Hi i have a 4 L petrol 2004 prado, and have had a ticking noise on while accelerating, does anyone else have this same problem i i took it to my local mechanic and he thinks its nothing to worry about but i hate any noise thats not normal, i was originally thinking the exhaust manifold may be leaking but the mechanic assures me its not, any other ideas?
cheers

Ticking noise while driving on acceleration

My mate and I both have 4L Prados and they both make the same noise. Even at idle there's some ticking too. I've read in some threads here that changing the headers help with removing the noise.

Re: Ticking noise while driving on acceleration

It is to do with the manifold, sounds like the gasket has a hole in it but it doesn't. Standard fitment for the 4lt. If wind up the window u can't hear it.

Re: Ticking noise while driving on acceleration

hi mate,the other replys are correct.it is because of the thin material used on the headers.I was toyota foreman for 5 years and had hundreds of complaints.I also have grj120.it is normal.
