3.5L V6 or 4.0 V6 more reliable?

But how does fuel get to the timing cover sealant to degrade it?

You gotta be able to back up a wild claim other than saying we are done.

 

Perfect response from someone who doesn't know what they are talking about.

 

Ok I'll bite. Your whole spew here is completely wrong. Folks are calling you out due to these nonfactual statements. Air filter, oci, pcv, maintenance have ZERO to do with the timing cover leak. I think and I hope you were joking. Have a nice day!

 

its only important for me to know

 

It doesn't matter what others do, believe or do. The only thing that matters is that I know what works or doesn't work. Other's have not walked my walk, or learned what I have learned first hand

 

Thank you!

In all these timing cover threads he keeps saying how its preventable with no real evidence to back it up other than his Tacoma not leaking after his own maintenance protocol. It proves absolutely nothing.

 

But you don't know what works to stop a 3.5 timing cover leak. You are guessing at this point. Any decent mechanic should know better to NOT do this.

What is causing the timing cover leak? Nothing? Probably not. Something? Definitely. What is it? Nobody knows. Kinda weird, almost creepy.

 

If preventative maintenance isn't working for you, you got to ask yourself, Why?

And do you know the answer to that? No, you don’t so I’ll give you a hint, maybe you’re doing it wrong dude.

How do I know? Because it works for me

 

The cover leaks are likely less than perfect sealing surfaces compounded with the oil pressure inside the timing cover. Sooner or later some will find a spot to leak.

 

Stop with the weird GIFs

I don't know the answer and that's my point, neither do you lol.

You might have been a mechanic for 40 years... changing oil at jiffy lube.

Alright, dude enuff of your ignorance, off to the ignore list you go

 

Has anyone that has ever had a leak or seep, ever think of checking to see if the fasteners were still tight before they replaced it?

That’s all I ever did to my rear diff seven yrs ago on my '16 Taco, when they issued a recall for leaks. I tightened to the correct torque in the correct sequence, cleaned it up and it never has seep or leaked since. That’s PM, and it works

 

lol. 100% a lube tech.

 

Lol.

 

knew it, F'n trolls, but we do make it easy and attractive for them, so who's to blame?
The guy didn't even strike the match, he just doused the full dumpster with gas, and walked off giggling.
