I am using about 1 bottle of premix coolant every other week and I see a small puddle of red coolant where the intake bolts to the head/block. I have read the sticky on LIM gasket changing, however I was wondering how hard it is to do yourself or if I should have it done. Does anybody have a parts list and pics of the procedure, and anything eles it could be? Thanks

Many find it quite easy, even as a first mechanical fix.

Please search for the parts list and costs. It is around here many times. Figure ~$250-300

Thanks for the info. I have found the part number for the gasket, but does anyone know where to get the plastic intake, is it worth changing?

Absolutely change the intake. APN has a very comprehensive kit with a reinforced EGR area that seems to be the best at the moment.

I am going to get the "new and improved" upper intake. My Mech. says he will charge me 200 if I get the parts, so I think I will let him do this considering I have 2 jobs and work on weekends too. thanks for the info

the only improved intake is the APN like boosty said because of the steel sleeve and i think its about 70$ in youre area .don't forget you need to change both the UIM and the LIM gasket

Anyone have the PN for the LIM gasket? The APN manifold comes with the upper.

the best gasket for the LIM is the aluminium one from Gm pn 89017816 i think that the part no

Thanks for the info guys!!

Best pricing I've found on it is at Intense-Racing.com or GMPD
