What the heck is this?
Water in oil saga continues. I'm about one inch from pulling the A4.
In the meantime I run a compression test and pressurized the block. I don't have confidence in either test yet and will redo. I pulled the valve cover off. Just to the right of the right most valve? What the heck is it? Note I can't see directly so took pictures with flash on |

I can't "see" your picture but does it look like a rusted out pipe plug? A few engines have a casting "fix" from the factory as I recall.
Did your tests show maintaining pressure? Pics may just help. Dave Neptune :cool: |

Sorry i don't know why the photo didn't post
There is a metallic looking thing by the red arrow...under the rusted spring This and the plug are for the #4 cylinder. definitely something going on with #4 Compression test: the motor sounds okay when running Block pressure test: i think the home depot gauge is leaking Almost have the head off |

i put the gauge on a short length of hose and it didn't hold pressure.
There are also many reviews on the HD site which state the same Good point - I only have about half the bolts loosened - the rest are soaking in pb blaster. haven't broken the seal yet. I'll try to test it again. But i think I'm pulling it anyway This engine is on borrowed time |
the picture with the red arrow looks something like a problem that I had. If you do a search using vtbob you can see my water in oil post.
