hacked521 Posted February 9, 2012 Report Share Posted February 9, 2012 just was thinking about this right now, im curious as to why l series engines lean? as in the angle the engine sits not fuel wise. does it have to do with oiling at all? :confused: Quote Link to comment
metalmonkey47 Posted February 9, 2012 Report Share Posted February 9, 2012 Hmm always thought about that. Mike explained it a while back, but I never bookmarked it. Wonder if I can find it Quote Link to comment
wayno Posted February 9, 2012 Report Share Posted February 9, 2012 Reasoning tells me that it leans away from the intake, as the napZ block is basicly the same as the L block, but leaning the other way, away from the intake, to make room for it. Quote Link to comment
I'm BLUE Posted February 9, 2012 Report Share Posted February 9, 2012 Nissan engineer fucked up the tranny shifter location ... so they had to lean it to correct it 1 Quote Link to comment
jefe de jefes Posted February 9, 2012 Report Share Posted February 9, 2012 The L series engine lean is there to compensate for the fat ass sitting in the driver seat. :mellow: Quote Link to comment
Stupid_fast Posted February 9, 2012 Report Share Posted February 9, 2012 Because it looks cool. Quote Link to comment
DISLEXICDIME Posted February 9, 2012 Report Share Posted February 9, 2012 its got the gangsta lean! So it must be because its gangsta ! Quote Link to comment
I'm BLUE Posted February 9, 2012 Report Share Posted February 9, 2012 The L series engine lean is there to compensate for the fat ass sitting in the driver seat. Lol ... Yeah ... for those who are not aware ... in s30's .... the engine crankshaft centerline is offset towards passengers side ( not perfectly centered) ... in addition to the lean towards the passengers side.

ggzilla Posted February 9, 2012 Report Share Posted February 9, 2012 It leans over so that it fits under the hood of the small cars. The first car to have the L-series was the Nissan Cedric which had enough room. But I suspect they already were looking at the tiny Datsun 510 so they made it fit both. Other engines lean to, for example most BWM engines. Quote Link to comment
datzenmike Posted February 9, 2012 Report Share Posted February 9, 2012 Leaves more room on the left for the intake manifold. The Z series leans the other way because the intake is on the other side. Quote Link to comment
hacked521 Posted February 9, 2012 Author Report Share Posted February 9, 2012 Nissan engineer fucked up the tranny shifter location ... so they had to lean it to correct it lol, thats what i was thinking. so it only has to do with room? did the nissan cedric have the l series straight up?

ggzilla Posted February 9, 2012 Report Share Posted February 9, 2012 All L-series leans over. Quote Link to comment
wayno Posted February 9, 2012 Report Share Posted February 9, 2012 lol, thats what i was thinking. so it only has to do with room? did the nissan cedric have the l series straight up? It's funny you mentioned strait up, as when I changed out my engines in the work truck, I goofed on the driverside motor mount hardware, and I mounted the engine strait up instead of leaning, I only figured it out because the steering assembly would not connect back up to the frame, as I drop it to make getting the engine out and back in easier. It looked weird sitting in there strait up, but I had not put the manifolds on yet either, and it wasn't that hard to mount that way either, I just put the bolts in the wrong holes on the drivers side.

Interesting, so the steering linkage hit the oil pan? Quote Link to comment

Ranman72 Posted February 9, 2012 Report Share Posted February 9, 2012 Its lean injection Makes the fuel flow faster to the combustion chamber :huh: Quote Link to comment
ggzilla Posted February 9, 2012 Report Share Posted February 9, 2012 It's lean beef. Er, lean rice? Quote Link to comment

datzenmike Posted February 22, 2012 Report Share Posted February 22, 2012 J H Keeerist! It's leaning to the right to make plenty of room for the manifolds, mostly the intake, on the left side. Same as the Z series is leaning to the left because the intake is on the right and the exhaust on the left takes up very little space. Quote Link to comment
TENDRIL Posted February 22, 2012 Report Share Posted February 22, 2012 L-ean series engine! :D Quote Link to comment
TENDRIL Posted February 22, 2012 Report Share Posted February 22, 2012 my motor stands straight up and down right now because i bought the wrong motor mounts, i think the right motor mounts are an inch in thickness ,... i have an 1 1/2 motor mounts.. BTW anybody know where i could buy the proper motor mounts for my L-ean series motor? Quote Link to comment
ggzilla Posted February 22, 2012 Report Share Posted February 22, 2012 There's plenty of room for manifolds without leaning it over. It is most likely leaning over for the same reason other slant engines do: to lower the top of the engine, to allow for lower hoodlines and lower the center of gravity. But you might be right. Has Nissan-Datsun ever commented on the reason? And if you can't see that L leans more than the Z, I think you must be blind! Quote Link to comment
datzenmike Posted February 22, 2012 Report Share Posted February 22, 2012 Don't forget that motor has a tiny Weber air filter. The stock one is much bigger and will be near the brake master. I used to own a slant six. :) Quote Link to comment
ggzilla Posted February 22, 2012 Report Share Posted February 22, 2012 Nice. My slant six didn't have a sexy alloy manifold and 4-bbl. Quote Link to comment
