16v Hdi diesel head gasket

Hello, I need to remove the cylinder head on a 16 valve Grand Picasso Diesel engine. The engine code is: RHW. Does anyone know of the head bolt torque/angle figures. Also, is there an online engine service manual for it anywhere?
Has anyone out there done this job before?
Is there any problem with replacing the combined inlet manifold/cam bearing assembly?
Thanks, Ian.

Hi..

Theres a much higher chance you having a problem getting the injectors out, to remove the inlet manifold, to get at the head bolts..

Injectors useualy refuse to move.. But WELL DONE if you have removed them!!

The 2.oi 16v HDi hasn't filtered down to many of us yet... the only 16v engine that has is the 2.2 in the First Gen C5.. which can cause good headaches...

Our best later HDi man is Chris - citroenmad

I'm not aware of any online manuals for the 307 but Haynes has released a 307 edition which may be of some use, providing it doesn't tell you to take it to a dealer for everything.

Torques are:

Stage 1: 20Nm
Stage 2: 60Nm
Stage 3: Slacken 360°
Stage 4: 60Nm
Stage 5: 220° ±5

The maximum bolt length is 134.5mm

307 TOby?

I thought he said C4 Grand Picasso.... Did the 307 get the 2.oi 16v lump?

My mind is wondering tonight. For some reason 307 was in my head.

Apologies.

They are the correct torques for the RHW engine though

Is this a 1.6 or 2.0 HDi Picasso?

This is the first report ive heard of with a later 16v HDi having a head gasket problem, very unusual, and there are many higher mileage examples of these around.

What mileage has this one done?

Haynes for the C5 covers this engine (well sort of - there were quite a few bits missing when we did the clutch on my mate's C5 2.0HDi 16V a couple of weeks ago). Not sure how much detail it goes into on the engine, but there's deffo a section on it!
