Seen a YouTube video on replacing the timing chain and gears on a Gen 5 and it’s a 10 hour job per the book without removing the engine. But lifting it once, hanging it, letting it down reduces some of the headache. I’m sure you could find a bar that is stronger than wood to hold it. I’ve had to do it on an F150 and used a pressure treated 4x4 across the fenders with thick towels underneath to hold the engine so it was only lifted and lowered once. I suppose it comes down to what your time is worth and if you have the equipment to get the job done? But I honestly don't know how you would accomplish that on jack stands, the amount of wiggling, cursing, and trying to maneuver the upper oil pan to get it physically out of the way seemed hard even with the vehicle on a proper hoist. It is by no means easy and extremely frustrating from what I saw but it did allow my coworker to leave the engine in the vehicle and get the job done. That being said, it is possible to drop the front differential, jack the engine up and slot 1~2" (I forget exactly which size we used) thick blocks between the motor mount and engine brackets to lift the engine up enough to wiggle the lower oil pan off and out. It's how you're supposed to do it per the book because of the placement of design changes when they went to dual VVTi and relocated the oil filter housing. I mean if you're not squeamish about pulling the engine out of the vehicle and you have an engine stand it's doable at home. From what I know, because the 5th gens oil filter bracket is attached to the oil pan, instead of up top like in the 4th gens, you must drop the upper oil pan to get the timing cover off. Have the leak and want to fix it myself to save 2 grand but just want to know how others have gone about the fix if they have done it. Wondering if anyone has DIY'd the timing chain cover reseal on a 5th gen 4runner yet. So, how many people have had this issue on a 5th generation and does anyone know what goes into the replacement ? I was thinking on 4th generations the engine had to be pulled for replacement.īased on my forum experience I would not say "this is common", based on the above thread I would say "but occurrences are documented" I was told they would need the 4runner for 1.5 days to replace. Luckily, after examining it they found it was in fact the timing cover. I took it to another dealer and mentioned that I suspected the timing cover was the issue. So, I narrowed it down to the timing cover. I watched it for a while and decided to degrease everything and I could then tell it was coming from up high and draining down. The first dealer changed the oil canister housing which resulted in no change. I've been dealing with the issue since the 10k mark. So, I was checking the 4runner out which is a 2015 Trail with 31,200 miles.
