when my 97 4.6 starts to use oil I change the PCV valve and the oil consumption drops back to less than 1/2 qt. in 4000 miles

 

Any dealer will say that, Ive heard of dealers telling people putting aftermarket exhaust on their trucks will void its warranty.

 

Well putting an aftermarket cat back exhaust WILL void your cat back warranty due to the fact that it's not there! Ford can/will only warranty ford parts.

 

I noticed the same on my 97 4.6. It seemed to be using some oil, I do have 203k on the truck. I have noticed now that since I changed the PCV valve that my consumption is way down.

 

I'd love to do a long trip like that.... Someday... I also want to see Custers Last Stand (somewhere in Montana..), Mt Rushmore (somewhere in one of the Dakotas.. South, I think...), Yellowstone (where ever the hell that is.... It like covers 3 states!) among many other landmarks in this great land of ours...

But, I'd need like a month or more to do it right! Hard enough to get a week off now.... I hate HAVING to work....

Someday jbrew, and I'll buy the first round!

First round , sounds good !! I'm about a stones throw away from Hell , That's Hell Michigan . I've gone to Hell quite a few times and have even been sent there on a few occasions - But yeah , if you think about heading up this way someday, let me know ..

 

I've been checking the oil more often since I posted this with no noticable consumption. It's always full. I was pretty hard on the truck that time. 4 1000+ mile trips in less than a month and lots of city driving too. I know, I shouldn't have gone 5000 miles between changes but I was busy. Thanks for the replies. I think it's ok now though.

 

Has anyone ever taken one of these motors apart????

FYI even if you drain the oil on a 45deg. hill there will still be almost a full qt left in the motor. I pulled my 4.6 and you would not believe the amount of oil still in the motor when I was taking it apart.

You filled up the qt bottles full so 4 full bottles probably = 5 qts + 1 still in the motor gives you a total of 6. Now considering you did not get EVERY last drop of oil from the drain pan into the qt bottles there is some and unless you have a filter splitter and cut it open you will never fully drain the filter. So we are now up to what about 6.5 qts accounted for.

As for warranty being voided you could run 10w30 in a mod motor and unless they could PROVE that is what blew blew/locked up your motor then Ford has to pay for it.

I had a friend snap his left axle at the drag strip, we trailered his car to the dealership, 3 days later they called him to come get it, free of charge under warranty. Now he had aftermarket rims and tires on the car, street tires but none the less not OEM Ford parts. He also had FRPP 4.10's in the rear that were not installed by Ford.


Go look up the Magnuson Moss act.

And as for 5w30 killing motors I would love to see some documented cases on that one. I know pleanty of guys using 5w30 in a car spec'ed out for 5w20and they are drag racing them all the time. Hell I run 5w30 in my Mach, daily driven, turns high 11's at the track and has not had one single problem yet.
