Question about 2002 Ford Explorer

1 Answer

I took my 02 spt trac to Ford for noise I was hearing from the engine when I press on the gas pedal. I was informed that it is the timing chain. My question is, did something caused the timing chain to make that noise or does all of them go bad? Also, my extended warranty dpmnt would only cover the cost if it's broken or something else is broken which caused it to go bad. Should I pay for the mechanics to take apart the engine so the adjuster to take a look at it?

Timing chains stretch with age and when they do they start "slapping" timing case. If your extended warranty people were intelligent they would cover the replacement instead of waiting till it explodes and destroys a ton of other parts.

Ford sport trac, 4.0 dry start , and then continue ticking sound ,ive been told timimg chain


how many miles on the vehicle? does the noise quieten down when the engine RPMs come up? timing chain is very likely if you have over 150,000 miles. lifter noise is a more common problem. the lifters will tend to quieten down as the RPMs come up due to more oil pressure.

Loud Knocking when pressing on gas pedal


What you are describing sounds like you have an engine bearing failing. Do not drive it 'till you have it diagnosed and repaired (most times though it's too late when you hear it.)..... Outside chance it could be the trans flex plate but I doubt it.

2001 Ford Sport Trac - Front & Rear Timing Chains


The rear timing chain (or "cassette" as it's called in Ford lingo) is the chain that drives bank #1 (passenger side) cam. The front timing chain drives bank #2 (driver side) cam. There is a also a primary "jackshaft" chain that is driven by the crankshaft in order to enable both banks to be driven through a common shaft. The reason for this peculiar layout is because this engine is a "derivative" of the 4.0L OHV V6 engine it replaces. Ford simply installed a dummy shaft in place of where the camshaft used to reside on the original OHV engines. But above all else, the job you describe SHOULD NOT be carried out by anyone unfamiliar with this particular engine. There are NO timing marks on any of the drive sprockets, nor are they key to their corresponding shafts. To time this particular engine requires use of FIVE dedicated Ford/Rotunda tools that hold all relevant parts in proper position. Failing to carry this procedure out correctly, will result in the bending of ALL valves with 100% certainty!!! Therefore, it is best left to a Ford dealer technician to carry out. If you would like more information regarding diagrams, TSBs, and procedures with detailed illustrations, please e-mail me directly with your FULL Yahoo e-mail address so I can attach PDF files. Hope this helps.
