    spark knock? idk..noise when driving

    okay when i drive like up hills on 3rd or so...(5 speed)

    you hear like if the valves were knocking but the valves are okay? it doesn't knock regular driving..

    it will do that..unless i down shift..or w/e ?

    what could be casuing that?

    i have researched..and i heard about spark knock? what is that


    i have put in new spark plugs, oil change recently..idk what it could be..
    or if its normal

          Yeah I paid 50 from a junkyard for one. I didn't feel like pulling it or else I could have got one cheaper.

            damn..too bad the junkyards here want 70-80...for USED POS!!

            i just got autozone one for 85 something..with gasket..

            so i guess it's not too bad..

            at least i won't have to worry about it for a LONG LONG LONG LONG Time

            but the little noise is still there..

            im running 10w30 Penzoil Engine Oil...

                it's leaking from the oil drain screw..

                someone overtightened it before i bought it and now it doesn't get tight at all..
                it's fucked up..i thought about taking it somewhere to get it tap'd with a bigger hole, but the new oil pan wasn't that much...so that's what im doing..

                still doesn't fix my problem though with the little noise..

                    you sure your timing isn't off? it'll knock and ping if its off.

                      i have no clue on timing i never messed with that.. it's not really like knocking the WHOLE time..it's just certain times..
