Timing Issue On 2006 C5 1.6 Hdi

[xsaraiihdi]

Hello All

 

Some help needed please I have a 2006 C5 VTX+ 1.6 HDI it had a problem with the exhaust camshaft (missing tooth) this cause the chain to stretch and wore a 4mm grove in the cam ladder, So purchased a good second user one of EBAY abd fitted a new chain and tensioner. Timed up according to my Haynes manual mark on the cams at 10 oclock and 2 oclock  when rotated 40 times the mark come back to their original position. The Cam followers where then compressed in a small vice to close them up and the cam ladder refitted.

 

A new water pump has been fitted along with a new cambelt and tensioner. This has been timed up with crankshaft timing mark at 12 oclock, Fuel pump timing mark at 5 oclock and camshaft timing mark at 11 oclock using the correct timing pins. The problem I am having is that their seems to be no compression or very little. Has anyone else had this problem.

 

Thank You

If by cam followers you mean hydraulic tappets, then possibly by compressing them the inlet valves are not opening to let in any air to the cylinders to be compressed. I did not notice anything in the Haynes manual about having to compress the tappets before fitting them.

yes had a few 1.6 that wont start due to lack of compression and belive it or not everytime it was down to the egr valve. if the valve goes theres no compression. hard to belive but true

Thank you for the replies. Still investigating the problem but believe it may be down to the replacement cam carrier. The car had a new (Heller) EGR valve fitted just after I purchased it due to running problems had a cheap Ebay replacement one on it found receipt in the boot. Will keep you posted.

Good news car now running and sounding better than ever and very responsive. Just one small problem on the cat and dpf. It would appear to have been taken apart before I purchased the car and who ever reassembled it failed to fit the seals between the to halves. So will be ordering them next week.

Did you need to do anything to get the compression back ?

 

If you remove the dpf to fit the joint you may want to clean it, some people water jet them to remove the ash and there may be other ways to clean them.

To get the compression back I used a fully charged battery and my booster charger turned it over on the key for about 20 seconds each time and it took about 30 attempts then fired up. As for cleaning the cat and dpf I closed off the (small inlet to the turbo) on the cat and filled it up with Coca Cola. I also did the same on the DPF and left them for about 18 hours. I then jet washed both Items and dried them with a airline. Just need to fit the new seal set when it arrives and a new clamp on the DPF to front pipe to cure a blow on thier.

 

I then cleared al the fault code with my Lexia and ran a global diagnostics No faults codes except one for the steering angle sensor this has been thier since I purchased the car so new Comms 2000 unit to cure this fault.
