Running in swarf
Just changed my oil after about 600 miles,there is a tiny amount of swarf in the bottom of the oil container that i drained the old oil into.
Is this normal ?

Not swarf as it long spiral bits no.
The size of the bits should only been really small thin bits about 3-5mm long, bound to be a bit of it left after machining, even with the best will/cleaning in the world, so long as it doesn't resemble bits of piston ring or shell that's normal!!

no spiral bits,very small ,you could only see metallic bits,not feel it,but there was a piece about the size of a sugar grain,but it looked like ally.I put the engine together,it was clinically clean.i was wondering if you get any of the scraping type swarf where the head nuts do up,i used long studs,and there is a washer with a ridge that you have to put in,it could possibly take a bit of ally from the head.

if standard shells were put in ,with a first gring of a crank ,(big ends),would it make any noise when running.When i built the engine,the crank was never reground as it never needed doing,it was just cleaned up by machinest.I checked all the tolerences when i put it back together,and were fine.Im starting to get paranoid,then i might go out in garage in a mo

No shells should be silent, no doubt if it needed a grind as opposed to just a polish the machine shop would have said, stop worrying, new engines can make us all paranoid you're not alone, they can also make some funny noises!

I will agree with you on that stu , i put one in mine and its amazing how much swarf was still floating about in my engine . Only small bits but it cant be good . Highly recommended for any engine .

A slither of metal that happens to be 3-5mm long won't get past the filter media, so don't know how you two think it will end up in a pressurised oil supply.
It hard to say what half the debris anyway, as it's not always obvious.
Chances are it will just sit on the sump floor until oil change washes it out.
That apart, there is no excuse for the above, it's simply bad workmanship at the end of the day.

the sump pan was pushing onto the oil strainer,which in turn was pushing the oil pipe into the big end.i have a 4x4 oil pump in a 2wd sump,i.m not sure if the 2wd strainer is shorter

its the paste action that beds an engine in.thats why you use a lesser quality oil.Years ago they used to put a paste additive in an engine to bed them in.

maybe there wasteing there time then when they spend so much time cleaning race engines over and over again so there perfect before they build them then a lol

i agree ,you dont want lumps of swarf/bits,but the oil at least will always contain metal particles,before its first oil change.The reason i got concerned was i found a hard lump the size of a grain of sugar,which was to hard to be a piece of shell.
