the water should stay the same colour, are you getting smoke out the exhuast (white) or is the coolant bottle pressurising

Constant cold air coming though heaters. It'll drink coolant. Mayo under cap (although take for a long run and should go away). Loss of power to an extent. If in doubt take to a garage to get a compression test.
The smoke will just be the diesel getting burnt off. And possibly loss of power will be coming from the diesel.

The head gasket? I'm sure you've been flamed for saying HG replacement is cheap before.

Wouldn't hold out much hope of it lasting long though.
If he's having trouble with compression a skim would be wise and that alone would cost around £30.
A good HG swap with all bases covered would be around £100 in parts.

why wouldnt you hold much hope for it? i done one on an engine for £30 2 years ago, the engine has been in 2 different cars since then with nothing but a general service since, and i know for a fact nothing else has been done as i see the chap who has the engine every day. you dont need to change water pump/cambelt/head bolts etc or get the head skimed unless its absouloutley nescesarry. i have done a couple more since that one aswell and only changed H/G and they to are fine, everyone worries to much about things like this. If it aint broke dont fix it.

I did a head gasket for £12. Literally changed the gasket, not even the bolts. Held on for thousands of miles and that wasn't the reason I got rid of my car, engine was still working.

Well it's up to you if you want to be a cheap arse but any reputable engine builder will suggest changing the cambelt unless history of it is known. If the head bolts have been on for a long period, they should be changed as they're stretch bolts. £12-30 for a head gasket change is a bodge.

LOL why is it a bodge? just because i havent changed cambelt/water pump etc dosent make it a bodge, if you want to go spending hundreds on a H/G change then fair enough but just because people say to change this and that dosent mean they have to be changed. like i said and so has Root, we have both done head gaskets for £30 or under, both engines are still going strong today, if we would have changed water pump etc at the same time the engine would still be the same as it is now, so i fail to see how it is a "bodge" as you say.

It's not a bodge, it's low cost basic engine rebuild + HG obviously.
It's all down to the preference of the persons car, and how much money he/she is willing to put in to it fixing.

Maybe bodge is the wrong word. It isn't the right way to do a HG change. If bolts have only been on a few thousand miles the yes they'll be reusable. If they're old bolts they should be changed as they are 'stretch' bolts. as I said earlier if somebody is having a problem with compression then a head skim should be done. You can do a straight HG swap on the cheap but to me that is a bodge and asking for trouble, especially on a performance engine. If you guys just slap a HG on a car then carry on. when i work on a car I make sure as best I can the repair will last, not keep running by good fortune. Especially when working on a customers car.

There's no such thing as a low cost engine rebuild. These things cost money. If someone is having issues telling them to just stick a HG on is poor advice. These guys haven't seen the engine in question. What if the head is warped/cracked/porous. The OP would then have spent the best part of a day for nothing as the new gasket will have been a waste of time!

totally agree with you when its a customers car and they are willing to pay to have all the work done, but when its someone that wants to spend now more than £100 (including labour) then you do what they want, as i have said iv changed only H/G a few times for people and one of my engines, the one of them being a 180bhp RST, ye not masive amounts of power but its still going strong to this day a year ish on.

it's not being a cheap 'arse', it's doing a cheap repair. Obviously useful if you didn't buy the car for much money and don't intend on keeping. Just running into the ground.

It's hardly a cheap repair if you replace something that didn't need doing.
This is the second time i've seen you just replace the HG when someone has a an issue which doesn't sound like HG failure.
The guy's car is smoking which is possibly the diesel and the brown water will be rust from previous owners not using antifreeze.
A quick question for you.
When you stick your £12 HG on it's obvious you re-use head bolts, cam belt and waterpump. But what about the exhaust gaskets and coolant? Do you catch it in a bucket and re-use that?

I did not diagnose his problem, I said it is possible to do a cheap fix, just replacing a gasket and nothing else.
end.
And I didn't take the exhaust off there, I took it off further down the pipe because the bolts were seized on
