Ticking noise. Oil pump?

I started getting a ticking noise a little bit ago. Its in the engine bay and seems to be passenger side. Its not exhaust because i felt around and didn't feel air and it is more mechanical sounding than air an escaping noise. It ticks after the engine is running at normal temp. Im running thin 5-30 oil when I usually run thick 20-50. could the oil pump be making this noise? oil light is not on.

danmit! I was thinking a lifter or sticky valve too. I put some valve cleaner stuff in the engine and obviously it didn't work, but my hopes on a bottle of magic were low to begin with.

Take off the valve cover, you can probably figure out which rocker it is. Lifters chug at start up, rockers tick in my experience.

Mine has developed a similar ticking. How difficult is it to replace rockers?

Very easy to do. 15 minutes for passenger side, half-hour tops on the driver's side (pretty sure you have to pull the intake cover for that but you might be able to get the valve cover off without pulling it).

Personally, I would not run 5 wt oil, my engine likes 10-15 wt. Change the oil, I will bet that the ticking goes away.

Mine runs 20-50 dino oil... I need to check the exhaust to rule that out. I haven't had much time lately to tinker but maybe I can get back in the garage to check things out soon.

I take the opposite tack. I use 0w40 or 5w40 synthetic. Rocker wear is usually caused by build up and or poor oiling from too heavy of an oil/and/or running low on oil and/or lack of changes.

I run synthetic as well but since I was not the owner for the first 80k miles of my 110s career, I use 10-40 Mobile 1 extended in my motor and since my RRC has 220k miles I run 10-50 Mobile 1 synthetic in it.

It has been my experience that lower weight oils like 0 & 5 will cause valve ticking in rover V8s.

I use a 5-30 Mobil 1 in the winter and a 20-50 Amsoil in the summer. I changed the oil to 5-30 before I did a long drive up to Nova Scotia and back and since then I noticed the ticking. going to change the oil to the thick shit tonight and see how it goes.
