Yeah, I used the gaskets that came with the IMS. I still have the oil pressure prob. so, I gotta take it in to the dealer. That is one of the reasons I took off the IMS. I didn't want it on there when I took it in. I have heard of some others having the same problem with the pressure reading high and it ended up being a sensor or something. Scary none the less.
Took the truck into the dealer and the oil pressure thing is normal, when the truck is cold the needle is supposed to move in relation to engine speed... higher speed = higher reading. So, I still don't know what the deal is with the IMS gaskets. I don't know why they went bad. I would like to get some fresh ones and try it again. Nobody has wrenched theirs off to take a look?.. Brutal? I'm still curious if I'm the only one with the gasket problem.

i could have told you that.....................sorry not to sound asslike, but i noticed that since the first day i bought my truck and it only happened when cold so pretty much assumed it was normal. and since plenty on here have described the same thing before, it should quit fluctuating after motor is warm.
but i understand the concern as some have shown before. but its makes sense since the oils viscosity is very high when the oil is cold.

First of all, it looks like a heat issue to me. However, I'm not sure why they would be affected since the stock gaskets have done fine with the same amount of heat.
It could also be some kind of abrasive that got in there. I know brake parts cleaner will eat through rubber and foam like nobodys business; it would wreck those gaskets. Did anybody clean your engine with a de-greaser? (car washes usually have this solvent) What about any oil getting sucked in by your air filter after a cleaning?
I find it highly unlikely that it was an over tightening issue. When tightened, the gaskets will tuck right up into the crevice without overlap. You would have to severely mess up putting in the gaskets for that to be an issue, and even then the damage wouldn't look like that.
Still pretty scary, I just installed my IMS yesterday afternoon.

Nothing of that nature has ever come in contact with those gaskets while they have been in my hands, during install, or after. and I have a dry flow air filter. I am still waiting for someone else to check their gaskets to find out if there are any other problems. Will wants me to fork over 45 bucks for new ones, which aint gonna happen so I guess the IMS is now a big paperweight I never should have purchased. I'm not too stoked about the fact that the possibility of them just being bad from the get go is just being blown off. Like I said I am wondering if anybody else has this issue as well, but just doesn't know it.

If you had over torqued the gaskets, they would have seen mechanical failure. Your pictures show a completely different failure mode. The failed gaskets looked smeared meaning there was chemical failure or thermal breakdown (i.e. melting). Gaskets designed for automotive use must endure the typicaly solvents found around cars. It is very unlikely that the gasket saw a solvent that caused it to fail. Melting seems to be the failure mode. The gaskets should be returned to the vendor who will also want to know what happened. Simple chemical analysis tests will uncover the truth.

Yeah, you can see some of the gaskets are melted due to heat. That makes me wonder... in the stock location on the intake plenum, or runner manifold, they are only in contact with metal on one side, but with the IMS installed they are sandwiched between two metals. Maybe the heat is too much for them. I contacted the vendor and he just seems to want me to pay for replacements, but I'm not about to fork over more money and have the same thing happen.
