andlid Posted September 23, 2009 Posted September 23, 2009 Hi guys, Changed plugs and there is was substansial oil in one of the chambers! Closest plug to the driver side (JDM mod) Here are some photos: Is this something I should be real worried about? In the photos it actually looks like it's only around the plug and nothing at the top of it... (strange?!) Anyone have any idea where this oil came from? a Quote
Martin W Posted September 23, 2009 Posted September 23, 2009 Has it been running rough? I don't like to voice fears, cos i'm not that technical, but maybe piston ring seal on 1 cylinder isn't good. Quote

I don't like to voice fears, cos i'm not that technical, but maybe piston ring seal on 1 cylinder isn't good. hope not, has been running 'fine' according to me... is there anything I could check? Might hand it in for a compression test??? A. Quote
Toon Chris Posted September 23, 2009 Posted September 23, 2009 If there was oil in the chamber it wouldn't be wet, it would have been burnt off. You probably have oil in the plug socket only and have pread it all over as you extracted the plug. I don't know if the Z can leak into the socket if a minor cover gasket goes(?) but might you have accidentally poured some oil in when topping up? IMO, whatever it is, unless your Z has been running on 5 cylinders, blowing white smoke and losing oil at a rapid rate, it won't be all that serious Quote
ZMANALEX Posted September 23, 2009 Posted September 23, 2009 Oil seal within the cam cover will be the demon here. Quote
Trev-the-Rev Posted September 23, 2009 Posted September 23, 2009 Oil seal within the cam cover will be the demon here. Second that. Change the cam cover gasket/oil seals and it should be fine. Quote
350doc Posted September 23, 2009 Posted September 23, 2009 You may find you have to change the acual cam cover, which costs a lot! Quote
andlid Posted September 23, 2009 Author Posted September 23, 2009 to cost.... thanks for the input, dont think I accendtly poured oil on that side while filling up (since its the opsite one) How can I check doc's if it's the cam cover? thanks for the input lads. Quote
ZMANALEX Posted September 24, 2009 Posted September 24, 2009 How can I check doc's if it's the cam cover? The oil seal is part of the cam cover and is unfortunately not available separately. It forms a seal at the coil pack so may be a good idea to clean up the face of the seal and the coil pack and run for a few thousand miles and check again. I have low mileage cam covers available if you require them. Alex. Quote
Husky Posted September 24, 2009 Posted September 24, 2009 is this the rubber gasket you'd be looking for. Alex: am i right in thinking this is the one i now have spare from you? Quote
ZMANALEX Posted September 24, 2009 Posted September 24, 2009 is this the rubber gasket you'd be looking for.Alex: am i right in thinking this is the one i now have spare from you? Unfortunately not mate. There are round (approx. 40mm) oil seals pressed into the cam cover. 1 seal for each spark plug / coil pack. What you have spare is the cam cover "gasket" Quote
Husky Posted September 24, 2009 Posted September 24, 2009 ah yeah, read it back now, i know which bit you mean, shame Quote
andlid Posted September 24, 2009 Author Posted September 24, 2009 Cheers lads, so is this what I'm looking to replace? Actually started thinking about a full engine rebuild... (just any excuse he...) Quote
ZMANALEX Posted September 24, 2009 Posted September 24, 2009 Correct. #4 or #8 depending on what side is required. Quote
andlid Posted September 25, 2009 Author Posted September 25, 2009 cheers, it would be side 4 that is leaking... will keep a close eye on it and if its leaking lots I'll order one of those from you mate Quote
tmJak Posted September 27, 2009 Posted September 27, 2009 I've got the same issue. Someone's looking into a cheaper fix, so I will let you know if they can sort it. Sure they will publish if they can sort anything. The rocker covers from Nissan are £349 per side + VAT and a free butt spanking. Mine are leaking either side Quote

What miles have yours done? Keep me posted what the outcome might be. Quote
