Upon further investigation, a technician may find oil leaking from the high pressure fuel pump area.

Refer to Fuel Pump Removal in SI. •Remove the camshaft cover. Refer to Camshaft Cover Removal in SI. •Remove the camshaft cap (1). Remove all excess sealing material from both surfaces. Note: It is critical during installation to ensure the bearing rear cap and cylinder head alignment is correct and the mating surfaces are flush. • Ensure that all sealing material has been removed from the components and the sealing surfaces are clean and free of contamination prior to applying the sealer. • Install and align the rear cap within 20 minutes of applying the sealer. •Apply a 2.5 mm (0.1 in) bead of sealer, GM P/N 12378521 (in Canada, use P/N 88901148) to the cylinder head at the number 6 intake camshaft rear cap mating surface. Note: Apply the sealer to all locations centrally locating the bead on the rail. • Run the bead to 5 mm (0.2 in), dimension "a", as shown. • Where the cap ends on the perimeter rail, extend bead approximately 4 mm (0.2 in) beyond edge of cap. • Run bead, dimension "c", 32 mm (1.3 in) from the edge of the cylinder head as shown. • Run bead, dimension "b", 20 mm (0.8 in) from edge of cylinder head as shown. •Install the number 6 intake camshaft rear cap. 6.1. Tighten the cap bolts evenly to 5 N·m(44 lb in). 6.2. Tighten the cap bolts evenly to 10 N·m(89 lb in). 6.3. Back the cap bolts out 120 degrees. 6.4. Tighten the cap bolts evenly a final pass to 10 N·m(89 lb in). •Install the camshaft cover and gasket, GM P/N 12609291. Refer to Camshaft Cover Installation in SI. •Install the fuel pump. Refer to Fuel Pump Installation in SI. Important: When installing the fuel pump, install a NEW high pressure fuel pump O-ring (GM P/N 12600313), high pressure fuel pump gasket-to-cylinder head (GM P/N12595951) and high pressure fuel pipe (GM P/N12615401).

Does the engine roll too? Haven't had to fix an SS with this problem yet. |
Yeah...really extreme in low.....I sometimes use low leaving work as we get piled up leaving the complex and low allows me to stay off the brakes...anyways noticed while
lightly getting back into gas the eng will thump over and then do the same when getting off the pedal...keep in mind I'm barely touching the petal to go, Ive experimented to make sure it wasnt just me....figured maybe a mount os stretched or loose or sloppy...do there have tq links? That was my first guess....I played with it in the driveway one day but couldn't pin point it by myself... its either that or I have one hellofa slop in my diff! |
