My trusty Taco is becoming a royal pain in the xxx

09 base 2wd auto 207k : had a head gasket replaced a month ago. Down hill after that. One week later I get a p0420 code. Replaced the catalytic converter. Looking around I see I still have residual oil in my coolant container.. I flushed it got better but not 100% completely rid of oil it leaves a thin black film around the container. I just got thru replacing the battery today granted it was 5 yo. And the kicker....ever since I got it back from the head gasket job it shudders in a way I can't describe other than it feels like the in suply fuel line gets pinched & released..All this in the span of 4 weeks FUUUUUUUUDGE !!!!! HELP....

 

Can't complain too much you got 200,000 miles and over a decades use out of it. I wouldn't want to give it up.

 

Problems can be expected to rise at age and high mileage.

 

The battery and the cat issue I can definitely see at that age. But I thought the head gasket issues mainly dealt with 05-06? I haven't really seen as many on later models going bad but maybe I haven't been paying attention.

 

Save up and trade in for the 2022 Tundra!

 

Start with checking fuel pressure and a compression test.

 

OP has a 2.7 engine.
They didn’t have that problem like the 4.0.

While it’s not common, the 2.7 can have problems.
While the head was off, I would have had the updated coolant pipe put on. (Maybe he did?)

OP, I can’t help with the shudder.
Are you an Auto or Manual Trans?

 

Auto

 

You replaced the valve cover gasket and spark plug tube seals, as well?

 

No good freind. Im buying TWO new 2022 Tundras. Haaaaaaaa jk I can't back that up. I'm trying to first fix my 12yo bucket first then Ill spend 65k on a new truck. Lol

 

A valid point you have.... and if it weren't for my wifes 20 Camry XLE I'm paying I mite consider looking for a new truck. But for now I must maintain and drive this one.

 

I imagine the mechanic had to in order to access removing the head. Are you thinking a leaking injector ???

 

Pop the #4 coil out and see if it’s dry or wet with oil at the plug. I did replace a coil after installing new spark plug tube seals and vc gasket

 

So if the coil is wet, solution is replace the coil to fix the problem ??

 

It will need valve cover and spark plug tube gaskets first then any shorted out coil replaced

 

If it is wet ..is it wet with fuel ??

 

This is comical. One right after the other. Still no cel....

 

Motor oil

 

Not sure re the 09, but it might have been under the catalytic converter recall..my 2010 was. Run your VIN and see..

 

not to add salt to a wound

at 207k depending on Ur sightline to the future

U might have been better off thinkin upper head rehab/replacements ( both )
