...cut open the filter and it looked the same. Little chunks of who-knows-what. I tried to keep the engine covered and clean while I was assembling it, but I guess you can't keep everything out... Luckily, I recognized most of it. Slivers of silicone and paint chips, mostly. Wonder where those came from...
I posted this because I never thought of swapping the oil and filter after just running it once. I thought it would be fine to wait until break in of 500 miles. A recent post someone said to warm it up and immediately drop the oil, and I am glad he said that right before I started mine up the first time. If I am a total dumb bass for posting this, I can always delete it... I was just amazed at how much stuff got in when I thought I was working in a near-contaminant-free environment... Remember, this is my first complete motor swap, so I am a newbie...
i would have left it on untill i got it ready for the road...that way you will catch all the carb. wash and all the rest of the junk in the motor...once you get it up to higher RPMs you will wash the rest of the junk out... ...JMO...
I revved it a couple times before I swapped it. Got it up to about 2500 or so, just to see how smooth it was going to run. To make sure the flywheel and balancer were doing their jobs. And to be sure it didn't decide to make any metal-to-metal sounds. Or put large holes in the side of the block, that kind of thing. Still not 6500, but at least 2500-3000 while out of gear. It is ready for the road now, as soon as I jack it up and get it off the wheel dollies. Then I can fine-tune the carb.
Oh yes I always change oil after 1 hr run time. assembly lube dust particles etc blow by untill the rings seat as Red(rip brother)always used to say cleanliness is goddlyiness(spelling) when it came to motors, especially High RPM race motors. Watched that man be so meticulous it would get boring. Glad I to got spend all that time with such a great machinist.
I don't remember who posted this tidbit of advice, but I would have never thought of it. Then I tried it, and Fish said to watch for the junk so I cut open the filter...it was amazing how much junk was in there... Luckily, it was mostly benign trash, no large metal chunks, or anything that would scare me. BUT the oil was a bit off color. Not sure if it was just full of bubbles from being freshly stirred up, or if it was already getting dark from the trash in it.
You did great! Most people who first time cut a filter,,, get scared. You will get junk and some metal. Filter cutting helps at times in seeing problems, plus I just enjoy doing it. Glad you got it running!
Filter cutting was very scary. I will never do it again. The crap I found made me worry about what MIGHT be going through my motor...
As mentioned in another post about the magnets attached to the filter, that 'stuff' won't circulate back to into your engine - the filter did it's job. And would continue to - up to a point - have I used too many dashes - sorry. FWIW, the bunch that I run with puts a few miles on the engine (race app) and then changes the oil. That might be why all our chit is broken down most the time too.
