot have you allowed it to go.


Its a pig of a job.  Ask JayW - he's still got one of my chain tensioners embedded in his forehead.

HG gasket with inlet and exhaust manifold gaskets (and a few others) is about £130 from memory.  Need to count the notches on your existing gasket, as they vary in thickness.

Head is BLOODY heavy.

Red light came on with a coolant warning on the LCD readout.

Looks like the car is dead then.

After all the trouble I went too what with changing the gearbox, chipping in addition to what resources I've thrown at it trying to fix the bastard thing. :(

The one in the temp gauge. Red light of death then?

It has come on once before though towing a full 3/4 trailer and then I was just as quick in shutting her off and coasting to a layby.

beemer heads have a weakness towards cracking when overheating :(  Won't know til you've ripped the head off.

Can these heads be skimmed? I dug up this thread here:

this is by no means gospel, but!! some can be skimmed as i understand it depends on the thickness and how much can be taken before you run into troub le with the preheat chambers,
so there may be hope , mind you there are loads of beemers and omega t,d being broken head shouldnt be to hard to find, but i would check very carefully before you condemn the gasket, could be a lot of things causing it including new water pump breaking again if you got a plastic one!!

The new water pump had a metal impeller. I suppose I can start stripping it down tomorrow.
