Default replace head gaskets 407 hdi 2.7L

got lotsa trouble
car was blowing a lot of smoke so took it to local dealer
asked to give idea how much to fix (please do compression test)
after a week he said it had been overfilled with oil and had got into turbo, intercooler etc
cleaned all that up bill so far $2000
he put it all back together - oops low oil light warning have to investigate
maybe faulty switch
bad news - there was a blockage - we fixed it but when we started the car oil and coolant came out the exhaust
bad news we think youve got a blown head gasket
very expensive to fix -suggest a second hand motor
(obviously didnt do compression test as requested)

now me

ive lost confidence in the dealer
i can do mechanical repairs but this is my first peugeot
questions
how difficult to self repair
can i get a manual
where can i get parts
do i need to do diagnostics when finished
if so where can i buy diagnostic tools
i live in australia but happy to import

and

I'd say that's properly difficult, but I'm really not the person to ask.

You can get the dealer documentation through service box:
Peugeot Service Box
(you have to pay for it)
The parts diagrams are free to access though and might give you a better idea of what you're looking at.
(You have to register on the site. The registration assumes that you're an independent garage but just fill in the form and you get an account.)

I'd say that PP2k is a must. If after you've put it all back together you turn the key and it doesn't start then PP2k will tell you why. Get it off eBay. For example: http://www.ebay.com.au/itm/LEXIA3-PP...item3cdcc65333
(There may be cheaper ones shipped from China. Over here the going rate is about £70).
You'll need a Windows XP laptop to run it on. (Diagbox is a newer version and needs a relatively powerful laptop to run, and frankly I find PP2k better anyway.)

I would definetaly try to get a second opinion... sounds very strange the whole sequense of events to be honest.

Over filled with oil?
Then a blockage?
Then low on oil?

I have changed about 40 cars the last 5yrs and I have not heard or experienced a blockage that caused this kind of symptoms?

What is the mileage of the car?

P.S. The same engine is used on Jaguar S-Type, XJ, Landrover Discovery's and Range Rovers.
(Although on the Land Rover and Range Rover, runs on single turbo configuration instead of twin turbo)

Blown headgasket with less than 50.000miles on the clock?
If the headgasket was blown, did you see any residue of coolant in the engine oil? or any oil in the expansion tank?
Any sign of (mayonaise anywhere)?
Also was the car overheating especially on motorway runs? Did you have to top up coolant at any point?

I would have a look mostly for blown turbo seal or even a blown turbo.
What colour was the smoke?

Also was there any noises coming from the turbos? (ie loads of spooling, or high pitch noises etc, anything other than normal)


Sorry too many questions I know.

car was running perfectly up til then - no noises, plenty of power (a pleasure on the freeway)
never used a drop of coolant

I don't think anyone attempted the swap, (that I know of).
But the 3.0 is the natural evolvement of the 2.7.
I would think it would fit no problems.

Blown headgasket I would have assumed it would have leaked coolant in the oil and vice versa rather than in the exhaust system?
I would seriously check the turbos before I do go and research for engine and spend serious money.

I would take the car to another garage and check if what they say is true or a load of ....

Who has done the last service? was it you? or a garage?
If so how much oil did you put in?
