Thread: Broken studs/Push Rod--> From bad Gas?

Tweet

Ok. Here's where I am now.

I'll preface this with a little background: I am not a mechanic, but have built engines several times over the years. But, it's been 5 years since I built this one. However, my personal troubleshooting inside engine problems is not extensive at all.
This problem leaves me a little paranoid.

So, as you see from earlier post, I had decided that my problem was the lifters. But, with further reading, I'm not sure. So, some questions:

Lifters
1.) Once the engine is cold, are hydraulic lifters supposed to be able to be pushed down, or solid? That is, I pulled it out, put on bench, and pressed down with a push rod. Seems solid as a rock on most of them. A few I could push down.

2.) Is this normal? From some reading I have done, they are supposed to do that...at least while the engine is running.

3.) If not normal, what would cause this? Over-revving? I didn't rev the engine too high over the weekend that I had the problem, but I won't deny that I've done that.

Regarding the suggestion of anti-pumpup lifters earlier, I had already purchased new lifters by the time I saw that suggestion. With a little further reading, it appears that I need to get different rocker components if I use anti-pumpup lifters. Although not sure. I keep reading "If you get these you need to get an adjustable rocker set". Well, of course, I consider the stock lifters adjustable.

Oiling
While I stated that my engine was oiling, as I think more about it, I am not sure it is oiling like it should. Here is what I witnessed:

When I first started it, it seemed dry for a period. I had put in oil blockers on the rockers at first to keep from throwing oil all over under the hood. Then, pulled some off. At first, it was dry. Ultimately (I'd say once the engine heated up), it did push oil up through, but it did not 'squirt' like I have witnessed in the past.

So, I'm left wondering if I have a problem with oiling or not. I really don't remember what it was like in the past when I built the engine.

BTW...I am getting good oil pressure on the guage. And the rockers do appear to be wetting good with oil.

Whatch think?
