Smoking and rev drops (videos inside) HELP?

So this is a continuation to my PITA car/complaint threads.

I've just been gathering information since my last thread.

What I've learned:

I'm burning coolant very, very slowly.

I'm leaking oil above my timing plug cover very, very slowly.

I'm burning oil at about a quart a month or so.

My engine misfires like crazy, especially when it's cold.

The most noticeable is when I engage the clutch and my rpm's drop.

Car seems to run amazingly when I'm driving it (not at idle)

Here's a video of the rev drops:



I know a little drop is common, but this seems extreme and causes some serious misfires. Any ideas?

Here's a video of my smoke:



It's horrible on start-up and it smokes lightly constantly. I can see clouds when I accelerate quickly.

We're thinking I need to mill my head (just did a rebuild; check my other threads for info). It seems like the coolant and oil are getting through between the head and block, but not mixing? Figured my rings were good because the cylinder walls looked mint when we had the head off. Any other suggestions?

Minor oil leak:



It's mostly going down the patch outlined in yellow. We replaced the distributor seal during the rebuild.

Any ideas other than a warped head causing malfunctions? The car holds great compression and runs like a champ. It just smokes and has some real idle issues.

Thanks guys.

Other threads for additional information:

Lean exhaust, fouled plugs, and idle surge? WTF!

New Idle Issue After Rebuild (VIDEO)

...It's been a longgggg rebuild and it's making me a sad panda

Honestly I had the same problem when I first got me lude an fixing lead me no were great learning experience but the bottom line is you just need a new swap less miles less headaches

I wish it was that easy for me. This is my DD and I can't have it out of commission too long. I imagine my first swap to be full of issues. Also, I don't have the knowledge or money to swap to the h22 or anything, so I would have to get another h23 and there are zero around here. I've looked forever. It just doesn't seem like an option and I've already rebuilt this motor with new everything really :/

The rev and smoking are the only issues, it runs amazingly at throttle (minus a little smoke).

It has never died on the rev drop. It has registered nearly 0 rpm's on the tach though. That's when it misfires badly. It feels like the engine stalls momentarily sometimes, but it always catches itself. It also seems to balance out like a scale when it's going back to normal rpm's (I mean it will go above, then below, then above, then below until it hits normal range).

I've adjusted the valves 3 separate times since the rebuild. The first two, I let my friend and he did a horrible job. The last time, we both did it and not only did the car run much better, but it raised my compression considerably. I'm almost certain the valve clearance is in spec.

This is the first car I've worked on. It's like my learning car, but I'm so anal about things that I've done 99% of things right thus far. I'm learning, but competent.

EDIT: That is not the stock milage. That cluster is something I put in to replace my broken EL's. The stock engine has 27,000 less miles on it.

Re: Smoking and rev drops (videos inside) HELP?

When the engines on does it sound like you have an air leak... By any chance ...

The only sound related to air that I notice is my intake sucking it in. I've replaced all of the vacuum lines and checked by ear, with water, and with carb cleaner for a vacuum leak. I guess It's possible, but not very likely.
