rebuilt on ebay says is for a W commanche

[ammohead]

My Vin JTWL6517GT212858. Seller says I must have a W in the eighth spot. Other threads in this forum state that the 8th spot is for load capacity. I don't want to buy the wrong engine. I know that originally my commanche was a CA emissions model but most of that went bye bye a long time ago. I live rural and don't have smog checks. Can you help me understand better how to determine if this engine will work?

8th digit is usually, but not on all vehicles, the engine code. But you missed the first digit in your's. There is a 1 for "made in USA" in front of the J, making your 8th digit a 1.

Turns out in ours the 4th is the engine code.

B is diesel

H is 2.5 Fuel injected

U is 2.5 carbureted (84-85 Cherokee)

W is 2.8 v6 (what you have)

M is 4.0

Fourth letter on my '90 is a G, and it's the GVWR, not the engine. 8th letter is engine. E  for 2.5, L for 4.0, T for 4.2, and 7 for 5.9. So apparently the different years have different code sequences (which figures if his 10th letter G would indicate 1986 model year. My 10th is an L indicating 1990 and they would skip the I in the letter sequence. And if my logic is correct, then your 10th character, mvusse, would be H for '87).
