Is there some way to flush out an engine, like if you had a bunch of metal shavings in it from the top end not getting oil? I've seen that "Motor Flush" crap in the stores but not sure if it is worth a shit. Are there any tips for this? We were just planning on changing the oil a few more times, but the engine is a 235 with the optional oil filter that only filters 15% of the oil. Could we just pull the drain plug and dump something through the motor?
The motor flush crap is just solvent that will disolve dirt and sludge. It also drops your oil pressure,because it is so thin,so you have to keep the revs up above idle. Follow the instructions on the can. [ QUOTE ] a bunch of metal shavings in it from the top end not getting oil? [/ QUOTE ] I would never put it in an engine that is in good shape,I don't give a shit what color the oil is. It is for emergency use only,sounds like you have an emergency. And find out why the top end isn't getting oil. Maybe plugged pushrods or.... something.Whatever it is,fix it. Modern oils don't develop into sludge like the old oils used to. Use the best stuff you can get to protect your valuable parts..
i know all the old guys used kerosene, and the stuff they sell to flush it with smells like kerosene as well. Coincidence? I think not.
Unk, that problem is solved (see post titled "235 top oiling problems), an absolute moron put the motor together, who knows how long it was running like that. The previous owner didn't know shit. It was a wonder that the truck didn't burst into flames from the carb leaking onto the hot exhaust manifold (Chevy 235). Whoever installed this head put the special bolt that does in a specific spot for oil to get to the rockers in the wrong place. It runs, and the consensus is that 235s can take any punishment, and the owner (Munson) will be putting a V8 in it sometime, so we just want to clean it out a bit, without going too nuts. We tried to wipe out the top of the head, where most of the shavings were, but it was no use. After we wiped it all down and started pouring the oil in (during oil change) we noticed all of the flakes pouring down. How do you make sure you get ALL of the Kerosene out? Just in case Munson decides he wants to go that route.
i put it in with the old oil, let it idle for like 15 minutes, then drained it and put in the fresh stuff.
After you are finished,put a big magnet on the side of the oil pan. The few pieces left in the motor will stick to the side of the pan and not hurt anything.
Kerosenes cheap... Dump a couple gallons throught with the drain plug out, then put the plug in, fill it with oil, run it for a few, then change the oil...
[ QUOTE ] Where would I look to find one of those? [/ QUOTE ] One magnet you could use is the ones that come on big stereo speakers. Cut off the frame of the speaker and stick it on the pan. Check with an audio store (especially automotive) for a "blown" one, they probably will give it to you.
The auto parts places sell a magnetic wrap for the oil filter but if the filter is doing only a small percentage a pan magnet is probably the best. There are also magnetic drain plugs.
get a magnet off of a microwave magnetron. very strong. any appliance repair guy will have one or two around. jerry
Go to your local farming supply store and get a Cow Magnet. They work great for oil pans. See Mel's post about Oil Monsters as to how well a cow magnet works. Mel's post -Bugman Jeff
I have a trashed speaker in the late model that should work perfectly. I'll gank that tomorrow. Thanks
