My car has now begun to leak coolant slowly out from what i can tell is the weep hole along with a slight and random pinging from the timing chain ONLY at idle. I can only assume that the pump is about to go any minute and the rattle is from the pump bearings failing causing the chain to hit the side of the engine. I have decided not to drive the car any further in caution of the water pump dumping all of the coolant into my oil like what happened to this flex...

I just got a quote from Rad Air for $1500 before tax to change pump, tensioner, and chain. I think i ignored my timing chain rattle too long and it ended up messing up the water pump. What a dumb design to have the water pump inside the engine, they are only designed to last so long.... Thankfully i caught this right away since i dont have the bottom engine skirt and cover on until the winter in case of leaks like this. Thankfully i see no coolant on the dipstick and no oil in the coolant resovoir.
I would like to warn everyone with the start up rattle that you should get it fixed ASAP and not wait too long like me. I saw a post on here from last year with this happening to someone's SHO here is the link

Ah, thought we had this issue licked :( Does rear its ugly head time to time on the Cyclone engines as well, though there is no preceding rattle/warning.
I didnt think the water pumps had weeps holes like the old ones and i dont think you can see it anyway because its in the timing case.
The rattle i think is just the chain hitting the guides and fords have been doing this for 20 years lol
Not my pic but I saved this awhile back. It shows the pump at the bottom of the chain "v"

Here is a video how to change it on a flex if anyone wants to try this job themselves.

I just wanted to start this thread since there will most likely be more and more vehicles with this problem as many ecoboost 2010+ are just now getting over 100,000 miles.
