I have seen at least three oil pickups significantly clogged with excess gasket sealer, one of which was on a blown Greddy TT car. Not convinced one way or the other on the oil issue, but the excess liquid gasket that appears to come from the upper oil pan seal could have an impact on oil supply issues.

 

Subscribing.....

 

that was definately apparent in my blown motor- good point!

 

So the excess liquid gasket is from Nissan manufacturing? Aside from (partially) plugging up the oil pickup, I wonder if this can affect the oil pressure regulator or the oil pump? I'm not sure where the filter is relative to the flow of oil....

Seems like the JWT oil pan spacer might be a worthwhile mod for anyone just for the opportunity to do a bit of cleaning/inspection. BTW, the pics of the JWT pan spacer looks like it has a spacer for the oil pickup to lower it to take advantage of the new depth. Does the APS pan come with a pickup lowering spacer as well?

Thanks,
Jeff

 

The JWT spacer does have an extension for the pickup tube but I don't think the APS pan needs one as it does not add oil by increasing size vertically rather they add to extra pockets on the sides. I believe it is the same heighth of the stock pan...

 

Interesting information Lorca, no doubt this could be a cause of oil starvation and lead to engine damage though I suspect that a low engine oil level would be the more likely cause of many bearing/rod failures that we've seen reported on the forum.

Yes a 1/2'' spacer to be precise for lowering the stock oil pickup further into the hi volume APS oil pan, this ensures there's always maximum engine oil around the main oil pickup.

Peter

 

The APS oil pan does have a 1/2'' spacer for the main oil pickup as the APS air cooled baffled oil pan is not only wider than the stock Nissan oil pan it's also a 1/2'' deeper to ensure the main oil pickup has maximum engine oil coverage under exteme high load conditions, all good.

Thanks

Peter

 

I stand corrected...

 

Since a picture is worth a thousand words, comparative pictures of the APS oil pan versus the stock component have been added to the APS oil pan web page. It's actually quite surprising just how much bigger the APS pan is and the internal baffles can be clearly seen.

http://www.**************/350z/sump/sump.htm

The 1/2" spacer for the main oil pickup places the pickup right inside the circular baffles so that it is totally immersed inside that area to ensure the best possible engine lubrication.

Hope this helps.

Peter, are you saying you include a spacer where the oil pick up tube attaches to the oil pump? Really? In other words, you would have to unbolt the pickup from the oil pump, and then insert a spacer to lower the pickup in the pan.

Otherwise, no matter how big of an oil pan or oil pan spacer you have, the pick up is going to be in the same relative location to the upper oil pan.

 

That's correct gq-626. Because the floor of the oil pan is 1/2" lower than the stock component, the oil pickup must be spaced down an equal amount. This ensures that the oil pickup is always totally immersed in fresh, cool engine oil and takes advantage of the addition oil capacity delivered by the APS oil pan.

From the APS TT "fluid (oil) sub-assembly" installation instructions at http://www.**************/350z/install...TFA_01-Oil.htm the detail is shown clearly on the LHS of the installation diagram. The components themselves used for this procedure are shown on http://www.**************/350z/parts/bom.htm (items 145 - oil pickup spacer block and 146 – Viton o-rings).

Very nice...you smart AU guys are always thinking of everything.

Although we disagree on the oil stravation issue as it relates to the oil pan, I think we both agree that APS makes the best darn oil pan I have seen. Very complete.

 

Thanks for your very kind compliment Sharif and APS engineering staff did give this high volume/baffled air cooled oil pan considerable thought during the design and testing process.

I guess this comes from our extensive race car experience over many years, we've always experienced oil starvation/oil surge problems in high G conditions on sticky tyres, I guess it's better to be safe than sorry, hence the thorough engineering behind the APS oil pan.

Thanks

Peter

 

power enterprise oil pan looks good too

 

Does it have the holes drilled and threaded for the oil lines for the turbo(s) though?

 

And it doesnt have the oil pikcup spacer...and its about $200 more expensive than the APS pan.

From looking at my spare motor and the factory clearances I question if the the rods are too tight. Too little clearance reduces the cooling of the bearings the hotter the bearings get the tighter and so on until failure. In FI motors the oil is already running hotter before it get to the bearings and also must remove even more heat that is generated by the heavier loads on the bearings. The larger the clearance, the more oil flows out the sides cooling the bearing and rod structure.

ANY COMMENTS?

 

More clearance means less oil pressure as well....you can't necessarily have the best of both worlds.
