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...
https://www.fordflex.net/forums/viewtopic.php?f=7&t=14512I 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
