Engine/Transmission (1994 - 1998) Water Injection Bad Oil?

[MMcCallie]

I think I've been running my water/methanol injection too strong. When checking the oil I've found it to have white and brown goop way up the dipstick starting above where it is still black. The black may sometimes have some small water bubbles in it but I'm told that much is normal from condensation.



I've also been told that to see this white and brown goop would usually indicate a blown head gasket. I don't see any oil in my coolant and the levels of both seem stable. So I'm thinking I'm using so much water that it is getting into the engine oil, which would mean it is possibly putting out the flame and washing down the cylinders past the pistons, right? Compression was almost perfect last time I had it checked, last summer.



The windshield washer fluid I've been using makes a very nice addition in power. I've been having it start as low as 5-7 psi coming in max at about 21 psi. It makes the boost climb very quickly, turns the smoke grey, and really puts you back in the seat. I have two injectors, one medium sized, the other is huge, both going in the intake horn on the flat back side.



I've seen bubbles in my oil before but never this goo. Just happened as of this most recent oil change at a Jiffy Lube in Helena, MT where they used Shell Rotella 15-40 W. The only synthetic they had was Rotella 5-40 W so I figured it better to go with the summer oil, though I have been driving in some snow with temperatures down to 30 degrees F.



Am I using too much or just at too low a boost setting? Has anyone else noticed a change in their oil when using water/methanol injection?



Thanks,

Matt

Ya, sounds like too much water.

Some condensation can happen, but depends on how much the truck sits more than anything. Normal condensation should burn off when you drive the truck.
