When I first noticed it a while back it was more of a constant ticking noise. Now, it is a pretty loud.

That does not sound good.
Time to have a good look at it.
To check lifters or rockers you need to pull valve covers.
Also I would check oil pressure with a manual oil pressure gauge.
Have you got pressure?
And see if you can short out the noise by disabling one cylinder at a time.
A good trained ear can tell a lot from a noise.
Got any mechanic freinds that can listen to it?
Let us know how it goes.

I have never heard of a lifter causing a loss of power. Is it smoking at all?

[countrygirl22]

No, it's not smoking at all. We haven't got a chance to tear it apart yet. But, when we do I will update you all on what we find out! Thanks for all the help!

Hey Guys!

Been a long time, but I finally got the Blazer back on the road. Turns out it was a bad lifter. After tearing it all apart we found the bad lifter (if I get a chance I will attach a photo)...it was pretty bad. The roller in the lifter was completely gone and took part of the casing with it. Only found a few of the pieces! A new set of lifters/$200 later and she runs like a charm! Sure saved some cash doing it myself rather than bringing it in.

Thanks for all your help!

Aren't you meaning the rocker?

The stock lifters have a roller on the bottom that rides on the cam, the rockers are stamped, and do not have rollers, so it looks like countryg22 described correctly.

You are right, major brain fart here.

How did the cam lobe "not get hurt" ? if the roller was gone?

Lucky if it didn't touch the lobe. A winner.

[BlazerLT]

It might have gotten slitly scored, but I don't think it was run enough to seriously do any real damage. A lot of lubrication down there during engine operation.

One thing that shocks me is they never found the other pieces, but for some reason think they will be down in the oil pan.

Countrygirl...

Did you change the oil after this?

[countrygirl22]

BlazerLT -

I did change the oil after everything was done. I did not check it though.
