They don't make anything Liquid in a can that will FIX a rear main seal leak. Time to replace the seal and be done with it.
Save your money, only a new seal will repair a worn out seal. Be sure the crankcase ventilation system is working properly.
The rear main oil seal would be the bigger repair job on most engines.
You will have to replace the rear main seal. This will require that the transmission be removed.
NO it will not. That is BAD stuff to put in the engine oil. You need to check the PCV Valve and make sure it is working. If it is then you will need to replace the rear main seal.
I just gotten a quote for a 2001 ranger 2wd 3.0 automatic. The quote was $550 to replace the rear main seal. This is from a privately owned repair shop.
Once you get to the seal it is an easy repair. Problem is you must remove the drive shaft, 4x4 differential, and transmission to get to the seal. Not an easy repair.
No, it won't. Bar's Leaks Rear Main Seal Repair uses compounds which interact with the rubbers and plastics used in the majority of engine oil seals and some gaskets. These are mostly seals around rotating components or shafts, such as o-rings and circular seals. The product coats and swells the rubber in these seals, to get them to seal again after they have been worn down and deformed. The majority of flat surface gaskets are fiber, and all head gaskets are metal or composition (and even these seal around the cylinders where your leak usually is with metal). Rear Main Seal Repair will have no effect on this material. If the head gasket is leaking coolant, then Bar's Leaks for radiators may solve the problem if it is a minor leak, and is not affected by cylinder compression.
It cost me $817.50 in a 97 Holden rodeo 4x4
That is a huge job. You have to remove the transmission before you can remove the flywheel. The main seal is under the flywheel/flexplate. Rick Visit my auto blog at http://free-auto-repair-advice.blogspot.com
It depends on the seriousness of the leak. Basically, if you car is not in top condition/repair you should not drive it.
Labor at a dealership will run about $1000, plus parts but the seal isn't that expensive.
DIY: $20.00 (for the rear main seal) plus your time Mechanic: Depends on the mechanic/shop but will likely run you around $300.00
