Guys, bought a 12H-T from Japan a couple of months ago to put into my 1986 HJ60. It is currently at my shipper's place and he sent me few pics before putting it into container. The engine is from 1987-88 HJ61 with auto transmission with 190K. It looks pretty dirty and leaks at some places. I will try to clean it up real good but wondering if any other preventative maintenance need to be done before putting it into engine bay. Any ideas, suggestions like changing seals, gaskets etc to avoid work after engine is in place and makes it hard to reach or require significant disassembly. BTW, do you see any missing parts needed to put it into HJ60. Thanks.
