Greetings, all:
I have a serious problem with the 86GT. Summer 2017 while drilling out a broken water pump bolt, I drilled into the water jacket and of course coolant flooded out. The repair included a sealant and a time-cert thread repair. Actually worked fine until about a week ago. Timing cover gasket is now green instead of blue- the part that sticks out and is visible. And coolant is seeping out the passenger side valve cover. Clearly a head gasket failure and aforementioned hole failure.
I need advice- the engine was rebuilt about seventeen yeas ago and only has 80,000 miles on it. Plus the compression is still good. I was trying to figure out why the stat took twelve minutes to open. Now I know. I shut it off before total failure although it wasn't close to overheating.
Is it worth repair and do I need another rebuild? I know these blocks were somewhat thin to begin with so as it is already .030 over...
I'd rather just repair the hole. Its the lower of the two holes on the passenger side of the engine the timing cover/ water pump mates to.
It will need re-drilled, welded, tapped, etc. Plus the head gasket thing.
A real shame as I've repaired some minor problems like oil seeps and timing and idle issues. Last trip it ran great and was more fun than usual.
Its a keeper although not a looker. Needs painted, too.
Thoughts and ideas? Much appreciated. Other boards are just critical.
Thanks and Merry Christmas. Happy New Year as well.
Cheers.
