XTM XT2 help/questions

[this2myworld3]

ok so i picked up an XTM XT2 buggy with the 457 engine. However, the front bearing keeps leaking air that is obviously causing tuning and running problems. I have changed this bearing twice now and it still leaks around the outside of the bearing. I'm thinking the case somehow created a gap there. The bearings i ordered are a direct replacement according to the manual. How can i fix this? if it comes down to it and i need to replace the engine. What is the best off road racing engine to replace it with. Actually id say top 10 and ill work my budget around that. I actually have a picco .28 i just bought for my savage. I could put that in the buggy and just buy a new savage motor. so many choices. Thank you for the help

Take The Engine Out And Check It All Around For Cracks Leaks etc.

If You Still Dont Find Anything I Recomend Buying Some Engine Sealant Or Taking It To Your LHS
