bent push rods !!

[defenderjack]

well this week hasnt excatly gone to plan ,

monday - turned up to job to find out gardner had done it for free at weekend !

Tuesday-flat tyre

wenesday-hands covered in annoying blackthorns and pissing hard rain all day

only to here a strange noise coming from chipper , misfired a couple of times then saw a little oil leak coming from around tube that covers pushrods got back to garage and striped down engine to find one broken pushrod and another bent ! joy oh joy .

so my question is apart from obviously rplacing neccesary parts is there anything more sinister that i should be looking for as to why this happened , to me it looks like the little cup on top of the rod that sits under the rocker arm has snapped off so im geussing the other rod has compensated which is why that is bent ?:confused1:the other cylinder seems fine . i should have taken some pictures really .

its a lombardini engine 9ld if any body has experience of these .

many thanks . oh and does anyone know how expensive pushrods are ?

Pushrods are usually dirt cheap and are generally the only things damaged when things go bad, like a transit 2.5di for instance, if the timing belt does go worst ways a full set of push rods is about £50, they're hollow so bend saving the rest of the valve train. Dunno where or how much for your chipper though unfortunatley, you could have a go at straightening them?

Cambelt?

 

so the timming could be out then ?

[twistedhicap]

im thinking that that engine would be a gear timed unit ! very few of those will be cambelts ! check rocker shafts and it may have bent the valves if its come down hard ont he pistons might be worth poping the head/ heads off for the cost of a gasket it may be peace of mind !

[tommer9]

I mean its more likely to have either snapped or lost a tooth or a few teeth. That is almost exclusively what causes valve stems or push rods to be bent.
