Hi guys, I own a 2000 Blazer equipped with the 4.3 vortec. I have replaced my spark plugs about 10.000 miles ago. Im using standard NGK plugs.
Here´s what one of them looks like.
What does the dry oily crusty mean? A oil leak?
By the way, I´m feeling that the engine it´s not running all that smoothly from time to time, looks like a faint pinging or hesitation. I really dont know how to describe it.
Thank you...
