Hey guys. So I have a n fully machined motor in my car. After my 2000 mile move from CO to FL, I have developed a lifter tick. I thought that the motor just needed a valve adjustment after its first big trip. I pulled the valve covers off and haven't found anything wrong with the rockers (comp 1.52 rollers). I am now guessing I have something wrong with the hydraulic lifters?
I just moved into an apartment and don't have a garage. So all my motor work is done overnight in a Walmart parking lot. What is you opinion on what I should do. The lifter tick is quiet but annoying.

When you say you didn't find "anything wrong with the rockers", did you actually go through the adjustment procedure for each rocker... or did you just look to see if any rocker nuts had obviously backed off?
I rotated the engine over and checked to see how loose each rocker was. None of them were loose at all. But I didn't re adjust them fully. Was way too hot and tired.

After having gone through the trouble to get that far, and especially considering you were concerned about a "tick", I think I would've re-adjusted all the rockers.
U saying I should readjust them all from scratch? Like back them out and re adjust them?
Well... yeah! How else are you going to know if they were all done right? The lifters might've been adjusted without enough pre-load, and now that the cam and lifters have broken in, there's possibly now not enough pre-load... and therefore "ticking".

In the video it's difficult to distinguish lifter "clacking" from an exhaust leak. Get a mechanics stethoscope. They practically give them away at Harbor Freight. That'll help plenty in finding the source of the noise.

I don't have a link handy, but this has been discussed lots of times here. Shouldn't be difficult to find.
When I started it today. I didn't hear it. Then I romped on the gas and it came back. I wouldn't think it's exhaust because I welded that header b4 putting the motor in. Plus its not consistent. I am going to do the full adjustment tonight. I'll let u know how it goes.
Lol. So I went to the Walmart parking lot today to get started (I don't have a garage anymore), but before I could even start the rain came and washed me out. So I said to my self I would do it later. I decided to drive to taco bell because it was close and I was hungry. I went in through the entrance and there was this huge pot hole which I didn't see due to the rain. Well my stupid belt popped off because I hit it so hard. I was wanting to replace it just had not gotten around to it. I had the new one in the car with me. I made it through the drive thru, ate, and got out of the car to change the belt. Turns out the pully bolts for the water pump backed out. 2 where missing and the other two on their last thread. I bolted them down thinking to my self I was glad I didn't loose the pully all together. Got it together and started it up. It took me a moment to realise but my lifter tick was gone. It was the damn loose pully!!!!! I ran over to home depot grabbed some new bolts and winched em down with locktite red.
Just one of those laugh it off... I am an idiot type moments. Glad the rain came.
