Lifter tick

[GRace]

I have been running 3g lifters in my newly rebuilt engine for about 2000 miles now. A couple of them have always seemed to make a little bit of ticking. After installing a fmic, new injectors, new turbo, I idled it up to temp and everything sounded fine.

Today after fixing a fuel leak I started the car and it idled to about 160 degrees when I got a pretty loud lifter tick all of the sudden. I turned off the engine pulled the valve cover, everything looked fine. I started it up 30 minutes later and pulled the injector plugs one at a time to rule them out. While I was doing this the loud tick went away and the quiet ticking like normal continued.

It's not an injector, I think oil pressure built up enough to quiet the loud tick.

I guess my question is, how do I actually test these 3g lifters? It is not explained clearly anywhere that I have looked. I tried pushing on the lifters while they were installed in the head and they seem solid. (Oil pressure was at 40 psi when the ticking started and was at 60 when it went away the second time.)

The theory of the "3g lifters and no tick" is not all true I have seen many heads with 3g lifters that still have a little tick to them.What type of oil do you use?Did you soak the lifters in oil before installing them?

Next time you pull the head.. you may want to do this......

I use valvoline 10w-30 oil with a super tech, (walmart) filter since it has the oring seal instead of the gasket. I have switched between fram and supertech.

I did not soak the lifters before installing them. They said they were prefilled so I just dropped them in. It was probably a month before the engine actually ran with the new lifters.

I've heard about the oil port mod but I kept thinking that 3g lifters would take care of any problems...it's just wierd that the ticking got so much louder all of the sudden.

Do I need to pull the lifters or would I notice a problem just by looking at them installed in the head?

Nice! I just read your post I will definitly look into that myself.

If the head has been milled a time or three, the cross over from block to head, that trough gets shallow and will restrict the oil flow needed to fill the HLAs

Not a fan of your oil filter choice.

Supertech filters are actually one of the better filters on the market. They don't use the cardboard caps like the cheaper filters do.

Really great thread bogus.

Is it safe to run the engine with lifter tick like I have?

Spend the 15$ and get a K&N one

Should I just go after the guy I bought the lifters from? Brand new lifters shouldn't tick should they? Or at least get worse like these are doing?

I keep editing this post...I discovered that super tech filters do not use bypass valves so oil is always flowing through them restricting flow at high psi. I'll replace with a K&N filter and see if that works. It's just too coincidental that right after putting a super tech on it starts ticking so loud.

I installed a K&N oil filter and the loud tick is gone. Sounds like the Super Tech filter was restricting flow too much.

I rest my case.
