Decided to treat the old girl to some fresh plugs today. NGK platinum's. Figured might as well to a compression check when all the plugs were out.
For those who have not seen my earlier posts on this truck.
It's a 1997 Chevy Silverado extended cab 5.7, auto. 167k miles. I've only had it for a couple of months.
My brother gave it to me. He really didn't do any maint. on it. And no records from the previous/original owner. Original owner used it tow his ski boat. I think he had a couple of teenage boys, who I'm sure ran it hard any chance they got.
Compression is as follows. Engine cold, throttle not held open.
1 190 2 191
3 195 4 192
5 190 6 197
7 190 8 191
Old plugs were AC Delco's Not bad looking, a little oily/carbon build up. Truck really needs an Italian tune up. I just put around in it.
Thoughts???
