Need Mopar Chrysler Tech Help

I just did an 06 caravan 2.4 last week, i took it out the top, hood off and wiper cowl removed plus all accesssory brackets had to be off as well as the crank pulley and it was a tight fit cause i left the exhaust manifold on coming out, left that off dropping it in was no problem. I also did an 06 pt cruiser and that on i dropped out the bottom with trans attached.
for all who care the 06 2.4 in anything is known for thrust play in crankshaft, and the crank knocks the front seal out causing what most customers come in and say they have an oil leak, next thing they know they are getting a short block!
