Toyota dealership changed oil for me and found 2 problems to fix

Toyota dealership changed oil for my 2006 Tundra SR5 and found 2 problems to fix, and asked $2,000 and 10 hours of labor.
1. PCV valve. I bought the part. Will replace it myself.
2. Rear Main Seal oil leak. I want to DIY to save.
Any advice for #2 to DIY?
I am sourcing 2 ramps so Tundra 2 front wheels can ride up on them and give me more room to drop the transmission after taking out the transmission and engine oil.

 

Good on ya T18. My PCV valve was clogged for quite a few years and it was never realized until learning about its importance on this site. Such a little thing can make a huge impact on engine health. Your clean up job looks good. Looks like you bought a new one which is even better.

 

Is that your picture or someone else's? I don't see any way your PCV caused your rear main seal to leak.

Have you actually crawled under there to check for leaks? I wouldn't take their word for it. Replacing the rear main won't be fun if you decide to do it yourself. Personally, I wouldn't fix it unless it's leaking really badly.


Also, the rear main seal was leaking on our Rav4 but stopped. I switched to Mobile1 high mileage synthetic which has a conditioner for the gaskets. It seems to have helped.

 

Thanks. Yes, waiting for new part to come. Cleaned it for now.

Read about mid-way down in the article. Its possible especially in multiple locations per the article.

 

And @FirstGenVol suggestion of switching to Mobil1 High Mileage may help your problem. If its not leaking too bad, then switch to the new oil. Give the additives time to work. Monitor the leak every couple hundred miles and you may see an improvement. In the end, a new gasket seal replace is best.

 

dealership showed the leak to me when they lifted my truck. I also noticed oil drops on my driveway. I am pretty handy but never done this job before.
I had to fix a $2k job for a stuck broken speedometer for my old 2001 Nissan Pathfinder which I replaced with this Tundra in July this year. I think the owner knows this problem and decided to sell and get a new truck.
The speed sensor was stuck in the transmission and my local garage was afraid to do it fearing breaking my transmission. My Nissan dealership wanted $2k to replace the speed sensor. I diy drilled the sensor out of the transmission without damaging the transmission. But, it took me several weekends to get it done. The entire DIY job was posted on my YouTube channel to help others.

 

dealership charged $120 to change mobile 1 oil. No, the leaking is not too bad.

 

Sounds like you are on the right path if your new oil has the High Mileage Additives. Next time you can DIY the oil change for less than $30 with filter. Walmart has the best price on oil and you can get the OEM Toy DZZZY-3 filters online for around $4 each.

 

I always question if the dealer is being honest with me. Several years back I had a Honda Element. After a deeply discounted oil change they told me the rear diff fluid was shot and I needed a complete flush and fluid change. I don't remember what they wanted to charge but I can still the look on the poor girls face when I told her it was a front wheel drive only vehicle.

 

My element needs rear diff fluid changed, thanks for the reminder.

 

Or the time the stealer was doing my annual inspection and sales guy over phone said my tires were too big (285/75/r16) because they were barely rubbing on the frame (think paint rub). He was going to fail the inspection.

Me: Really? Thats funny because you put them on 2 years ago. Check your records.

Him: (silence) oookkk...

Me: Thats what I though. See you later with a fresh sticker. Hahahaha

 

Autozoned is having a blinker fluid special right now.

 

Ha, the vote is 50/50 to DIY to save this $2k job. Ya, i will go to Walmart to get mobile 1 oil and filter next time to change oil myself. Save almost $100 DIY oil change.

 

with only 4 voting. I personally would prefer to hear more posts from actual posters like PHM/FirstGen than put much weight on drive by voters who may or may not know what the hell they are voting on. As Firstgen said, it ain't fun but very doable with patience and a good level of experience.....especially when searching youtube for a good DIY video

 

No no, my Element is 4wd. Thing it like a mountain goat in the snow, I love that thing no matter how it looks.

 

If you check your oil regularly and weren't losing enough to notice that you were losing some, I wouldn't change it, I'd put in the mobile 1 high mileage and keep an eye on it. One other thought. I'm not sure about the 4.7 V8 but in the 3.4 V6 the valve covers can leak towards the back and over time it will run down the back of the engine and can look like a rear main seal leak from underneath. A valve cover job is probably $500 compared to a rear main seal job being $2000. If you don't really trust your dealership make sure you examine it thoroughly to confirm the source of the leak before attempting to replace anything.
