My oil pan on my 4.9L straight 6 is leaking. I went to Mid-Five auto parts store here in Livonia and they sold this to me:

Felpro/Oil Pan Gasket (OS34601R) | AutoZone.com

Per the Ford 96 service manual, it says to:
3. Apply black silicone rubber F4AZ-19562-B or equivalent to parting lines between rear main bearing cap and cylinder block, and between engine front cover and cylinder block.
4. Apply suitable pressure-sensitive adhesive to cylinder block flange and oil pan gasket.

However, the instructions for the aftermarket gasket say this:
IMPORTANT: This molded rubber silicone gasket must be installed DRY without any chemical adhesive.

So, which do I do? My thought is that if I were using the original Motorcraft gasket, then I should follow the instructions per the manual. But since this is an aftermarket gasket, I'm guessing the gasket manufacturer knows what is best. What do you all think?
Also, in instruction #3 above, it mentions "parting lines between rear main bearing cap and cylinder block, and between engine front cover and cylinder block." What does that mean? Are there indentations or lines that need to be filled with silicone to prevent leaks?

 

Right there says it all

3. Apply black silicone rubber F4AZ-19562-B or equivalent to parting lines between rear main bearing cap and cylinder block, and between engine front cover and cylinder block.

 

Brad - forgive my ignorance, but is the "parting line" the line where the front engine cover and engine block meet and the rear main bearing cap and engine block meet? Also, I take it then that you are saying to NOT apply the pressure sensitive adhesive in step #4?

 

I changed two of these oil pan gaskets on my '93 I6 and didn't use any sealer, but I used the silicone gaskets. One tip tie the gasket to the pan with four zip ties - one at each corner, to hold the gasket in place, then start the remaining bolts. Once the bolts are started, cut the zip ties and pull them out and start the last four bolts.

 

just 4 dots of RTV

One in each corner where the block meets the timing cover and the rear main. No other RTV anywhere else

 

OK. I have read on other websites and on youtube that this is the way to go. Thanks!
