When was the gerotor added to the GM 3800 engine?
When was the gerotor added to the GM 3800 engine?
As the engine evolved into the Series I, a gerotor oil pump and roller lifters were added in ’86, on-center bores were added in ’88 along with the balance shaft, and a one-piece rear seal was introduced in ’90.
When did GM recall the 3800 Series 2 engine?
This increased fuel mileage by a substantial margin and provided GM some engineering success. In fact, the 3800 Series II was on the Ward’s 10 Best Engines list 1995 through ’97. However, in April, 2009, GM issued a recall on 1.5 million vehicles with this engine due to an oil leak issue that could result in a fire.
How tall is the GM 3800 Series 2 engine?
While the stroke for the 3.8L engine remained at 3.4” (86 mm), and the bore remained at 3.8” (97 mm), the engine architecture changed dramatically. The deck height is shorter than the Series I, which reduced its weight and total engine package size.
When did GM change the crankshaft balancer on the 3800?
Use the following procedure to properly service the crankshaft balancer on these engines. According to GM, there has been a running design change in the crankshaft balancer. This change affects 3800 engines built late in the 1995 model year (L27 and L36) and all of 1996 model year (L36 and L67).

Where is the dimple on a GM 3800 engine?
The crankshaft balancer designs can be easily identified by a dimple stamped in the face of the crankshaft balancer (see Figure 2, view B). This dimple aids in the alignment of J 38197-2 and also identifies the crankshaft key location in relation to the slot in the crankshaft balancer.
