I have 3 ea82 motor one good runner no problems its a 89 gl motor also a good runner with a small mysterious external coolant leak its out of my dd 91 loyale and my 93 loyale parts car has milky oil I'm hoping to run all three motors my question is is there any difference in the Model year motor ie any power or efficacy differences and what parts if any I think I'm looking at 2 sets of head gaskets anyway the 89 and 91 have the same amout of miles around 150ish and 93 has 225ish on its clock so if there's any better parts on the 93 it might be worth swaping to another motor or doing a full rebuild on the 93

could be carburator, spfi,turbo, etc...

 

pictures would help....

There all spfi motors the 89 motor and Dr trans droped right in the 91 with very little parts swaping just wondering if there is any internal differences between the years the 89 seems like it has alittle less power but that could be a lot of things

I can't think of any significant differences.
