Omar,

 

Do you think the coolant leak is coming from the NPT threads into the head ? What did you seal those threads with ? I'm about to do the coolant mod and am trying to figure what's best to seal the threads. I was considering just using blue silicone as I've used that before to seal badly damaged threads or using blue locktite.

 

Do NOT use silicone on NPT threads. Teflon tape, paste or both. Get something decent if you don't have it already. On the tape, wrap opposite of what you would think initially so it lays it down rather than bunching up when threaded together. Thicker higher quality tape does work better and there are stainless specific formulas when needed.

I'm with Dave here. Don't use silicone on threads. The white thread sealant I've been using has been great. I use the liquid one and make sure it's slightly tacky before threading like the instructions say.

I really think it's just that npt to an adapter not being tightened enough. The problem was it was only leaking once it got really hot on the long drives once the coolant gets really hot and thinner, so I hadn't noticed it on my shorter test drives.

Assorted small purchases over the past month or two as we slowly prepare for winter work:

 

OEM Rear main seals - might not manage these over the winter but they'll at least be available.

OEM oil pan gasket

Horn pad retaining ring (see recent post for details, mine's been cracked and the horn button falls between legs on hard bumps)

Differential axle clip - realized my right side is missing. Not sure if it stuck to the half shaft and I didn't notice unlike the other one which stayed in the diff, but needed new one.
Pinion Seal for diff - splattering fluid all over my nice stainless exhaust and gunking up the underside of the tunnel

 

Skillard shim kit - includes door latch striker shims,  inspection cover shims (actually necessary for me), door hing shims, rear hatch shims (super grateful for these because the actual oem ones seem integrated and I've just had the hinges right over the gaskets).

 

Skillard rear speaker brackets - kept trying to find an original to copy, but for the prices people were selling it wasn't worth it. Glad skillard made good aluminum reproductions for both sides. Still debating on which receiver to use and whether or not to bother creating a 3D printed bracket for a single or double din to replace the original.

 

Skillard door handle backers - I very very carefully pull down and out every single time I use my door handles to get in because the small amounts of flex are enough to get the top of the handle to rub the paint when I'm opening the door. I need to open up the back to slightly bend and fix the passenger side lock rod anyway, so i figured I'd get these along with the batch of new parts. 
 

No oil cap gasket yet. Still debating if I buy the cheap seal, or use this as an excuse to get some more bling for the engine bay with an all new oil cap. At some point I need to powder coat the valve cover soon.
