Shrapnel810

I did the swap in my 810. I went the route of bending a new pickup tube and snipping a small piece of baffle from in the pan. Wasn't to bad at all and less room for a catastrophic error...cars still running. Let us know how it goes.

Looking very badass..love how your hiding the chrome...just painting over it or peeling it all off....cause I peeled off the chrome on my Jeep grill and it was a blast!

Just an update...motor is back in the car and running tits with zero blowby....yay for me..after teardown it was obvious why it was smoking. Two pistons had broke right between the two compression rings it just tore the entire step right off about a third of the piston...so I got some new to me ones off eBay for 125. New rings and new tires for the hell of it...back on the road!

Ya I was wishing it was the answer..so I drain 1 quart at a time for 3 quarts..it didn't change anything... guess it's coming back out...

Ya, my manual for the 810 definitely says, "L24 SOHC inline 6 cylinder engine - 6 US quarts (5.7 litres) oil capacity" I have some other manuals on my PC...I'll see if they say something different..

I see. I didn't even think of that. I assumed they both would take the same amount of oil since they were the same casting, or are they not?. Is it more displacement because the piston is bigger or because stroke is longer? I did like you said though when I installed it I drained completely and refilled with 6 quarts as in my manual for the l24 then I just trimmed the dip stick till the rubber plug seated and the oil marking was still right in the crosshatch. It only needed about an inch taken off. and could you explain a bit more about this oil fog? Cause it's not actually dripping out of the breathers and it doesn't seem to be a condensed oil vapor..it seems to be burned oil smoke that is coming out..and is the test you mentioned a leak down test? It seems that it could only be blowby if it's smoking out the crankcase. What other possibilities would cause that?

I got the pan, pickup tube situated. It's the pan on the z cars and the blocks on the z cars are different then our 810. But with a rerouted oil pickup and slightly modded pan, and cutting about 1 inch off the dipstick it works...motor is in the car and running, I also know how to change my oil. But what I don't know is how to get rid of blowby...I'm going to re-ring this engine and see where that gets me...my neighbor thinks I'm a lunatic pulling the motor every other weekend...this will be the 4th time in 3 months...

OK, after thinking a bit more I've theoried up this scenario...it's not smoke from the burning gasoline in the cylinder. It's smoke from the hot combustion gasses kissing the oil in the bottom end..and I'm not seeing any smoke out the exhaust because by the time the valve opens and piston is on its way back up, all of the would be exhaust smoke has long since made its way through and around the rings..it sounds OK in my head...but maybe someone else can clear things up..and what would the peak pressure upon detonation get up to in the cylinder..cause it still seems like even 100psi would never get around even a worn out ring in the amount of time it takes the cylinder to reach bottom and the exhaust port to open.... anyway I took the rings that I put in the 240 motor to check if I had maybe cracked them or installed them funny and everything looked tight as a drum...this blowby shit makes me crazy...

So owning an old car is really a pain in the ass...I have been fucking with this thing for so long...it's nothing but a headache..I'm trying really hard to be a Datsun fan but damn its a struggle..I commend those of you who continue fixing up these fixer uppers...I have been struggling with this blow-by issue...so the 240 smoked like crazy... With new rings in it... Smoked like crazy... Now the 280 in it...smokes like crazy.....but here's the catch...why the fuck does all of this smoke come out my block and valve breathers (that is supposedly pushed past the rings) but not a single puff of smoke comes out of my tail pipe? Even with the exhaust taken off down to straight headers still I don't see any smoke...yet it billows out the breathers... Hope someone can answer me that... Cause I can't wrap my mind around it...

I think the grilles on these cars are hideous.. Looks far more aggressive with it open imo. Kinda that massaratti/ford gt air scoop type of look without them. Nice car. I like the color.

Well its in the car and runs good, has alot more pull...still wont be winning any races anytime soon but its at least tolerable to drive...just got to button up the exhaust so it doesnt sound so demolition derby.

Ya i scratched the copper pipe idea...just welded up a steel one, also had to snip out a small section of a baffle in the pan..got it on and all filled up with no leaks...but..... Now my dip stick wont work..lol dear got what will become of me without a dip stick! It should be in the car today...then just throwing on all my smog stuff..or, wait.....

So the pans and strainers are NOT a simple swap.. The 280 block is machined with the pickup in the middle of the block and the 240 has it drilled up front...so im going to have to fab something up to reroute the line up front..im thinking to use the closest size copper tubing and cut the original strainer flange off. Put in a compression fitting in between the flange and crank it down...then run the line to the bottem of the pan while clearing the cranks path. Then attach the filter or make a new one, whatever... By the way. BLM is the Bureau of Land Management...if your ever having fun out at the desert or in the middle of nowhere. These are the ones who make sure you pay a hefty fine for running over a bush...not to be confused with the "black lives matter" retards...

Well, thanks for caring...perhaps you could give me all your smog equipment?if it wont pass its not the end of the car..i have buddies out in arizona or new mexico...i can use that loophole or go find a crooked shop in otay...but its nice your looking out for me..like my own little fairy smog mother...

Well until someone buys it im going to continue to build it up the way i want it..a funny thing after dropping the pan i found out the bulge is just for the strainer.. So that's an easy workaround. But after refering to my haynes manual on the 810, they have the wrong picture of the pan on page 36...silly nissan...
