Which one are you wanting to check? I have left my engine sitting for over six months and it still started, and ran fine. I guess it just depends on the state of the engine as well as how and where it was stored.

Check for oil leaks as im sure you know, oil pan, under beehive, near omp, near "12A Mazda" imprint on engine (dowel pin leak). Compression check on it. Check for rust under bins and fenders if possible. See if steering is decent.

As for oil, oil starvation = dead engine

umm. thats all i have for now

Yea definetly try and do a cold start and let it warm up (cold start meaning just not have warmed up, early in morning or late at night or a surprise visit so they cant warm it up pre u getting there)

Why did he put sugar in the tank?

Sugar will normally ruin an engine.

How much is he asking for it? This sounds like beater price range (free - $1000).

sugar will only clog up fuel filters. sugar will not dissolve in gasoline.

He pulled choke pump gas tiwce and it started right up , he said he has not

started car about a week .Why cuz it started to smoke white.it smoked white for

2 minutes then it stopped. engine sounded reall good and no smoke at all even

6500 rpm it didnt smoke, my cousin and my boy in PR said it could be (spanish

word) sereno meaning like humidity and that all cuz it never did it again, i havent

bought car cuz ,he put new clutch and i guess now clutch pump went bad,I heard

is comen, let me know what you think, thanks again.

and i got him down to 950 but i think im going to tell him 800..pretty good

condition, florida car so no rust only 2 small one by back lift window, and someone

else did the sugar in tank,previous owner had some enemies i guess. .

I'd look at those rust spots near the hatch very carefully. Open the hatch and pull up the rubber seal. If its glued on it shouldn't be. The metal rim under this seal is prone to rusting away if the drain holes are not cleaned regularly. If the lip has rusted away water can run into the car instead of out the drains like it should.

you have an intresting writing style my friend. but easy to read

sounds like a good deal if it runs well and was 250 bucks. Even if the engine was all that was good on it id still call it a good deal.

Cant wait for pics and progress with any mods you end up doing
