  1. I live in South Florida and several weeks NOAA reported we had a 25 year rainfall ... almost 15 inches. My '92 LS 400 headliner, seats and floor got soaked. I read everything I could from this website and came up with my own plan to clear the sunroof drains. I used compressed air to blow out the drain channels in the rear. The drip hoses are located in the trunk behind the left and right side trunk panels. Once you have these panels removed, you can access the the drain hoses which exit the water to vents under the car. The drains are hard lines with spring wire clips connecting to clear drain hoses. I used compressed air to blow them out from the trunk to the roof. These drains are attached to the sun roof drains located in the rear side of the roof panel. Unless you're a trained technician, and you are absolutely sure the drain from the roof panel is actually leaking, I would not recommend attempting removing the headliner. If indeed it appears these rear drains may be clogged, you can remove the glass panel to see if there's something obstructing the flow to the rear drains. To remove the glass panel, you will have to remove the left and right glass panel plastic covers to expose the fastening screws. There is a spring clip holding this cover in the front and the back. Because there are shims on each side, you will have to remember where each shim stack needs to be replaced. Almost always the plastic covers will break toward the back and you will have to make a repair afterwards. When removing these plastic panels, use your finger nails to pry them loose rather than a tool to prevent breaking the glass. There are also two drains located in the front of the sun roof panel at each corner which run through the A pillar. I used weed whacker string to check that there were no clogs at the top side, but because these drains apparently terminate some place in the rocker panel, I wasn't sure they were completely clear because you can't see where they exit. However, I did notice that by testing with water that there were weep holes in the rocker to allow water to escape. It was here that i discovered that the rocker weep holes were crimped closed by hydraulic lifts and/or floor jacks used to hoist the car. I unbent the rocker weep holes and removed the front rubber access plugs and a subsequent water test proved that the water flowed out freely. Recently the we had another downpour and in the morning after the car was dry inside. Hope this helps.
  2. We've discussed it several times in here, you can buy a pipe plug the same thread pitch and just delete the valve completely. Won't hurt a thing, mine has been capped for three years. Just make sure to dab some RTV on the threads to seal it tight. It's pretty easy to access it without pulling the pump. Thanks. I read the article and it was very thorough, but I was thinking about replacing the valve. I can't get my hand behind the pump from the top or from under it without being a contortionist ... it's just too tight. I guess I'll take off the belt and loosen the mount bolts to move the pump out. If I don't replace the acv, can I run a loop from one nipple to the other and just clamp it off with fuel hose clamps ... its easier and less messy than putting in a plug.
  3. With intake and manifold plugged, I ran the engine for 2 minutes and ps fluid readily dripped from the open line without turning the wheel. Is there great difficulty replacing the acv?
  4. My '92 LS 400 power steering pump has been whining because fluid was blowing out of the rack seals. The rack is replaced and the pump bled, but after a half hour drive the pump is whining again. I bled and cleaned lines and checked for leaks but haven't found anything. I pulled off the vacuum lead that runs from the bottom of the ps/pump to the intake port because I noticed ps/fluid present. While it was attached to the throttle port I disconnected the air bellows side with engine running and held my finger over it ... billows of smoke came out the exhaust. I disconnected both lines and only trace smoke until it all burned off and no more smoke. I think this was the problem with losing ps/fluid. Is it okay to leave the lines disconnected? What are your thoughts? Thank you.
