I searched for some pointers to help me evaluate a used engine I might be considering. Couldn't find much so thought I'd put this out there to the masses & see what consensus is.
There's an L20b available that's local to me. Owner said he bought it 25 yrs ago from a guy that said it "wouldn't stop leaking" & he'd "changed the head gasket but didn't have the gasket properly aligned where the timing chain goes through". The guy who has it now said he'd "popped the head off & found the problem".
At the time, this guy had a 510 with an SSS L18 & didn't need the L20b so it sat.
Fast forward to 8 yrs ago. This guy sold his 510 & drives Fiat Spiders now. He has a decent set of 510 bumpers, a splash pan, a couple of decent front grilles...& the L20b left over from his Datsun days that he's looking to get rid of.
How can I determine the condition of the L20b if it isn't installed, hasn't run in decades & was passed down from a guy to another guy with only his word regarding its condition? Is this even possible?
I know he's motivated to get rid of this stuff & seems as though making money is not a big priority for him. Even if I got it for free...would it be worth hauling it & storing it? My crazy Datsunitis disease says "well of course it's worth it...it's a Datsun part..y'never know" but my level-headed, practical side says...eh, hold up there gal...seek wisdom from Ratsun before doing anything foolish.
Opinions/advice requested & welcome.
