Citroen/Peugeot 2.7 HDI.
Hi...
Does anyone know how much or the top end of 2.7 HDI would fit a TDV6?
I had a search through previous threads but couldn’t see anything.
Cheers

Depends on what you mean by top end..
Bare Heads: yes,
But: injectors, pump, etc. Depending on year and model...EU3 or EU4 + injectors may differ anyway (Same with LR and JAG)
But why the question? Heads also from LR are not difficult to find and not expensive...Best regards

Thanks for the reply Harold,
I have a 2007 D3 which has suffered cam belt failure. I have yet to strip it down but I have access to a 2.7 HDI from a Peugeot and was hoping that some of the damaged parts in the TDV6 could be swapped out for the HDI parts.
It will be easier I think when stripping both engines side by side, but wondered if this would be a worthwhile venture or would I be best finding a TDV6 with crank damage instead.
Cheers

2007 LR as in MY07 is a EU4 engine
2007 LR as first year of registration can be either MY06 (EU3) or MY07 (EU4)
so you have to know which one you have for the fuel parts...(pump,rail,injectors)
BUT ..........
since you have to remove these parts anyway to remove/replace the heads, it is not an issue, if you use your "old" LR parts... (swap them over)
the heads (alloy, camshafts (as far as i know) & valves) themselves are the same....
regarding whole engine as a lump:
gearbox mountingpoints from PSA versions on cranckcases differ.. to JAG/LR versions..
tip:
depending on the milage on your engine... and if the connectingrods are still 100%? after a piston/valve collision, big chance they are bent...
if you are here... why not swap the whole enigne for a far lower milage JAG engine?
saves you the headgaskets 2x and possible other work..
if you buy a MY 09 JAG engine, fuelparts, etc. are the same, "just swap the exhaustmanifolds and turbo + some sec belt parts.. easy to swap..Best regards

All very useful info. I suppose I’m just trying to be a cheap skate since I have the HDI sitting here. How do I tell which engine I have... EU3 or EU4?
I wasn’t aware of a change.
Cheers

yeah it could be worth getting the heads off the pug.
don't forget heads aren't that expensive second hand, (£100 each) so don't pay alot for the pug
... would I be best finding a TDV6 with crank damage instead.
not sure that would be a wise move.
so many other parts of the engine could have been damaged when the crank let go ... and some of that damage may not be obvious until engine is rebuilt and under working load again.
also ... as there appears to be no 100% certain answer as to why cranks fail, you might be rebuilding an engine using a component that caused the fail but is itself undamaged, just outside required spec..

Hi Dean... this was a timing belt failure so hoping crank is good. Hoping damage has stopped up top, and that the Conrods are ok. I know this is unlikely, but it was a low speed / revs failure.

one rev is enough... if a valve was at the wrong place at the wrong time..
stationary is still 600 tpm.... one minute is 60 seconds 8) still a lot of possible hits in a second
you can try... but if hoped wrong, it will cost extra money, since effort, buying a spare engine, 2 head gaskets, and maybe a lot more are worthless by then..
you are changing the heads.... so the valve's are allready bent i presume, why should the connecting rods be ok then? did you see how thin they are? they are cheap though... if the heads are comming of... buy 6 new one's, change them.. rather easy and fit new big-ends and then you go...Best regards

How do you tell an EU3 from an EU4?

There have been a number of cases where cambelt / tensioner mounting point have failed and DIYers have successfully repaired the engine by replacing the heads.
There is no point replacing the engine for this.
It's no fun removing the passenger head with the body on though. So don't think it will be easy.
But easier the cheaper than replacing the engine
Here is a recent example.
And note the link in the thread for more details

Thanks for that Pete, also read DiscoMikes post with interest.
How do you tell the difference between EU3 and EU4?

yes you can be lucky... but if not you have the work twice... and also the costs of (head)gaskets twice and.... conrods are not expensive.... if the heads are off, replacing conrods is a rather easy job... together with new/fresh big-end shells, gives it a real second life normally IMHO.
EU3/4 difference
have a search here on the forum... to identify the difference you need images... they are on the forum allready...
but a quick giveaway... this is typical EU3 (EU4 is different rail/divider/pump)
Best regards

nothing on the engine is "easy" with the engine in the chassis.
Certainly changing the conrods in the car is not "easy" and unnecessary.
Yeah the bottom end on these engines is far from great, but while they are working you may as well get some use out of them.
You need to draw the line at some point in terms of labour time and parts cost
