No Compression

My experience with sticking valves:

Valves stick when oil or gasoline gets on the stem and turns all gummy and gooey. 9 times out of 10, it's the exhaust valves. It then gets down into the valve guide and glues the stem to the guide when the valve opens. Flushing with a good solvent and working the valve up and down may be enough to soften up the goo, otherwise you'll have to pull the sticking valves out and scrub the stems and guides if the valve spring can't overcome that gummy goo.

I used to use WD-40 until I found tried a can of Liquid Wrench. There are still a couple cans of WD-40 on the shelf. Then I tried PB Blaster that everyone raves about. Now the shelf has cans of WD-40 and Liquid Wrench.

If I were 20 miles from civilization and all I had was WD-40, I'd use it. But trust me on this Barnyard, the difference between WD-40 and PB Blaster is unbelievable. I have not tried Kroil yet, but if it gets recommended here, it is probably pretty good stuff.

Take your wife into town for lunch tomorrow and "just happened to remember I need some spray". She will be pleased you thought of her and it is a good excuse to get some "real spray stuff".

An older man once told me when my valves would stick on my 37 jpop, even while it was running, to add "transmission fluid to the gas because it was made to run on gas and kerosine"... I did what he said and had no problems after that. Now I even dump a quart in my cars gas tanks at every oil change to keep the injectors clean. Good stuff!

The leap in performance from WD-40 to PB Blaster pales in comparison to results of Kroil. Well worth ordering online. I got a couple cans of aero kroil to get me started and also got a gallon of the stuff to put in a spray bottles, oil cans, etc. With so many cubs lying around, you'll need it!!

I would have suggested PB Blaster. Keep soaking the stem of the valve just below the head. Keep cranking the engine over. Should free up shortly.

SeaFoam once you get it freed up.

I just came in from Bob (Big ol' barn) and have had success so I'm gonna... Gee Willickers! Look at all the responses I got since I left!

The valve is now returning to the closed position with very minimal effort. It still hangs up a bit, but a lot better than earlier this evening.

I've been spraying it and then coming to the house to read some of the testimonials to Bigdog while it soaked Then I'd go out to work it a little more up and down, spray it again, read some more posts, work it some more. I kept repeating this over and over (I gotta move the barn closer to the house). After using up all the WD-40 and all the light that was left in Bob (I closed the doors and sealed cracks to keep the dark out) I decided to call it a night. I'm going to let it soak overnight and hit it again in the morning. I'm off work tomorrow and I don't have any Cubs to go after so I have plenty of time.

Thanks everyone for your help. You have all been great! I gotta go read some more of the feedback to Bigdog. That should keep me busy till sun up. He deserves a great big pat on the back for all he has done for this forum. I told my wife that he made me to buy all those Cubs while she was gone. I even bought a fake arm sling to make it look more convincing.

WD-40 and PB Blaster are two different things. Each one has their purpose and serves their purpose well. WD-40 is simply a mild lubricant and moisture displacer. When I was in Marine Corps boot camp they gave it us to clean our rifles and protect against rust. PB Blaster is a penetrant that breaks up rust, gum, etc. Beyond that Kroil evidently does even better job as a penetrant.

...until I get electric to the Big Ol' Barn (Bob).

Contrary to popular belief, light bulbs do not give off light. I do not know why they are call light bulbs in the first place. What you need are "Dark Suckers" in Bob. Dark suckers suck all the darkness out of a room rather than giving off light. The more the wattage the faster they suck the darkness away.

O yeah, PS: I want to see a big fancy dark sucker over the pool table.

Jim, that was a very interesting read and it makes perfect sense (maybe my wife is on to something after all). On my way to get cans of Kroil, PB Blaster, Sea Foam, and Free All, I will swing by Home Depot and see if I can get some decent dark suckers for Bob (short for Robert - Rustic Ol' Building Enjoying Rejuvenated Timbers).

Denny, your point is well taken. I guess my view of WD-40 is a generational thing. When I was in basic, we had to sharpen our spear points with sand. The only oil we saw was in the lamps. But that was really "Old Army".

As Jim T would tell you, you sure don't want to use your dark sucker fuel.

Well Momma's still in Dallas (comes back tonight so I gotta hide all the Cubs) so I went to town for my lunch. I ordered a doubledecker on wheels and told the cute thing behind the counter I would be back to pick it (the sandwich) up.

I went over to the parts house for two sets of plugs and on the way out I saw the PB Blaster on the shelf. I grabbed two cans, went back to pay for them and headed for home. My next project will involve PB blaster.
