Saving Old Seagulls

seized seagulls !
ive picked up a few of these old 102 s[actually the power heads]
they are well seized up[piston/bore]
ive flooded them in diesel ect,still solid
so what advice please ?
apply heat to the blocks maybe?

i had the same prob with my century, i was ready to try anything when someone suggested useing cheap cola, icouldn't beloeve it after soaking for 24 hours i turned the flywheel by hand

If your engine is siezed above the exhaust port , a canny way is to take apart an old 8COM plug , using the outer part , weld a circular piece of steel over the hole , thread this to take a grease nipple , after having applied some diesel oil , pump full of grease.
It's quite amazing how much hydraulic force that can be achieved in this manner.
I've managed to unsieze a number of engines this way , one tip , don't be in a great hurry , let the diesel , or whatever penetrating fluid you use soak well in , I've let them soak for up to a month , before applying the grease gun.

Good luck Andy.

well i like that idea!

but ill try the coke aswell

ill let em stew for a while

If you use Pepsi you wont have to de-coke the engine afterwards....

nice one!

A few weeks ag I got my hands on a 40plus which was siezed solid. I tried soaking in diesel for a couple of weeks but after much hammering with a brass drift could not shift it. I stripped down the motor until all I had left was the cylinder with the piston/conrod left in it. This enabled me to inspect the bore below the piston which seemed to be stuck TDC. After a bit of a clean up the bore didnt seem too bad but the piston looked welded in.
After reading the message from twostrokenut on these pages I knocked up one of the gadgets out of an old plug and a grease nipple, made by simply by bolting together a large washer to the plug using a 6mm roofing bolt. once this is all welded together (washer to plug/nut to washer) the bolt can be removed and a grease nipple wil screw staight in to the nut.
As I introduced the grease into the bore and built up a bit of pressure, the piston began to move effortlessly!

The engine is now a runner, so thanks go to twostrokenut

Glad I could be of help , that method has got me out of many a tight corner .
