Dang! Does it run yet? Lets do something about that!

First off - Testing the valve seating. I learned a few ways to test.
Here we go.

Stage 1 Valve Seal Testing involves leveling the head in a vise with a spark plug installed, filling the chamber with H20, and waiting.

Stage 2 starts the same, then I blow compressed air through the ports and look for bubbles.

Love this guys videos too.

Instead of "Ruined," as a child I would say "Ruint." This is because of "Burned" vs "Burnt."

So now nothing is ever "Burnt" to me. Everything is "Burned."

Burned vs. burnt
Burned and burnt both work as the past tense and past participle of burn. Both are used throughout the English-speaking world, but usage conventions vary. American and Canadian writers use burned more often, and they use burnt mainly in adjectival phrases such as burnt out and burnt orange. Outside North America, the two forms are used interchangeably, and neither is significantly more common than the other.

Burned is the older form. Burnt came about during a period in the 16th through 18th centuries in which there was a trend toward replacing -ed endings with -t in words where -ed was no longer pronounced as a separate syllable. Later, British writers continued to favor the newer -t forms for a handful of verbs, while North Americans went back to the more traditional -ed forms.

-Sorry for the interruption.

OK Straight to Stage 2 Valve Testing - Because stage 1 is STOOPID if you have an air compressor.


Well, Well, Well,,, NASCAR RAY.

At the very least it proves NASCAR should not be considered a sport!

JK, Exhaust is tighter than a dolphin's &$%hole.
But that intake.... no bueno!

 

[bob58o]

This tool, from HF (I'm guessing), still clearly does not work. I figured something might have changed since last time. Kidding.

There's no room to fit on opposite sides of springs.

I'm not saying those guys are dumb or anything.....but I hear some of them use Google Maps...and it just keeps telling them...."Turn left up ahead ...???"

 

[bob58o]

I'll try to post a video of me removing these Valves. Hopefully I can do it quickly.

When I put them on, I used a rag in the combustion chamber to support the valves, with the head on a table.

Wrench, Socket, Magnet....

[bob58o]

Valves are out. No video, sorry. It took me pressing on the retainer with a box wrench while a helper poked with a long magnet on a stick thing. I used a rolled up rag under the valves on the table again.

The seating surface on the intake valve appears to have cuts (rings) around the circumference. I assume this should be smoother. It seems like these are deeper than marks left from lapping, but IDK?

Pic to come next.

 

[Poboy kartman]

Bob...I don't know what to say...I've actually pulled AUTOMOTIVE valve springs with a VERY similar tool...and small engine valve springs with my fingers?

 

[bob58o]

I can use my thumbs to push the 26lb springs.

I have trouble keeping the towel under the valve and grabbing the keepers with the magnet.

Funny as it sounds. My best go at it was with the long extendable magnet thing in my mouth, the box wrench around the tip of the stem, one hand on the head, and the other hand pushing on the wrench.
Compress the spring, grab the keepers with the magnet.

It's done now and the OHV compressor tool will need to be modified for a chance for it to work.

Bob, when you lap the valves DO NOT spin them around in a complete circle. Instead work them back and forth in a half turn. That is the proper way to do it. If you keep turning them in complete circles you will grove the seats and valves increasing chances of burning a seat or valve due to the sharp grooves it creates.

Thanks. Last time, I rolled the valve lapping tool about 3" in my palm/fingers. I guessing that is about a half revolution. I'm hoping I can get a good seal by lapping alone, because I don't have access to tools for a real valve job.

 

[bob58o]

If I'm going to polish to combustion chamber, I might as well do it before I try to lap the valves.

I have the stock springs and the stock exhaust valve on. I have the SS intake on. These are the valves I will NOT use when lapping. These valves are to protect the seats when polishing.
I protected the gasket surface with a DIY cereal box "gasket"and duct tape. The cereal box's bore is smaller than the combustion chamber diameter.
