It's only on the first start. If I leave it running after the first start it will take for a while. Possibly forever I'm not sure. What I've been doing is turning it off after a second or two and then turning it back on. That second time I start it the valve ticking is not there.
It's only coming from one of the valves.
It's had an oil leak for a while. So I don't know if the previous owner had put stop leak in it but I did. Before the last oil change though I put a can of seafoam in and let it run for about 400 miles. There's currently no oil additives in it except a half a quart of Marvel's mystery oil. The last time I change the oil, which was a few days ago, there was no debris at all in the oil, it was silky smooth.
Another potential cause of the problem is the engine used to search up to 4000 RPMs when you first start it. I cleaned out the idle air control and it's not perfect but it's a lot better now.
The part that sucks about this is I can only test it out once a day. After that second start it'll run all day long.
What do you think the problem is? Could this just be a faulty hydraulic lifter?
