Richf Posted May 10, 2016 Share Posted May 10, 2016 Seems to be a few questions on this so thought I'd post this to try and clarify the problem The later 350Z HR 2007-2009 engine and the 370Z engines can suffer from low oil pressure at hot idle (less than 1 bar / 15psi). This is often caused by oil gallery gasket failure, Nissan improved these gaskets in 2011 and post MY2012'on 370z's should have the uprated gaskets from the factory The pics show the failed gasket.You can see where the bolt holes have elongated as the gasket gets pushed out At idle the engines oil pump cant supply enough oil to maintain a good oil pressure because a lot of oil is pouring out of the galleries back into the sump. You wont experience any oil loss but you may have a poor idle, jerky driving at low rpm and low idle oil pressure. We keep these uprated gasket sets in stock and they are available on our web site. http://h-dev.co.uk/?...sket-repair-kit To replace these gaskets we charge £799 inc vat and that includes all parts, oil and coolant If you are concerned at all we are happy to check your car and can also check the 370'z since they do not come with a factory oil pressure gauge. After fitting the new gaskets with fresh 5w30 oil we typically see 28-30psi at idle when hot 1 Quote Link to comment Share on other sites More sharing options...

HaydnH Posted May 12, 2016 Share Posted May 12, 2016 I don't suffer from this on my HR (AFAIK) but I'm tempted to get it done when Adrian finally TTs my car... I guess the parts are fairly cheap and it's the time that's the main cost? I'm guessing if the engine is out anyway for the TT kit the swap is fairly easy?

nissanman312 Posted November 18, 2016 Share Posted November 18, 2016 Is the kit that Horsham do nissan oem gaskets but uprated ? Quote Link to comment Share on other sites More sharing options...
evilscorp Posted November 18, 2016 Share Posted November 18, 2016 (edited) Nissan improved these gaskets in 2011 and post MY2012'on 370z's should have the uprated gaskets from the factory so probably oem.

W8BGS Posted July 8, 2017 Share Posted July 8, 2017 How do you check the oil pressure on the 370z? I think I might have this issue as idle is a bit erratic, car is 2010 so falls in the age range of affected cars. I'm down in Poole and it is a it of a trek to get the pressure read. I'd happily visit for the work if it did have the issue though. Thanks. Quote Link to comment Share on other sites More sharing options...
Gareth@h-dev Posted July 11, 2017 Share Posted July 11, 2017 We have made up an oil sandwich plate with an oil pressure gauge on it. We fit it and check the pressure, pretty straight forward. Let us know if we can help or you have any further questions. Thanks Gareth 1 Quote Link to comment Share on other sites More sharing options...
W8BGS Posted July 13, 2017 Share Posted July 13, 2017 Thanks Gareth, I'm booked in with you on 26th July. Quote Link to comment Share on other sites More sharing options...
Dire Posted July 14, 2017 Share Posted July 14, 2017 (edited) I am from Bristol and was wondering if this is a 1 day fix. Also being on 70k miles do you think it would be worth replacing the timing chain whilst your practically there obviously depending on whether it is slack as i drive it pretty hard ?

Jez @ H-Dev Posted July 14, 2017 Share Posted July 14, 2017 We can do it in one day but prefer to do it over 2 day if possible. We could do the chain too if you like Quote Link to comment Share on other sites More sharing options...
chase8 Posted September 18, 2017 Share Posted September 18, 2017 I think my Z suffers from this...I am too afraid to face the truth! Quote Link to comment Share on other sites More sharing options...
