Re: saab 9-5, oil lamp flickers, post Headgasket Posted by JustinHiFi [Email] ![]() ![]() In Reply to: saab 9-5, oil lamp flickers, post Headgasket, VTfred, Sat, 14 Feb 2009 17:57:40 Members do not see ads below this line. - Help Keep This Site Online - Signup |
There is not much during the headgasket job that could be related to low oil pressure after its all buttoned back up. The only thing I can think would be if you removed the camshafts and did tighten down the caps causing the oil to leak out of where the cams seat in the cylinder head.
To start, I would suggest dropping the oil pan and just inspecting the pickup screen. Replace the pickup O-ring and also the oil delivery pipe O-rings as well when you have it down. When resealing the pan, use Anaerobic gasket sealant. If you use another type of sealant which dries up solid, you run the risk of small chunks of the sealant being squeezed out into the oil pan and getting lodged in the pickup. The anaerobic sealant will stay soft and will work its way out in an oil change or into the filter.
If this does not cure the problem, check the oil pump gears for wear. I have had multiple cases with 9-3 and 9-5s where the oil pumps are below spec and have caused lower than spec oil pressure.
