actually that gasket is 11.50. yea that would be the easiest way, as pulling the intake only takes only about 5-10 min. the only thing is i installed a pcv catch can not long ago with prevents the upper intake area from guming up with oil and such, making a leak harder to detect. So i guess i will have to turn the key on with the manifold off to prime the system, then look for leaks. i may pull the egr again also and give it a good cleaning.
