Hello all!
So, I've got another head scratcher. I've just finished my timing chain job, (2010 LR4 5.0) and I've run into an issue with my bank 1 (passenger's side, US model) timing chain. Long story short, I can't seem to get it to keep tension. When I set all my cam variation pre tension, the chain is tight like it's supposed to be. However, when I release the cam lock, the exhaust cam turns a little to release all the tension, then I have a TON of chain slop. Since I have already put everything back together, I'm trying VERY hard not to have to pull it all apart again, but I'm getting very close to that point. My fear is that the brand new tensioner I installed isn't functioning properly and isn't maintaining the "slack tension" on the chain. I pulled the valve cover and passenger side timing cover back off, all timing marks are correct, it's just the slop. Since the tensioners are spring loaded hydraulic, I wonder if there's something. in the oil supply line?
FYI, as I have been test driving it a little, I noticed that its throttle response is sluggish, and it take's it a little bit of struggling to start. It does middle quietly and smoothly though. That said, I didn't drive it much, and tore it back down. (insert sigh here.).
Has anyone run into this before? I've done a few of these year model rover chain sets and never had problem...this time is different though. (I'll post a video shortly)
oh yeah, I did loosen the tensioner rail bolt to see if perhaps the rail was jammed....it is not. (SMH)
