Cleaning cylinder walls

[mreadymike]

Grandpa give me a boat and said it got really hot. I pulled the dipstick and sure enough water in the oil. Pulled the head and there is a fair amout of rust in the cylinder walls. Can I take a light sandpaper and clean this up?

reassmble, add some marvel mystery oil or seafoam to the crankcase, maybe even pour some in the spark plug holes & gas. let it run it will work it all out.. BUt my question woul dbe how all the water got in the cylinders.

Dont use sand paper yet.If it is light rust go with what boaterntexas suggests.Sanding will only make more problems for you.Charlie

Re: Cleaning cylinder walls

Failed to mention that the cause of the water was a blown head gasket. Can't detect any other cause.<br />Thanks for the suggestions

Mike, You really should hone out the cylinders to remove the rust and restore the crosshatching. If this is too much work, wipe the cylinders down with oil on a soft cloth and see how much will come off. Also try wd-40, sometimes that can remove rust. If the rust is bad the texture might crack a ring if you run it.

Re: Cleaning cylinder walls

while we are one the subject.. what exactly does the crosshatch do? hold oil to the cylinder walls, aid in compression? just curious.

Re: Cleaning cylinder walls

The cross hatch serves two purposes: one is to provide an area that lubrication can adhere to and not be wiped away with every pass of the rings, secondly it reduces the actual surface area contact that the rings pass over thereby reducing friction and heat buildup.

Hey thanks again,<br />Sprayed the cylinder walls with wd-40 and waited two days to clean, it cleaned up really nice. Bought some seafoam and will add that when I put it all back together. One other problem though, when I took out the lifters, I mixed them up. So I have no idea which one goes where and how they go in. I looked at them at there is a difference in the holes in the ends. I suspect the bigger holes face down. Any thoughts?

Hey mike. If you have an overhead cam and the valves dont go in from where you took them out of, it will put alot of wear on the cam lobes...your cam wont last very long. Dont know why, but that's what the books say. good luck

Re: Cleaning cylinder walls

I don't know what kind of engine you have, but the chances are good that the lifters are cheap. Go ahead and buy new ones.

Re: Cleaning cylinder walls

Okay, I was all wet when I said lifters. The parts I mixed up were the push rods. Same question though. Do I buy new ones or can I stick these back in randomly? You guys were probably scratching your head when I mentioned the part about the holes in the ends.

Re: Cleaning cylinder walls

All I can suggest is that you change the oil and filter again after a few hours of operation. Also , you can reuse your pushrods without concern, just so you didnt mix up the lifters. Might be a good Idea to prime the oiling system before you start it up. You can get a kit to do it at your local parts store.
