Does anyone know where are the PCV valves location and their OE part number for a 2005 SC430? I am trying to location them and replace them. I found may be the left valve is near the motor oil fill pipe. Could someone please to verify this? I don't seem to see where the right valve is located. Thanks in advance.

 

Only one that I know of.

That's the same PCV Valve I just received from Rock Auto. It's the wrong one. Ours uses a VERY tight fitting O Ring passing through the drivers side valve cover (no threads necessary) and is held in place by sheer force. The main hose feeds off the top front of the manifold and should have a thick foam covering over 90% of the hose. Be especially careful here if you have never done this before. If your lucky the PCV Valve and O Ring pop out together. If the O Ring is severely damaged and brittle, parts of the O Ring holding the PCV valve can break off and fall inside the valve cover. Scary thought just on the PITA scale. Should have a single spring clamp at the hose/valve connection. As far as it goes, just stop at NAPA. They will give you what you need. Good luck.

Not sure what you are talking about. That is the one that fit my car. I just did it about 6 months ago. Had threads just like the one shown. I have an 06. I do not know if they are all the same.

 

guys, the 2002 & 2003 did not have threads, but sometime later, I think 2004, they changed to the threaded type

 

Thank you all for the reply. My SC is 2005 so it is threaded. OEM from Lexus is $9.78. I thought that since we have a V8, so we should have 2 PCV valves, one on each side. I am not sure how the other side vented out the pressure. May be right side is connected with a hose to the left? Thanks.

 

There’s only one crankcase, so it only needs one Positive Crankcase Ventilation valve.

 

Thank you for the clarification.
