Asked by Elveen
When I press the accelerator, my 1998 Toyota Prado revs quickly and the engine sound goes up. However, the pick-up of the vehicle I believe has reduced. It sounds like a Toyota Landcruiser accelerating. The turbo, I also feel, is not working effectively?
The Prado has also recently gone through an accident where the front grille, radiator and chassis was damaged. This problem has arisen after this accident. The car has covered 390,000km. What could be causing this?
Answered by CarsGuide
22 Jan 2024The clue here is that the problem started after the repairs were made post-crash. It sounds awfully like some of the turbocharger's plumbing has been damaged/gone missing after the crash. If so – and it only takes a minute crack in the piping – the engine can lose turbo-boost, which will produce the precise symptoms you've noted.
While the turbocharger itself will be working fine, the boost it produces is being allowed to escape into the atmosphere instead of being pumped into the engine to produce more power. That's why it sounds noisy, and also why it's not delivering the performance you're expecting.
