The purpose of this thread is to determine non-Toyota engine swap options for the LC200 platform.
Hi I am new to this forum. I live in the USA and own a 2008 LC200 with the 3UR-FE.
Approximately 1 month ago while on a trip to the beach with my family the cruiser broke down. While driving on the freeway, the 4low light came on, along with the flashing check engine light followed by engine vibration. After exiting the freeway and parking, the engine would barely idle and it was clear that at least one cylinder was misfiring. After having the LC towed to my trustworthy mechanic, it was determined that the head gasket blew between two cylinders on the passenger side and I had three bent/hanging valves in one of the effected cylinders.
After much consultation between my mechanic and reputable Toyota experts, it was determined that the recommended practice is to never rebuild UR heads. In fact, he tried to consult several machine shops that he uses and they all refused.
I opted to go for a used engine swap and the new (used) 3UR-FE is currently being installed. I’ve been doing some research on my own and have found Toyota master mechanics who talk about this issue with the 3UR-FE. The 2007/2008 3UR-FEs break valve springs. The issue happens rarely 2009+.
This event has led me to question the reliability of the 3UR-FE. Mine had ~125k miles on it, never even got close to being hot. The used oil was always in great shape after changes. Oil pressure was always consistent at ~1/4.
If this happens again I will be looking to swap for a 6.2 LS. Has anyone done a similar swap?
