Hi I am new here nice to see others with similar problems. I have an 05 supercrew 5.4 litre with 109k and recently took to dealer for recall and had them tune up and check hesitation in transmission and heat blowing luke warm. Couple days after I got truck back it was very hard starting and blowing white smoke took it right to dealer and they found stuck open injector. They replaced that and the cat converter under extended warranty and changed oil. Ever since then I noticed a tapping passenger side of engine so I changed oil again but noise did not go away. Tonight on my way home the tapping turned into rapping and dropped a cylinder had it towed to my mechanic . I think I threw a rod. Will find out Tomorrow. Anyone know if this could have been caused by stuck injector three weeks later?

 

What does "dropped a cylinder" mean. Something fell into the cylinder ?

 

only running on 7cylinders

 

Yes - hydrolock.

 

Which ones ?

 

Sounds to me as if there was a bent rod from the hydrolock caused by the leaking injector. They failed to catch it.

The other possibility is that a second injector started leaking which caused a new hydrolock situation, but my suspicion is the above .

 

Bingo, we have a winner! (well, maybe more than one)

 

Well, I was leading up to that..

Spoilers.

 

Sounds right to me. Thank you for all your expert help. Have not heard back from dealer yet but I will keep you posted. Thanks again great site!
