[beppe.c]

hi!I ? arrived in the workshop a alfa 156 mtj16v that broke the timing belt,after having dismantled the valve cover I noticed that 15 out of the 16 rocker arms were broken.I get the rocker arms,arrivatomi I minister to the assembly.after reassembling everything the car starts perfectly,smooth idle,performance identity before the break,only thing ? exit out ? a beat of puntaria that you feel that only on one cylinder*****and do you check which or which the tappet ? gone?
ps I also replaced the oil and oil filter before starting the machine after cleaning.
I hope I don't change them all, and 16 for one rumoraccio.

X control which or which the tappet ? went just to see the one and molleggia..
the pane to the need or not to replace all the 16 it seems to me you sell even 8x time I would not like to be wrong..

Also replaced the hydraulic lifters, all

[IlCurioso]

The punetrie idrailiche before re-installation does not need to download them from the oil? Cos? you can see if there? some of them stuck...

the exact procedure in these cases, and the replacement of all the lifters, because they have suffered a crushing affect the operation, as to be changed all the rocker arms, even those that do not are broken.

The beat may also be caused by a valve, bent... no ? said that in addition to the noise should give you other symptoms, type of smoke or loss of performance, having those valves with the stem very up and even though bent manage to close anyway in their homes.

[ugoboss]

if it is bent, I do not believe that close, and if you are not close enough to measure the compression that you can see it immediately.

Considering what has been said until now, the causes of the noise if you're sure both of the tappet, everything changes, and controls the range

I agree with hugo boss. To me, and understood, and x to go on the safe side I changed all 16 lifters full of hammers, x valves are difficult to bend, another thing you have to check if you have loosened the two bolts of the axis to games hello to soon
