NEED TO KNOW THE YEAR. Some years had the 2-piece seal and some had the 1-piece seal.
All engines after 1986 give are take a month have the 1-piece seal and you must remove the engine are the transmission to replace the seal. OIL
Pan does not need to come off.
If it is older then a 86 then you will have to remove the oil pan and the oil pump and rear main cap on the crankshaft to replace the seal. Either way BIG JOB.
