Mike 57 Posted October 9, 2014 Share Posted October 9, 2014 Yep it is possible, are you sure it is the main seal? Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted October 9, 2014 Share Posted October 9, 2014 I was going to say the same thing, the oil pan could be the issue Quote Link to comment Share on other sites More sharing options...
Murphy Posted October 9, 2014 Share Posted October 9, 2014 I thought I had the same issue, rear main seal........turns out it was a combination of the oilpan gasket and the distributor gasket! Quote Link to comment Share on other sites More sharing options...
Rock Posted October 9, 2014 Share Posted October 9, 2014 I thought mine was leaking too. Turned out to be a small chunk of cork from the old valve cover gasket wasn't completly removed causing oil to run down the rear of the motor......I was a happy camper when I found that problem.

waupachino Posted October 10, 2014 Share Posted October 10, 2014 Are you sure it's the o-ring leaking and not the gear seal itself inside the Bullet? Mine was leaking due to the gear seal, and I just replaced the whole Bullet from here. They also have just the o-ring.

bigscaht Posted October 11, 2014 Author Share Posted October 11, 2014 actually im not sure..wasnt aware ou could buy the whole bullet like that..that might just be the way to go...thanks for that link Quote Link to comment Share on other sites More sharing options...
bigscaht Posted October 11, 2014 Author Share Posted October 11, 2014 man that site was cool..ordered the whole bullet only 9 bucks....cool beans Quote Link to comment Share on other sites More sharing options...
waupachino Posted October 13, 2014 Share Posted October 13, 2014 Yes it is a cool site. Just a heads up, have an Oil pan ready when you pull the old Bullet out. I made the mistake of not thinking much Transmission fluid would come out and flooded the Garage floor. Oops. Quote Link to comment Share on other sites More sharing options...

Brent C Posted October 15, 2015 Share Posted October 15, 2015 I am about to do the same to my Monte. It is a 1970 with a 350/350TH and a 2.73 open rear. I am running 235 60 R15 tires. I figure since I am changing the bullett out I should put a new speedometer gear in to correct the speedometer. I am having a problem finding the new color and number of teeth I need for the new gear. All of the websites ask for the old color/teeth info. Is there a way to determine what should be in there from the factory without removing the original? I am trying to get it completed all at the same time without making a mess of the garage floor. Any help is greatly appreciated. Brent Quote Link to comment Share on other sites More sharing options...
Murphy Posted October 15, 2015 Share Posted October 15, 2015 Brent, the link here has great info for determining driven gears and color combinations.... http://chevelleengineer.home.comcast.net/~chevelleengineer/speedo.htm You really should pull your driven gear to verify the color so you know which gear you need to order. 1 Quote Link to comment Share on other sites More sharing options...
