20 Most Recent 1990 Chevrolet Suburban Questions & Answers

Question edited for clarity, typos, real sentences and stuff. Question moved to model category. By 'spray it', it presume you mean spraying with Easy Start?

When replacing the intake gaskets you will need to use rtv in each corner (front and rear each side) on the china wall to seal rubber seals for the front and rear across the intake area. If you did not get the rubber seal across the china wall you can put a heavy bead of rtv across and seat the intake in it, just don't move the intake after seating it on the engine. Hope this helps.
