Roscoe Posted November 21, 2014 Share Posted November 21, 2014 Right guys over the last couple of days I have noticed my oil pressure on idle is low. Lower than it usually is. The needle sits literally a needles width above 0 when warmed up. Oil level is fine and was changed around 2000 miles ago. I have been searching the net over the last two days and it seems over the pond they are having the exact same issue with the g35 fitted with the vq35hr. This is a link to a good write up one of them has done. His symptoms describe mine exactly. What are your opinions on this? I am going to get the oil pressure checked with an external gauge as I no our gauges aren't very accurate. http://g35driver.com/forums/attachments/g35-sedan-v36-2007-08/170001d1413220704-cause-dreaded-p0011-p0021-codes-everyone-curious-about-notes-repair-2007-vq35hr-leaking-oil-gallery-gaskets.pdf Quote Link to comment Share on other sites More sharing options...
JetSet Posted November 21, 2014 Share Posted November 21, 2014 No. not come across this before but our HR has only done 22k, what sort of mileage has yours done? Pete Quote Link to comment Share on other sites More sharing options...
Roscoe Posted November 21, 2014 Author Share Posted November 21, 2014 Mine is now on 73k used daily on an 08 plate. Quote Link to comment Share on other sites More sharing options...
JetSet Posted November 21, 2014 Share Posted November 21, 2014 Mine is now on 73k used daily on an 08 plate. Similar to the mileage when the problem arose on the G35 then. I'm sure we have other HR owners with that sort of mileage. Pete Quote Link to comment Share on other sites More sharing options...
Roscoe Posted November 21, 2014 Author Share Posted November 21, 2014 I don't believe it to be a problem with the internals bearing clearances etc as the engine runs smooth as anything no odd sounds oil burn etc. No rattles on cold start. The issue with the gaskets seems to be well known over in the states. Quote Link to comment Share on other sites More sharing options...

Drops down to around 30ish within a minute of warming up and stays between 20-30 on a normal drive, rising rapidly if I boot it. In stationary traffic with a warm engine it'll be really low, just above the minimum on the guage Quote Link to comment Share on other sites More sharing options...

Roscoe Posted November 21, 2014 Author Share Posted November 21, 2014 Mine doesn't use any oil between services. The pressure used to sit at just below 30 on hot idle and it would sit dead on 60 at about 2500 hot also. Now it's on just above 0 at idle and 60 at 3500rpm.

Tricky-Ricky Posted November 21, 2014 Share Posted November 21, 2014 (edited) Couldn't be bothered to read the whole thing, but from what I can gather, are they saying a gasket failure is the cause? and if so the only oil feed I can think of that would loose enough pressure to cause a drop like that would be the VVTI oil feed, but will have to have a look at a HR manual to tell for sure, I only have the DE, has anyone got a link to an HR manual download?

JetSet Posted November 21, 2014 Share Posted November 21, 2014 The issue with the gaskets seems to be well known over in the states. I would always keep in mind that the climate in The States is much harder on cars than here. Temperatures of 40C for days on end and freezes that often go down to -30 must put a lot of strain on the engine plus the fact that 98 RON isn't always readily available and not at all in what are known as the rocky mountain states.

Tricky-Ricky Posted November 21, 2014 Share Posted November 21, 2014 Just had a quick squint at the DE manual, and it appears that the VVTI oil feed comes through the rear to the front of the timing chain case from the head using spigots and "O" rings and not gaskets, so unless one of these has failed and is venting oil internally to the chain case, or externally from the case to head interface, there is no other place to loose a lot of oil pressure apart from thought the head gasket itself, unless of course there is a serious bearing problem somewhere.

ATTAK Z Posted November 21, 2014 Share Posted November 21, 2014 I used to worry about oil pressure in the Zed ... now I haven't got any gauges in the CLK and so I don't worry at all ... it tells me when oil level is getting low so I just wait till that comes up ! simples ! 1 Quote Link to comment Share on other sites More sharing options...

You just have to find the right balance between having a nice drive whilst concentrating on the road, occasionally glancing at the guages, or constantly watching the guages expecting something to happen, therefore spoiling your drive. I often get asked, "Why have you got a voltmeter?". "To see if the alternators working", I tell em. "Don't need one of them in my car, and my cars got an alternator", they say.

ATTAK Z Posted November 21, 2014 Share Posted November 21, 2014 In my day it was the more gauges the better ... also Motorola push button radios ruled ... and electric aerials, and steering wheel gloves, and big Lucas reversing lights, and fake leopard skin seat covers, and switches ... we loved switches even if they weren't connected to anything ... ha ha those were the days Quote Link to comment Share on other sites More sharing options...

From a cold start it's up around 120, and once fully warm it's 60 at 2000 rpm. Mine's done 43k. Quote Link to comment Share on other sites More sharing options...
