Upper Engine Oil Leaks On
1989 Suzuki 1.3L DOHC (VIN 3) Engines
There have been instances of oil leaks on Suzuki 1.3L engines manufactured before February 10, 1989, caused by the front camshaft oil seal coming loose. Suzuki has found that this problem may be corrected by reducing the width of the seal. The original oil seal had a width of 8 mm and it has been replaced
with Part #09283-32026, which is 6 mm wide.
When installing the new seal, it is suggested that the front camshaft bearing cap be removed. The seal should be installed so that the outer seal surface is flush with the machined surface surrounding the seal bore. It is critical to ensure that the outer portion of the seal is not recessed in the seal housing bore (see illustration). Seal recession may restrict the oil return passage and cause premature oil seal failure. Re-torque the camshaft bearing cap bolts to 84-102 inch lbs. and the rocker cover bolts to 36-42 inch lbs.
Finally, inspect the timing belt for oil contamination. The belt should be replaced if there is any contamination or residue present. Operate the engine upon completion of this procedure and inspect for oil leaks.
