What do I put on sealing rubbers when I assemble the engine? do I just leave them dry ?

1993 Mazda RX7 2RTR-1308cc 80
Vehicle Level Engine, Cooling and Exhaust Engine Cylinder Block Assembly Service and Repair Assembly Front Housing


Front Housing
Notes

Mount the front housing on engine stand.
Position thrust plate with chamfer facing toward front housing, then install needle bearing and plate, torquing to specification.
Apply petroleum jelly to new outer and inner sealing rubbers.
Install outer sealing rubber so that white paint faces side wall in groove.
Install inner sealing rubber so that blue paint faces outer wall in groove and the seam is properly placed.
Ensure inner and outer sealing rubbers are not twisted.
Apply engine oil to contact surfaces, stationary gear and main bearing. Do not apply engine oil to sealing rubber.

So according to Mazda I apply vaseline to Sealing rubbers? Any tips/ tricks would be helpful!

First overhaul on a rotary. Still a couple things I'm confused about like:

Install outer sealing rubber so that white paint faces side wall in groove.
Install inner sealing rubber so that blue paint faces outer wall in groove .

Side ... outer... lol Which way is in or out?

It will run again... working on cars now for 10 years. Started this project as a challenge now it has just turned out to be work. Waiting on customer to get new rotor milled to 3mm
then I will begin to reassemble the block.

I went in to work yesterday and my other cust with a FD totaled it out Thurs night. He was merging when boost came in and spun out and knocked over a lamp pole. Now we're back down to one car in the area! The red one took a serious hit in the right rear and the rest of the car is ok. Parts may be for sale soon! lol

There was a thread here a couple days ago about guys using hylomar instead of petroleum jelly. Search for that.
