#239 of 399 Granitizing kit by jesse27467 Aug 03, 2008 (6:14 pm)
My dealer keeps trying to sell this to me claims it improves mileage. I have a 2006 with 30000 miles on it. Any good? Replies to this message: dmathews3 (Aug 04, 2008 3:13 am) leadfoot4 (Aug 04, 2008 12:05 pm)

Replying to: jesse27467 (Aug 03, 2008 6:14 pm) Only thing it improves is his pocketbook. Don't you think if it worked GM would include it as standard equipment on their trucks since they are losing there you know what due to the poorer mileage of trucks? I think I would think about finding another dealer that was more up and up with his customers than trying to line his back pocket.

#246 of 399 Engine Tapping at start up by bonz1 Sep 14, 2008 (1:21 pm)
I have a 08' Colorado, I-5 with 4500 miles. My question is at cold start up I hear what appears to be the valveIt only lasts for 2-3 seconds. Just don't feel that the engine should do that. Took it to the dealer and was told it was baffles in the muffler.(?) Didn't believe him and it still occurs. Back for a second trip. Tech checked the settings and was told that it is normal for the truck(excuse). Stopped back and started 4 vehicles with I-5's. 3 out of 4 tapped at cold start. The one that didn't had been driven earlier. Love the truck. Power is great! comfortable but if this thing is going to suck or bend a valve at 50000 miles I'm going to unload it. Has anyone else been experiencing this?

Replying to: bonz1 (Sep 14, 2008 1:21 pm) In some trucks it is a normal sound of the fuel injectors. Replies to this message: bonz1 (Sep 15, 2008 4:37 pm) jpf (Sep 17, 2008 7:25 pm) poncho167 (Sep 20, 2008 10:00 am)
