I have couple different permatex

Little bit of oil in the intake does not concern me a bit. Especially on an engine with very few heat cycles.

Put some permatex on the threads and move along.

I use regular permatex grey, the shit works, to each there own though.

It's not what I would call a little. I'd estimate 1/4oz of liquid in 4 of 6 heads on top of the valve. 1/4oz each, not total.

Why would it be on top. That means it leaked in after sitting, right?

But yes. Thread sealant and move on
 
I'm guessing a bit of oil film in the intake, you pulled carb, spilled some fuel, made it look worse than it really is..

If it wasn't smoking out the tailpipe like a big dog while you did have it running, I wouldn't be too concerned at this point.

That said, while you have it tore down, I'd at least pull a few springs on what you feel were problem cylinders and have a look at things..

But you did have a sealer on the rocker studs didn't you?

Yes. Arp.

@Mr. Breeze last year it definitely smoked. My brother mentioned it and I thought it was just break in. My mom was driving behind me for the first few drives and asked why is it smoking...
 
100% it was sucking oil past the threads. I see oil in the threads. Glad you fuckers are here guiding me.

Do I need to, or how do I, clean these threads after removing the studs? Acetone, mineral spirits, or just wipe and use permatex
 
I use acetone now.

EDIT: For stuff that I want to be squeaky clean like that.
I use minerals spirits for stuff that will get oil on it.
 
I feel like a spend a good portion of my life twisting up pieces of paper towel and running them through threads.
Through holes are a lot easier than blind ones...

A repair tap is pretty nice for cleaning out old sealant.

To be clear, I wasn't asking about cleaning the bolts, but the internal threads on the head

Patriot text me and made me feel retarded so I just wanted to specify 🤣

There's also an aerosol spray by LPS called No Flash. It's an electrical contact cleaner that leaves no residue. I use it on all gasket surfaces or even spots to paint. Be careful around certain plastics and it will remove paint

I would simply stuff a shop towel or something down the intake runner and use brake clean.

Now they are calling it 2BC. Whatever, it is stinky but it works! I would not use it on something you want an accurate torque value on, like a head bolt, because it is so damn sticky it might skew the readings. But rocker studs, no problem, it is all I use.

Well, to be clear, what I was saying was take a towel, wrap it on the end of a flathead screwdriver, spray it with solvent of your choice, screw the towel down in the threads and back out until clean.
