      2008 3.2 missing core plug

      Noticed a pool of oil under my car the other day. Turns out the "core plug" or sealing plug, whatever its called, is missing. This is the plug that covers the end of the crankshaft on the passenger side.

      I've located the part itself, but have searched all over and cant seem to find any information on fixing this. Is this part serviceable from outside of the engine? It looks as if it just needs pressed into place but I've tried that and it just pops back out. Is there something supposed to hold it in place or am I going about this entirely the wrong way?

      You probably need a new plug if you can't get this one reseated. These covers aren't super easy to press in. Access should be quite good from the passenger wheel well.

      So it does just need pressed in? I ask again because there is a bolt hole right next to this. Had me thinking there was another part missing.

      I keep trying to seat this thing and it just keeps popping out after a few seconds of starting the car. It's a new part, not like I'm reusing the old one.

      Pictures? Part number?
      If it's anything like the "freeze" plugs on the older engines, it's set with a little sealant and two hammers. I had a quick look at on engine parts diagrams, and see no end plugs for the crankshaft. Transmission, maybe?
      If you verify the part, we can advise on proper installation.

      It just presses in. Put some oil or grease on it first.

      Part #30637986 Sealing Plug

      I've already replaced my pcv. This plug keeps getting blown out a few seconds after starting the car. I'm not sure if I'm just not seating it right or if theres just too much crank pressure still or what's causing it.

      Or the simple fact I havent used any sealant on it.

      No sealant is used. I'd run a cylinder leakage test to see how much leakage is going past the rings.
