Hey guys! Been lurking the forums since I purchased my 2005 Ram SRT-10 about 2 months ago and unfortunately have an issue. Bought the truck with 77K miles on it and the thing ran great for the first week of ownership. Didn't drive it like a race car, just the occasional pedal to the floor to feel that power. Long story short, driving normal through town, it started running rough. Babied it 2 miles home and eventually got a code. Running rich and O2 sensor. After checking fuel pressure and replacing O2 sensor in hopes of a quick fix, I had to take to a dealership for further diagnosis. They determined I had a burnt intake valve on cylinder #8. I decided to do the tear down myself to save about $2K. I have been tearing down over the past couple weeks when I have the spare time. Anyway, I got the valve cover off today and found the issue was defintely with the intake valve on cylinder #8, but it is more than a burnt valve, it is a broken valve. Still have to finish the tear down and pull the cylinder head off. I know of course to look for the valve end that broke off and check for piston and piston wall damage, but is there anything else I need to check? Head will be going to machine shop for them to do their work. What typically causes a broken intake valve? I had no knocking/ticking, and the engine ran, just rough and rough idle. It was just was running super rich on the passenger side intake due to the exhaust gas running back into the intake. Sorry for the long post. Just want to get my "new" baby up and running. That 1 week of driving wasn't enough!
