F150Torqued

^^^^^^^^^^

FORGET CAM LOBES at this point. If you removed the old phaser ----- hope you marked the chain links where the old phaser timing mark was AND YOU BEST put the new phaser back _EXACTLY_ where the old one was. If it wasn't bending valves THEN, it won't be now. But if you move the engine at all - you are fixing to foobar everything and then all bets are off.

I marked the chain and put everything back to the same thing it just scares me that the phaser broke while it was changing its timing because i had no ticks, rattles, or any noise at all from the phasers or any timing components, it literally happened while i was cruising home from work one cold night.

At least drop the oil pan and look for plastic and the pin . Plastic means a full timing job and clean shards out of oil pu . But getting back to your path you would turn the crankshaft two full turns by hand clock wise if you think its back together right . No clunk means its not hitting piston to valve .Do not use starter use crank bolt with socket .You can pull plugs to make it easier . Me I would do full timing job . How many miles etc .
Turn engine by hand until the other phaser has three tines up the l should be immedaily behind the middle finger . You need the 360hv and it could be you have two aftermarket junk phasers . If oil system clogged/broken guides you are going to get more trrouble . Send that picture .

I agree with everything others are saying concerning what sounds like you are short cutting this repair. But to address your specific above comments, it is quiet unusual for these engines to skip a tooth on the chain (provided you have no other associated noises. ie: chain slap, marbles in a coffee can on startup, etc). You seem to indicate that wasn't the case. I think your popping in the manifold was the natural result of the following: The 5th finger on the phaser is attached to the half of the phaser attached to the camshaft. It functions to let the PCM know when the valves are 'closed' so it can fire plugs _WITHOUT_ a valve still slightly opened. With the broken rivits - allowing it to slip and PCM's tdc reference on that bank is all screwed up, the cam is NOT where PCM thinks it is and it commands spark before valves are all closed tightly. I do not think your popping was result of chain jumping time.

Truck has right at 174k I'm not trying to shortcut a timing job at all i watched many videos and listened to trucks of people i work with that had phaser problems and chain slap and then i bought the truck because i heard none of the noises and test drove it for a few days. I had it 3 months and it did its thing and not one time has it given me any trouble out of timing, i wasn't running wot on it or anything, changed the oil twice in the first 3 months with 5w-30. It just doesn't make any sense how it can catastrophically fail like that without giving any of the warning signs at all. I'm not trying to shortcut a repair honestly. The truck was my daily driver vehicle, while we still had my wife's explorer and Audi A3 for spare. I just want it fixed. I really don't mind pulling the whole front of the motor off, the work doesn't bother me. As well as taking my time , I'm just tired of hearing the wife telling me I bought a crap truck and having a yard ornament. What do you think was the result of all this is then F150Torqued?

What ever you may chose keep us in the loop .

I will, I might try pulling the pan in the next few days as well as doing what you suggested and slowly turning the crank over if i wasnt at work i would upload a picture of the broke phaser after i pulled it off

Is it a Ford phaser or aftermarket? Check for the dorman insignia. Sounds like a PO slapped it together with the cheapest parts possible to sell it. If it’s a Dorman phaser, every timing part in that truck is suspect. Dormans are known for shearing their pins, Ford parts aren’t. They’ll knock for 50k miles without sheering.

edit: went back and looked at he photos, they’re definitely not new. Doesn’t mean they’re original, though.

It’s a Ford phaser you can see the FoMoCo on the final picture

And so it is. Mark it down for a somewhat rare outright failure of the Ford part.

That sucker is filthy, if it were my truck that cover would be off tomorrow. With as much varnish is on that, I wouldn’t trust anything else in there.
