Default bought a GC

guy had it posted as a 2000 GC and come to find out it is a 2001 GC. I have sourced a 2000 GC 4.0 motor for it as the one that is in it is toast.... #5 piston created lots of shrapnel.

my ?? is this.... what, if any differences from the 2000 GC 4.0 engine to a 2001 GC engine.... should it work fine??

thanks guys....

No difference between the 2000 and 2001 engines.

thanks guys.... just started to tear into it and i can't believe how clean the top end is...#5 piston took a crap and the pin scored the piston walls.... i maybe able to bore it 60 or maybe sleeve it.... anyone ever done one of these??? if so how was your outcome?

I would love to bore it if possible, if not then junk yard motor it is.... I took some pics with my phone and will upload them tomorrow...

long day at the plant getting greasy then coming home and getting greasy... time to chase the wife around the house....

thanks guys for all your input...cya tomorrow....

See that orange can on the side of the block that says "FRAM"? Change it to one that says "MOPAR" or "WIX" on it when you install the new engine.

The blocks are different between the 2000-01 XJ and WJ from what I understand.

Well it's out and headed to the machine shop. Junk yard motor with 90k on it is priced locally at $1075+tx. Machine shop master rebuild total bill is around $800 with a stepped up comp cam

Easy decision.

Top 2 bell housing bolts were a PIA. Until I removed the motor mount bolts and dropped the front down a bit. Then they came out no prob. Tranny pissed out enough fluid to make my garage floor look like OJ stopped by.

Exhaust mans looked very good and will be reused. I plan on new water pump, stat, idler, tensioner, and belt.

More pics and posts to follow.

Have a good one guys.

Well, got the motor in, and now it cranks but won't start. It did backfire through the intake a couple of times.

so... ? does the gray unit where the distributor would be call the timing?? could it be 180 out? It did spit and sputter a few times and the garage smelled like exhaust, but no fire... any help would be much appreciated.

thanks guys
