This is often caused by a faulty non return valve in the oil filter. Just try a new filter as they vary. ryco are OK but I have found Perolator the best. Regards Philip A --Previous Message-- : Hi Guys, : : I have replaced my old 3.9L V8 (as some : of you know) reasonably recently with a : new 4.6L V8. The setup was a brand new : block with reco heads, new cam, tappets : rockers etc. : : I have done about 1000km with the new : engine and notice that when cold : starting the engine in the morning (as : cold as it gets in Darwin anyway) that : there is quite a lot of what seems like : lifter noise for a second or 2. The : noise pretty much quietens down : straight away. : : Until the car warms up a bit (a minute : or so) there is a bit of discernable : lifter tick. Once the engine is warm, : it runs nice and quiet. : : When I put the cam, lifters, push rods : and rocker assemblies together, I : purchased a shim kit for the rocker : shaft mounts and set pre-loads as per : instructions on both the shim kit : packet and the RPI V8 website (can't : remember the tolerance I used but : obtained and verified these tolerances : with the Land Rover rep in Adelaide : where I purchased the engine). : : Just seems odd firstly with the cold : start noise and subsequent lifter tap. : Previous rangie engines I have had have : never had that initial noise and only : have lifter tick after the timing gear : starts to wear. : : My question is if anyone else has had : this sort of thing occur and whether or : not it is normal for Hydraulic Lifters : to lose their prime?? : : Any help or experience would be : appreciated. : : Thanks :
