    1000 HTG stroker Oring problem
    Posted by tripplec on Sunday, March 1, 2015 4:12 PM

    My center cylinder keeps breaking the oring and loading the cylinder and center case with coolant. First couple times it kept pulling the studs but since had Iantomasi helicoil every stud and still same. I cannot get a full 660' run.

    Is there anybody that can help me fix this problem. I paid dearly for this motor and have spent lots on it since and still a piece of ***. ,

    Thanks in advance,,,,,

    Yes , domes and head covers were sent to Iantomasi and checked out, all new helicoils were installed as well. He told me everything looked good.

    If it's a sleeved motor,check the backside of the oring groove for cracking where the water jacket passage is,that area of the sleeve is unsupported and very prone to breaking.The only aftermarket cylinders worth running are nicasil,the sleeves are a constant battle.

    Yes it is a sleeved cyl. I will check that. Is there any kind of spray that would show the crack better if there is one other than ordering the special kit to find cracks.

    Thanks.

    If the oring is blowing out at the same spot each time,that is where the problem is.Some of the sleeves have the flange outside the oring groove machined off to fit inside the cylinder studs and there isn't enough metal left to hold up.Some sleeves have individual reliefs cut for the studs,either way,the oring support is weakened.The nicasil cylinders have full support aroung the oring grooves and won't leak.Be advised that HTG parts are getting hard to get as far as cylinder sleeves.
