help needed if possible please, i know it's hard to diagnose any engine noise without hearing it but my 05 animal developed a slight engine thump last week so pulled over and got it recovered to a friends garage incase i caused more damage, i had this last year but a hell of a lot louder and a lot of vibrating which turned out to be a bottom end rebuild. this time the garage looked and said the timing belt was loose so they've tightened it up but its apparently still making the noise, i've been having some fueling issues recently so my thoughts were an injector but they're saying it wont be that and they think it will be a cracked block..

any thoughts please>?

thanks in advance chris

Bump

A block cracking is a pretty rare event. Your compression would be very low and not sure how they could diagnose that.If the belt was loose it may have slipped a tooth on pump timing which would muck up your injector squirt (technical term )

Well you saying that about injector squirt. I've been having fueling problems of late almost like it's running low on fuel so I've asked them to whip out the injectors as have them checked

If the belt has jumped a tooth on the pump cog then your fuel timing will be out and basically the pump will be squirting your injectors just too late/early and make it run crappy, so if they said the belt was slack i would make sure that the timing is correct. Then i would want to know why the belt was slack, has it stretched ? is there a faulty tensioner etc,before you start testing injectors.

they still think its cracked block or crank..

quick update... injectors tested, 2 completely stuck open so 4 new ones ordered. the garage still adamant that wont be the problem but fingers crossed its all it will be

Thanks mate. Me too. Hoping not the crank. Had a new one with the rebuild 20000 miles ago

was it using alot of fuel Chris ???

@akc signs

A bit more than usual I guess. It's been having a fueling problem for a while. Like holding back and missing

mine feels like that aswell, I wonder if the fecked fuel has damaged the injectors aswell. mmmm food for thought.

I've ordered 4 brand new ones. Going in tomorrow so will see.

Might try that bez. Then send mine for recon.

Chris. Where did you order them from. Milners do them for £48 inc vat each.

I don't know Alan. The garage has ordered them

Prob from mitsi then an i bet they are expensive.

just found out the diesel specialist has refurbished them so not new ones, still got the engine noise so they are checking the crank tomorrow

me too mate, piss me off it is is. 25000 miles on a recon bottom end

Think I'm going to overhaul the rule system on mine in the hols this year.

ask the garage if they have a stethoscope to listen to different parts of the engine when its running, it should give them an idea where the knocking is coming from, to just start guessing its a dual mass flywheel when these trucks dont have them tells me they are just guessing now. could end up costing you money.

I agree Alan.

its gone to the engine builders who did the recon to see whats wrong, they're taking the engine out

Under warranty ???
