Possibly a MAJOR problem

pull your head.

its not hard, wont cost you anything, and it will almost certainly point to your cause of trouble.

H22artman...so if you pull your head you dont HAVE to have it reworked? you can throw another gasket on it and ride?

[batever]

crazy idea:

fill the spark plug hole with a short bolt that won't interfere w/ the piston

disable the fuel injector for that cylinder.

now you've got a 3-cyl engine!

If the crank was bent i think you would know it...once again correct me if im wrong.

yes you would know motor would have terrible vibration. and i stick w/ the others rod and piston

A valve may have fell in, or a part of the sparkplug is bouncing around in there.

Did you try the putting something in the spark plug hole and cranking the engine by hand bro?

Let me know if theres any spare parts or anything you need I can go on a hunt in my neck of the woods. Im up in your direction every couple of weeks.

Hope you sort it out.. dont want a Maritime CB7 off the road!

Ok, so I'm about 90% sure that the piston ring came apart in there, whatever is hitting the plugs is bouncing around on top of the piston and is very small, but jagged because it's got the whole bottom of the plug banged up. Also it's smoking like crazy out the exhaust and sputters and rattles awfully. I'm very handy with cars but I don't mess around with internal components, and have a hundred more important jobs that need to be done before winter, so I wouldn't even get a chance to work on the car for a long time. I've decided to sell it for parts or easy repair, it's ready for an engine swap, hopefully I'll get enough out of the sale to buy another car. Hate to see it go, but can't fix this problem. Thanks for all the help guys

yeh i had a civic come in did the same thing...the piston prolly broke off the crank...the crank is prlly not bent or even bad.....if u need to save money just put a rod and piston in it and call it a day....ive done it, dont like to, but it can be done...providing metal in the from the piston breaking tore the cylinder walls up....in which case u really need a whole motor anyway...so think about it that way...for 500 u can take a chance, for 800 u know ur good....

Well after talking to my mechanic and telling him the symptons he agrees that the piston ring has failed and come apart, and lil pieces of it have been hitting the plugs and causing them to be damaged. He claims that changing out the piston in these is very easy, so after talking to my father we agreed that we would make this our project. I'll either replace the piston and ring, or if this piston looks ok I'll just put a new ring in. It'll be off the road for a few weeks but it'll be worth it to keep all the work I've put into it. Finally a light at the end of the dark tunnel LOL

F22As go for under $150 at the junkyard. I wouldnt expect to just replace the rings and expect the walls not to be damaged. It would be more cost effective to pick up a used motor at the junkyard.

[batever]

well that's true about the cylinder walls, but they're (him and his dad) are gonna do it themselves so once they gets the head off he can look and see if the cylinder walls are damaged, with no $$ spent, just time. It seems like a good approach.

[keycb7]

Yes. save your cb after all that work you done to it if I remember right you got like 397K miles on your motor, so just find nice low mileage engine and swap it plus you can change all belts and seals while it's out.

as long as everything checks out OK when the head is off. yep.
