On 4x4 S-Trucks, the front driveshaft interferes
with the stock V-8 oil filter location and must be relocated. On a 2WD S-Truck,
a relocated oil filter is not required, but it helps with the exhaust routing.
Corvette LT1 engines use an offset filter adapter for exhaust clearance purposes.
On the V-8 S-10 4x4, this greatly simplifies the problem of relocating the oil
filter without the problems of oil hoses and fittings that can fail and destroy
engines. On the 4x4 trucks, the engine must be offset toward the passenger's
side slightly for the filter to be a safe distance from the driveshaft. The engine
must be set-back at least 3/4" for the filter to be a safe distance from
the front differential. We recommend that you position the engine so that there
is at least 3/4" (preferably 1") between the oil filter, the driveshaft,
and the differential.
The offset oil filter adapter uses the 4.3 V-6 oil
filter, which is narrower than the standard V-8 oil filter. Notice how close the
filter is to the pan. This offset adapter may not fit aftermarket oil pans. The
adapter is easily installed and uses a bypass valve to prevent engine damage if
the filter gets clogged. GM no longer has the part.
still has a limited supply, complete with hardware, gaskets, and instructions, for
$99, including shipping (Part Number S10-112)
