Are the two different?

I have been having a problem with coolant puddling under the UIM between the block and LIM. I know its the stupid orings.

I pulled the turbo and UIM manifold, found my LIM gasket torn and crimped above the rear coolant oring.

When I removed the LIM, I found the oring was flattened and distroyed. i noticed two things the oring that was in there was squeezed big enough to actually rip the LIM gasket. I also found ther to be no recession on the block or LIM for the oring to sit in like the front one does.

Is the oring on the back passage different, bc I just replaces the gaskets and orings with new ones from mazda and the same **** happened the rear oring got squashed and crimped and ripped the gasket the same way and im not about to put my turbo and manifolds back on for it to do this again. Id like to stop this bs.

thanks

MY S5 turbo II is doing the same damn thing.. The problem is that mine also does not have a recession on the rotor housing.. JHB makes a new recession on the remanufactured housings. They messed up on one of my housings that came from them. Without the recession machined into the rotor housing the LIM just smashes the O-ring and leaks coolant...



Mine also leaks coolant onto the turbo manifold... https://www.nopistons.com/forums/pub...1047683358.gif

Oh Yeah!! as for the O-rings, They are the same part # from 1979 to 1995.

yeah same **** the builder used the wrong housing now I'm Just gonna get Coolant for the turbo somewhere else and eliminate the rear oring
