Default Ticking after head gasket job

Okay, here's one for you guys. I did my head gaskets a few weeks ago. Everything went fine, except there is now a ticking coming from the driver side valve cover that increases in frequency as you rev the engine.

So... I didn't touch the tappets when I was in there, but there is a chance that one of the pushrods on that side got flipped end for end as I was cleaning it, and so was put back in the right slot but upside down.

Based on Spencer's experience with Marvel Mystery Oil (it made the clicking go away), I tried an oil additive that was supposed to reduce clicking, but it seems to have done nothing. Next thing I was going to try was going the opposite direction and switching to a much heavier grade oil to take up the tolerances, but I'm really flying blind at this point.

Could flipping the pushrod have caused this? Is there anything else I can do without pulling the tappets, camshaft etc etc?

Thanks in advance,

Tor

I mean how sure are you that everything on that side went back totally right other than that one push rod. There are a whole bunch of moving parts under that rocker cover. Even if something got bumped.....I would say pop the valve cover and have a gander.

remove the intake plenum to remove the valve cover, reinstall the plenum and start the engine and allow it to warm up ( little or no oil will leak out) , once the noise starts you will be better able to pinpoint it . I went through the same situation....and the culprit ended up being a rocker arm that the steel "socket" insert for the pushrod would loosen up as it came up to temp. let us know what you find

Oh man, I've been over it in my head a million times... did everything go back in perfect? I guess what I keep thinking is that if something were seriously out there would be a serious problem... you know if one of the pushrods didn't get seated correctly, I'd be getting a misfire, etc. So I feel like if I pop the valve cover (which took me half a day last time) it's doubtful that I'll actually be able to see anything.

Does that make sense? Any ideas what it might actually be?

edit: oops, posted this without seeing last two replies. Wow, it never, ever would have occurred to me to run the car with the valve cover off. Isn't it a pressurized oil system and oil will spray everywhere like a son of a gun? I guess not, if you did it... okay, I'll definitely have to bring the camcorder along when I try this. At the very least should be good entertainment value.

edit #2: and you were already a star, spencer

I had some ticking after I did my head gaskets. Did not dawn on me that I heat tanked my heads and then did not add any lube to the rod connecting points. It did go away after a bit of running time.

Whoa. I can't believe Spencer is riding around on a motorcycle...

Anyways, I went ahead and pulled the valve cover and started the truck.

I won't tell the results, but I video taped everything for the forum's entertainment and will post in a couple of days when I edit the movie together.

It was interesting.

Loose exhaust connections like at the y pipe or manifold can give you a ticking noise. I avoid the additivies, but I did change to MAXLIFE and was amazed at the improvement in no more slight sporadic ticking or tapping, better responsiveness, better pep when you goose the throttle. And I have never had a different oil show anywhere near that improvement in so many areas.

Good Luck, We want to see that vid.

Taking quite a while to edit the video, hope there are some really juicy scenes in it.

Any hot women helping you out with the oily mess?
