Bad sound from engine
Spark Plug Blown Out Just they way it happens when the plugs blow out. You hear the ticking and then they blow. If the coil packs are still bolted down then it will hold the plug in place. I had one blow out while towing my race car from Philadelphia to Palm Beach, Florida and had make the...- tatios

Head Gasket Blown on 5.4 What Performance Mods
One of the the reasons I pulled the motor was so I could use ARP head studs. I am not going to use factory stretch bolts. I see too many head gasket failures on engines that are run for long periods with heavy loads. I run 24hr endurance races and stretch head bolts are the Achilles heel of...- tatios

Head Gasket Blown on 5.4 What Performance Mods
PI in Early Expedition I am hoping to find someone running the combination. I will have to do the calculations on the compression to see what the combination yields. The pistons sit in the hole which I normally don't like and if the combustion chambers are smaller on the PI then the pistons...- tatios

Head Gasket Blown on 5.4 What Performance Mods
I have a 97 Expedition with a blown head gasket. I have pulled the engine. What a PITA... I am a professional wrench but not on Fords. I want to increase the performance of this vehicle which I use primarily to tow a 22ft enclosed car trailer. It has the trailer towing package with the 5.4...- tatios
