2.7L front seal seap

Well guys I crawled under my truck today to inspect a few wires that I have previously routed and found a nice surprise.
I looked straight up and saw oil spray on my transmission lines headed to my radiator. So I look around and see right in front of me my front main seal is leaking. I would have taken a picture but the rain had other plans for me.

I used to own a 98 Avalon before the truck and I have seen tacomas and toyota pick-ups with over 150,000mi. and no seepage from the engine seals.
My truck has just under 74,000mi. and the seals seem to be going out.

Any others have this issue on their trucks?

 

negative. this is the first time i've personally heard of this.

 

If this was common I would have no problem with it but as it looks my truck will be heading to a shop to get resealed as soon as I get the opportunity.

 

I have had both the fron and rear seal replaced on mine. Luckily it was under the extended warranty.

 

The dealers here will not cover it since the truck is at almost 74,000mi. But I have MPP warranty so it can be used at any shop, so it will be going to someone I can trust rather than the dealer.

Glad they fixed yours without a hitch. How many miles was on the truck when it was resealed?

 

A little over 60,000. Just past the powertrain limit. My extended Warranty has paid for itself a couple of times now with the work I have had done.

 

Warranty is a good thing thats for sure. Although seals should not be leaking at this low of mileage.

 

thats true unless there is something wrong like loose crankshaft bolt or bad pulley.
bad pulley will eat the seals pretty quickly. When you changing the seal clean pulley and check if it wobbles.
Also forgot, seal should be geting oil from the inside of the engine, is it possible you running with lower oil level ?

 

Done that while it is on the truck not a bad pulley on mine. Then turned around and measured endplay and nothing is out of spec so far.

I am just wondering if I may have too much blow-by in one or more of the cylinders causing it to pressurize the crankcase and have the seals leak.

 

Thats a possibility but I would think PCV valve would take care of extra pressure. Whole front under the timing chain cover is open area so any extra gas I would think would affect the PCV valve first.(maybe good thing to check pcv )

Also there is ofcourse simplest possibility ever.
a. You are very lucky and piece of dirt managed to lodge itself on the seal lip and tear it down .
b. You are very lucky and got the only truck for a year manufactured during Superbowl and whoever installed seal just installed crooked.

The good part is,a front seal is very easy to replace so once you remove that seal you will probably know.

 

HAHAHA....I bet that would be my luck. I will check the blow-by and PCV valve and see what going on.

I still believe the seal is dieing.
