Default Lifespan of the 4.6...

So i have a 1996 mustang gt, it will be hitting 140,000 miles soon..and I mean it runs like a champ, but deep down im wondering if i should start being leery. The car has just started to burn oil. Not alot, but it is buring it and when i first start it up in the morning it clicks/taps alittle bit but nothing loud. I mean by this time next year it will probally be between 146,000-150,000. So what about you guys..anyone else out there have a high mileage stang that can reassure my confidence haha

My 02 has 140k and still running strong. I'm about to install a Vortech v1. I'm not sure how long it's going to last after that.

My 01 has 184,000, uses no oil, leaks no fluid, has a light tap on cold startup....runs like a striped ape.

This is free-revving to 5K warm, and it loves it.

140K is not alot of miles on these motors. Remember this is the same motor in Police and Taxi cars. I well maintained 4.6 will last a long time

Ive seen MArk8's, Towncars, and stangs with well over 300K N/A with good care. Not saying some repairs hadnt occurred...but the engines were still running good.

I wouldve never guessed your 02 had 140,000 miles from looking at the picture in your sig.

But thanks for the input guys..i think i should be good for awhile haha

The 4.6 is a really reliable motor! Obviously after 140k or so, you will probably need to do some minor preventative maintenance (gaskets, etc.), but as for anything major? As long as she was taken care of, I wouldn't worry

I have 147k on my 97. Runs like new. I have heard of these motors going over 450k. A lot of them make a little noise on start up. Some have done it since new. It's the nature of the beast.
