Metal Shavings Behind LN IMS Bearing - Need Advice!

Just be sure that you drop the oil pan and clean everything out if you haven't already. I'd also recommend running a flush oil for a very short period. Installation of a spin on filter adapter will prevent debris from being re-introduced to the engine after it gets in the filter. Doing all of this will give you your best chances.

Thanks Charles, I have dropped the pan and cleaned everything out. I just ordered some Drei Bond to seal it back up and it should be here on Thursday. I like your idea of running a flush oil. I have a case of DT40 that I was going to put in to replace the Mobil 1 that was in it. I may just hang on to the DT40 and get some more Mobil 1 and run it for a short period and then drain. I have a few filters on hand, but they are the stock type. Can you explain to me why the spin on is better? The OEM version is much easier to inspect after an oil change.

The Spin On filter adaptor omits the factory bypass that diverts bypass oil around the filter at start up and at times of higher than normal oil pressure. During these periods the factory filter does not filter 100% of the oil. Tis is also even more true if the factory bypass spring has lost tension due to high oil temps or time in service.

The factory filter does not filter 100% of the engines oil at all times, so any debris that is suspended in the oil will take out more components. This is especially true if you are injecting debris filled oil into the IMSB.

Does this mean that using a factory filter will have a marginal increase in engine wear over the WIX type?

p.s.
Would the IMS Guardian be of value in this situation? One where you already have debris in they system however fine.
