oops!!!

 

 

Today, i replaced the cam phasers, was a big extent of work.
The result was, that the noise is better, but not good enough.
The ticking in front of bank 1 is disappeared but now is at bank 2, i guess at the 7th or 8th cylinder a loud ticking, probably already before.
Furthermore the truck has no power, if i give "kick down", the truck will not accelerate enough.
I changed all spark plugs, at two of them (7th and 4th cylinder) the negative electrode was slightly broken an as i pulled with my finger at the electrode, it was abrupt. What can be the reason for that? Never seen before. They was CHAMPION spark plugs!!!
PLEASE TRY, TO FIND A SOLUTION WITH ME!!!!

 

I'm not sure I would replace these motors with anything other than Motorcraft plugs.

 

Just a question really, even running with LPG, if there were bad injectors wouldn't they still leak ?? Or is the fuel pump shut down when on LPG ?? Thinking out loud here I guess....

 

It could be the timing chain tensioners are shot..

 

if the truck is running with LPG, the fuel system is not in use, no pump, no injectors.
@ jethat:
i checked the tension of the chain, it was okay. and the noise is not more in the front (before replacement if phasers, it was)! the noise is only at driverside, 7th and 8th cylinder
