Oil is pouring out..I need help finding the part
I have a 1998 Boxster. One night I go to start my car, and the oil is spraying on to the drive way. After lifting the car I can see exactly where it's coming from. I was told that i needed to order a new freeze plug or expansion plug. So it turns out that wasn't the correct part. I know I'm missing some sort of cap or plug I need help finding this part.http://986forum.com/forums/uploads02...1549735623.jpg

Have you checked to see if you have oil in the coolant or vice versa? Do you have excessive smoke/steam coming out of the exhaust?
|
I haven't checked the oil or coolant and I didn't see smoke coming from the exhaust. Just oil spilling out the hole.
|
AOS may be pressuring crankcase.
|
AOS can't pressurize the crank case. It uses vacuum to lower the crank case pressure.

Mine popped out because I blocked an oil drain in the cam cover with sealant. I was replacing the solenoid on the right rear of the engine.
My guess would be that something is restricting the oil drain. Don't know about a bad AOS. Sure does make a mess, tho. |

There is a good chance that you do need to replace the camshaft expansion plug in the end of the cam pointing toward your leak. The cam/"valve"cover must come off to do this, to prevent this from happening again replace the oe plug with a pipe plug, 1/4" I think. This is a huge,"while you are in there" project so you may want to consider if you are "IN' for the long term or sell as-is now. |

This is one cause, sometimes it just comes out due to poor fitment from manufacturing. |
Update
So thanks for helping me find the cam plug. So after installing my new cam plug, I let the car idle for about 5 minutes. Everything appeared normal. Then the rpms started to rise and idle around 2000 rpms. So I check under the car and the new cam plug blew out again. What is causing the plug to keep popping out?http://986forum.com/forums/uploads02...1551318203.jpg

You're building pressure in the crank case. Sounds like at least one of two things: failed AOS. Or, I've read about an oil return passage in the cam cover that gets blocked and causes the same thing.
Have you tried removing the oil fill cap while it was running? (Before the cam plug blew out? ) Sent from my SM-G930T using Tapatalk |
No, I haven't tried removing the cap while idling. So if my AOS has failed, shouldn't I have a check engine light or something?

What's been the most common cause, in your experience? If my opinion below was way off the mark, I won't be offended if you correct me, haha. Sent from my SM-G930T using Tapatalk |

Can the digital manometer I bought for the 987 Cayman be used on the 986 Boxter? If I remembet correctly, for some reason I was not able to use it on someone's (cannot remember his name..) 986 when I help him to change the oil on his car |
the sealant on the cam cover looks heavy and non OEM.
Have you had any engine work done recently? |
