Valve Cover Cracked - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

DataXUnknown · 01-31-2009, 12:24 AM

Ok well today I took off the valve cover, replaced the gaskets (Blacktop SR) and put it back on, as I put it back on I dropped the rear passenger side, corner, stud/bolt thing somwhere in the back of my engine. Could not find that shit for an hour.

So I resorted to getting another bolt that fit it fine with a washer on it, tightened it down, but didn't even think twice about the correct torque. So I kept tightening it (the others all tightened and I could feel about how much torque), but this one, just kept going and actually cracked my valve cover but just in the back corner. It's a small crack, and I haven't seen any oil leak out of it, but I can smell the oil and feel air pressure coming out.

My question is, can I drive it for a little while with that? I don't know if it will hurt the engine at all because it's loosing pressure from the crankcase. Is there a temporary fix for it? Almost like a bondo type fix haha? Or do I just need to whip out another $100 bucks and buy a valve cover and get it powder coated n all that make it look prettyful...

Thanks in advance

I would be pretty careful with this, as oil can get all of over the place... Shouldn't be too much pressure so I would probably just JB weld the outside.... Shouldnt' be that much pressure in there.

you can get it welded and it should be fine. I welded my friends dsm tranny after it cracked open and we havent had any issues yet.
