After 40k mile engine misfire

Hello tacoma world my 2017 trd sport has misfier in cylinder 1 & 3
I checked spark plugs, ignition coils, injectors all fine.
Idone valve cleaning.
Still same
I swap injectors and coils still the same.

Note these car exported to Oman and hear no
Dealer.

 

When you say checked, how did you check?

 

Running hot?? Any coolant loss??

 

Compression test ?

 

Do a compression check

EDIT: Bleep beat me to it

 

how are you determining misfire? If it’s via an app counter, it may not necessarily be a misfire. There’s an in depth discussion over in the tuning thread.

 

Has the weather been rainy? I realize Oman does not get allot of rain.

 

Thanks to you all,

Checked by swaping

No over heat

No coolant loss

 

Update!!!
Engine block crack

Estimate repair cost 3500 usd.

Case closed

 

your engine block cracked?

crazy any reason or anything you can find?

 

AT 40K?! Wheww! Good luck my friend.

 

$3500...it’s gonna cost a lot more than that in labor alone

 

Yeah should be covered 5 years/60 for powertrain

 

The reason which i can think about, after oil change to much oil enhailed by the intake bcause the dip stick which was unsecured.

It was too much..... and cylinder 1 and 3 where the best place to go in.



This Vehicle not covered by any warranty bcause its out side USA.

Lucky we Have Dubai lot of cheap spares

 

When was the last oil change

 

must have been a heck of alot

 

Time for a diesel swap

 

That’s odd, my cousin drove his TOYOTA Sequoia with the oil cap and the dip stick on top of the radiator for miles until I told him it was missing. It’s still running like a bat out of hell

Now there's a new on on me
