Looking for a good shop in north central to eastern WA
 

My dear old girl (circa 1997, unmodified engine) has developed a significant oil leak out of her top end. Spoke with Cummins NW in Spokane and was told they only work on the heavy metal and don't even have the right equipment to work on the small block engines.

Hoping a forum member in my neck of the woods can suggest a good shop to not only fix the leak but go through the engine and make sure she has as good a second 200,000 miles as her first have been. Looking for facility located on or east of Hwy 97 from the Canadian border to Wenatchee and then as far east as Spokane. Recommendations to go to as well as warnings to stay away from will be most appreciated.

Thanks
