Maybe a collapsed lifter

[Chattzx]

So is there any sure way to tell if you have a collapsed lifter? Its not the VTC gears since I have them disconnected momentarily and 1-2 of my injectors are starting to go out ( I have new ones waiting to go in) but I am still hearing a decently loud ticking noise and I cant figure it out. If anyone would shine some light on my situation it would be awesome.

Listen to the 4 valve covers, and see if the noise is loud in one or more of them - that probably means you have a bad lifter and it's time for a flush.

You can use a long screwdriver, or even a pry bar to listen to the valve covers...just stick the tip on one of the covers, and put the other end to your ear.

they sell this xtream flush on z1 ive heard that it frees up everything and takes away all that noisy tick and what not might try that stuff....

Yeah I did that stuff about a year ago now and it worked but it seems like it has returned with vengeance haha. It seriously sounds like sh*t lol. I will have to try listening and seeing where the noise is coming from later today.
