Need some input on lower intake install

StangerBanger · Sep 4, 2015

ive heard some people say that after installing a new intake, you need to go back and re torque the lower intake bolts once youve run the engine. the only problem i see here is that the lower manifold bolts are next to impossible to get to once the upper plenum, fuel rails, wiring harness ect are on. is it really necessary to take all that stuff off again just to re torque those lower bolts? anybody have experience with this? blue loctite maybe???

I never did. . Never had an issue. . Just use the right torque sequence.. i even put some boost thru it for a lil bit..

I never re did my lower and when we pulled it out after only about 5k on it the bolts were not properly tightened anymore.

They were initially torqued in sequence to correct specs according to Haynes manual.

I've never done it either. And I have done lower intakes a million times.

Agreed on the correct pattern, torque, and I use a light coat or RTV. Use good gaskets, blue rubber on the valley seals NO CORK!!
