UPDATE I wasn't able to find anyone with a stock engine with this problem.(Seacrhing the forums and internet) So I called the repair shop that had previously done some work on my truck (about 5 weeks ago) and they were very skeptical as well. They recommended that I have the truck towed to another shop for a second opinion. Since I was away form home, i didn't know a reputable shop in the area. I didn't know what to do. The truck broke down in California and my shop was in Nevada. I found a transport company to pick it up from the GMC dealership and take it to my shop 170 miles away. The shop got the truck yesterday and my wife picked it up today. The dealership was right that there was a problem with the #5, but the problem was a broken valve spring not a washed out cylinder. Turns out this is about a $13,000 difference! I feel like i won the Lotto!! How can a dealership completely misdiagnose something like this?

The truck is completely stock. Also I do not beat the truck. The dealer told me that they do not rebuild motors anymore because the labor cost equals the new motor price. I think it must be just the rings because the block is cast and so are the pistons. i got a quote from another shop, and it wasn’t much different for a Jasper motor. Just a big shock for a truck that was running great. I did have to add oil between the last oil change, but I just figured they didn’t fill it up all the way. But never gave me a check engine light until it did. The motor R&R is about 12,500, there is another line that is leaking that’s an additional 500, then tax. Bringing it to 14,000

Motor remove and replace $14,000 ouch

Got the word from the dealer. fuel injector leak caused a blow by on #5. 0 compression on #5 recommend engine replacement. no estimate yet. damn.

Where do I start? I made sure the map was plugged in, checked to make sure all the plug wires were connected. Everything looks okay. what’s next? do I take the valve covers off and check the springs or have it towed to the stealer?

Was driving down the highway, got off at the ramp, then my truck was shaking, wouldn’t idle and engine light was blinking. It is really hard starting now and runs like crap! My truck has 109000 miles, receintly had condenser replaced, spark plugs and trans fluid replaced codes are P0106 and P0300 appreciate any help!
