Hey guys, a few months ago I had my truck into the shop to fix a timing chain rattle that was heard all the time between 2500-3000 RPM. Ford had replaced the primary timing chain tensioner to no avail then they found out that the balance shaft tensioner and guide grenaded. After all that the engine is nice and quiet once again. But now, every time I let the truck sit over night or a prolonged amount of time I get a nasty rattling noise only on startup which lasts about 1-2 seconds then goes completely silent. If I turn the car off and back on there is no noise, not even after leaving the car sit for an hour. Is there anything that I should be worried about or is it just a characteristic of this motor with the oil pressure sensitive tensioners?
If there is a problem I would like to get it addressed before winter (truck is in storage until then). Any info would be appreciated.
