Hey guys/gals.... Ive had my truck for 3 years now, 2002 rcsb 4.7 with 160000KMS on her... I do all the service to her, I use mobil with a K&N filter... usually change it around 7000 or 8000KMS... I just noticed today some sweating at the front crank seal[:@] Now ive only lost about a litre between oil changes. Ive heard some ppl say that full synthetic gets into places that conventional doesnt, my question is do you guys think it will help the sweating/leak if i go back to conventional??

 

no.....when i was at the dealership we saw quite a few problems with 4.7 main seals seeping, most of em were on the grand cherokee but we had a fair share on the ram as well

 

Thanks for the info.... im guessing you guys were just replacing the seal?? what would that run.... couple bucks for the seal and a few hours labour??

 

yeah just threw in a new seal...not sure if the seal is availabe by it's self but here's the part number for the lower gasket kit: 5135796AA

that'll give ya both main seal, oil pan gasket, water pump, oil pickup tube seal and a few others....can't remember off the top of my head what the labor times are for doin it though
