Advice Needed on Engine problem
Started the truck up and heard a little ticking noise in the engine, poped the hood and got close and sounds like air squezzing out somewhere, when I rev the engine it gets faster and my dad thinks that it could be either the lifters under the valve cover or there could be a leak in the exhaust headers conecting to the manafolds. I think that this is pretty weird because this happened just after the waranty expired. Anyway, just wondering If anyone out there has had a prolem the same or similar to this.

Our engs. don't have lifters. You can hear a light ticking sound which is the injectors--normal.
IMHO, you have a plug about ready to blow out of the head. You don't want that to happen. It will ruin the head. There are only 4-5 threads holding the plugs in--in an aluminum head--soft metal. Don't drive it above a small throttle opening--don't go into BOOST until you or someone checks the plugs for tightness. In fact, I wouldn't drive it at all until they are checked. They should be run down snug and then just 1/16th of a turn more.

lightninrod, actually the lightning engines do have lifters, and that ticking noise you hear could be a lifter, could be a burned exhaust valve, or just a small exhaust leak, but a small exhaust leak would generaly go away after the engine is warmed up. Does the noise change with engine temp? Does the noise increase with engine rpm, does it get louder with engien rpm or does it stay at the same loudness? If it is a plug starting to come out of the head yoiu would be able to feel it by putting your finger on top of the coils, check each one while the engine is running, you will feel it at the same time that you hear it. Generaly there is no noise before the plug blows out. You can also take a piece of say 1/4" vaccuum line about 3 feet long and put it up to your ear, and move the other end around where you think the noise is coming from until you can pinpoint the noise. Just my 2 cents.

No, it doesn't get louder while reving it, but the clicking/ticking sound goes a lot faster and the more engine noise almost drains the noise out. So you can really hear it unless its ideling our going under... Id say around 30mph. I've pinpointed it to the passanger side so I'll try takin that valve cover off and check it out. Oh yeah and I did do a little looking into about the lifter thing and they aren't called lifters... they are some other name but relitivly do the same exact thing.
