Hi folks ... New to this forum and also to Toyota diesels and diesels in general, so have a question for all you long-timers. Adopted this 81 pickup from my auntie who had it on her desert homestead. She's never seen salt (The pickup, not the auntie). Took it back east. Want to change out the glow plugs because of hard cold weather starting and too much smoke on startup. 240k, with questionable rebuild by previous owner at 200k. Is it best to stay with OEM or is there a better aftermarket glow plug. Been reading up on the different heat ranges and patterns. Have no clue how to know what is best. Any thoughts?
