M-12 Dipstick measurment....

[Allure2sail]

Hi All:
The rubber bushing on the dipstick to check the oil has come loose and now I don't know if I'm getting a correct oil level reading. Can someone pull their dipstick out and measure from the end tip of the dipstick to the shoulder on the rubber bushing that limits how far into the block it will go. I put a pair of cable ties onthe stick itself to prevent the bushing from sliding further up the dip stick and giving me a false reading but its location was just a guess. I can not tell by looking at the dipstick where it was located from the factory, there are no tell tale marking where it (the bushing) use to be. I just changed the oil and I put in 1-1/2 quarts, which if my memory is correct gives me a full amount of oil for this engine. Thanks in advance for any help.

Second try...
Perhapps if someone has a manual for a m-12 they could tell me how much oil does a M-12 take with an oil filter and oil change. I have put in 1-1/2 quarts, but I don't trust the dipstick reading now. Sound right?

Bruce,  1.5 to 2.0 qts according to the manual.  If I can figure out how to attach it, I'll send the spec sheet from the manual to you.

Hi All:
The rubber bushing with a shoulder on it has slipped up on the dipstick so I no longer get a true reading on the engine oil level. I did at first put the 1-1/2 quarts in at the recent oil change but went back and put in the other 1/2 quart to be sure (manual calls for 1-1/2 to 2 quarts. Problem is you never get all the oil out with one of those pump up can suction devices, thus I really don't know how over filled the oil pan is. Overfilling can be just as dangerous as underfilling it. If the crankshaft can hit the oil as it spins it will whip the oil into a foam and the engine will lose lubrication because of the oil being aerated. So could someone please, please, please measure from the tip of the dipstick to the shoulder on the rubber bushing (which contols how far into the oil pan it goes).
