Deep gouge in cylinder wall (Page 2/2) katie80 AUG 17, 01:50 PM quote Originally posted by 82-T/A [At Work]: When you rebuild a motor, you generally want to have the cyl walls bored to an extent, along with new pistons anyway, so it's not really a huge problem anyway. I think in this case, you're probably looking at the maximum cyl bore of probably a .060 overbore. You can buy Duke .060 pistons on Rock Auto pretty inexpensively. Worst case, you have to sleeve it. Machine shop costs would normally run you about $500 for a hone / bore. If you have to resleeve it, that's probably another $300. This is just what machine work costs. You would want to do the rest. You can definitely do this. I was going to hone the cylinders and make sure they're not out of round. I won't be taking it to a machine shop, since I don't have an engine hoist anymore. I just wanted a cheap band-aid to drive the car a little longer. I don't want to spend a lot of money on fixing it, I've already spent way too much. I might just hone it more than I otherwise would to minimize the damage, and run it like that. 82-T/A [At Work] AUG 17, 01:55 PM quote Originally posted by katie80: I was going to hone the cylinders and make sure they're not out of round.

To be honest, I'm kind of surprised that it even runs like that. What do you plan to do when the engine eventually fails? katie80 AUG 17, 02:26 PM quote Originally posted by 82-T/A [At Work]: To be honest, I'm kind of surprised that it even runs like that. What do you plan to do when the engine eventually fails? part out or scrap. the frame is rotted, the paint isn't good, the interior isn't good, everything is worn out. this is AFTER all the work I already did. it had a pretty bad misfire towards the end of when I was driving it. it would die at stop lights and had no power. last time I drove it was when I moved house. this fiero was a bad monetary investment, but a good experience. learned a lot. Patrick AUG 17, 03:45 PM quote Originally posted by katie80: the water in the photo is likely just coolant from when I took the head off. I wasn't referring to the water in the photo. The pitting I mentioned earlier was from rust on the cylinder wall due to water which had been sitting on top of the piston/rings for an extended period of time. quote Originally posted by katie80: the engine was burning oil, it was probably about a quart in a month when i was driving it regularly (maybe like 1500 miles in a month). it did also have some leaks. definitely had a good amount of blow-by as well. the air filter was coated in a bit of oil most of the time from the breather. quote Originally posted by katie80: I might just hone it more than I otherwise would to minimize the damage, and run it like that. I'm not surprised the engine was going through a lot of oil. Unless the pitting and gouge is completely removed, the engine is liable to be going through the same amount of oil after reassembly. katie80 AUG 17, 06:39 PM quote Originally posted by Patrick: I'm not surprised the engine was going through a lot of oil. Unless the pitting and gouge is completely removed, the engine is liable to be going through the same amount of oil after reassembly. sorry, I thought you meant there was still water there that caused the damage. I understood what you meant. I'm not too worried about oil consumption, as long as it is less. maybe it would be good to install an oil catch can so my air filter doesn't get soaked in oil again..

Perhaps you'd be interested in this... quote Originally posted by Patrick Here: I have a 4-banger Fiero that had a heck of a problem with oil/blow-by entering the air filter canister. Oil would actually pool at the bottom of the canister. It was quite a nuisance. I had the valve cover off while doing something to the engine, and I noticed that the valve cover was baffled where the PCV breather tube plugged into it. However, this hollow chamber was obviously failing in regards to separating oil vapor from the rest of the crankcase gases. So I used a strip of metal hexmesh and folded it back and forth about half a dozen times, and positioned it securely inside this baffled area. The crankcase gases now all had to go through this multi-layered mesh before traveling up the tube and entering the air filter canister. Honestly, the results were simply unbelievable! I now find no oil in the air filter canister when previously it was pooling and needed to be drained. The hexmesh I used was similar to what is shown in this following online image. The holes are about 1/4" in diameter. katie80 AUG 18, 12:17 AM quote Originally posted by Patrick: Perhaps you'd be interested in this...
