high iron in oil sample

http://www.blackstone-labs.net/(w2rzi045vyscl055dxzv02yt)/oilreports.aspx?cid=H66109 trying to post lab results & comments last several oil changes.

 

it opens when I click on it, maybe this will help others. thanks for all the advice. I have scheduled to drop truck off at shop wed & maybe they can tell me something by fri or next week monday. just want to have the truck ready by the fall to go wherever, whenever.

 

truck is going in the shop today. 1 thing I noticed the coolant has a tint to it. coolant is about 4 months old. knowing the shop will dump it all & put new in, I always before dropping truck off would drain & keep the coolant for later use in several of my other vehicles. this time it did not look green like other times. looks like a reddish/green color. does that make sense?

 

well the trend is ticking up the last 6 oil changes. whatever is is it is not going away, even though it may be in the tolerable level. swaped oil plug out today, got metal on oil plug. I hope the shop can figure it all out. with the iron much higher than it has ever been, I just don't want the bearings or anything to finally give out away from home & have more things tear apart. right now it is running. I like to have it looked at in this condition. I agree I don't want the engine tore apart "hoping" to find the cause. as always my truck & freight decide my vacation time, not me. thanks folks, will post back when I know something.

 

the shop told me the reddish color is prob due to the coolant additive that was put in. never thought of that, but that additive was a purple/ red color. they are going to put pressure test on sys & check mains & bearings.

 

shop called today. after pressure test all night & more pressure testing today. they cannot find any coolant leaking or getting into the oil. there is no sign of it in oil. no milky residue anywhere. they say the mains & inserts have a date on them 09' so those are going to be replaced. since the oil cooler has never been touched , that will be rebuilt too. no more will be done until we can be sure of just what is needed. the current things being done may not need be at this time, but I consider it preventative maint. will continue to send oil samples out & keep up with changing trends.

 

could an internal seal in the water pump cause the coolant to get into the oil? maybe when the internal parts are not moving it does not leak, so pressure test would not reveal it, but when engine is running ? detroit w.p. do have 2 seals 1 for the coolant side & 1 for the oil side, is this correct? I have had the weep hole leak oil before & coolant more than once over the last 18 years, but when the internal seal on one side or the other it would always leak out the weep hole, never leaked internal from oil to coolant or vise versa. just a thought. any opinions?
