I just noticed there is a moderate lifter tick on nearly every startup now. It was not like this before. Temp has been 100-110F outside. I am using an oil filter with a back flow value. Will this noise cause any damage? Is this common on higher millage engines? I know the Mitsubishi engines tick all the time and there fine but never heard of the Chrysler tick. I have heard of the Hemi tick and 3.6 tick which is bad news. I might be a bit paranoid because I did have a lifter collapse years ago.
