Hello
My father in law has a c15 romahome camper with a 1.7d engine which requires a replacement head. This is proving difficult to source and we were wondering whether there is commonallity with the 1.9d head? As these are much more commonly available. Option 2 is a complete 1.9d transplant.
Cheers Gethin

Re: XUD engine cylinder head commonality?
The LATER 1.9d heads with the upper plastic Rocker cover fitted from around W X or Y reg wont DO.. Known as the DW8, even though they are still a Roatry Pump injection system and a 3 bearing Cam shaft machined directly into the head the oilways are slightly different between head and XUD block.
I beleve a TD head will do the same job, as they were idendical to the Non Turbo heads, prehaps slightly better material to cope with the turbo boost pressure and a better head gasket.
The 1.9d N/a heads will be perfect for the job, they used the same valves etc, so you should have no problems.. N/a engines from 406's, EARLY 406's, 205's, 309's (if you can find one) and EARLY 306's and ZX's, should all do the job nicely.

Re: XUD engine cylinder head commonality?
Paul, I'd tend to agree, XUD heads are pretty much interchangeable but TD heads do have better valve material I believe.
One thing is that a turbo camshaft will not be happy in an NA engine so if you do swap for a turbo head swap the cam over too. The turbo cams are a good bit 'tamer'....
When swapping cams do check the valve clearances carefully and re-shim if necessary...

Re: XUD engine cylinder head commonality?
the N/A and TD have diferent shaped inlet ports,
cant remember which way but one way the manifold does not cover the inlet ports of the head fully,
the engine will still run more or less ok but will always sound a bit like its got no air filter on,
if you send me your chassis/VIN No. i will check all families on service citroen,
this will show all citroen models with the same head,
the other thing to try is give these people a call as they are cit/pug dismantlers

Re: XUD engine cylinder head commonality?
I think Malcolm you will find that Early xud N/a heads have the square ports by early i mean the 1983 to around 1991 heads are square then all later heads are oval .. that certainly how the bx n/a was originally 65 bhp then by 1992 the bhp was upped again to 71bhp.. i believe this to be oval port head on later n/a engines.. and so no issues with inlet.. these heads are identified by the inlet intake location from the air filter in the middle and not on the side as early early ones were...

wouldn't fitting a head with better valves be beneficially better then a lower spec?? i would..

Re: XUD engine cylinder head commonality?
Didn't buy it. Father in law wants to get a new head now as it is the easier option than engine transplant.
Re: XUD engine cylinder head commonality?
GSF do new heads complete with valves and cam for around £500 quid ready to bolt on
