5.4 variable timing
Have many people had to replace the variable cam timing idler? This is a 5.4
04 with 23,000 miles. The timing chain is slaping the housing on cold start.
I am thankful it is under warranty. Hank Farmer

even with the idler broken it would be almost impossible for it to hit the cover. you are describing a known problem which has to do with the oil filter. which oil filter are you using. It must be a oil filter with a silicone ADBV if not after shutdown the oil returns to the pan and the galleries are dry and you are dry starting the engine each time. the noise is from no oil pressure going to the top end and causing premature wear.

variable timing
All service work has been performed by the ford dealership. They did install
a different oil filter on my first complaint. Now they say they will ivestigate
for idler failure saying they have had some problems with other 2004 models.
Thanks for your response.
