So the engine is out..
I am attaching photos. The leak is coming from the front of the motor. It appears my main seal # 8 bearing is dry, but under it is wet. But it is wet above the Intermediate shaft cover. Fan blowing it all around and coming from there? Thoughts? Thank you. ___________________________________ Hi there, A question for the esteemed who know more than I do! I am tackling oil leaks on my 2.7 six conversion. Today I changed out the driver side axle flange seal which was leak #1. Tomorrow or Wednesday I will tackle the Oil return tube seals. (Thank you Bruce for the nice set of spare tubes I will be using). Leak # 3 is likely my front main seal, behind the pulley. I am hoping it is not a leaky #8 bearing and is just the seal, but the oil is coming from that area and I won't know more till I get it apart. The question is: Can it be done with the engine mounted, and not require a drop? I have a non factory mount, likely the Mad Dog style mount that pivots. I know it is "easier" if the motor is out, but that is a whole other adventure... Thank you all. Robert |

99% sure it’s the number 8 o ring internal to the case and going down the seam. There was a retro fit kit that existed to repair that without splitting the case.

I did purchase Tom Amon's kit anticipating that, I just expected the main seal to be wet too and more of a mess. I am hesitant to pull a perfectly dry front seal that was clearly replaced when this motor was apart in it's life already. If it was oily etc, I'd yank it.
I didn't want to clean anything till I had some opinions on what I was looking at. I will investigate the "seam" under the seal a bit more and will for sure be pulling the intermediate shaft cover and cleaning, ensuring flatness and sealing it back up. I watched Kurt from Klassic Automotive training assemble a motor, he installs that seal dry with just the gasket. Mine is clearly sealed with a sealant, unknown if a Yamalube type that stays soft or a more solid one. Any builders out there know, install it dry or use a sealant such as aircraft Permatex? 99% sure it’s the number 8 o ring internal to the case and going down the seam. There was a retro fit kit that existed to repair that without splitting the case. |
