this thing (06 mgm) clattering for maybe a second on a cold start drove me crazy and i almost spent $3000 to get the timing components replaced only to figure out it's a non-issue all you have to do is put in a better oil filter and it happens less often, now it only does it maybe half the time, and if it does it's usually for like a half second, and it's even quieter when it doeshave you ever almost spent used car price on something that wasn't necessary
>>28110622is it coming from inside the engine or outside. mine made a clattering noise and it was the belt tensioner, 5 minute fix.
>>28110622I used to own a ‘03 Grand Marquis, and also an ‘03 Town Car. Both I sold long ago, and I miss them and wish I still had them. The cold start up rattle on both drove me crazy. A friend of mine started using Royal Purple in his ‘05 Crown Vic and claimed it completely stopped the rattle. It was painful to pay the price for it, but he was right. I ran my Town Car on it for six years, it never happened again after Royal Purple.
>>28111497>>28111535yeah it's the timing chain tensioner apparently. it's like a 1-2 second noise only on cold starts. apparently they take a second to build oil pressure. it drives me crazy because i'm a paranoid obsessive autist but reading all the forums it seems like most people live with it and nothing ever happens
>>28111535also isn't royal purple like 40 bucks
>>28111553>>28111555Ford said, as best I can remember from the time that it was normal, and causing no damage to the engine. I think I’m only car autistic because I was raised in the car industry by a car dad, I never believed that it was causing no unnecessary wear. I still use Royal Purple in my ‘16 F150 5.0 and it costs $10-12 dollars per quart. I use Mobil 1 in my wife’s ‘14 Acura, and my ‘08 VW. I use Mobil 1 oil filters on all our vehicles.

>>2811164103 model year had horrible quality control for basically every component
>>28111698First I've heard of this. It's not like the engine was significantly different than the year before, other than a few small things. 03-04 are the best model years to own. You get the major chassis update, but still have a cable connecting the pedal to throttle body like god intended.
>>28110622>06 mgmi have one. been pretty reliable, had a pressure switch and fan fail but nothing too serious
