Does anyone know the laws on motor swaps in washington state. I am looking at putting a 4bt into a cherokee but need to check on the legality of it. I live in a section of washington that has to do emision tests.

in oregon i have been talking to deq and dmv and been getting conflicting stories. my crew cab is rated five hundred pounds under the exemption weight. i ask if i could use my 91 cummins title and sounds like i have to use the 78 title i ask if i could raise the gvw of my 78 by adding springs . have not gotton a answer and when i do i will get it on paper. if all else fails i am going to farm plate it. my understanding of the emmisions rules are that the engine has to pass the deq for the year of the engine including any evap system. but that is not in stone.

In Washington it looks like they go by year of vehicle in the areas that require inspections. 1983 and newer. They have a web site that explains the testing requirements for the different years. Couldn't find any informations on engine swaps yet. Has to be somewhere.

I emailed the the washington state department of ecology. A specialist returned my email and said he wants to talk to me directly about doing this. I will keep you guys updated. Thanks to everyone for the help.

No big deal in Oregon. After all, You could buy a 1/2T chevy in 78 with a 350 diesel. It had no egr or smog stuff. They used the 6.2's in half tons up to 93 and 6.5 in 1/2T till 99. The 6.5TD and 454 burbs have a gvw of 7900lbs, yet they have the over 8500lbs hd engines with no egr.
