Sounds like an exhaust leak, can you post a video? I do have a lot to do today/ tonight. But if you want to stop by to pick up the stethoscope I'll take a listen. Let me make sure I still have it too.

I'm not driving it in its current condition in case it is something fixing to get loose and cause a lot of damage. I'll just pop the cover and take a look for starters. If it isn't just a loose rocker, I'll take a video and post.

Drove the cobra back from santa monica with a broken rocker stud. Ron has driven a ways with a broken rocker. You'll be fine.

I don't know what it is. If an engine is making a sound it shouldn't I stop. It guarantees a potentially cheap thing doesn't get potentially expensive in a hurry.

Not all sounds are the same, if its only a few miles then I'd say you'll be ok.

Usually a loose rocker on a hydrualic cam will be louder at idle (low oil pressure) and quieter with rpm due to the rockers pumping up.

Well, it ain't the rocker. I'll take a video tomorrow night. This is kind of a bummer because I have essentially no money in the play money bucket. If it's anything serious it could get parked.

Exhaust leak is the only tick that gets louder under load. I've blown out several exhaust gaskets. Switched to copper gaskets with copper spray, zero issues for about 4 years now.

I'll stop by your place tomorrow or this weekend. Still getting home around 7?

PS, a tick aint serious. Unless youve been running it without oil and its a rod smacking around on the crank :o But that would be like NO OIL, for awhile. Otherwise dont worry.

Yes. Let me know, it'd be nice to get a second opinion. It's obviously not right whatever it is. But because it doesn't do it hardly at all when not under load, I can't easily check it myself with my head in the engine bay. :) Your help will be much appreciated.
