Fix it now...before it breaks?

If it were mine I would do the studs and EGR delete before anything else........but not everyone has access to a shop whenever they need it.

EGR delete will be a HUGE help, but wont cure what the 6 ohhs got.

I agree with Dave, with one addition....you need to do the STC fitting as well your working on borrowed time there.

Until I have to, studs are on the back burner. All the rest is hopefully in the future. To replace the standpipes the valve covers have to come off? I read somewhere you need to jack up the pass side to get the cover off. Is that right? On a level of 1-10, how tough is it to tear it down that far to do the stc, egr delete, oil cooler, dummy plugs, standpipes, ect. Any special tools? Won't be doing this until it warms up, so I have time to ask questions, research, gather the items, tools, and get the confidence to tear into it.

Pulling the valve covers does not require jacking the engine up, just some patients and a bit of wiggling. A 12mm - 1/4 drive - wobbly will make this task much easier.

To replace the standpipes the covers do have to come off, but the HPO rail can stay. There is a 10 or 12mm allen that holds them down, once you remove the fitting the pipe might come along with it - or you might have to dig it out with some needle nose pliers. Dummy plug is the same, just in the front of the rail - and no pipe attached.

If you have never worked on a 6 ohh before, and are fairly mechanically inclined....I would rate the work you are looking at doing a 6-7 on the skill/ patience level. If you have spent some time under the hood of a leaker, its just another job.
