Working on my daughters 2005 F150 2x4 with the 5.4l 24v. Driving down the freeway lost oil pressure, sounds like someone thru silver ware in the disposal. Torn down and replaced oil pump. Cleaned pump pickup of gunk and plastic from 2 timing chains. This was the 2nd time. Cost 1500.00 , two years ago so since I'm retired and have tools I'll try. Lined up all the marks and chains per videos on here and no start. Spark, fuel and air no run means I don't have timing wrong?. Torn down to find marks way off and phasers loose. I didn't loosen them. So can I use the old phasers and buy new bolts and torque to spec. With 90° plus or do I have to buy new phasers?? Thanks in advance...

 

i would replace them. the new ones will come with new torque to yield bolts. loss of oil pressure could have done damage you cant see without taking them apart. make sure to get the latest version from motorcraft. and stay away from dorman phasers

 

I thank you pop top..I've got 600.00 in parts and now have read that there could be valve damage? $220.00ea. Phaser?.. Wonder if I should buy new bolts to try and start and if it runs smooth at idol invest in phasers then?
