certanly does my friend
thanks again for the speedy responce mate

 

chances are your motor is fine but be canny with it for the first time try and hear if there is any knocking ect. before driving it

 

Just so's everyone knows,

one can empty an engine oil pan of oil and run the motor between 2500-4000rpm for a period of approx 20 miles before the bearings (crank/cam) will finally seize up, due to no further replenishment of the lubricant.

I have seen cars go further. funny, I saw some jackasses two months ago in some rice burning P.O.S. going down interstate 85 towards Atlanta (actually outside Raleigh-Durham.) and they were thugs in this car and just smoke everywhere going 90+ MPH, I followed for about 30 miles (safe back from the fumes they were emitting),.. weirdest part was no cops ever saw this or even were travelling on the northbound side, I mean this car was puttin out oil smoke like you would not believe, no idea before they passed me as to how long they had been drivin like that.

finally after 30 miles I saw the car just stop! dangerous as hell as other traffic was trying to stay clear of these freakin morons.

so, to be honest and having some experience with a blown engine as well (thats another story), your due diligence in only going a mile and probably at normal revs, did no damage at all to your jeep sir.

as said before the first time you drive it listen for knocking and what not but you should be fine only driving for that short distance

 

got and fitted the new pressure valve thingy re filled it with oil and after about 10 min of cranking [disconnected the coil lead so to get oil round the engine] it burst into life
no knocks nothing


someone was looking out for me that day
cheers chaps
