I read a really interesting article off the RPI website why they stated they don't recommend synthetic oils since the light viscosity drains quickly from the lifters--hence noise and premature wear. I will try and dig that up.

what about a clunking noise, from the engine compartment on a 97' D-90. Sounds like something slapping the side of the oil pan, has been doing it for a while but seems to be getting worse, doesn't do it at high rpm's. runs great, only 49,000 on whole vehicle and less than 12,000 on new motor that was installed about 3 years ago, I am the second owner, my dad being the first and i am not sure if the last motor did this? any suggestions are these noises common? If anyone has any ideas i would appreciate it, you can email me at spencer08291985@yahoo.com. Thanks

Jim,
I had some "lifter noise" on our disco and it turned out to be the rocker arm assembly which had then worn out some pushrods. Replaced the bad pushrods and rocker arm assemblies and all has been great since then. I have used Synthetic in both Rovers that we have and it seems to be great. You want to be sure to use a synthetic based on the temperature of where you live though. In the winter, I can sometimes get away with a 5w40, but I usually go with a 10w40 and haven't had a problem. The 5w40 works very well for cold starts, and the engine catches faster. If it is already warm out, the 5w40 will cause slight lifter noise at first for just a few minutes, then it's fine. The 10w40 never causes any noise no matter what the temperature now that the rocker arm is fixed. Hope that helps!!

Lifter noise all the time? Only during startup?
What viscosity oil are you using?
Also, when the header gaskets start to go, they sound like lifters.

Spencer. If it sounds like clunking in the oil pan, I highly suggest taking the pan off and checking it.
