Hi guys. My Fortuner has about 4000k on it now, Ever since I bought it it has what sounds like a heavy diesel knock when taking off from stopped. It is a manual and this pretty much only happens as I take up the load on the clutch as I take off. Sometimes it happens as I change into second at really low revs with engine under load. Took it to dealer and was told it was an engine sound and no problem. I have been driving diesels for years and never had this problem . Sometimes when the engine heats up it almost goes away, but never totally. When cold it is a loud, very loud knocking sound till the clutch is released. As engine warms up it starts to go away. Some times it does but most times it is still present at a quieter level. Sometimes a quiet knock is even present while driving. It's really a cross between a knock and a rattle. Probably a bit difficult for dealer to diagnose because by the time I get to the dealer the engine is hot and the knock is now quieter more normal. This is a knock knock sound not a tapping sound. Any one else having this happen as if others are having the same sound it is normal, although hilux users (same engine and clutch et) apparently don't. The car has a tow bar fitted but has as yet not towed anything at all, so is not a vehicle abuse or overloadng problem. It is an as delivered to me condition. Vehicle had 40 km on odometer and 23 km on the trip meter. I would doubt it was caused at the dealership there fore and would be an off the production line condition if one exists. Any help or advice or suggestions appreciated.
Cheers.
Cheers.
