Tappet pinging noise???? Alfa 156, 2.0L, 16v, Selespeed
After repairing my starter yesterday, I took my car for a drive. Noticed a tappet pinging noise while driving in traffic especially when engine is hot. The heat guage was normal (90°).*
Also noticed it before at that temp.
Its Ok on low revs but pinging starts as soon as I floor it a bit.*
When engine has cooled down, its fine no pinging especially in the mornings, only when engine is hot and when weather conditions are high which sometimes reaches up to an abient of 30°C to 40°C in my part of the world.
Any comments will be highly appreciated!!!!
Could it be the oil i'm using pehaps (Motul. 8100 - 10W60)
