Jasper 4.6

[67mustang97]

I had a Jasper remanufactured long block installed in my 02 GT this spring. I took it easy on the car for the first 500 miles like they recommend. 3700 miles later they have to replace it due to severe oil consumption! The car is fine while you drive it but if you let it idle for a few minutes it begins to bellow smoke. I can't figure out why it only smokes when it idles has anybody had this problem, or know why it happens? Jasper is standing behind their engine 100%.

We dealt with jasper remans at the dealer I worked at, if a customer was out of warranty and wanted a slightly lower cost option.

Very good company to deal with from my experience, they stand behind their warranty - but also from my experience, I've gotten remans where I will recheck all visible bolts on the long block (cylinder head bolts/etc) to be sure they torqued everything properly.

It could be they had a fluke, or a block that was damaged, which ended up destroying a piston ring over time, or could even be valve stem seals/something less obvious

It could also be smoking when you're driving it - just kinda hard to tell in a rear view mirror
