Has my Hpop been replaced already

[Blowman]

I have an early 2003 with a 6.0 and I am tearing a few things apart to fix an oil leak. When I took the Hpop cover off I noticed that there was some silicon used on the back of the gasket to hold it in place on two spots. Is this something that is done at factory or is this a sign that someone has been under the Hpop cover before?

Could of been replaced, hard telling.

But....the silicon is something that was/is used from ford. It helps make a better seal where the block meets the rear cover.

It was only in two locations and looked like it was just a dab at both. Was thinking maybe someone used it to hold gasket in place during installation.

there is only a dab used on each side where the block meets the back cover. If you look close there is a seam were the silicon was/is used. The purpose is because the gasket sometimes doesn't seal as well as they like it to over that seam, and with out it it could leak at the seam.

The silicon in that spot is from the factory. It is sealing the back cover/block/HPOP cover. You are supposed to run a razor knife around the HPOP cover in that area before you take the HPOP cover off so that you don't hose up the seal between the back cover and the block. If the back cover seal gets messed up the only way to reseal it is to pull the engine (or so I have been told). Hopefull you didn't disturnb the back cover seal. When reassembling, be sure to put a dab of RTV in the same spots when you put the cover back on, otherwise you will have a leak forever...
