This motor is from my friends old car. We pulled it out before he got rid of it. Now after sitting in my garage for 6 months I finally opened it up. After removing the head I found all this crap on the pistons. They look like little flakes of black chocolate . Its only in cylinders 3 and 4. There is also like a line of oil around the top of the cylinders. Is this normal?When the motor was in the car it did blow a bit of smoke but only on Vtec crossover and at red line. What could this mean? Is the motor burning oil? Would it be the rings that would do this or the head gasket? Here are some pictures of it.

I hope someone could help because I want to put this motor in my car soon. Thanks!

 

I'm thinking that you could be leaking a tiny bit of oil from the valve guide seals, and/or a small coolant leak from the headgasket.

While you've got the head off, it probably wouldn't hurt to replace all of the valve-guide seals. You'll have to take it to a machine shop to do it, but it should'nt be very expensive. After that, obviously get a new OEM headgasket and do a really good job of cleaning off the block and head mating surfaces - perhaps even get the head resurfaced while they are working on the valveguide seals.

But honestly, it doesn't look very bad at all. Who knows, that buildup could just be from running a little too rich, or just from low quality gas. I'm sure you'd be just fine only by replacing the headgasket, and cleaning off the mating surfaces really well. The cylinders don't look bad at all.

 

How would I clean it up then? Just suck it up with a vacum? lol Here's a better picture of what I was talking about:

Oh thanks for the help MrTood .

 

definitly looks like a coolant leak, hence the rust

 

Are the number 3 and 4 pistons actually deformed? Or do they just have a lot of buildup on them? You could always just take them out to make cleaning them up much easier...

 

if you wanna clean em up...

pull the pistons/rods, hone the cylinders, stick your pistons/rods in the dishwasher(dry them off and spray WD-40 right after it shuts off so they don;t rust), throw some new rings on there, and your bottom end should be good

There not deformed there is just so much crap on them.Thanks for all the help!

 

might as well replace the rings while you've got the block out all by itself.
