case drain bolt

[Plante400]

on a 400ex there is a drain bolt on the left side on the bottom of the block.. Now i was tightening the oil plug and the whole threaded area that the bolt goes into snapped right off the block. i was dumbfounded and so was my pap what he looked at it i only had one hand on the ratchet too when this happend... no idea but just watch out for that also the oil tank drain bolt , dont tighten that too much cuz the aluminum likes to strip...
has anyone ever seen that problem witht he block drain bolt???

I bought a motor last summer that was broke off when I recieved it. Thanks to ups dropping it.

The oil tank drain bolt breaking off is not uncommon, Honda even reinforced that area on later models, starting '03 I think.

It is reccomended that the crush washers should be relaced at both locations when changing the oil.

I think those washers should be included with the oil filter replacement.

thanks alot. and they are not included with the pil filter. atleast not the fram filters i use

I don't rhink think the crush washers are included with any filter replacement. Somthing Honda should consider if they continue with this set up;) :)

i know this may sound rediculous to some, but i always torque those bolts down now. i had my bottom of the tank crease and leak oil. luckly i found it before it leaked more than a few drips. the tank i put at 14 and the case i put at 18ft/lbs

you can get them welded back on, find a place that welds aluminum and is good at it and they should have no problems welding it back on for you.
