Bent Tappet Lifters,, CDTI
As title says,, could i have bent some lifters. , story goes,, I removed an overcompensating diesel injector, removed copper washer, sprayed and wiped the seat. sprayed quite a bit of cleaner/lube in there.. fitted new injector checked and started.. that particular injector missed for 5 seconds or so then kicked into life.. BUT, now i have a Tap,Tap,Tap like a tappet knock.. though the car runs drives perfect and injector balances are now + or - .50mm^3... Im now wondering if the initial start up has pushed 2 valves up hydraulically and bent a lifter?. now on the cdti m47 the "lifters" are under the cams, one side the hydraulic tappet and other side the valve with a roller in the middle..
Now im hoping someone will have heard of a lifter bending under the pressure now giving me a tappet knock..?
