Just got my remanufactured block back. Ive got everything together except that I cant get the darn dipstick tube to go in!! I ordered a new one from Jeep, and tried with a hammer and open end wrench on the top flange for a good hour before it broke. Couldnt even get the press flares on the tube to go in. Any ideas on what the heck I need to do? So close yet so far away...
