Amf lifters

[Roxanne]

Looking for advice ,
I have posted before about a collapsed amf lifter number 1 I ended up doing a complete rebuild now 18000 kms later and amf lifter 7 has collapsed what would cause AMD lifters to collapse .

The lifters are just a poor design. Your best bet is to eliminate the whole system, at least that's what we do here in the states. A buddy of mine just had this happen in his truck, so he swapped the cam, got new regular lifters and had it retuned. You really wont notice a decrease in fuel economy either.

There are saying no warranty as the supplier wont cover it as they dont know if it was installed properly the mechanic is saying it should be the supplier I have decided to issue a letter of demand for a refund and take the amf out
