newby with 300D 300TD 240D 450SEL
Im going to swap engines in my 300TD the engine I bought has been sitting in a barn for several years in the dry. It ran when taken out. Should I lube anything before trying to crank it once I get it in. The 240 D runs but needs some body damage fixed I have all the parts needed except radiator to repair it. Any experience in these matters would be appreciated. Im a newby to the forum info. so I may do things awkward for a while. thanks ahead of time for any help.I have read I need to change filter clean tank and adjust valves and cable linkages to accelerator. Any other suggestions would be appreciated. 300td engine swap its an automatic. And a 240d front end repair.
