Timingchain advice on 4.5
Today I pulled the cam covers off and removed alternator, steering pump, radiator fan and shroud to gain access to the bolts for the timing chain guides.
I have removed the cam oilers so I can clean them and replace the plastic clips etc. On inspection of the cam's they look to be in very good shape. No scoring or flat spots. As far as the chain is concerned, I wanted some advice. It looks to also be in good shape with no slack when I try to pull up on it at the top. I noticed it has a master link. Does this mean it is a replacement? I was of the understanding the original chains have no master link? Also I noticed on the drivers side the head casing looks like it may have been gouged slightly by the chain (possibly the original) maybe the reason the previous owner replaced it? My question. Is there a definitive way and I can make sure this chain is good? Or would you just go ahead and replace anyway?
My next question is. The inside of the cam covers have some kind of sealant that has been applied at some point. (pretty ugly looking) Why would they have put sealant in there?
Any other advice while I'm in there would be greatly appreciated.
All the best John
