New member, with first problem ever with my van, 2500 V8 6L. 160 000 miles. Sounds like a typewriter when I start cold, and disappears after 5-10minutes. Guessing a bad lifter. What is involved with a repair, and is there a fix to get rid of the noise [different oil?]. Can it be repaired without removing the engine? Want to know so I dont get ripped off, as I dont have the knowledge to do it myself.

I read about a something you can flush the engine with to help get rid of the noise. It was on this forum, I've been searching, no luck yet. As for the repair I'm not to sure how in depth it is.

"If it lasts more than a few seconds it is not normal (less than 5). You can try finding a shop that has the newest BG oil flush chemical and machine www.bgfindashop.com I have seen THIS machine take care of several lifter noises. You can also try a quart of Lucas oil treatment."

Took this from a post MDTAHOE made. May help, may not. I think its worth a try, rather than have to tear into it.

I have heard of positive results from people who have used Marvel mystery oil. Pour some in the gas tank or add it to your engine oil.

i have a 2005 express 3500 6.0 engine and at 317,000 miles, the lifters are noisy below 50 mph. runs well at 50 mph or over. am saving to buy a surplus engine or refurbished gm engine. did my oil change every 3500 miles at chevy dealers across southern california. body is a cut-away (14-foot box) - makes it easy to load and unload standing upright (unlike cargo van body where you are crouching). gvw is 6500 but suspensions set to carry 6000 lbs. although i often load 6500 to 7000 lbs of new car tires for delivery to car dealers. never had a problema going thru the weighing scale chp checkpoints. will look for band-aid solution to this noisy lifter problem.
