The 'ol L head in goldmember is smoking more and more. Its a bluesish white smoke and it starts right at start up and dies off at idle, under any kind of load its puffing away out the back. I thought (hoped) it was just a stuck ring or two and tried flooding the cylinders with MMO but 3 of the 4 cylinders emptied within 20 sec of filling it. So it would appear that the cylinders are just wore out (guessing here). I really dont feel like pulling it right now to do a rebuild. I would do a compression test but dont have the tool to do it. My question is, is that stuff at the FLAPS on the fluid aisle called engine restorer even worth a shot or has anyone had any luck with it??
