Hi guys as you can guess from my handle I'm predominantly a ford man, so any way "We" wanted a 4x4 & long story short found a nice looking 2001 Lorado 4.7 liter V8 on evil bay locally which is good as we are in Gladstone QLD ,& won it at a decent price of $4050.00 so far so good checked it out & all seemed good just had to replace rear torque arm bush for roadworthy (sweet) still all good . then driving it home aprox 30 km out & 5 km from home the check engine light comes on ( not so good) so checking gauges we nurse it home , seems to be running fine. when we get it home I check the oil , a little bit low no biggie , using a rag I release the pressure in radiator (lots of pressure not good) get the cap off & yep bubbles in the cooling system . So now I have a "new" jeep I cant drive till I rip the heads off , get them checked out & put back together YIPPIE!!!
