1. The online manual staes you need to pull the head to change the timing chains. Is this true?
2. Why can't you just drop the oil pan?
3. Has anyone change a timing chai on this before & how long did it take.
4. Why asking is that I hear noise for the frot of the engine and truck only has 74k and I get preignition ping . Using 93 octane removes the ping.
5. I have read that these are nisy engines..is this normal??
6. EGR works when i pull a vacum.
Thanx
