Is an engine reseal worth it?

I've had my 2010 Tundra a little over a year. Got it with 118k miles on it and really have had quite a few problems with it considering the reputation these trucks have.

Rear main seal leak -- fixed this with some

AT205 reseal, luckily.

4wd stuck on -- fixed this by tapping transfer case with hammer luckily.

Secondary air injection valve -- replaced the valves myself for $140 luckily.

Windshield washer fluid won't spray with any pressure -- I've literally replaced every component of this system to no avail unfortunately. Probably spent $200-300 on pumps, valves and jets from Toyota.

Driver window sticks when using auto-down -- Haven't been able to fix this, either.

Window trim fell apart at all four windows -- Fixed this for about $150.

But now I'm getting into some serious repairs:

I noticed oil dripping from some lines at the front of my engine last time I did an oil change. I also noticed oil pooling up in between the intake and the heads.

I took it to the dealer and they said I have multiple leaks. Valve covers, cam towers and oil pan, mostly. Too fix all of these, it will be $3,900.

I got a decent deal on this truck when I got it ($17k) but it's kind of nickel and diming me to death. Is this engine reseal worth it or should I just let it go? I'd like to spend at least a couple months not dropping money on this thing. The whole idea when I got it was to have a nice reliable truck and low payments. But I seem to be making payments and repairs, too, all the time.

 

Replace the PCV valve and see how it goes. But I would sell it and find a better kept truck. Nothing you can really do to revive a neglected vehicle. At least, not cheaply.

 

I bought my 2011 Tundra with 205k miles on it 4 years ago for $9k and the one "issue" I had was the brake feel which was solved with new pads and replacing the old rubber brake lines with braided stainless. It still runs and drives better than my 2017 Camry did at 20k miles (better enough in fact that I sold the Camry and daily the Tundra!).

I would cut your losses and trade it for a different one. Thankfully the value shoulnt have down too bad in a year.

AT205 is my go to seal reconditioner just won’t work with high pressure situation like brakes. As far as your oil leaks I would do the valve cover and oil pan not too hard or expensive to do, the cam towers I would leave alone the top half of the engine has to be removed the cam tower chain /gear is under low pressure I would just add a bottle of AT205 and hopefully it will at least slow down the leak

 

I've tried the

AT205 for my rear main but it hasn't helped. How much have y'all added.
I even went with a heavier oil, 10W30, and still leaks.

 

One bottle with every oil change. Did it slow the leak down?

 

Nope, not 1 bit. I've used about 1.5 bottles

 

When was the last time you replaced the PCV valve?

 

Bought the truck in December.
I haven't replaced it, but that is a thought.

 

I would be reluctant to put anything in the motor oil unless I was completely certain that it would have no adverse effect on the anything in the lubrication system or performance of the synthetic oil. But that is just me...

I have used

AT205 in several engines, both automotive and industrial with success.
Also, I don't use synthetic oil.

 

Well I got a PCV Valve and changed it. And yep, the old one was not working. AKA: stuck/no rattle. We'll see how/if this works.

 

I like to change the PCV valve out every 50k miles they are cheap and helps with keeping internal pressure where it should be. I don’t rely on the rattle test I just change them

 

Not too long after I replaced the PCV valve, I did an oil change and added a bottle of

AT205.
I noticed that after about 2-3 days, the leak has completely stopped!!!!!!!!

 

I was under the impression that high mileage motor oils contained seal conditioners to slightly swell seals. Don't know how well it all works out.
