repu engine value
hey, what do you guys think the 13b 4-ports are worth? the one i have supposedly doens't work (but i bet its just low compression that can be fixed temporarily with some atf). a friend of mine wants to buy it off of me but i'm not sure what they're worth off hand. he just wants the bare block but with the dizzy and such. thanks for any help you guys can provide.

A running 'core' motor...
...is 'worth' whatever someone is willing to pay. That said, if you don't attempt to dissassemble it --running or not-- shops like Atkins, etc., will give a certain amount for them "if" it's one they want, or if you're turning it in as a core on a rebuilt one. This charge can be relatively high, compared to what I would give for a high-miles, turning oil-burner, for example...
I say $50 to $500 for an otherwise stock, running but no longer spanking-fresh 4-port '74 thru early '80's (incl. 'j-spec') 13B.
Again, rotor housings in usable to excellent re-usable condition are each worth more --as per replacement cost/value-- than anything else.
I *wish* today I'd kept everything I once had that ran!
Forget the ATF if/once it is a runner, tune it to a 'T', then invest in a can of AmsOil 'Power Foam', and use it up all at once, as per the directions. Don your respirator, fire her up, watch the cloud piss off the neighborhood, and take her on a 50 + mile freeway/backroad joyride, without delay.
Your engine will continue to improve, until it is running the best it still can, with a performance peak expected approx. 500 miles of 'spirited' driving post-treatment.
*This mandates fixing everything/tuning up well and completely/fresh quality oil and filter PRIOR to treatment!
Another oil change after the 500 miles couldn't hurt, either.
I'd also spend on a bottle of Techron concentrate for the fuel, as well.
--Just my $ 0.02 on reviving 'junk' :)

clouds galore
hey Klaus....after oil change, filter, and STP oil treatment im still clouding up the streets. its runnin strong but burning the oil to hell. any suggestions? i have an option of swapping for an '86 NA motor with low miles but not sure if its worth it. my buddy's father seems to like the old motors and wants to rebuild it but his "hands" are in high demand. any thoughts appreciated :)

You're welcome...
1.) I specified *Techron* concentrate in the bottle, for the fuel,(not the oil) --NOT STP, or anything other-- because user reports indicate Techron has the best results... possibly even 'conditioning' old, worn oil seals beneficially... (!):)
(Yes, if you're burning much oil, the oil is also getting diluted with fuel...)
2.) If your oil control rings are worn out --possibly due to improper surface re-finishing (lapping, NOT grinding!) of side housings during rebuild(?)-- it's quite possible nothing will mitigate your oil burning, other than a rebuild, IMHO.
3.) Sometimes, the specific type/viscosity of oil used can have a meaningful effect... but it sounds like your's is worn beyond that point, Stanz... just hopr you're not using anything 'too' thin/light... I'd guess you'd be wanting to try a 20W50...?
Hope this helps!
If your father has the experience... and appreciates the old-school... I'd go with the love and experience!
Personally, I don't have any experience with second-gen or newer... and I seem to recall those were prone to flooding, in stock trim... anything can be swapped; just a question of what's worth all the work... and what you really want.

"Techron"? Is there someplace I can read about that? I have used techron occasionally in the past, but usually use MMO or 2-cycle.
I usually use 10w-30 or 10w-40 (in summer) and resist going higher even on an old engine, but that's based on my old experience using too-heavy oil in piston engines (journal galling).
My 74REPU with 15k engine will flood easily when restarting in warm weather.

As I recall...
...the bottled Techron additive benefits reported consisted of anecdotal evidence, verbally transmitted...
(I heard from a friend of a friend...)
Tried it myself; seemed to help...
