Cylinder repair - honing, Professional or Backyard job

Post by Gannon » Fri Dec 29, 2006 11:50 am

Ive removed the heads off my ea82T and found a little corrosion in 2 of the cylinders from water has sat when the HG blew.

What should i do???

1. Remove pistons and get it honed - Profesional or at home?
2. Leave pistons in and clean up the rough patch with a honing tool (which is only in the top of the cylinder (about an inch)
3. Leave as is and hope the rings clean it up next time i start the engine:confused:


Any thoughts welcome

If you choose to hone it you will need new rings.

If it can be done with minimal honing then you shouldnt have an issue but if you are in that far you may want to consider a full on refresh?

The backyard job, you mean by that tool that attaches to a hand drill ? how precise of a job can be done with that? how easy/hard is it really?

Gannon, l'm not sure you would get away with a light hone, one of those cylinders looks pretty rusty, to echo what others have said, spend the money and get it done properly, or at the very least, if you choose to do the job yourself, remove the pistons if only to check the rings and to keep the crap your honing from getting between them, the bores will tell you what they need. By the way, if you decide to lightly hone with the pistons in, use a set of brake cylinder honing stones on the end of your honing tool instead of the cylinder type as they need to be completely seated in the bore and brake type will do this with pistons in, cylinder stones won't.

Subaru cylinders dont have much of an issue of running out of round so a hone isnt a bad option. If you have the patience you can do a very neat job but if there is major work to be done you will find that the next problem will be the pistons etc........
