Dirty Diesel question...

[Invalid Boy]

I've been running my 406 happily on a mix of SVO and dead dinosaur. XUD9te

Yesterday the engine check light came on. I was amazed, I didn't think they were that sophisticated. Then a noise developed. At low revs the light was on, at mid revs the light went off. I didn't want to test high revs!
But the car felt underpowered, especially when setting off in first. It stalled every now and again as I tried to coax it to a safe place to park and check it over. Restarting was difficult, but it would fire up after plenty cranking. It cut out at a roundabout and would not restart.

As I was waiting to be recovered, I lifted the lid and the drive belt had shredded, leaving just a thin strip. The cambelt cover was cracked too. I have pontificated that perhaps the shreds entered the cambelt housing and caused it to jump a tooth or two.

Bought a new belt and tensioner and the drive belt. As I've been stripping the engine and trying to set up the timing lock kit I can't get the prong to mate with the flywheel, despite the cam and pump prongs lining up.

This is where the question comes...

How many cam revolutions per crank revolution? Is it possible to line up the camshaft and have the crankshaft out 180 degrees?

I ask because as I turn the engine at the crank spocket nut I can only see the cam sprocket. I marked the cam wheel with tippex, marked the flywheel in the viewing window with tippex too. I rotated it until the cam sprocket was alinged again (surely 180 deg of a 360 deg cycle) and tried to locate the flywheel prong. It wouldn't go in and there in the viewing window was that tippex mark again!

I've had a couple of pops at it with the same outcome. Tired and cold I packed in.



Hmm just had a thought... why not tippex the crank pulley?

I'm an oaf...

The crank goes round twice for every cam revolution.

I have a rod bent to the right shape to get up behind the starter to locate & lock the flywheel for doing cambelt jobs on Puegeot XUD engines. With it in you should be able to fit M8 bolts though holes in the cam & pump pullies & thread them into the head & pump bracket.
A month back I did the cambelt on my Dad's 306td & I forgot the locating rod at work for the job, I removed the tin sheild covering the flywheel at the bottom of the bellhousing & marked the flyweel against the bellhousing with a blob of paint. As it's working on a larger diameter than the belt sprocket it's more accurate, the mark moves a long way for a slight crank rotation & it's abovious if you move the crank. I've got boxes of random bolts so the 2 M8s for the other pullies were not a problem.

You are really wanting to check the timing betweeen the crank, cam & pump so you really need to fit the flywheel locting pin up behind the starter & see where the other 2 pullies line up.
If you've got the pin it'll just be a case of slowly turning the flywheel til it pops in, but I've seen me miss it going more than a full revolution of the crank before I get it in, I've rounded the end of the one I use to help it locate.
With the pin in the flywheel the crank & cam pullies should either line up & you can fit the M8 bolts or be 180deg out & you'll need to turn the crank a full turn to get them to line up. If they line up anywhere else then you need to start crossing your fingers that the valves are straight!

Ralph, Kev, thanks for the replies.

I made up my own timing setting kit including a flywheel locking tool (13mm open ended spanner cut and welded to a pinto distributor locating locking tab).

I was experiencing a brainstorm about the cycle though.

I got on with it today, all fitted up and correctly timed it fired up!

She idles fine and drives decently. However, power is down and there is a whistling noise on acceleration (or what should be acceleration).

Could I have disturbed some of the turbo pipe work? I had to manipulate the two black plastic pipes that cross over the engine and disappear down behind the cam sprocket.

At higher revs it's as flat as a kipper's dick.

[hillbillyracer]

It sounds like either an intercooler pipe has burst or come off, or possibly the small boost signal pipe going to the injection pump. With the whistling noise I'd think an intercooler pipe more likely. With it being french it'll be the most inaccessable one!
Any chance the flapping belt has holed one? I'm not familier with the layout of boost pipes on a 406 but it's not a top mout intercooler like a 306 is it?
Get someone to rev it up from idle while you listen under the bonnet for the source of the whistle.

Good to here it's not done any internal damage though!

[Invalid Boy]

That's exactly what I was thinking. The two black plastic pipes go to and from the intercooler...

...lets just hope I've not fully tightened a jubilee clip!


I was leaning into the bay and pushing the throttle lever listening for the whistle but nothing in the bay seemed to be leaking. I wonder if I've fractured a plastic pipe whilst manipulating them.

Too right, I've got forearms like an American Emo Teenager tonight!

[hillbillyracer]

I've had boost pipes blow off due to the clip not being tight enough, the Fiat Scudo which had the XUD engine was a bugger for it. You'd be pulling up some hill laughing at slow Transits & there'd be a whoosh it'd fall on it's arse, no go at all!

Had a similar experience in a Multipla, full of adults with autism who wanted to get to the destination yesterday. I was booting it then pop and no power. They got home eleven minutes late and kicked fun out of the night staff!

...then this morning it won't start. What gives?

I didn't swap the fuel filter because only Halfords was open and the Durham branch didn't have one in stock. Off to Gateshead this morning to buy one.

Fingers crossed that its a blockage!

..so then, a Northern Ladd?

I have been havinn a nightmare with failing Dipped Bulbs... from the North Shields/Silverlink Halfrauds.....

[Invalid Boy]

Aye! Chester-le-street.

The Team Valley Halfords is actually a proper factors! Phil there knows everything.

Have you got a trade card? Bulbs are pennies!!!

[tooSavvy]

Halfrauds have lightened (pun?..deffo!) my beer fund by 5,000 pennies, at the last count (I think the 'o' doesn't belong in there)

I have had repeated replacements.... and now give up [actually, they gave me up >> insisting I see an AutoLeccy] & so I bought RING XenonMax +100%, from MotorWorld........

Pah!!!

[hillbillyracer]

Possibly an air leak that did'nt affect the running but has let the fuel drain away from the pump & filter overnight?

The filter housing was brimmed. I replaced the filter with new and primed it up again. No joy.

Knackered IP? Blocked injectors? I've a spare bosch pump and injectors on the shelf.

The whistling was down to an intercooler pipe that I think I forgot to re-attach! It was dark...
