Peugeot/Citroen TU Head Gasket Replacement

Replacing the head gasket on a Peugeot or Citroen TU 8 valve engine. In this instance a TU3JP 1.4 fitted to a Saxo 1.4 Automatic. The process should be almost identical for other capacities of the TU engines as fitted to the AX, 106, Saxo, 306, Xsara and a range of other PSA cars.
The problem I noticed with this car was when servicing it I checked the radiator and seen that there was oily sludge in it. Being an automatic there is a possibility that the transmission cooler was leaking however this was not the case and the car needed a head gasket replacement.
TU engines can give trouble in this area, the one upside however is that they are an easy engine to work on, in the saxo there is great access to all of the parts and it is still relatively easy to get spares. Although i have found with the saxo some parts are now getting harder to find as the car gets older and less common on the roads.
The timing belt video I did a couple of years back on the 106 1.1 TU:
• Peugeot 106 Timing Bel...
This shows the replacement of the timing belt and subsequent bleeding of the cooling system. It was almost an identical procedure to this saxo except for the fact that the saxo had a manually adjustable timing belt tensioner, the 106 had a more convenient spring loaded one. Also I realised since doing the 106 timing belt that the engine mount does not need to come off, although it does make access better it is just not necessary.
It is possible to just replace the head gasket and hope it solves the problem, however since this car is one my grandparents are going to drive (as it is an automatic) I wanted to leave it reliable so the head was skimmed, the radiator replaced, the coolant flushed, most things done except for replacing the timing belt and water pump as these were replaced within the past 2 years.
The costs were:
- Head gasket kit; included new head bolts, and gaskets/seals for the top end of the engine - £40
- Head skim - £40
- Coolant flush - £20
- Thermostat - £8
- New Radiator - £50
- New Coolant - £10
The engine was also serviced with new filters, an oil flush, oil, new plugs and while the head was off a perished boot on the steering rack was replaced.
This was my first time doing a head gasket on a TU engine so any constructive suggestions on what should be done differently are welcome.
