Clogged cylinders

Postby NewGoldwingOwner » Sat Jun 26, 2010 5:34 pm

I had gotten my first goldwing a couple months ago from my father in law. The stator had gone out in it and he never got it fixed. So it sat in a garage for 9 yrs :( .So I got it from him to fixed and discovered that the cylinders are clogged. I have been putting pentatrating oil in there and rocking the tire back and forth to maybe break them free.(a buddy mecanic said that was the best way.)Was wondering if anyone had any good ideas :)

Another old time trick was to put kerosene in the cylinders. It will work it's way through and just keep trying to turn it over. Is ther still anti freeze in the reservoir? What is the shape of the plugs? Any rust on them ? It will give you an idea of what has the motor locked and possibly what cylinder(s) are holding it.

Spark plugs where in good shape. no rust not even in the gas tank. still has antifreeze in reservoir. I don't know alot about motors but i know enough to get the job done. i still have to change the stator, so if it would help to take motor out to get the cylinders stuck then thats another option? Thanks

don't you have to pull the motor to change the stator?
if so just pull the jugs and do a ring job it wil need to be done anyhow you can't have rust on the internal parts of the engine

Since it looks like you have a gl1200 there is an alternative to the stator replacement. do searches for a Poorbooy alternator conversion...

Just a thought on your frozen engine pull the valve covers and loosen the valve adjustment and see if it will turn over a little ways I have found that stuck valves in engines that have sat for a long time will keep it from turning over. It may not be the rings that are stuck only a valve or two. You can then shoot some penetrating oil on the valve stem and GENTLY TAP on the stem and watch and see if they are moving and the springs are returning them to the seat.

I'd strongly advise you attack the frozen cylinders first... before spending any money on the stator. You might find out that the engine is too far gone and then it might be money wasted.... buying the stator I mean.

I'd also hold off on pulling the heads off since it's a lot easier to fill the cylinders with lubricant through the spark plug holes. You can't access the rings/pistons by pulling the heads since the cylinders are part of the engine block. Case splitting is required to access the rings/pistons... something I don't think you want to tackle at this point.

Another way to help rotate the engine would be to remove both cam belt covers and use a socket and prybar on the front crank bolt. Be sure to rotate the bolt firmly but gently and make sure the plugs are out when trying.

The operative words here are 'Gently!' and 'Patience!' Whichever way you use to turn it do it a tiny bit at a time, then turn back and get some more lube down there. Let it sit for a while (like a day or two) then do it some more and repeat the process. There can be a significant rust ridge on the cylinders if it's been lying that long and it's very easy to break a ring on it.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!

My trick to freeing up stuck cyl's is to put brake fluid in the cyl's and let them sit for 24 hours. You have to make sure you get the brake fluid to coat the entire piston rings. They will brake loose in time. Don't rush it. You don't want to score the cyl walls! I have done this trick from eveything to R/C engines, boat motors, bikes and autos. Even a chainsaw. You just have to give it some time for the brake fluid to eat the rust.

Good Luck!

PB Blaster does a good job on rusted sticky parts. I've used it in seized up lawnmowers with good success.
