i have built a 2.0l zetec up from scratch.
its got a rattle which increases when you let off the throttle.
gets quieter when on the gas and sounts like a tappet tapping away.
the thing is the tappets are brand new ford itemsjust 300 miles usage.
its got the following spec.
2050cc rebore and new pistons.
recon 1.8 ported head.
focus rs head gasket.
kent cams and pulleys.
all the tappets/ valve springs/ seals etc are new but they are only standard spec.
i was wondering if the standard spec springs and tappets are the reason that they have gone already?!?!?
it revs quite high with the megasquirt management
