izzo Posted February 21, 2013 Report Share Posted February 21, 2013 If you want to just get it going and drive it, find another L series motor and drop it in. Can be done in 2 hours and back on the road. If you want a project, do the KA swap. many people are doing it, theres lots of documentation on it. And redeye sells the motor mounts....

datzenmike Posted February 22, 2013 Report Share Posted February 22, 2013 Whoa whoa whoa..... L motors do NOT throw rods through the block. To do that it has to have no oil lubrication. The heat welds the rod to the crank and it has no option but to snap off below the piston, it goes around and the rod top end hits the side of the block. It can't do that without making a lot of noise, a LOT of noise, before that. I don't doubt that it was hot enough for a fire. 1 Quote Link to comment
Guest Rick-rat Posted February 22, 2013 Report Share Posted February 22, 2013 I would suggest finding another L-motor if you are happy with how they perform, will be up and going faster that way Quote Link to comment

metalmonkey47 Posted February 22, 2013 Report Share Posted February 22, 2013 Wonder if the fuel pump diaphragm leaked gasoline into the oil, enough to thin out the oil to the point that it's not properly lubricating. Would explain the fire. Quote Link to comment
datsunaholic Posted February 22, 2013 Report Share Posted February 22, 2013 I'd love to see an autopsy on this. I'd actually like to DO the autopsy on it, but it's too far away. L-series just don't do that unless something was seriously wrong to begin with. Quote Link to comment

metalmonkey47 Posted February 23, 2013 Report Share Posted February 23, 2013 So this doesn't happen to a L-series, or it's very rare ... okay then, lucky me! Back to my question for you guys, what should I do next? I see izzo and Rick-rat have weighed in, and so far - no one has suggested I give up on the girl. Very rare, it only happens when something else fails or on a poor rebuild. From what I've gathered on Ratsun, bearings generally only spin when there's an oiling problem. Like gasoline thinning down the oil??? Would explain all of it IMO, from the break to the fire. I say find another L20B and get her going with another reliable motor :thumbup: Quote Link to comment
yello620 Posted February 23, 2013 Report Share Posted February 23, 2013 I say swap a VG into it.. :w00t: Quote Link to comment
wayno Posted February 23, 2013 Report Share Posted February 23, 2013 I say swap a VG into it.. :w00t: Of course you would, but would you do it again to another one? :lol: Quote Link to comment
datzenmike Posted February 23, 2013 Report Share Posted February 23, 2013 Find another L series motor. Complete. The head on this one may be compromised if there was an oiling problem. Manifolds, alt, water pump, dizzy should be fine and could be swapped onto a long block. An L20B would be a nice up grade. Did you check the oil level yet? Quote Link to comment
Dawa Posted February 24, 2013 Report Share Posted February 24, 2013 i suggest anal ♥♥♥ Quote Link to comment
yello620 Posted February 24, 2013 Report Share Posted February 24, 2013 Of course you would, but would you do it again to another one? :lol: Absolutely. But I would skip the VG30 and use a VG33 block. Quote Link to comment

darrel Posted February 25, 2013 Report Share Posted February 25, 2013 You bought the truck for the engine? I don't know what your plans are, but I would get it running in its current truck first. Quote Link to comment
Juan Valdez Posted February 25, 2013 Report Share Posted February 25, 2013 I like darrel's idea. I would get the new truck running reliably for daily driver/commuter use, and use this as an opportunity to swap out the toasted motor for a KA or something, unless you absolutely need a running truck now.

sick620 Posted February 26, 2013 Report Share Posted February 26, 2013 get them both running gets my vote 2 :) Quote Link to comment

izzo Posted February 26, 2013 Report Share Posted February 26, 2013 You know you own a Datsun when ... ... your daily driver Datsun dies, and somehow that becomes a good reason to buy another project Datsun - one that can't be driven either :angel: lolwut? Quote Link to comment
