Whats the worst a collapsed lifter can do?
my engine has an annoying tick that come and goes, im 99% its a bad lifter, and right now i happen to be at a point that i could pull the heads and switch them pretty easily, i just dont have the money
So my question is, if i dont pull the heads and keep the clicking lifter, what is the worst thing that can happen? also my car is turboed so it make a very large amount of power,
thanks guys
also im 99% sure its a lifter because it dosent always make noise, my oil presure is always 50+ and performance hasnt been affected

Its a game of Russian Roulette.. A collapsed lifter can cause problems, such as intake backfiring, detotation, upper valvetrain damage, camshaft damage, or worse, the lifter can come apart and drop the needles into your oil pan and get passed through the oiling system. It could happen today, it could happen a year from today, but ask yourself, is it worth it to fix it now, or replace the motor later on?

There are no needle bearings in a lifter (rocker yes, lifter no!)
A collapsed lifter will result in more noise.
There is only about .020" that changes so the odds of the pushrod jumping out are pretty slim.
I wouldn't be racing around on it, but I don't think your risking much.

Your making a wise choice to change them now.. Yes, having only .020" may not seem like enough to cause damage, but its enough to beat the lifter and you cam to death when its happening a couple thousand times a minute...

I have seen more then once lifters tearing up complete motors.
I myself had my car on the dyno on a monday and all looked good.
Made great power etc.
Pulled the motor as I was going bigger and pulled the pan.
Found pieces of the lifter in the pan.
Flipped the block over and the block was cracked, cam was dicked all to hell and the motor was no good.
Ended up pulling the heads and they were fine.
Sold the heads and threw away the shortblock.
