Clio
Hi there,
Those of you who are familiar with this kind of engine, more so the head...
The tappet cover, does it hold the cams in place, or are there horseshoe brackets that hold the cams in place?
If tappet cover holds cams in place, then the next question is, if I get the cam/timing kits from Renault, will that hold the cams in place if I take tappet cover off without removing the timing belt? Or do I have to remove the timing belt regardless if you remove tappet cover?
Reason for the questions is I need to check for a dodgy hydrolic lifter or alikes, possibly the tappet which runs on the square lobe on the exhaust cam. Called a backlash compensator apparently (source: Renault).
Rather than taking everything apart and finding nothing wrong, then the rash of piecing all back together for nothing.
90% sure my metallic rattle (bit like a marble in a tin can) between 2k5 and 3k under slight throttle isn't dephaser, and 99% sure that its not bearing knock as the tapping has been there since new, and since clocked 60k over 3 years with a few trackdays in between. Dephaser is generally noisy at startup when cold at idle. Bearing knock disappears generally when hot and above 2k rpm. Oil type and quality doesn't effect rattle sound or intensity.
Definitely not exhaust manifold or associated rattle as tapping matches rpm frequency between 2.5k rpm and 3k rpm and is deffinately loud enough to be internal moving part related.
Advice/ideas/suggestions all welcome
Thx
