Question about 1998 Toyota 4Runner
visible blue smoke came out of tail pipe; checked
oil level (very low); added oil (added 1 qt 5W-30 along with Motor
no more smoke (at least for now) 02/28/2009. I changed the PCV valve on
03/01/2009 but it looks like the old one I replaced is still in pretty
Background: I brought this 1998 4Runner on 02/20/2009. It passed emission without any problem. No leaks on the ground. I changed the engine oil and added gas treatment. 185 miles later, the above symptom occurred. When the oil is at the proper level, no visible smoke comes out of the tailpipe. But when the oil is low, smoke comes out. Any idea what can be wrong? Any help would be highly appreciated.
One more piece of detail to add... I also find oil inside the air filter compartment. Can just a bad PVC valve cause this? Thanks.
You might need new valve guide seals. only a trained professional show attempt.
hope this helps.
please rate good.
