Stuck Oil Pressure Relief Valve: what do I do? Posted by iveand [Email] ![]() ![]() |
Well, finally got to checking the oil pressure releif valve while changing the oil. The spring comes out, but the cylinder itself is indeed stuck -- just what I had been suspecting. I have been having an occasional oil pressure "flicker" after the engine got nice and warm and I bring it down to idle rpm's again. As a side note, this stuck valve quite possibly could be the cause/effect? of some earlier sludge problems that I had when I got the car last year.
The advice I had from a saabtech was to put the oil back in, have a helper and turn over the engine (w/ coil removed) to build up internal pressure and "pop" the cylinder out. Others have said just be careful and use some sort of pick tool to get it out. Also, should I pull the pan and check out the rest of the situation? I have wanted to, but it seems a bit much when we start talking removing the subframe crossmember and separating the exhaust manifold. Is pulling it that hard, or is that overkill?
thanks for the help. so far this board has helped me find quite a few problems before things (so far??) have gotten too bad. Hopefully prevention now will keep me going for some time.
