So i have Liberty 03 3.7 V6.
It started making a noise pointing to the lifters being shot. This was both on idle and load. So off to Jeep to get a fresh set of 12 the lifters were in and guess what, noise is still there but less and now only on idle.
So after hours and hours of trawling every know Jeep forum and club site and translating a few Russian and chinese sites ,and phone calls to a few half in the know Jeep machies in the good ol USA we have come up with nothing.
We have removed the cams and checked the cam lobes, checked the valves and springs and valve seats. we have checked the chain and guides and all the pullies and gear wheels. We have stuck a scope in to see if the pistons are ok and we have also checked the bearings. We have checked the water pump, aircon power stearing and inersia fan and electric fan.
We have checked oil preasure and the pump, and done compresion tests. Changed all the plugs and coils and cleaned the intake as well. We have checked the motor mounts and gear box and transfer case mounts and checked the drive shafts.
So this now leaves me still wondering and searching what the hell it is. The car performs greats and there is no power loss.
Im left with a functioning car but still on idle in and out of gear a nice "tuk tuk tuk tuk" sound.
Is there anyone out there who has experianced this or something similar.
