rust on the cylinder walls
rust on the cylinder walls Pulled the heads off my car about a month ago and tried to clean all the fuild from everything. Apparently It wasnt good enough because I checked the engine the other day and there was surface rust on the cylinder walls and some on the top of the piston. Looked like there was some on the rings as well..
Is this a huge problem or will it just clean itself up when I start the engine.. At this point in still waiting on my heads to come in..
thanks.

Can you get a picture? The engine will still run, but any damage depends on how severe the rusting is. I always coat my cylinders with some motor oil, or atleast WD40. Id clean off what you can with a rag and some wd40. If theres no roughness or pitting (inspect very closely) I doubt your engine will even notice.
I use a marine storage spray, typically Mercury Marine since it is made to coat cylinder walls over long storage. I just did mine the other night because I am near the ocean and we have salty wet air quite a bit. I spray it in (heads are currently off the car) and then wipe it around with a clean rag. Then I turn the motor 1/4 turn and do it again. Once I have gone around twice everything including the rings is nicely coated. I would do the same in your case, don't use anything abrasive but rather get a rag and coat the cylinders good especially prior to turning it over. I wouldn't wait either.

Last year I had a new Forged block installed into my 2002 TA...my mechanic suggested that over winter storage that we coat the cyl walls and all (like descried above), to prevent rusting.
Being I spent the cash, time and pain getting the new setup last year, I figured it would be a good idea. It was def a PIA coating everything end of last summer, and just last night, we fired it up for the 1st time this year, ran it to get the oil burned out, then swapped out the plugs.
3 hours and a little blood on our hands, the job was done.
So for what its worth, might want to go the extra mile for future winter storages.
