Works great!
by Adam from Bowling Green, Kentucky on March 03, 2014
This seal kit isn't as hard to put in as you think, buy the spanner wrench, read a manual, and it's going to be just fine. I did the upper in 1.5 hours and it pressure tested perfect.

Missing seal
by Michael from Minnetrista, Minnesota on February 23, 2014
Either the picture for this product is misleading, or there was a piece missing from the order. The picture shows a plug with a gasket however, only the plug was sent (no gasket). Two emails to the customer service area regarding this went unanswered.

What's to say
by Scott from Chisholm, Minnesota on June 12, 2012
This does what it is supposed to do and that is stop the oil from coming out when in place and allow it to flow out when removed. Seems to work well!
