Replacing a blown 5.7 Liter Hemi

How long before the junk yard motor goes ? There's no easy answer to your problem , even an identical engine would probably be a P.I.T.A.

Get a second opinion from a reputable independent shop. I bet they can do the job for half the price the Dealer wants and you can get a freshly rebuilt crate engine with a warranty. Another thing to consider is the vehicle is 7 years old now. How much longer do you plan on keeping it? How many miles are on the vehicle? The rest of the vehicle, (transmission, accessories, etc.) all have that much wear on them. Is it really worth replacing the engine? It may be, or it may be better to replace the vehicle. Hope that helps! Jim
