Stabil I also use in my lawn mower and boat when they get put away for the winter.

I haven't checked this for a few days because of work. Wow! Glad I started this thread. I think Tim/Ted and I don't know this for fact, that possibly the valve guides might have just as you said a liner in them insted of a bronze or cast replacement. That should be something that should be addressed in a valve job or major rebuild. If you going to go through all the trouble to have a engine rebuilt, you might as well do it right. I myself do use Marvel Mystery Oil as a gas additive in my older stuff but not in my daily new cars, and have never had a problem with it, that and Stabil too for long term storage.

If planning on using that old fuel in your mower, be sure to dilute it heavily with good fuel as the intake valve(s) in that mower engine can stick just as easily as they did in the car.  Ask me how I know.  Much as I hate to do it, I no longer use old gasoline for anything but a fire starter.

I think Marvel Mysery Oil is great stuff, I have always used it in My Airplane fuel as did my Father before me, there is a major pucker factor when you stick a valve in the air.

I had the same experience after starting a low mileage rebuilt engine that had been in storage.  It ran fine for the first few starts (not driven but just run for about 20-30 min to warm up) when valves began to stick.   It pulled several of the bronze sleeves as pictured in guide #3.    Decided to have it overhauled and mechanic said to use Stabul and Marvel Mystery Oil in both gas and oil while car is in restoration.  Haven't had any problems the last 6 months, but I have concerns using additives.   Any one have opinions on using Marvel Mystery Oil to help the sticking valve issues?  J

Not just drain old gas but make sure the valvetrain is moving freely before trying to start it. If I would have done that it would have saved me lots of time in rebuilding the top end.

My wife said she would divorce me if I bought another car. It scared me so bad I only bought 3 last month!

Wow, I'm glad to read this now. I'm close to firing up my new engine, after the car's been sitting for a year. Think I'll drain the tank first. That stuff should burn OK in the lawnmower.

I agree with Ted on the fuel problem, it would be best if we could just fill up on 100LL Avgas, but that gets a bit pricey. Stabilizer is the best course if the car sits for long periods. I wouldn't think an engine with 35000 miles on it would have tight valve guides though.

It is my opinion that guides should be a little on the loose side and I don't like posative seals, it's good to get a little oil on the stems. I don't run any kind of valve seals on my engines and have never had an oil consumtion or smoking problem.

When you do have your guides replaced make sure your shop installs true "Guides" eather bronze or cast iron, but stay away from "Liners" they tend to stick and pull out with the valve.

Ted guided me through the exact same problem. My 55 Merc. sat for 2 years and when I attempted to start it, I too had bent pushrods and such. 2 year old gas and storage in an unheated garage lent itself to its demise. Nothing a top end rebuild wouldn't fix.

Ted,

       thanks for your comments, what you said does make sense. What I also thought might of happened was the clearances for the valve and valve guide might not of been right, but I think your theory is better. I know fuel doesn't last at all now a days. If its going to be a while I always put in some gas additive called Stabil, seems to work good for me.
