Hey guys, I got my first oil analysis done this last week just figured I would post the results and see what you guys think about fixing the silicon levels.

Little truck history first,
Had a remanufactured motor dropped in 8,000 miles ago. They said to change the oil after 3,000 which I did to get rid of any crap from the engine swap. They then said it would be safe to go back to the regular 5,000 mile changes. The dealer used a mopar filter and Rotella 15W40.
When I changed the oil after 3,000 I used Rotella 15W40 and a Fleetguard Filter.

After running that oil for 5,000 miles I sent in the sample. I drove a good half hour, got the engine nice and hot, tried to take the sample from the middle of the drain...all that stuff

First plan is probably to ditch that K&N filter. Not sure what to pick up though. I have read all about all the different options out there and have no idea where to start. The K&N filter was on it when I bought it so i will have to find a new one that will fit the K&N tube also. Any suggestions?

If that link does not work just let me know and I will post it again.

Thanks guys,
Alex

 

The link you posted just goes to a log-in screen.

What was your silicon level? That is usually a good indicator of dirt in the engine but not an absolute tell-all.

If you ditch the K&N let me know. I would like a spare for between cleanings. My samples come back good but there is a lot of bad mouthing of K&N filters lately.

 

K that link should work now

 

Wow!! That looks like BAD BAD NEWS. I'd get that K @ N off of there ASAP.

95 for silicon is way to high. For comparison purposes I have done over 6 different Blackstone analysis' with my AFE Stage 2 pg7 air intake and have never seen a silicon ppm reading higher than 4 ppm. Even my stock air box/filter never showed a reading higher than 8 ppm, IIRC.


..

 

Did you tell Blackstone it was a recently remanned engine? I would also recomend getting rid of the K&N, they are absolute garbage and historically known for letting tons of crap into the engine. I would recomend replacing the airfilter then put 1000 mi on the oil change, then change the oil and filter again and run it to 5000 mi then resample.

Was this a long block or a short block remanned engine?


Goodluck,


Tim

 

Agreed on the PG7 from AFE....one of only two aftermarket filters for diesels that meet oem spec. S@B progressive 8 layer is the other, IIRC. I use the PG7 as well and trust it with much confidence.

 

Yeah I mentioned the fact that it had the engine in there when I sent off the sample. They didnt say much about it though so I will call them this morning and talk with them in person. I was looking at one of the amsoil replacement filters to try out. I have a friend that really likes his. You think this would be a good place to start?? I am pretty sure the report says they replaced the engine with a reman. long block assembly. Does that make a difference?

 

I knew before I clicked on this thread that there'd be a K&N bashfest.

I've ran K&N on 4 of my diesels, and my wifes last Toyota car, and had a total of (counting on my fingers, counting, counting and thinking real hard) 0 engine failures.

Looks like this test had a contaminated sample, or there was something in there from the rebuild.

What was the cause for engine failure??

 

Yeah I didnt start this thread to start a K&N bashfest. I have used their filters in the past and have had great luck with them. I had just told a couple of other users on this forum I would sample my oil since I had one of the K&N filters on the truck and post the results. Infact, I hope this does not turn into a thread that is geared towards how poor a K&N filter performs.

here is the link on everything that happened to the engine

I called and talked to a blackstone rep. this morning. They said to re sample after 3,000 and see where the levels are.

 

For what its worth, I have been using AFE on 4 of my trucks. Really good but some tech data I can across is showing AEM is now better on flow and filtering over time. (cleaning cycles). If I can find the lab data I will post it.

 

How often do you sample your engine oil?


Tim

 

I took a class put on by one of the Chevron engineers, it was about oil and doing an oil analysis for fleets, he told us straight up ,that you could send 2 samples in on the same oil and that they could come back totally different results.depnding on the person that did the testing. we have sent in 2 oil samples taken from the same truck, and the same time, but sent them in under 2 different, truck id #'s and got back 2 different results.

 

Were the results a lot different or pretty close to the same?

 

me too... have ran K&N on a number of vehicle for 100k+ miles with great results. note they were all gas vehicles.

posted above to show... I'm well aware of K&N's great track record.

just yanked K&N off my 97 CTD after 15k miles and went back to stock filter. reason for doing so is finding dirt on turbo vanes.

if intake vanes has a layer of dirt... then dirt has to be getting into motor. have not done oil analysis, but finding dirt inside intake is good enough reason for me for me to remove K&N filter.

 

I have run K&N and always found dirt on my intake tubes... Won't ever run them again. Now I run Amsoil Nanofibers.
