Hello, hopefully someone can shed some light on what I am missing. I got rid of a chrome oil pan on my flat head due to leakage and installed a steel one. I have the one piece front seal on my engine. When I reinstalled the pan I filled up the valley in the pan that meets the seal using The Right Stuff from Permatex as well as coated the bottom of the seal. I also put dabs of The Right Stuff in the areas where the cork gasket meets the seal. I did cut a fork style pattern into the cork so it would fit around the seal tightly. I'll be removing the pan for a third time because it is still leaking, not as much as the first time I tried but still leaking. What am I missing? Should I be leaving the valley in the pan where the seal sits empty of silicone so drain back can happen through that drain hole? Should I be using something other than The Right Stuff. I have tried calling a few of the flat head builders and the ones I've talked to have never used the one piece seal. Any help would be MUCH APPRECIATED... Thank you
Question is it leaking on the OD of the seal or the ID? if the pulley nose is worn in the seal area it may be leaking on the seal ID to pulley surface.
The motor has only about 3000 miles on it, being completely rebuilt in 2006. I'll have to take a closer look at things when I get it apart again.
I re-posted this question under the name 'Flat Head Oil Pan Help'...thinking it's much more specific to my problem. I've had a few replies but no definitive answers yet. Seems some people have no issues with the one piece, where others, like myself, do have problems. We'll see how this plays out. But thank you for the answers here so far. It's appreciated.
Norm, Just for the heck of it post your question on www.fordbarn.com with pictures. I bet you get results.
The one piece front seal is your problem. You should use the original rope type seal I find it works fine in the few hundred flatheads I have built including the ones running over 170 MPH.
