Hey guys, I tried the search but no luck. How long to most 4.6's last before they start having serious problems? I'm looking at a 99GT with 200,000kms (125,000 miles) on it. With this mileage would I be looking at any serious problems in the near future? The guy did say he has receipts for all the routine maitenance.

 

Longer than the owner....... If a car is well maintained it can last 200k. I had 100k on my NPI motor and and had even and full cylinder pressure across the board.

On "my own" car I would put a s/c on at 100+k and not think twice.

 

Depends on how its driven. I know of motors w/ 300K plus on them.

 

i would look around some more for a lower mileage car as not much difference in cost between a car with 80K versus 120K....

 

You just had to 100k up me didn't you! Schmuck!

 

Well its the cheapest 99gt Ive seen for sale. Iven been looking on craigslist for a month now, and this one just popped up. Im gonna go check it out later tonight. He said it runs great. So we'll see..

 

there's people on this forum that have boosted/juiced 4.6s with well over 100k miles with no problem. they can last awhile as long as you take care of them. unlike a lot of 5.0s that can be beat on and still run

 

Mine has 123k on it and runs like a champ! I wouldnt worry about buying one with that mileage if he has receipts for all the maintenance. (thats why I got mine, he had documentation for oil changes at like every 2900) Good luck man!

 

mine has 142K no leaks.... i have had a few COP go bad.. right now it's skipping but i don't think it's anything major.. prior to that ran like a champ

i beat the crap out of mine everyday since i bought with 104K

 

Same here, 144k on my 2000 auto and hasn't missed a beat! I did have to put in a new trans 10k ago.
