PS, do you have any advice on getting a taco plate to stop leaking? I'm going to remove it in the next couple of days and reexamine what else I can do. I think I'll install some mounting studs while I'm at it.
If you care to respond probably best to move this over to a PM

Often the taco plate is over tightened distorting the plate or striping out the 6mm bolt holes. The plate can often be straightened out with careful hammer work. Although I'm a proponent of using timeserts the 6mm helicoils work just fine for repairing the 6mm bolt holes. BTW every engine I have ever built I helicoil these threads no matter what condition they're in.
Other causes is damage to the Oring sealing surface of the case, I use a wire wheel and then polish with 4-600 grit paper.
I use Dow55 on the Oring when installing the plate, but in the past I've had success with the loctite liquid teflon pipe dope. Oil will work, but I've had much better success with the other two methods.
Do not over tighten, 6mm is only around 9lbs torque.
