I was driving my 2004 Toyota Camry on the freeway and my oil cap blew off in the far left lane. I pulled over as fast as could with a whole lot of smoke. My oil light had been on for a long while and my mistake I haven`t put any oil in a while either. What should i do? If the engine isn`t ruined.
Well the only way your oil cap would blow off like that would be from a build up crankcase pressure. Most likely your crankcase breather tube was clogged up and/or your PCV valve was stuck closed. I would get those checked out. Pray that your engine is okay because it needed a lot of pressure to get that oil cap to pop off like that! Add an engine flush additive and do an immediate oil change.
@razmigb it still cranks and moves. any idea how it would get clogged? i remember changing a hose that had broke while i was removing the exhaust manifold?? i think that`s correct term what it is. anyways it had some build up inside. last job i did was replace spark plugs.
**i might add that this tube is soft and the old one was hard. that might be of help also
Through age, the PCV does wear out and can get stuck open or closed. In your case, it was most likely stuck closed because it wasn't venting out any of the pressure building up in the crankcase. They can get clogged overtime from carbon build-up (its exposed to oil vapors). I suggest replacing that PCV valve.
@razmigb my Camry is 24v, I think it might be a little more difficult to get to. kinda makes sense that at high speed and added pressure of the new hose would pull some junk and clog that PCV. ill put some pics when i finally decide to pull that off.
@razmigb
it was all black inside. but didn`t seem to fix the problem completely it still seems to misfire quite violently.
@bonsaitrees
Black inside where? The ventilation hoses? A problem with the PCV doesn't cause misfires unless there is a clog in the lines. Maybe try installing new lines if you haven't yet. I would check the ignition coils and/or spark plugs. To see if it is a bad coil switch them around and see if the misfires moves. If not then just hope it is the spark plug or fuel injector and not a failing piston ring or valve.
I would also change out the oil if you haven't already.
