What about a clunking noise, from the engine compartment on a 97' D-90. Sounds like something slapping the side of the oil pan,(when i think of what it sounds like i think of an oil stirrir on a briggs and straton motor if anyone knows what i mean) 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 firstname.lastname@example.org
P.S. I am not very fimiliar with this site,If someone post a reply on the website to my question how will i know?
