I'm trying to figure out what's going on with my TR3 engine. Ever since
I rebuilt the engine, I've had a problem with it blowing water out into
the overflow bottle. In a 20 minute race, it will blow about a quart
into the overflow. It's also running hot. I'm not getting any water in
the oil. I'm running a solid copper head gasket and used a block sealer
after I installed the head. I also pressure tested the block and all
was fine. After the first race weekend, I checked for combustion leaks
into the radiator using a kit which has a dye in it. The dye is
supposed to change color if combustion gases are present in the cooling
system. I couldn't tell for sure whether it was changing color or not,
so I retorqued the head and treated it again with block sealer. I did
have to turn the nuts to get the torque back to 100 lb and one stud felt
a bit squishy, like it didn't want to tighten up. I gather from resent
posts, that this is abnormal. It continues to blow water out the
overflow. I think I've got a head gasket that leaks only under load,
i.e. race conditions. However, others I've talked to aren't so sure.
I'm thinking I need to pull the head to try and figure out what's going
on. Any suggestions would be appreciated.
Thanks,
Larry Young
