Getting new head

[2xtreme]

I posted a while back about my rig burning an excessive amount of oil. After the first attempt to fix the problem they have decided to order me a new redesigned head. They said a red flag came up when they ran my vin # concerning the head on my truck. I will get more details today when I pick it up, but it goes in Dec. 18 for the new head.

Yes, please post the information. I would be interested to see what series of H3s this was related to....

Please obtain the bulletin number, because I believe the dealer has no idea what is wrong. The only bulletins in regard to oil consumption that I can find are in regard to using engine oil dye, the PCV baffle.
The only bulletin that red flags a cylinder head has no reference to engine oil consumption, so let's hope it was the cylinder head and not the engine; or you will be going back again. (I'm not saying it could not be the cylinder head, since it could be a head or a cylinder head gasket. I'm just saying I see no bulletins red-flagging the cylinder head for oil consumption.)


The bulletin I believe the dealer is referencing is #PIP3935 - (10/03/2006), and had to do with misfire and the elongating of the intake valve guide; usually on cylinder #1. The complaint was usually rough idle, with the Serice Engine Soon Light on and DTC P0300 - P0302. It affected vehicles built prior to 287591 (Last six digits of the VIN).

So F5Fstop

my last digits of the VIN# are 275299

Should I just wait till it goes or what? What if it happens after my warrenty expires?

Not the kind of Head Job I look forward too

I can't say, other than the dealer won't replace under warranty unless it is bad. to be honest, I have almost 20K and my VIN is 100695; one of the earliest made, and I have not had the problem. Warranty spiked, and then started to go down; partially due to the new cylinder heads being released, and partially due to not all engines will be affected.

If you are burning oil, maybe you should push the dealer for a new exhaust manifold (internal pre-cat), a new main cat, and new pre and post cat O2 sensors. I don't know what all the burnt oil would do to the cats or O2's.

Really, and which dealer is this? Was it for the P code, with a rough idle?
Reason I ask is I'm curious if a change in fuel, that comes between winter and summer in MI, could have something to do with this problem. Something I have been researching on my own. I have my ideas on why this is happening on the early built heads. I actually have seen some correlation between where there are a large number of head replacements versus areas where there are few head replacements.
Maybe it is time to do another monthly report on cylinder head warranty to help prove my theory.
Out of six people I work with that have H3s, only one, has had the cylinder head problem, and all are early H3s, and all have quite a few miles. (I will say that the one who had a problem happens to be the person in charge of this part, which I thought was appropriate.

The heads were on back order from GM,, off topic, love the videos you guys made! I'm way jealous, we have nothing like that out here.

I soooooo wanted to say something smart about getting head in my earlier post but I was at my work terminal

Seriously though, what is considered an early H3? I want to pay particular attention to this issue if I have one.

F5 - something we have seen in the last few years in PA, typically during the winter months, is unusual failure of fuel gauges. Supposedly, this was being investigated, but I never heard of any official findings. Many suspected the gas. But if memory serves me correctly, a variable may have also been that the majority of these failures were in GM products...

is the cylinder head issue fixed in the '07 h3s?

[2xtreme]

I would assume so, since they changed the head design later in the 06 model year.

ah, it wasnt clear in the messages i was reading that they actually changed thr head design in the late '06's, because some of the messages were very current and those people were having head problems. it wasnt stated whether their vehicles were 06's or '07's. whew. thanks!
