Who's had an engine crankcase crack?
I'm curiuos to hear how many of you have had an engine's crankcase crack, what kind of engine it was and what car it was in. Although I think I know which brand has the most failures, based on what I've heard up until this point, I'm trying to get information from other racers to see if I'm correct.
Thanks for your input

Ive cracked a case in a Hyper 8, Hyper 9 and a Tamiya. I have also had a Losi truggy and buggy, Jammin X-2 CRT and a MBX6 that I did not crack a case in. Cases cracked were a V-Spec, a Ninja JX and a Novarossi. Seems pretty random to me, not due to car designs anyway. Unfortunately, cases crack sometimes.

an os v-spec and an rb c6 blew an hole out of the bottom of the crank case. but both of them crack when i wasnt using a one piece motor mount and i havent had one crack and i have been told one piece motor mounts help prevents it from happening but i may be wrong just repeating what i have been told.

OS V Spec,(3) Jammin X-2, X-1, RB WS7 Jammin X-1, GRP .21 Tuned SH Truggy, GO .21 Losi 8T, SW.21 MBX5R,They all Break, Depending on what you do, how much you race with what engine and what the surface and track is like...we race on alot of sunbaked "concrete" tracks in the summer...

I had the big end journal break of my AxeRossi, this put the conrod through the bottom of the crank case.

I cracked a "old" vspec on the very bottom...they are netorious from the rod hitting the bottom of the case (worn crank pin/rod bushing) on the older style cases...

My GO tech 7 port. Was running on the track in practice by myself when I thought I flammed out. Brought it back to the box, and snap! Right in half.
Up until then it ran awesome. Not quite sure why it happened... Totally awesome none the less!
