However I had already purchased a Cummins OEM seal before the project started so it was going in lol. Well after further understanding the Cummins adapter plate and the seal, I don't really think I did. Now when I first started on my truck I "thought" I had a rear seal leak. I had my transmission and flex plate out of the vehicle already, so it was a no brainer to replace this seal. I will start with the rear main seal because it was more straight forward. Keep em clean.įYI: My post is not a 100% how to, but a little reference and maybe some help to someone with similar issues. I hate dirty engines and grease covered parts. Neither were bad enough to drip on the ground when parked overnight, but there was enough to make things turn oily on the surrounding areas. Before I started the work I knew I had an oil leak out of my front main seal on the crankshaft seal and I thought same for the rear. I think sometimes it can be gross leakage, but we've have a few cases that were absurdly minor.Recently I did some extensive engine work to my 20 with the 5.9L Cummins engine. And when ask to see proof or pictures, often they (service writers etcetera) kinda fade away. Not sure, but it seems as often as not the leak is between the seal cover edges and the engine block/head. Dealerships were on a few occasions coming in around $1700. It's not clear from OP what they want for just the reseal, but it seems pretty steep. Dealership come up with leaking timing chain cover pretty regularly. PS - I attached the four photos they put into the inspection report. I apologize for bringing this up in a Prius forum, but I will say that a used Prius might be one of the cars I would replace it with when the time comes. I worry that my big “Toyota 5-Star” dealer generally overcharges (though I think they perform good service), and such an expensive repair will have to go on a credit card to be paid off at bad interest rates The car has 140,000 miles on it, and I really can’t afford to replace it, especially with current used car prices. But in reading about it online, and particularly this thread, I am definitely wondering if this is over charging for something that could actually be fixed (or at least tried) in a different and much cheaper way. The inspection report said “Timing cover gasket: Noted the front portion of the timing cover is starting to leak oil.” And they listed it as a “needs immediate attention“ repair. Hi Mendel - Do you know if similar issues apply to Toyota Avalon hybrids? I am facing this recommendation (leaking timing cover replacement) on my 2014 Avalon hybrid for over $2800 US. It's a high profit margin item for the dealer, when it is most likely the front crankshaft seal - a much less expensive replacement. Reinstall remaining items in reverse order, torque per Repair Manual.Ī leak in the front crankshaft seal will migrate to the harmonic balancer and be spun and spayed all over the front cover. Install timing chain cover and install/torque all bolts, per Repair Manual. Apply bead of of Toyota seal packing, spec and location per Repair Manual.ġ0. Clean all mating surfaces between timing chain cover and engine block/head.ĩ. Pry timing chain cover partially loose, then unbolt and remove water pump. Just off the top of my head:Ģ.Remove oil filter and oil filter bracket. Dealerships were on a few occasions coming in around $1700.Ībout half that amount seems fair, my guesstimate.
