On my 01 MXZ 700 i keep blowing base gaskets. I installed Cudneys 670 piston kit so i have to stack a .8 and a .5 base gasket. I have run this flawlessly for 3 years now. I reringed the engine over the summer. On the first 50 miles i blew a base gasket. It spit it out the mag side and it was allowing it to injest coolant. I was able to get replacement parts over the weekend while on vacation. I used HI-Tak to glue the 2 gaskets together then i torqued them to spec at 21 foot lbs. I put on an easy 30 trail miles and it was fine. Then we hit the lake and ran about 10 miles or so about 80 - 100 mph. Again i spit a gasket but this time out the PTO side. Any idea's why? I know many run this set-up w/out any issues.
