So as part of the timing belt job in doing, I wanted to see why my intercooler was leaking oil.



I cleaned it and rigged up a simple test with some stuff I had on hand. I did have to buy the schrader tire valve. I pressured it up to 20 psi and sprayed soap solution on it and found one area that bubbled.



So I decided that before I uncrimp the tank from the core, I would try and give the tabs in the leaky area a squeeze with a pair of channel lock pliers. No more bubbles at 20 psi! I think I'll leave well enough alone for now.

Caution! 20 psi is quite a lot of pressure. More that you think. If you try this, make sure your conections are oil free and tight. DO NOT get in the way of whatever you are using to block off the inlet and outlet when you pressure up. The first try when I did this, I put the side without the schader valve over the house into my upper garden! Be very careful and sneak up on the pressure. 10 psi is probabaly enough anayway for test purposes.

Yeah, 20 psi has a kick if there is enough volume stored.

Over the house - bravo!

Thanks Steve. The Chubs post reminds me to call for a appointment. I need a couple wires in the computer moved. Over my head. Nice little drive in the country for me. As you know, I've been there twice. Derek is a whiz on this stuff. I won't mention this is on my A4. Mods will kick me off here and over to the never read swap threads. lol. No B4 no mo. Did I say that!

Drove the black B4 daily driver to multiple locations with no issues. Came out from my last stop late in the day and it would not start. Cluster lights and needles operated normally when I turned the key in ignition, but turning the key in the ignition resulted in engine doing nothing. It turns out that the starter wire plug pigtail had become unplugged. Close examination revealed that the wire clip that holds it snug and in place, was missing. Is this something to start watching for ie that the clips will deteriorate off the many connectors in the engine bay and pop off on their own, or was this a freak accident?

Haha, yeah he's not all that far from you.

Got my cluster back a few days back, have been gone for Easter so not installed yet. I also have to do a little rewiring in the cluster harness and under the hood to handle the additional led light for coolant GP activity.

New rims, replaced boot and clutch covers (thanks Redline!), re-sealed all exterior trim, sat and looked at her for an hour with beer in hand.

Changed the oil and rotated tires, replaced 2 tires and discovered an outside CV boot in my future as well as excessive play in the left inner tie rod- that one goes right to the top of the list.

Had to replace the battery in my wagon Sunday. Old one lasted 4 years and 3 months. Got some money off the $150 replacement batter - $85 out the door. Both new and old batteries were from WalMart. Size H8, biggest battery I could find. Think it is a replacement for the old Group 49 size battery. A very tight fit on the stock location.
