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:

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.

Nice job – good to see attention to detail such as removing oil or debris from the cylinder head bolt holes.
Superb work very impressive , good video skills and layout of each step
How did you clean pistons 2 and 3 as you shouldn't turn the engine over without placing a clamp over the liners to stop them moving up on the piston upstroke when they risk breaking their seal at the bottom letting in water? I make a clamp using the old cylinder head bolts and a bar across the tops of the liners so I can turn engine brings pistons 2 and 3 to the top while the liners cannot move. Once at the top the pistons are much easier to clean up and also stops crud getting in the bores. I am a bit worried though as the tops of the cylinder liners in contact with the head gasket on my car are a bit pitted from corrosion in places. Engine has only done 60k miles.
Hey so I would like to know what can I do if my peugeot 106 only runs on 3 cylinders instead of 4? One of them stop working after it gets heated up.
Excellent video. You showed everything and didn't get in the way of the camera. The viewer saw everything and it gives me great confidence in doing it myself.
do you always wear your shirts inside out? haha
Excellent video of a very professional head gasket job…… my only constructive suggestions would be…… you could oil up the pistons and rings/ cylinder bores BEFORE you place the head on the block, and you could put the new spark plugs in straight away, this helps prevent anything falling into the cylinders if you drop one of those fiddly manifold nuts or anything???
very educational
Oh and btw, do you know where that vacuum pipe / hose close at 4:02 is for? In my car it has been partially removed and cut off: the one hand of the hose where it comes from close to the left headlight sits just open, and at the place where it should be plugged in close to the throttle valve is a torx plug to close it off..
I'm not sure about this engine layout; a 2000 1.4 Tu3 should already have a coilpack instead of the spark plug cable setup, and the valve cover also from an earlier year. Might have had its engine swapped for an older one? My Peugeot 106 1.4 Sport seems to have head gasket problems too, found some smudge in the coolant (not so much as this Saxo, only a few dots) and it is leaking some oil close to the timing belt (people say these are signs of head gasket leak) so I'm ordering the parts as we speak (love how cheap they are for a 106 1.4) and a friend who is mechanic will do the job for a reduced rate. A regular car garage would ask around 500 for the job, and the car is not really worth such an investment. Also doing the timing belt at the same time, because i dont know the mileage on the current belt, and the mileage on the clock might be off because for some reason it resets itself to 190,000 kms after reaching 200,000 (so who knows how many times it already did that..)
Very professional job. It is difficult to do this job in service points ,with the right way, in Greece. Congratulations. I am a peugeot 106 1.1 owner with 440.000km without head gasket replacement until today….
why did u put oil in sparkplugs hole?
The unknown part is suppressor.
Good to see, but what a job to do no wonder so many in the scrap yards in the UK
your t-shirt is inside out.good vid
Good job men in french jolie travail c quoi comme voiture ? Merci thank
Like!!! Thank you very much. I enjoyed your videos a lot.
its good job awesome
Thanks bro. Nice video you are perfect
Amazing video. Thanks a lot! Nice trick to pull the head.
mark 1 engine with injectors think some has been there before or am I missing something
Can you give to me please the Nm of the nuts of the cover? Thanks
Nice video !! But, i think you have to unsrew the head bolts in reverse order ( in order to reduce the chance of warping the head ) . First, you have to unscrew the bolt No 10 ..next No 9 etc.. until No 1.
Wow, you're so great!! 😀
How many miles does the head-gasket need to be replaced?
It's very common issue on these engines. You're gonna do this again after 2 years :).
Do you would recommand to plan the head at 0,1-0,2 mm for better compression?
I mean you will have to work on it anyway
