| | Updating GM’s Quad 4 Engine, Doug Anderson, Automotive Rebuilder, April 2000 |
| | GM had problems with excessive oil pressure caused by the relief valve sticking in the bore, so the original pump was superseded with a new version that had improved clearance for the relief valve. | | | It was used for the VIN D engines in ’87 and ’88. | | | The Quad 4 had four valves per cylinder, tuned intake and exhaust manifolds, no distributor, no plug wires, lightweight rods and pistons to reduce shaking forces, and a crank with eight counterweights that was designed to reduce noise, vibration and harshness (NVH) and bearing wear. |
