2000 Toyota Tundra 4.7 Have A Interference Engine
The Toyota and Lexus 2UZ-FE 47L V8 is the gold standard of reliable mid-sized iron block V8s.
2000 toyota tundra 4.7 have a interference engine. But the way the pistons have large valve reliefs cast into them and the tundra has an 85 compression ratio. The 3MZ and vvti 1MZ being notable exceptions. Toyota and Lexus 47L V8 2UZ-FE timing belt replacement note.
The 47 is an interference engine which means that if the engine gets out of time the valves can hit the pistons. Our Toyota 2UZ-FE 47 liter Long Block Crate Engine is on sale. The 2UZ-FE engines are almost bulletproof the most reliable and durable engines from the Toyota corporation.
Timing belts are costly and at 194000 miles it should have had its second one at 180000. Are interference engines better. My dealer told me he sees timing belts break with no enginevalve damage.
In comparison to non-interference engines interference engines breathe better because the valves can open earlier close later and open wider. This 47-liter engine was manufactured from 1998 to 2009. All the vvti engines are interference engines which is why Toyota moved back to chains instead of belts.
So much confusion too with the 2001-04 Toyota Sequoias and 2000-2004 Tundra with the 47L I own a 04 Sequoia. I have a 2010 60th anniversary 47 litre V8 petrol Land Cruiser. The first generation of the engine could be found in the following vehicles.
I dont know if youd hear the sound of valves hitting pistons but it died very quietly. 15L 1A-C 3A-C 3E. Ive heard it is and that it isntlol pretty sure after 04 came gen2 47 VVT.
