Why does my engine rattle on cold start?
Dear Tim: It is not unusual to hear some engine when first starting on a cold start. The sound can either be from a hydraulic valve lifter, or piston-to-cylinder wall clearance. As the engine warms, the clearances change and get tighter and noises will usually disappear. The noise may not occur again for weeks.
Why is my f150 making a rattling noise?
While there are a variety of reasons your Ford F-150 is rattling, the most common 3 are the ball joints, struts or strut mount, or a problem with the sway bar links.
How much does it cost to replace a timing chain on a F-150?
The cost to replace the Ford F-150’s timing chain averages between $1,100 and $1,500, with most cost attributable to labor. However the F-150’s chain is designed to last the life of the vehicle, and remain maintenance free unless it breaks or the tensioner is stretched.
How long does it take to replace timing chain on 5.4 Triton?
Based on one popular labor guide, timing system replacement in 3V 5.4L Ford F-150 trucks requires 11.8 hours of labor. Having a thorough understanding of the timing and VVT systems in order to properly diagnose and repair engines the first time, avoiding that second 11.8 hour job, is crucial for automotive technicians.
Should a timing chain rattle on startup?
Timing chain rattle on start up is a common issue across all manufacturers. The reason timing chains can be noisy on start up is either the pressure in the oil charged tensioner is bleeding off, or there is extra slop in the chain system that the tensioner isn’t design to take up.
Is timing chain rattle on startup bad?
If the chain is rattling for 3 to 4 seconds at startup, it is NOT normal unless the oil has just been changed or the vehicle sits for an extended period of time (several weeks). If it is rattling that long of a period, I would recommend new guides and a tensioner.
How much does it cost to get a timing chain replaced?
For most cars, a timing chain replacement costs between $413 and $1040, or you can order the parts themselves for $88 and $245. It is a tricky repair though, so unless you’re particularly skilled it’s usually best left to a mechanic.

Does a Ford F150 have a timing belt or chain?
Despite the fact that Ford F150 Timing Chains are tougher than the timing belts made of rubber, they can still fail and be the cause of critical damage. The vehicle’s Ford F150 Timing Chain matches the motion of the crank shaft and piston position with the radial motion of the cam shaft .
Can a timing chain make noise?
Under normal conditions, the engine should have a consistent, smooth sound that indicates everything is running as it should. However, when the timing chain is loose, it may cause a vibration inside the motor and will be indicated by a rattling noise as the engine idles.
What does a loose timing chain sound like?
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. Such a noise will reveal a loose timing chain hitting the inside of the timing chain cover every time it rotates.
Why does the timing chain rattle in Minis?
The chain tensioner is inherently weak and has had several revisions from BMW over the years. A weak tensioner can cause your MINI to develop the dreaded cold start (death) rattle. This is where the chain is not under the correct amount of tension and is free to rattle around against the plastic chain guides.
