New guy here with a 99 Taurus 180k miles and was running great till it started ticking.
First thought was a lifter, luckily on the front bank. Pulled the valve cover and went straight to the noise, #4 exhaust. I applied a bit of pressure and it seemed to quiet down, confirming my thought of the lifter.
After removing the mess around the intake and ultimately the intake itself I loosened the rocker and found the lifter appeared to be collapsed.
I removed the lifter and whilst holding it upside down, the piston came to the top. Right side up it dropped back down, about 1/8".
I pulled the intake lifter out and did the same, it didn't move. I applied pressure to it and still couldn't get it to go in. I figured it must be good.
I proceeded to check the rest of the lifters and found the exhaust lifter for #1 to be bad, like the #4.
Being broke and needing the car I figured I'd replace just the 2 lifters for now and ordered them.
While waiting on the new lifters to come in I got curious, what went bad? I removed the retainer spring and out dropped the piston, that's it I thought? No spring, no valving, nothing.
So the new lifters came in and I had to know. Took one apart and there was the spring, valve plate, etc. looked right to me.
So now I'm thinking I got the wrong lifter cause the factory lifters are different. I called the dealer and there is only one type of lifter for this engine, due to it being a high rev engine they don't have the spring type hydraulic lifters I was told, the spring type won't handle the abuse.
Do ya'll think I'd be okay to use the after market lifters for now till I can do a complete overhaul?
And how do ya prime a lifter with no spring tension?
