When I removed my oilpan during the rebuild (in-progress) some of the bolts had washers while others didnt, and some of the bolts were slightly different than others (some were threaded all the way to the end, some had the last mm or so smaller diameter with no threads). Is this normal? I did not notice much of a pattern to the bolts with washers, perhaps the previous owner had the pan off. Any input would be appreciated, I'd like to do it correctly when I put it back together.

No, none of the bolts are supposed to have washers. They all should be those little 10mm bolts.

they are short 6mm bolts with no washers and they have a non thraded thing at the end. there is 22 of them.

hrm, anyone know where i can get new ones for consistency sake? (other than the mazda dealer who will probably charge alot for some bolts)

junkyard? list price is about $1 each. you could also get one at osh/home depot/ lowes/ ace ect



mike

will those home depots hold up for a car. i know i have a couple bolts from home depot (top of throttle body) but is that really safe?

The trick is finding the right damn thread pattern

Pep Boys, , I would try to get some grade 8's though

i hate that https://www.nopistons.com/forums/pub...IR#>/angry.png intake bolts suck too! stupid pitch

Yeah grade 8's are a plus, a local hardware store like Ace or a Hardware supply similar to Tacoma Screw, or Vancouver Bolt (my local co's) will have or can order them (should cost about .25 each)
