marcus 0 Posted August 27, 2020 There is a ticking noise when idling and revving, the car has been recently revived after sitting for 18 months. I had changed the oil it has 15-40 in it. I have heard you need a thicker oil, I have also heard that the tappets could need replacing. What do you guys think would fix the issue? Share this post Link to post Share on other sites

What do you guys think would fix the issue? hi marcus, there are way too many variables. The most common thing that would cause this is a dead hydraulic lifter. The tappets, or rockers if you will, they generally don't need replacing, but what drives them does. That being lifters, and pushrods. are you able to post up a video of the issue? If it has been sitting that long, it may take some time to get things running as they should. My bet will be a sticky lifter, that may eventually come good again. 1 gerg reacted to this Share this post Link to post Share on other sites
