Shynon 7,435 #1 Posted February 16, 2015 I have a Kohler K301 10hp block (new never assembled), yes it is a 10. It has a hole for a screw in dipstick that is not threaded and it also has a hole on the side for a bolt on tube style dipstick. My question is there a plug available for the top hole? Or should I push a tube in the top hole and then make a plate to cover the side hole? Hope this makes senses. Tom Share this post Link to post Share on other sites
TT-(Moderator) 1,128 #2 Posted February 16, 2015 You should be able to find a core (freeze) plug to fit the top hole. Dorman seems to be a popular supplier and many auto parts stores carry that brand.
