Sparkies No Beno

[augman]

*UPDATE* - Changed spark plugs today.

Today I installed a set of ACDelco # 41-962 plugs. I removed ole obsolete ACDelco 41-985 plugs that I had cleaned up(see pics in post# 1 here) and re-installed back in Dec of 2018 when I had first purchased the vehicle with 131k miles. Back then it was burning and leaking oil like crazy. Folks here told me to install a catch can. This showed me it was catching an oz of oil every 100 miles. This amount of oil being sucked into the combustion chambers had "stuck" the piston rings. It also needed a rear main seal. I did a little research and discovered TSB# 10-06-01-008M: TSB# 10-06-01-008M So I did the valve cover update, installed the bypass deflector, and did an extra long piston/combustion chamber soak with Gunk brand "Motor Medic". I also replaced the rear main seal.

Today vehicle has 171k miles, it doesn't need any makeup oil between extended changes, the catch can doesn't catch much of anything, and it's dry as a bone underneath.

Below is a pic I took "today" of the ole plugs that I pulled out. They have 40k more miles since I cleaned them(see pics in post# 1) and no sign of oil burning. YEAH!
