How do you fix a noisy lifter on a 1986 Chevy V6 pickup?

Answer 1

Short of replacing the lifter there is something you can try which works many times. You vehicle has hydraulic lifters and sometimes they can become partially clogged with gunk which causes the lifter to stick. I have done this many times with great results, but there is no guarantee this will work. Purchase a can of Seafoam Motor Treatment. I will post a link to the product so you can read all about it and see what it can do. Add 1.5 ounces of Seafoam to your oil. If your Chevy holds 4.5 quarts then add 6.75 ounces of Seafoam to the oil. I suggest you change the oil/filter and then add the Seafoam. Drive the truck for 1,000 miles and then change the filter and only the filter. Add enough oil to compensate for the loss when changing the filter. Drive it for another 4,000 miles and then change the oil/filter. You should see great results. You can get Seafoam at most Auto Parts and Marines Stores. Walmart has it in some areas. Also add a can to a full tank of fuel to clean your injectors.
