Title: Intake manifold bolts leaking
Post by: silverchev08@gmail.com on October 06, 2019, 02:52:23 PM

GMC K20 5.7
Intake manifold bolts leaking oil. New intake manifold gasket and I sealed all the bolts with gray RTV however the center ones keep leaking oil. Was curious if there is a good sealant out there to seal the threads and bolt . Oil keeps pooling between manifold and valve cover. Really annoying.
