"lifter" tick causes what damage?

I think I've got a ticking "lifter" that is rearing its head now that it's cold out.

Running the motor hard with this condition, what damage would it/could it cause to the engine?

you could potentially collapse a lifter and if that happens, the follower could fall out causing PTV contact.

A hydraulic lifter that ticks during a cold start and then stops after the engine is warmed up is loosing its pressure when the car is turned off. Because of this that rocker arm has too much slap causing the tick. I drove a truck five years with a ticking lifter. It was still running good when I got rid of it.

What oil are you running? If you go to an oil that flows better during a cold start such as 0w20 or 0w30 the lifter will pump up faster.

Right now I have 70 dollars worth (LOL!!!) of pretty fresh Royal Purple 5w30 in the motor, so I'm not going to change it out for 0w30 just yet.

BTW, since I mostly use the car for racing, I use the 30 weight...

How many hours of a job should it be to replace all the lifters on the passenger side head?

If u are going to replace your lifters replace all of them. It took me a couple hours doing all of the myself. Do youself a favor and buy the valve spring compressor and dont get it stuck in the head lol

Thanks for the info.

I had a bad lifter in my driver's side head and had all those replaced when I was putting my forged motor together. Now about 5000 miles later I think I've got one going bad on the passenger side. I only have about 55000 miles on the car, but I race it pretty hard.

Should I put some heavier valve springs in at the same time (doing both heads obviously)??? I've got new stock valve springs, using Comp 262 cams.
I wind the motor out to 6500 rpms at the dragstrip and would like to rev it out a touch more.

I had a slight ticking noise on startup, then the idler pulley started whining. When I changed it the tick was gone.

Many of us have ran a car with a lifting ticker, but since the lifter is not fully pumping up then there is always the chance something could happen. If your changing cams or on a new motor do not pump up the lifters cause this can cause a valve to stay open during the starting cycle resulting in low compression on one or more cylinders which is detrimental to the break in on a new motor or Camshaft. I would suggest replacing all your lifters.
