RavenDW Posted May 14, 2016 Share Posted May 14, 2016 Has anybody got a source for the different bits we find in the timing galley? The guides, chain etc. I'll probably get hold of the gaskets but I might need the other bits depending on what I find in there.

Dave6188 Posted May 14, 2016 Share Posted May 14, 2016 I don't think there has been a case of this actually damaging an engine or having any long time side effects without throwing up codes first ! if it gets to a point where they have failed, the pressure will be that low the idle will fluctuate badly and you should get intake timing control codes P0011 or P0021 or both. Reason these codes will pop up as they work off oil pressure so if you get either code or both most definitely change the gaskets as it could starve the top end of oil. If you carry on driving with these codes then good luck ! Correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...
Dave6188 Posted May 14, 2016 Share Posted May 14, 2016 Forgot to mention don't trust the gauge in your car, hot idle car gauge read 18psi and @2000rpm 50psi. I hooked a gauge upto the oil sender unit and took readings again at hot idle 15psi and @2000rpm 47psi. We calibrate hydraulic pumps, valves, rams etc at work after manufacturing them and get them certified so the accuracy of our gauges has to be spot on !

Plenty of cases of engine damage on 370s in the USA without codes and we have seen engine damage to the top end on 350 engines with low oil pressure, could be coincidence that an engine fails and just happens to have low pressure or could be a direct result I certainly wouldnt be trusting the fact that you have no codes that you have no risk of damage Quote Link to comment Share on other sites More sharing options...

I'm assuming the gaskets on mine have never been done (I don't have an FSH) and it's just hit 96k miles. It seems like the gaskets are a when rather than an if problem. Is that accurate?

The gaskets are poor quality and thats why Nissan replaced them so i would say its a case of when rather than if but some were done under the 5 yr Nissan engine warranty Quote Link to comment Share on other sites More sharing options...
RavenDW Posted May 15, 2016 Share Posted May 15, 2016 (edited) Gaskets aside, are there any parts in that region of the car that are incompatible between DEs and HRs? (offending gaskets aside obviously) So timing chains, tensioners, water pump etc. I'm doing some poking around for parts and prices right now, but I'm not having a great deal of luck anywhere except eBay (and even that's limited). Don't particularly feel like being taken for a ride price-wise by Nissan. Edited May 15, 2016 by RavenDW Quote Link to comment Share on other sites More sharing options...
Dave6188 Posted May 16, 2016 Share Posted May 16, 2016 Contacted Z1 Motorsport in America about this as they deal with the vast majority of Z's and this is what they messaged back. "We haven't ever seen significant damage caused by it, but the lack of cam timing advance really kills the performance so sometimes egos get damaged a bit. " If I knew how to upload a screenshot of my message to them and the reply I would lol Quote Link to comment Share on other sites More sharing options...

"We haven't ever seen significant damage caused by it, but the lack of cam timing advance really kills the performance so sometimes egos get damaged a bit. " What Z1 have said is correct: If the HR has low oil pressure caused by the leaking gaskets the inlet cam control is slow in responding and the idle is also a little erratic. 1 Quote Link to comment Share on other sites More sharing options...
jowen7448 Posted May 16, 2016 Share Posted May 16, 2016 So is it correct then that there is not a large risk of internal damage if this occurs? I.e if one notices a lower oil pressure then no need for immediate absolute panic if there is a reasonable level and no visible leak. Not that this is a concern for me at the moment but nice to know info ready for if and when this happens Quote Link to comment Share on other sites More sharing options...

Just be aware of the lowish oil pressure and drive accordingly until you replace the gaskets. 1 Quote Link to comment Share on other sites More sharing options...

One I recently bought an 2003 DE has the same oil pressure issue and problems related about to tackle the job. Quote Link to comment Share on other sites More sharing options...

Your car will consume oil so keep checking the oil level Quote Link to comment Share on other sites More sharing options...
