TU3 - oil in water & source for engine. - pug-boi
Hi guys,

I have recently decided to bring my old Peugeot 205 XS back to life after roughly 2 or 3 years of sitting around collecting dust (amonst other bits of green bits!!).

I know for a little while before it was parked up, it seemed to pass a very small amount of oil into the water and also a little bit of oil into the spark plugs on the 2nd and 3rd bore. I'm fairly certain that the head gasket will need changing but there are a few questions I have before I attempt this

1: Is there a chance that after a while the head may have warped slightly ( I have heard rumours this "may" happen). The engine (last time it was run) still goes like a rocket!!

2: With the engine having wet liners is it a complete pain to do?

and lastly (although i know this wont be the last question I post) 3: What other peugeot models use the TU3 engine that my XS runs as i may just try and source a good engine from somewhere?

Thanks in advance to any one that can help

Cheers

Hi Pug-boi. I used to own the same model 205, cracking little car with good turn of speed. I take it yours is carb model (twin choke I think) that gives about 80 to 85bhp. Short gearing between 3rd and 4th gave it really good pick up on motorways between 50 and 80 mph. Mine had 90k showing when I swapped it and burned a bit of oil which I think was from the valve stem oil seals. Should have done the job myself, head off and at the same time change cambelt. I'm not sure if these have wet liner engines, perhaps you can get away with it by not turning the engine or moving pitstons whilst head is off?
It's worth perserving, they don't rust so it's just the mechanicals to look after. I think the TU engine is used to this day in Citroens and Peugeots, with modifications. Certainly the 1.4 was used in the Saxo and 106. You may come across problems with them using fuel injection and different cylinder heads, plus I think the XS had a distributor? May be wrong on that from memory.
The TU engines are tough, I seem to remember in the 80's when it was launched with the Citroen AX they used the same bottom end from the petrol design for the diesel engine.

Hi Kingpin, your right it is the twin choke carbed version, absolutely cracking car. I didn't realise that the diesels used the same bottom end?? Would it be safe to assume that its just the block thats the same and not the pistons or crank, if it was it may well be worth rebuilding one with a view to dropping it straight in. If this is the case then it certainly means there is far more choice out there. I have been hunting around fro either another XS or AXGT that I can tear apart for parts but it doesnt seem like anyone wants to give them up for a cheap price (cant say as Im blame them really).

I was once informed that these engines did have wet liners and to avoid breaking them when removing the head you should twist the head rather then just lifting it straight off, I dont suppose your good self or anyone could confirm that for me. As cash is really tight I'm gonna do most of the work myself (gulp!!).

Many thanks
