2004 Ford F150 V8 Four Wheel Drive Automatic
I just did a timing chain, guide rails, and tensioners on my f150 5.4 lariot 2004. The front engine noise was a very distinct rattle at initial start up it is still there until the oil pressure builds then the rattle sound goes away. The tensioners do not seem to be holding oil pressure after the engine is shut off, they seem to be bleeding off, it takes about 20 min. Of sitting. Iis there a check valve or a bleedback valve that is faulty that could be causing the tensioner to bleed off its pressure. The old tensioners were spongy when I removed them, I don't think the new ones are performing any different.
have the same problem?
