Egr cooler delete questions

Are you doing the EGR delete because of existing problems, or wanting to avert potential problems? The reason why I ask this is; if you are having issues such as coolant blowing back out the degas tank/reservoir, then the damage may already be done. Have you had the Oil Cooler replaced in the truck? Does your dad flush the Coolant system annually? If you elect to go with ARP studs, I strongly suggest to have the heads taken to a reputable Machine Shop and have them magnaflux, and check surface for warpage. You will likely find the heads have cracks around the valve seats also. If you go with the EGR delete kit, give consideration towards the Oil cooler also.

No if the truck is running fine with no EGR problems you do not haft to install head studs. But if you do install a EGR delete i would go ahead and install a new oil cooler you are pretty much there so why not cheep insurance you can buy both off e-bay for less than $600.00. And yes if you do do head studs i would be shure to have them checked and decked.

My opinion is if you are going to do any of that stuff, you might as well bite the bullet and do it all. Studs, gaskets, EGR delete, remove scoop from up pipe, clean the turbo, have the heads surfaced and checked and put all the intake parts in the parts cleaner. It's a $3500 deal, but it's also like having a whole new motor, that is more reliable. my .02cents.
