How Much Rubbish Should Be In First Oil Filter?

[abr33]

Hi all, new engines done about 50 kms so i pulled the filter to remove the shit that was in there from build.

I had engine as clean as i could in my workshop when i built it and iv never cut up an oil filter before so i did this time, had a fair bit of black crap in it like carbon? was some on piston tops when assembled (used old pistons, measured spot on) also there was some sparkles and a few bits of tiny paint chips, and a few bits of a metal (alloy possibly) that were prob half a mm in diameter and ultra thin, like prob a thou.

Seeing as iv never cut one up, is it normal for first filter considering i didnt assemble in a dust room?

Did u clean out the crank and all oil galleries yada yada?

Try another oil change in 50km's to test

[abr33]

Yeah crank had slugs drilled and hotwashed after it was linished.. So this is normal?

[Duncan]

umm no, it sounds poor to me. No shiney sparkles in new engines thanks.

Do you have (and replace) the oil cooler/warmer where the oil filter mounts? Did you clean and inspect the turbos?

You could always organise for an oil analysis check.

[DVS JEZ]

The only reason u should retest is because u used some 2nd hand

Parts.

As Duncan said after the next change in 50km's send an oil sample off for analysis

Didnt clean turbo out, didnt know i should? also i made the sump bigger and now i think of it some of the sparkles may be off the zinc plated hinges i used in sump? i flushed the warmer out with petrol and compressed air and i havent got oil cooler yet waiting for new one to arrive.

Do you have details of an analyser ? cheers

[BMYHOE]

depending on clearances it maybe some bearing material etc..

caterpillar dealerships do it. westrac/william adams/hastings deering etc

Well, I've killed and rebuilt a motor or 2 over the years, and I've always had more luck when the turbos are cleaned. Your whole oil system is shared with the motor, so turbo bearings, oil cooler core, standard oil warmer, oil lines, cross block oil feed etc etc etc are all suspects where the last motor's bearings can be stuck.

I use http://www.oilcheck.com.au/ for my oil analysis, they are cheap, quick, easy to deal with and happy to explain results. If you see shiney in the oil I would take an oil sample, drop and replace the oil and filter and go easy on it until the results are back.

Sorry to be suggest bad news, but the sooner you find a problem the cheaper it is

^^Listen to this man. No ones knows more about this topic.

Advice taken, I cleaned everything spotless as, but just didnt think to flush the turbo out.

Im betting on the shiney being zinc coming off the hinges i used in sump baffles and gates. And the oil on dirty side of filter had some micro sparkles, but the oil on clean side is spotlessly clean, all the crank was blueprinted and bores were all clearanced etc etc, however i had a problem when i first assembled engine cranked it till i had oil pressure, plugged up cas, fired, and holy rattly, and then squeel. Was the cam bearing squeeling running dry as head channels hadn't filled up. So i pulled cam bearing caps thinking it'd be all bound up and totalled, and it was undamaged. it had a small amount of like alloy powder type stuff that obviously wore off but i stopped it in time. I guess thats where the sparkles are from? and the bigger shiny's i think should be zinc? your thoughts? thanks for the input

[JonnoHR31]

who the hell installed your cams dry?

[JustinP]

Why wasn't assembly lube used in the bearings?

Oh dear I would be checking that out before trouble begins

[abr33]

I assembled everything in oil, but i didnt realise the head channels would take a bit to fill. As stated above i already checked the cam bearings and they were fine. still had oil on them. Obviously it wasn't good for anything but the cams and bearings were unharmed

[BMYHOE]

ive seen a car come off a run in on dyno with exactly the sparkles and shiney bits you are descirbing. when i first seen it i thought that wasnt good.

car went to make 587awkw on 30psi / E85 the same day

as above get a oil sample test done to save yourself some coin if something isnt right

[ylwgtr2]

i have a modded lpg bbq bottle that i fill with oil,pump up with air and screw into the oil pressure sender hole on the block then fill the reassembled engine with oil that way...i also tun the ignition on and ensure the light/gauge registers....its a good way of checking for oil leaks and making sure the top end ect is getting oil...i do it with the cam covers off

[DVS JEZ]

Oil is fine to use for assembly IF u are starting the engine the same dayor next

[abr33]

Jez it was a few days. I wound up till oil pressure present then fired it, but cam oil galleries were obviously still empty. Stupid but easy mistake. Please see attached pictures

The 3 dirty ones are of the filter that did the first 50 kms, the cleaner ones did the next 50. There were a few big shiny's which im near positive are zinc plating off hinges.

There was a bit of glistening in oil that was in filter, the oil in sump is spotlessly clean but. Does this look like a normal amount of shit? The black stuff feels and looks like carbon, have no idea where from though. Will still do oil analysis but is this normal?
