Hi all, I got a quick ? if anyone can help itd be great. Ive got a 92 Loyale wagon 4x4 Ive been workin on for a while. The timing belt busted a while ago and I just now got the timing right but it only turns to a point and then locks up. My ? is are there any other year/model engines I can look for that wouldnt be a nightmare to swap out? really dont want to tear this one down again but cant afford much either. Any insite, or advise would be awesome. Thanks
