After having my 2006 with 4.7 checked out because I thought it had a lifter tick, I was told it's an exhaust leak at the manifold. They wouldn't say much more than that and it sounded like something I can fix at home. So I did some research and found this is a common issue. I just got done taking a look for myself and here's what I need help with so far.
The leak is on the right side of the engine, so I got under and looked at the bolts. The ones I could see where all there and looked fine. The only issue I could find was that one of the bolts holding on the heat shield is loose. I tried to tighten it and it just turned without tightened. Does this bolt hold the manifold on also or just the heat shield. I'm hoping I found the problem but don't want to go any further until I know. I have a habit of making easy jobs hard by not stopping to ask before proceeding, so I thought I'd try the easy way this time. lol
If this could be the problem, how to you fix a broken bolt in the manifold? I know it's common to break these bolts but I don't know how to remedy the problem If this bolt isn't involved with the manifold, can somebody give me a bit more in depth fix it plan to locating the leak and fixing it?
Thanks for any info you have on this project, if you need any info that I didn't supply please ask.
