![]() They've already lost me and I won't be coming back. Lexus needs to provide some form of compensation or else risk losing faithful customers. If you want the timing chain cover RTV gasket applied correctly it will be far easier outside of the vehicle. It was weeping pretty bad prior to replacing. The timing chain cover needs to have its RTV gasket applied correctly otherwise it can leak and depending on how wrong it is applied can cause catastrophic engine damage if oil pressure holes are covered. I literally just replaced my front main seal yesterday. If it's at the top, could be vanos (though you said it isn't), vanos line, timing chain tensioner or the cover itself. Owners will pay thousands of dollars just to replace a gaskets that is less than a $100. How high up is the leak If it's only at the bottom, it's likely the front main seal. I am extremely disappointed in the poor planning and quality Lexus has put into this design flaw. Once this is done, the repair will be reviewed by Jasper and make a determination if they will honor the warranty and maybe pay a portion of the repair bill. Its says 2285 to repair (Customer Pay), but 300 miles later he sold it to the dealer the next month and they want 9992 for it. The buyer must open a claim prior to having the work performed and pay the full price of the repair. Anyways, I did my research and found out that recently (08-10-15) the 05 had the Fluid leak and the details says they found the leak from the timing Cover Seal. And then even more bad news followed by Jasper's Limited Warranty. A year later it developed a timing chain oil leak and I was given the bad news about having to drop the entire motor just to replace the gasket. My insurance company, after much negotiations, agreed to have it replaced with a remanufactured Jasper motor that came out of a Toyota Sienna minivan, same motor. RX350, Sienna, and Highlander reseals run slightly more due to added AWD fluids, seals, and a small increase in labor.I have a 2013 Lexus RX350 and had the misfortune of running over a huge metal object in the road which destroyed the oil pan and then locked the motor. The repair is covered with the 100k warranty, and the head has to come off to pull the timing. 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. Turns out the timing chain cover and front crank seal are leaking. (just my luck) The book states that this is a 20 hour job in which the engine is supposed to be out to do the job. My mechanic said hes seen this only once before. It is NOT the HPOP or the normal leak points. I looked into the TSB for the timing chain cover, subaru says the only way to fix this is to pull the engine and re-seal it outside of the car. The top of the timing cover on my 97 F350 is leaking oil. The rebuild uses three entire tubes of FIPG to reseal everything during reassembly. My dads Forester's timing chain cover is leaking also, it only has 40,000 miles on the clock on a 2011. 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. Your timing cover gasket might be hiding a secret and that secret is that it’s leaking. It is very important to usean engine oil dye to help accurately locate the oil leak. These could be misdiagnosed as an oil pan seal or front balancer seal leak. 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. Possible front cover leak locations are the 90 degree and 45 degree plugs located on the front cover next to the A/Ccompressor. 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). ![]()
