1hz rattle when cold
hey all, my 1HZ 100 has a rattle from motor when cold, but it only takes about 2-3minutes of driving and the noise dissapears and never hear it again till the next cold start up, changed my oil and added a bottle of nulon deisel oil treatment and made no difference, does any one have any ideas or have the same problem?
Re: 1hz rattle when cold
Sure its not just "diesel knock"? Pretty common for diesels when they are cold.
Re: 1hz rattle when cold
its just what they do mate. ive had my 1hz fully rebuilt done just clicked over 10 000kms. made a rattly noise on start up after 335 000 and makes the exactly the same noise now lol. dont stress. id say its because of the oil being so thick when its cold. i dunno

Re: 1hz rattle when cold
It could be a timing problem related to the cold start device (acsd) on the injector pump. Easiest way is to remove it and install a plate over the hole. It doesn't get cold enough here to need one.
The worst part about being told you have Alzheimer's, is that it doesn't just happen once.
