Mr. Gasket GM LS Timing Cover Alignment Tool

The timing cover and rear cover on GM (General Motors) LS series engines don't have any dowel pins to ensure correct alignment to the centerline of the crankshaft & this often leads to annoying leaks at the front damper seal and rear main seal. These special alignment tools center the front or rear cover when it is installed. Choose from three styles of these alignment tools. Plastic construction with O-rings. Made in the USA.
Note: Apply motor oil to O-Rings on tool - helps to prevent damage to O-rings.

LSTC1 tool is slightly more accurate than the LSTC2 tool since the rubber seal in the cover is a little more flexible.
