Guys,

can someone please link me to the ultimate timing chain stretch forum topic? I have a 2014 Ecoboost and the dealer is thinking timing chain, i want to give them a list of items to fix but i cant find the original thread with the TSB (the right one) that tells you what all to change, looks lik ethey are doing gasket, tensioner, silicone and thats about it!

DL3Z 6584 C (gasket) *1
BL3Z 6D256 C (tensioner) *1
TA 357 (sealant - Silicone) *1
ZC 30 A (Remover Silicone) *1
ZC 31 B (Cleaner - Metal Surface) *1
CVC 13 G (Anti-Freeze) *1
CXO 5W30 BSP (Motocraft SAE 5W30) * 6
ENOIL (Enviro) * 6


I need to find that thread quick and cant find it anywhere...thanks guys!

 

Look for Ford Tech Makuloco on YouTube.
This is a reminder list I made from one of his several 3.5l timing chain videos. (For when mine is due).

Parts

Valve cover gaskets

VCT solinoid seals?

Spark plug tube seals?

Hp pump torque to yield bolts

Phaser torque to yield bolts

New Crankshaft bolt

Top coolant tube O-rings

Water pump?

Water pump gaskets/seals

Thermostat? & housing seals

Belts

Belt tensioner

Y tube O-rings

Heater hose O-rings

Front cover seals

Timing chains

Main tensioner

4 phasers

Chain guides

Hp fuel pump O-ring

Hp fuel pump?

Melling oil pump?

 

Last three relevant TSBs attached. Mine has been trouble free in the 50K miles since fixed. If your dealer can't even find the TSB, I'd find another dealer.

 

Thanks! Those part numbers will be useful.

 

Just had a look at the torn down engine and currently phasers dont appear to be an issue and are currently in ok working order (cant confirm how much life yet) - they are tearing down the front cover to the cam sprocket to see if the pin has sheared off causing my chain stretch (it is definitely stretched with play when moving by hand). Im wondering if i should change my phasers ... costs are quickly climbing and its something i could do, but with my limited budget i dont know if i should complete it.



side note, you can change the coolant fittings on the turbo without removing the turbo right...a pain i bet, but i remember removing the hardlines prior to removing the turbo, then removing from the turbo when the turbo was free - i feel like i couldve gotten in there, pushed the hardlines to the side and changed just the fittings? for the fittings and hard lines etc. without manifold its about a 1k job (canadian, probably $20 USD lol - joking probably ~700 usd), pretty sure I can do it myself but wanted to ask here

 

oooh chain was stretched close to 1/2" ... new phasers, solenoids, chain, tensioner, guides seals etc. going in...now to just fix my coolant fittings at the passenger turbo lol

 

That list of new parts sounds better to me than the initial one.

How many miles where on the timing set being replaced?

 

93K, the last half or last 1/3 of those miles i was changing oil every 3k miles ... man this engine has issues - i think its fuel dilution of the oil that is the root cause FYI
