Thanks for clearing that up Vince.....

Did you take any pics when you were swapping them out? Like he said, the pump cover or body is probably damaged.

 

stock 4l60e should be fine behind that blown 408 anyways.

 

This is really starting to **** me off. I just finished swapping the pumps and putting the PB trans back in with the stock pump. When I went to fill it with fluid I get a steady drip coming from the inspection holes. Interestingly, the drip does not increase when the engine is idling (and therefor pump is spinning). I have starting taking it out again, but what do you think is the problem? All of the O-rings were on the bolts, and the converter seal, front seal, and pump seal were fine. Should there be a large plastic seal on the outside of the pump? The stock trans had one while the PB trans did not...

Also, I have the PB pump apart on my table and I can not find any damage at all. Only odd thing is the big race the rotor sits in is off center a little, like the spring is pushing it too far.

 

The slide is suppose to be off center. That is how it is able to adjust line pressure.

It's hard to tell from the pics, but it does look like there is some damage on both the cover and body. This is an oil pump with tight tolerances, so the smallest nick can cause it to bind.

 

I took it to a local trans shop today and the guy played with it for about 30 minutes and couldnt find anything wrong with it or any damage otherwise. I brought it back and after I took the PB trans out again, I switched pumps and was able to fully seat the converter this time. Im almost done putting it back in so hopefully I will be driving again tomorrow without issues...

Also got my 2.8" pulley for my blower today

 

Glad you got it worked out.

 

I havent actually driven yet, but im hopeful

 

Finished installing it today....forgot to plug in the trans so the starter didnt work

but after that I drove it around and all is good

thanks for all the help guys

 

I'm glad to hear your built trans is back in the truck & working. Now CRANK UP the BOOST!!

I'm really interested to see how your combo works.

 

The issue with your leak was because there are two different front covers with different style seals. With each of these pump covers the case changes depending on which style is the correct one to use. You basically had a mismatch if I had to guess.

I edited the pic's from above. In the pic's below I see a couple things that stand out to me. Vince



Between the two arrows this is the area that the pump vane was sitting when the rotor broke during the install. Where the arrows area is where the rotor dimpled the pump when it broke.
