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. They say it is from the chain drive casing. Took my 2007 ES350 in for an oil change (not my dealer but a local shop I have used before) and asked them to see where the leak is coming from. 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 I have had some dripping (very slow) engine oil under my car last few weeks. 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.

Clean all mating surfaces between timing chain cover and engine block/head.ĩ. It is safe and compatible to use in your Lexus ES350. Pry timing chain cover partially loose, then unbolt and remove water pump. Yes, the BlueDevil Oil Stop Leak would be able to treat a leaking timing cover gasket. 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. RX350, Sienna, and Highlander reseals run slightly more due to added AWD fluids, seals, and a small increase in labor.Click to expand.It's not that uncommon. CARspec cleans the entire block’s sealing surface and timing cover of all old FIPG and oil residue, taking special care to reapply extra FIPG where the leak may try to redevelop.ĬARspec offers timing cover resealing at competitive rates, including all new gaskets, FIPG, 1282b, coolant, and post-repair alignment. Some RX350 developed timing chain cover oil leak from a few thousand miles of. The rebuild uses three entire tubes of FIPG to reseal everything during reassembly. The 2016 Lexus RX 350 has 6 NHTSA complaints for the engine at 13,436 miles average. The procedure to reseal the timing cover is time consuming, requiring the entire drive train be dropped out of the car onto a table, cleared of all auxiliary system, totally torn down, cleaned, reglued and reinstalled back into the vehicle. The original FIPG fails, leaving the owner with a mess on their hands and an oil-covered serpentine belt. This flexible gasket is similar to the silicone liquid gasket you’d use to seal a bath tub or window but is designed to withstand the heat and vibration of a modern engine. The timing cover is sealed using Toyota’s fix in place gasket, FIPG, and 1282b sealant lining the edge of the cover where it meets the block and cylinder head. While the cause of the leak is up for debate, the source of the leak is always the same: where the timing chain’s cover meets the block meets the cylinder head (as seen above).
