2020 SRV6 4x4 White
1st owner
65000 miles
Failed head gasket and cracked block

What happened:
Mid June 2022 Driving down highway at 65 mph lol normal, heard a lil pop sound, then check engine light came on and ran like crap all the sudden. Temp gage was in the middle as normal. Pulled over within a few hundred feet and saw coolant over flowing and vapor coming from tail pipe while motor off..

Maintenance:
Oil change and service inspection every 5k miles

Usage:
-Light off roading (dirt roads, a few beach trips)
-Some towing but within tow rating and only about 100 miles per year towing

Mods:
Almost all stock
K&N air filter
265/75R16 BFG KO2
FJ Wheels
Cell phone booster

Coverage/Status:
-Outside of factory powertrain warrant so not covered there. Had MPP extended warranty and they covered it, but they’re putting in salvage mystery motor (55k miles on motor from truck that was totaled in rear end collision).
-Still in shop getting new motor and fuel pump recall repairs.

 

-Mileage that problem/failure happened:
48,700 miles

-What actually happened:
Oil drained into the head on a steep grade.....got sucked into the pcv/intake.

-Vehicle usage (towing/off-roading/pavement pounder):
Off-roading

-Vehicle modifications (tune/geared/tires):
5.29 gears, front and rear air lockers, 285 tires, Catch can. No Engine mods.

Dealer repaired under warranty. Removed catch can prior to taking in for service. Traded truck into same dealer immediately afterwards.

Thread below:
First indication was a check engine light and code (in thread). Dealership stated could be bad gas or the exhaust valves. After running good gas and check engine light returning a compression leak test performed to pinpoint exhaust valve.

Burnt exhaust valve. Engine removed and one head and exhaust valve and associated components changed. 30 days at dealership and covered by warranty.

When enquiring if they were seeing others Tacoma’s or trends. They stated they were but more Highlanders (same engines).

2019 Tacoma TRD PRO
56k Km

Customer states CEL is on. Code return, misfire cylinder 5. Long story short, cylinder 5 fails leakdown.
Passenger side head/valves replaced under warranty (this failure happened in late 2020).

Useage was pavement pounder.
Had a medium bed rack with RTT. Seemed to be stock otherwise.
