Chevy 2500 HD Question

MCL · Dec 30, 2010

I have a 2002 Chevy 2500 with 6.0 gas engine. It has just over 100000 miles. Both exhaust manifolds appear to be leaking where they bolt to heads. Is this a common issue with these or am I just lucky? Anyone here ever change any? Is it a big job or should I let a professional do it?

Serious responses only please. Any suggestions to go buy a Ford or Dodge will be ignored.

Seriously my 1999 Ford v-6 leaked too.

Removed plastic inner fender well easy to get at,

now be prepared to fix (Drill @ Tap) any of the
bolts that snap can't tell you about the Dodge but i can't believe it would be much of a different story.

Chevy 6.0 have a known problem with exhaust manifold bolts breaking off or the manifold itself cracking. Don't feel like your the only one.

It looks like the frontmost bolt on both sides has the head broken off. It that an aluminum head or cast?

I've got Fords, Dodge, and Chevy trucks. Have had that problem on all of them.

I remember that problem on Nissan 3.0 V6's but not Chevy 6.0's.

I have heard that a lot of power can be found by swapping the rockers out for a higher ratio set and installing headers. Gonna have those manifolds off anyway, right?

I couldnt tell you. You will have to examine closer to find that answer. Sorry I couldnt be more help.

well this is one of the problems that happens when a person drives through water and it spashes on the hot manifold.

saw a TSB on it, I beleive, while looking for dash information on my own. Expect both front hub bearings (4WD?) shortly, and the instrument cluster should start acting up any day now! Great truck otherwise! FYI, GM replaced all the injectors on my Duramax '05 under warranty with 160k on it.

have repaired lots of them, a small right angle air drill is your best friend in most cases, some can be reached with a regular drill by removing the fender liner, but if you end up with the rear ones broken most likely you will have to pull the head. removing the head is a large job but as far as head gaskets go those late model chev engines are easy.

those should be Aluminum heads; only the year 2000 trucks had cast iron heads. Took me 3 weeks & $500 in ADDITIONAL tools in my spare time. Had to wait over week for new manifold. DO NOT buy an aftermarket (cheap) manifold. It is a bee-itch of a job, not hard, just tedious.

Hey Guy

Just read about recall on 2011 ford trucks fire danger, check your serial number before you park that bad boy in the garage.

I guess heating the manifold bolts so they don't twist off is out of the question with the aluminum heads? Got any $$ figures I can expect?

I was really hoping this thing would be paid for before I had to start major repairs. Designed to go 100000 miles and start falling apart.
