Thanks for the input guys- I'm a little new to this forum thing - spend most of my time in the shop making shavings. I'll fill in the profile and try to get a shorter "handle" ...and just lurk a while. There seems to be a high degree of talent here - and I respect that! Cheers!
Thank you for pointing out the limitations of "steady state" flow bench not being "real world" test - wish more folks would realize this... IMhO, its just a tool for comparative measuring, and even then one must be very careful when relating "improved" results to what actually works well on a...
Whoa up Pat! I understood it was NOT the head gasket - I understood it was a manifold gaskets, due to high boost pressure - I do not work on Detroit iron - so am not familiar with your specific app limitations - I mentioned a labyrinth type seal that uses no gasket as a likely solution - and...
to solve a similar "Patprimmer's gasket blow-out" problem on 35-40psi boosted 2.0L turbo'd motors we build, we machine a shallow mating wedge/labyrinth type sealing joint. (maybe one could use the "1948 technology" and O-ring it? BTW, we still O-Ring a lot of Honda & Mitsu blocks). At first I...
With both a dry bench and wetflow technology, we've found it's not productive to match the gasket/port, instead we will use a gasket & header opening that is about 0.050" to 0.080" larger, to create a step. On a wetflow test bench, a larger step on the long side has less effect than the one on...
