    Pushrods had nothing but clean oil in them...it doesn't appear any rag or thread got to the top end ,nothing in the rocker boxes except a little bit clean of oil film,no threads particles at all....even when the cam chest was drained you couldn't see anything until it settled after about 1/2hr,then there were only tiny fine particles that looked like dust and not much of it,so I'm kinda on the fence about changing the lifters,especially when they told me another 30 days for the other 2 S&S ones to come in...I'm gonna cancel that order....4 S&S lifters here cost a little over $300.00 tax in,about $270.00 for stock replacements and the "B" lifter is now obsolete and I've been reading that there is a little slop in the Mexican made "C" lifter needles
    I can order Johnsons and have them here in less than a month(approx 2 weeks) for a lot less coin...

    You know,something I've thought about the last couple of days is that my oil filter got plugged pretty good and my engine was starting to starve of oil and the oil light never came on once,only when I turned on the ignition,then went out like normal.....makes me wonder would the oil light only come on at the same time I let the smoke out of the engine:confused:

    Seriously thinking about putting a pressure gauge on the bike...

    After my bulb burned out I am thinking about a pressure gauge. Probably some good insurance huh?

    The cleaning has begun....cam chest had a lot of little pieces all over it,no damage to oil pump,all passages cleaned with cans of "slap shot" an industrial cleaner/degreaser and blown out with compressed air,got jugs off, a few pieces their,so picked and cleaned and picked and cleaned...tonight gonna spray in the the case to wash the tiny pieces down to the bottom,then mity vac the crap out,then gonna flush the case with at least one 5 lire jug of motor oil to make sure all the cleaner/degreaser and cloth is out of the bottom of the case,there was only a little oil in the bottom,about 4oz's...then it's drop the oil pan and clean that out...
    Long slow tedious work,but gotta be done and we'll be sure everything is cleaned and clear,piston jets are clear and they were still in place, flywheels looked nice and polished:rolleyes:lol....pretty sure the oil filter caught 99% of the crap 'cause it's pretty heavy for an oil filter...
    Just waiting on a new set of head gaskets,hopefully will be in tomorrow,then I'll be back rollin' by the weekend with the cleanest engine on the island(inside anyway;)...

    O.K. I got lost in everything , did you find out what the pieces of metal come from.

    My buddy had pieces of metal in his motor from blowing it up.
    He tried to clean the oil tank and it would up even after cleanin, it still had metal particles in it and he got them in the new engine.
    He was told to replace the Oil tank.

    It's not metal... a small rag fell in the bottom end, got chewed up by the flywheels and oil pump and plugged the oil filter...

    shidt.... that sucks, like the doctor that left a glove in the patient.....

    I'd be concerned about the oil passages having tiny bits of cloth in them, if they
    gum up the oil path you'll be fubar'd and I'd be concerned about the bearings in the cases be sure they are rag free as well.

    YOu might as well pull the oil pan and lines and clean them all out

    YOu need to clean out the cam plate as well, if it's the newer design the
    cams float in oil in the bearings as part of the cam plate, it's going to need to be fully dissasembled and blown clean, I don't know if you can get to all the places oil flows in that plate but you need to try.

    Oil flow is from tank>pump>PSI sender>oil filter>engine>sump>return

    The question is where in that process did your rag get picked up,
    you might not find a lot in the tank but I'd want to be sure it's cleaned out
    as well as every place that is small enough that a little rag would fug up the engine, such as the piston oilers.

    It should be completely torn down, the lifters are probably good, you can remove the clip and cup and check inside, clean and reinstall spring, cup and clip to be sure, that's the only place oil would go, only issue would be if something is in a needle bearing in the lifter and it eventually goes you'll bend a pushrod, bust a valve, bang the cam, make a ton of noise. Run the Chevy lifters/Johnson..

    Check everything including the lines to the filter, and send your buddy the bill...
    He at least owes you a case of beer and a free rental during your two weeks of riding weather...

    As to the pressure sensor, if it's got pressure against it
    it's not going to light off, so if the pump is trying to get oil to the filter
    it's going by the sensor, my guess is the bypass valve opened on the filter
    and everything was just flowing in a circle so you had pressure just no filtration
    and you have ragshidt everywhere...

    You need to change your handle on the board to Rags....LOL

    LOL...Yeah I'll change the handle to "Ragtime " We contemplated splitting the cases ..but haven't done it, yet...a buddy gave us 10 cans of cleaner they use on turbines at the power plant when they're torn down for maintenance and repair, pretty high pressure for a can...then every line, passage and orifice sprayed with cleaner then compressed air....then we'll flush it with oil a few times and and make sure we got it all and oil flows everywhere

    Oh yeah,lotsa beer and cigars:D no word yet on a pole dancer lol...I almost feel sorry for him, 'cause of all the extra work he's doing now and all I'm doing is drinkin' & smokin'...
    Going through the case and cam plate again tonight,also dropping the oil pan...I would like to be able to find a diagram of the oil system to be sure there isn't a nook or cranny we missed or can't get to...like in the Evo manual,there is a large fold out diagram with red as the oil feed and blue for return...
    The rag was in with the flywheels to start and my oil filter weighs about 3 lbs now,it was plugged solid
    After tonight ,I think we'll have it cleaned out and ready to start to button it up:D

    Well....got bike back together,Keith didn't bother to check to make sure there was oil flow to the top end before he buttoned it up,he was confident enough he got everything out...
    Fired it up....sounds exactly the same .....top end rattle and not wanting to run well:wtf::angry::cussing:
    He's saying he thinks it must be the lifters aren't pumping up...:cussing:..
    I'm saying it F'n well better be:fight:
    Time for me to start throwing the junk he piled up by my Softail out of the way and finish it off,while he figures out what the :cussing: is wrong with my bike...'cause if I don't get riding very soon...:fight:

    Lifters are coming out and taken apart ...and oil flow will be verified before the covers go back on....I don't know why he would button it up without making sure oil was flowing through the top end...pushrods and tubes were cleaned and blown out...same with the block, oil pan cam chest and cam plate ...it's getting very frustrating ....lifters were the only thing not taken apart and cleaned

    did ya prime the oil pump before you reinstalled it its never gonna make a vacum in the pump if ya dont prime it . i try to always pack the pump with oil or assembly lube and fill the filter with lucas as well . prime up very fast . turn the motor over with the plugs out wtihin two or three revolutions its starts to show pressure.

    Yes sir...the pump was primed and the oil filter was filled with oil,everything was oiled as it went back together...I think he rolled the rear wheel after putting the pump in before the cam plate went on and oil shot across the garage...can't remember why he rolled the wheel,I wasn't there at the time...but I'll ask him if he re-primed the pump before the cam plate went on and centered the pump...
    When we turned the engine over with the plugs out I asked him if he could see the oil flowing:rolleyes: because I really wanted to see oil flowing through the top end before it got buttoned up...I will now though;)
    This whole fiasco is really out of character with his mechanical abilities,but so is the length of time it took to get it done....I can't help but think that if the engine went back together the night after it was taken apart,none of this would have happened,but,can't change the past so no sense dwelling on it...
    Gotta go strip it down again and hope it was just the lifters wouldn't pump up and taking them apart and cleaning them fixes it...I'll let youse know...
