Shrewd

Hi All,
I just bought a Lexus and discovered it has a sound from the engine. It sounds exactly like this video. The poster never mentioned how he fixed it. Can you guys give me some pointers.

Hi, Im having the same problem too with my 2007 es350 UL. I complained it to my lexus dealer and they diagnose it as the camshaft is loose that's why the engine is loosing pressure. They replaced the camshaft. But after, they noise was still there. Pretty disappointed with the diagnose they made and nothing changed with the engine. The sound was still there. It happens during the first 15min until it reaches the running temp and quiet down a little bit. Is it possible that the engine needs some valve adjustments?

SILENTM

Sounds like the variable valve timing cam gears, any faults stored.

Hi, no check engine light. Lexus replaced the vvti cam gears already for me but still... the sound im complaining about is still there. they heard it and they said its normal cause the engine is an aluminum block expands and contracts on temperature. But to me seems like its more to that... it is really loud when you drive it during cold start.

that is the cam gear rattling. That is not normal. They need to fix it again from the recall
