Greetings all!! I sourced a new dipstick guide but I never put it in cause I'm still unsure if this is the correct length. http://www.ferrarichat.com/forum/142399368-post22.html The reason why I am weary is cause this guide did not fit freely in the factory union. I would have to swap out the union with a replacement (fits on the sump and tube side) for the guide to slide in properly. This guide I have appears to reach the bottom of the sump/at the cover. Is this correct?? Thanks! Image Unavailable, Please Login
I have no idea where mine is right now and that's not good. But if you were to put that tube against the bottom of the dipstick tube with the dipstick blade inserted fully, and the markings on the blade are beyond the tube it should be fine. The short tube is to guide the blade past the baffle in the pan
This is DEF not happening. The blade is maybe 2" MAX passed the end of the union. This dipstick guide reaches the bottom of the sump. So-- I DEF need someone to tell me how long the guide needs to be... PLEASE!!
It's not a requirement that the dipstick blade protrude past the end of the guide tube as the oil level inside the guide tube will be the same as in the rest of the wet sump (in fact, that's the design idea - any sloshing, if present, in the main sump area will not change the oil level inside the guide tube). It is important that the bottom end of the guide tube be open enough that oil can flow up into it. Not the greatest picture quality, but this scan of the Mondial 2V lubrication system shows the oil level in the sump (the red) is up to the bottom of the fitting so having the dipstick extend a couple of inches beyond that seem about rightish: Image Unavailable, Please Login
+1 -- your photo is excellent useful corroborating information. It's really a clever design (that probably some Greek dude originally figured out ) as the oil level in the tube is proportional to the pressure at the bottom end of the tube which is constant and proportional to the amount of oil in the sump regardless of how much the top surface of the oil is wobbling around = gives a much more consistent reading on the dipstick blade than just sticking the dipstick blade into an open ocean of liquid.
