99 Yukon making scary engine noise at start up then goes away
I have a 99 Yukon 103,000 miles and have had it 2 years.
Recently i went to start it up to go to work and it made a noise similar to a bad lifter but a little louder . After about 30 seconds it sounds like it goes away completely.
If I were to guess its almost like some part of the engine is not getting oil at start up.
Im a little worried that the more i start the engine up the more damage im doing and soon will have a costly repair bill.
Any idea's what it could be ?

Im tempted to change the oil and use a additive to see if that helps.
My real concern is if it is just a sticking valve am I doing any long term damage to the engine.
I also have a 1999 Yukon but I have had mine for 6 years and 144k miles of great performance. I have never kept another vehicle for this length of time nor driven this many miles but I love this vehicle. However, that said, I too have had that clicking/clattering sound occur and it is really doing it at the moment. Several very knowledgeable friends tell me it is a lifter value and they make that sound as they start collapsing. It is made the "scary noise" on cold start ups occasionally for years. But this last week, it has been very loud and pronounced on start up and never goes completely away like it used to. I was advised to use an additive immediately and hope that it is a matter of "cleaning" the lifter values. The alternative is much more expensive.

I been putting resolin oil additive in mine. Seems to do the trick. Last oil change I used Lucas and it didnt do as well. Im afraid to flush the engine. In fear of making the problem worse. I've heard and witnessed horror stories about that.
