Long time member but think this is the first time i've posted ever or in a while! Just looking for some advice...

I have bad scoring on one of my cylinders due to a spark plug disintegrating and falling into the cylinder. I have taken the head off to see what the damage was and now wondering where to go from here.

-Any ideas what sort of price I would be looking at to re sleeve just one cylinder (bring the short block complete to a shop or strip it myself?)

-Can you buy just one OEM replacement sleeve?

-Is it just worth finding a short block? Car has only done 35k miles though. AP1.

Thanks in advance!

 

cheapest solution will be pull the motor, drop in a used one

 

hope you get the answer you're looking for.

do you know why the spark plug disintegrated? was it torqued too high?

 

Possible, the spark plug wasn't torque high enough.

 

Whats the ball park figure for a used f20?

 

3-4k for the long block on ebay

 

Take block to machine shop bare. Have them do a .25 overbore and hone. Install new .25 overbore pistons. Don't let spark plug fail again.
