3rd Gen Rear Main Seal leak

I am so bummed out. The rear main seal behind the engine blew out at 42,600 miles. Fortunately I bought the platinum warranty. A week to repair at least. I asked my rep at the dealership how common this is in Third Gens. He said not common at all. But I seem to remember reading several posts about this same problem. Thoughts? Crossposted in another AZ Tacoma forum so sorry for the duplicate.

 

The 3.5L 2GR-FKS will not be missed. Sorry to hear your engine's rear main seal blew out at such a low mileage.

 

My 16 Tacoma rear main seal just went out as well. I had an ex Toyota mechanic work on it in his shop and he said it looked like the seal had a bit of deformation. They no longer use the original seal part number and it's now a new number so I'm assuming the seal was upgraded. Anyway he changed it for $900 flat out the door. Took him 6 hours to do.

 

I've seen a few, not super common, but you are far from the first.

 

Couldn’t put numbers to it but I’ve seen a decent number of them here. If I had to guess maybe 20 or 30 of them. Most of them closer to 100k miles.

 

Toyota has been using versions of this particular seal (92 x 110mm) since the VZ engines in the late 80’s. There’s no reason for these failures to exist 35 years on…

 

Cylinder pressures have increased a lot since the 80's, leaks happen.

Would a catch can help? maybe? The 4 cylinder turbo is going have even more pressure.

 

Is there anyway to prevent the timing cover and rear main seal leaking?

 

Cylinder pressure alone is not a factor unless your PCV system or valve is malfunctioning.

 

Anyone in the Phoenix Az area know a good shop to replace the rear main seal? Mine just started so, yep, I am going to have to find a good shop or take it to Toyota and bend over.

 

do you know the new part number by any chance? Thank you

 

I have a rear main seal leak on my 2017. Noticed it at around 45k miles.

 

I've seen a few mentions of this, and I plan to replace the PCV valve every 20K miles or so. It's a $10 part and looks relatively easy to get to.

 

Way overkill, just check it, its a little ball inside and as long as it moves freely, its as good as new. Shoot some cleaner in, but no need to replace.

 

Thanks. I'll do that.

 

This isn't very TOYOTA of a thing to happen. The world is going to hell in a hand basket.

 

LOL i want to be an easter egg painted as The Rock in that hand basket you speak of

 

Hard boiled!
