And I have a different point of view...
I have the access to the clean and jdm engines and if they're not good I pull them off without hesitation...
And we work out all the possible strategies and then go in for the work...
I also give rebuild warranties. But sometimes in some cases swaps are giving many positive outcomes than rebuild and sometimes swaps have lesser positive outcomes, this is where I choose rebuild.
Like we are rebuilding the fj40 2F engine, whereas swaps are really expensive.. Uz's and vz's are way beyond 300k mark and diesel 2lte and some other are also beyond 200k..
