Hello All,
I figured I would introduce myself as well as seek some advice with my first post. I recently purchased a used 1991 Lexus LS400. So far the car has been great, with a few important issues. I had to replace the fuel tank, as the seam on the original one ruptured. I am worried about the replacement doing the same, as the fuel tank seems to heavily over-pressurize. If I do not use a vented gas cap and have it in the vent position, it routinely takes 1 minute or more for the tank to release pressure when I go for a fill up. I am concerned that this pressure caused the rupture on the first tank, and it will do it to the second one.
In addition to this problem, I also seem to get a Oil warning light when traveling over 75 miles per hour. Its the amber indicator, with the oil can and the wavy lines beneath it. However, my oil level is fine, right between max and fill. Is this the oil temperature light? The previous owner used synthetic 10W30 Oil, rather than the 5W30.
Any thoughts? Thanks in advance!
Sincerely,
Jimmy The Hutt
