What a day!! 2014 Ford Flex 3.5L/6F35 with 112,000 miles, Has Cam-Crank Correlation DTC's P0016 & P0019. All 4 cams are 10-16° Retarded but all 4 are within +/- 1° of each other which ruled out chain stretch. 16° isn't enough to say it jumped time either.
Called the customer & advised that the Timing Cover & Primary Timing set need pulled to investigate the timing error. Also let him know that the water pump puked a little coolant out the weep passage.
He was not happy to say the least as he had the Water Pump & Timing Chain done in December of last year at a independent garage that has since went out of business.
Got it tore down, Didn't see anything obvious & counted the Links just to verify (Bank 2 Primary Cam Link to Crank Link is 35 Links).
Removed the Priming Chain & found that the Crank Gear has been rattling around on it's dowel pin which wore the Dowel quite a bit, But also the Crankshaft.
No way the Balancer was seated or torqued down properly, But I didn't take note of how tight the bolt was upon disassembly. Though the drive belt is worn.
I dread having to call customers with stuff like this, He was trying to do the right thing by having the WP changed before it caused issues just to have a hack screw it up.
It needs a engine, Worked up a quote with a used engine & a new OE Water Pump.
Customer can't afford to put an engine in it.
We came to an agreement that I would try to restore crank timing & try to retain it by torqueing the balancer bolt properly using a new Dowel Pin & Crank Gear.
A new Dowel actually has some press fit & is standing straight.
Put it all back together using OE Ford Crank Gear, Water Pump, Primary Guides, & Primary Tensioner. Had to use a Melling Primary Chain as Ford ones are on backorder.
Cams are now Half a Degree Advanced @ Idle (Phasers locked), And held through some WOT runs to redline.
