Pug 405 Diesel Cylinder heads...turbo and NA

A few years ago I had a Citroen BX 1.9 non turbo, the cylinder head cracked and I got a recon head from a scrap yard. I took the head to the mechanic doing the job and he told me it was a Peugeot turbo diesel head and it would fit. As far as I can remember he had to modify the thermostat housing, I don't remember the precise details as this was about 11 or 12 years ago but it did the job. I drove the car for another 3 years after that until I traded it for a Mondeo diesel. I hope this has been some help to you

I've crossposted this to alt.autos.peugeot as someone there may be able to shed some light.

IIRC the NA has a higher compression ratio compared to the TD, probably due to differences in the piston and/or head design.

Thanks all,

I think the CR will be down to the piston design as the head is flat.

Will go chk out peugeot section thanks Malc.

The early heads had square inlet ports, the later had oval. Provided that you match this, and of course get one with the right vacuum pump fitting, all should be OK. The turbo and non-turbo engines have a different compression ratio but this is acheived with different pistons. Don't know about the 1.8 head though. Valve sizes could be smaller. A word of warning though, make sure it comes with the camshaft bearing caps in place, as these are line bored, and not replaceable. I found this out the hard way. Failed an MOT on emissions as there was so much oil escaping from the bearings and it came out the breather. Then on the way home from the MOT the engine took off on the oil fumes. Amazing how much white smoke it produced, completely stopped the traffic. So I have a spare head now but it is not a lot of good.

Nice one, many thanks for that.
