Repair Difficulty
Repair Time
More than 4 hours
well ,I ordered the parts i needed on a saturday,didn;t get shipped till tuesday and since it was i got to me friday

Problem fixed: leaking water from exhaust gasket

1 first removing the bolts that hold the exhaust manifold on slowly ,could strip out the threads ,spray like WD-40 on the exposied part of the tought bolts move 1/4 turn in and out ,wait about 5 or 10 mins then repeat,hopefully you won;t lose the threads. 2 this motor had 2 gaskets the 1 next to the head was leaking,carb.cleaner or brake part cleaner worked good on removeing old gasket. then i replaced the 1 that was leaking,ok .then when i started the motor the other 1 was dripping ,so to do it right had to repeat step 1 and 2 and replace 4 or 5 bolts that go into head ,all together it took about 2 weeks to get it not to leak ,thats it good luck
