for decades I used silicone, thicker washers and to no real solution.
the return lines on the back of the head to the block always made a mess, well if you like it can be solved
the xks stainless line is just the best
they have there washer but to me ehhhhh
i went to the hardware store and finally triednylon washers
omg , bone dry
50 miles and nothing , just a wonderful fix!

 

 

I keep forgetting , no one else drives their cars?

 

Sure we do! I have lots of engine leaks, but the spot you fixed is the only place mine does not leak from

 

You get it my friend. I'm going to try a couple of oil pan bolt washers as well as well
Just to see....
But the nylon is a huge improvement.
