Hye guys, got a couple questions for you. Well the 3.1 in my cav is going to die any week now, I lost the rings on the 2nd cylinder but I still have to drive the car like this because I can't afford the down time of not having a car. So needless to say the engine is beating it's self to death. I have a spare 2.8 engine with about 260,000km on it and it has bad oil seals I think because after it runs for ~30 minutes the oil presure drops off. So to my question, is it worth rebuilding the 2.8 with a 3400 top end and what would I have to do to the engine to make that 2.8 a 3.1? Or is it even worth rebuilding at all, should I just buy an already built motor with a 3400 and drop that in instead? Hope this post wasn't to confusing I am kinda in a rush right now.
