Front seal couldve been boogered up by the. If the screen is bouncing around in the camshafts and rockers, it will score the lobes and start to seize a camshaft which in return will make you skip timing. Could it possibly be the front main seal I would think with a gasket and sealant the timing cover shouldnt leak. There may be updated revisions on these gaskets but this is what I had down in my spreadsheet! I would buy the gaskets myself before going to a shop and tell them to give you the old gaskets back in a bag so you can verify they did what they were supposed to. Here is the part numbers for the gaskets you'll need to have replace when you have it checked. I was told by two (got a second opinion) that I have a timing cover leak that will need to be fixed soon. Preventive maintenance or spending a few hundred for a shop to take a look and verify and replace gaskets is better than 2 to 6k for a rebuild or engine swap. General F150 Discussion - Timing Cover Oil Leak - Hello, I own a 2015 Ford F-150 XLT with the 3.5L Eco Boost with 67,000 miles on it. If the top end is getting starved of oil, it will be a bad situation. Could be a bad PCV, a plugged oil galley(screen clogging), or simply bad gaskets. The screen is very common, the ball is not. make sure the screen and little ball bearing has not dislodged from the bridge. Very minor kinda like just a stain showing. Had it checked out before I got it and found it had a Front Engine/Timing Chain Cover Oil Leak. Have them pull off the upper timing chain cover and pull off the Camshaft bridge. 1 I just bought a 08 Lexus ES350 with 151k miles. Im looking at a 1000 - 2200 fix depending on where I bring it. Do you actually require the special tools for timing the engine. I found a manual in doing this but I was wondering if anyone had done this. The timing chain cover is leaking by the alternator. I was told by two (got a second opinion) that I have a timing cover leak that will need to be fixed soon. I finally found the exact spot I had the oil leak on the front back side of engine. If you are not mechanically inclined I would suggest taking this to a shop. General F150 Discussion - Timing Cover Oil Leak - Hello, I own a 2015 Ford F-150 XLT with the 3.5L Eco Boost with 67,000 miles on it. The only spot i could find some small fresh clean oil trace was under the Magnetic Variator so i assume that the magnetic variator seal is leaking (a little bit)Ĭan i only replace that seal by removing those 3 screws from that cover or do i have to take off the whole upper timing cover ?ĪrthurDon't even start the car at this point. I didn't find "fresh" oil traces as far as i could look/feel upwards. RX350, Sienna, and Highlander reseals run slightly more due to added AWD fluids, seals, and a small increase in labor.Today i went under the car (removed the engine undertray cover) to find out more about where the oil leak might come from. 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. The rebuild uses three entire tubes of FIPG to reseal everything during reassembly. 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).
