Last year October, bad lifter number 1 cylinder. Replaced all lifters.
March this year, bad lifter number 4 cylinder, Replaced only the one lifter.
One week later now April, again number 4 cylinder intake lifter stuck closed.
WTF is going on with these things.
Bad design, Bad all the way around.
I'm on the end of the rope.

 

How many miles on the original? What are you using as replacements?

 

Truck has 90,000 miles on it right now.
I would say back in october when it first happened was a few thousand less.
I'm replacing them with OEM parts.

 

Only thing I can recommend is, soak the new lifters in the oil you are going to use. Let them "absorb" it, then install them. Done this many times in the past, kind of like a prime.

 

Thanks,
I know that's standard procedure, I can say that I never heard it put that way . I will let then "absorb"
This time I'm going to soak it, spring up, then spring down, then on it's side and roll it around a bucket a few times.
At this point I will try anything.
