Unless you're getting a really good deal, I'd look into getting a lower mileage engine.Bullitt said:I just wanted to get some feedback on the best ideas for this situation. My 1.6 in my 94 Sentra XE cracked the block (aka new engine.) 1st cylinder locked up and cracked the block just above the oil pan. It had 183k miles on it. I have connections to another 1.6 with 145k miles on it. I know that im gonna use that engine, but i have no idea of how well it was taken care of. I don't have the money for an all over rebuild, and i plan on replacing the timing chain before i drop it in mine. What are some other things I should do while i have it sitting on the workbench? Thanks in advance.
I'd look at, and replace if needed, all the gaskets/seals(front main seal, rear main seal, valve cover gasket) and the timing chains/tensioners.
I'd also recommend taking off the oil pan, cleaning it and put on a new gasket(using liquid gasket). This can also help you to tell what kind of condition the engine is in. I found a piece of metal in an engine I got once, which I was able to trace to the timing chain cover(the timing chain was eating into the cover b/c the tensioner was bad).
Also the other things 91sentra listed, myself I wouldn't bother with the head gasket unless you suspect it's bad.
