Razorback 1,032 #1 Posted November 20, 2019 (edited) I finally remembered to ask about this: My 1974 C160's dipstick tube does not fit tightly in the engine block (Kohler 16HP). Should there be maybe an O-ring just below the formed metal ring in the lower end of the tube? Edited November 20, 2019 by Razorback Share this post Link to post Share on other sites

ebinmaine 62,359 #3 Posted November 20, 2019 I seem to remember this coming up in the past but I have no recollection why. The dipstick tube and base on my Cinnamon Horse is pressed tightly together as it should be and there doesn't seem to be any way to separate them except maybe damage from a previous owner. If yours is able to be moved but still snug, perhaps some JB weld after a careful cleaning? Share this post Link to post Share on other sites
pfrederi 17,040 #4 Posted November 20, 2019 (edited) Interesting coincidence Monday I pulled the dip stick tube out of my 16hp K341. There was some residue that at first looked like a badly decomposed O ring. (there is no O ring and if you look at it an O ring would not help hold it in.) Turned out to be some epoxy that had oozed out from a previous repair attempt. The PO had used a center punch to put a bunch of divots in the tube to try to get it tighter and help the epoxy. Do not know how long it had lasted . i have had the motor for 5 or so years. I Put in some more punch marks but used Loctite anaerobic flange sealant (515) claims to not be bothered by oil. We will see how long it lasts.... Edited November 20, 2019 by pfrederi 1 Share this post Link to post Share on other sites

chip61 655 #7 Posted November 20, 2019 If not too loose I have had luck striking a surface with the corner of a file repeatedly-not as neat as knurling, but effective. 2 Share this post Link to post Share on other sites

AHS 1,405 #9 Posted November 20, 2019 My 73 14 hp has a thick o ring. Does yours look like this? @ebinmaine 1 Share this post Link to post Share on other sites

Razorback 1,032 #11 Posted November 20, 2019 Yes, the dipstick on mine is similar to yours. But, what I was trying to describe was the tube that the dipstick goes into, and specifically where the lower end of the tube goes into the block. Share this post Link to post Share on other sites
richmondred01 2,190 #12 Posted November 21, 2019 Where the steel tube goes into the aluminum housing? Share this post Link to post Share on other sites

richmondred01 2,190 #14 Posted November 21, 2019 No o ring. They are pressed in. Try to remove the tube from the aluminum casting. If so clean it and install with marine Tex. if you have issues contact me via pm. I have several in the shop. 1 Share this post Link to post Share on other sites
