Ive been plagued by blown welch plugs for some time on my rebuilt b30 engine. the engine builder here in aus put a plate to keep them in place which worked for a year however they slowly pushed their way out and started to leak. its by no means a high perfmance engine probably pushing 200hp at the crank i would like to think with a k cam.
i have found that its time for a permanent solution

i would like to check to see if anyone who has experienced this agrees that this is the correct method to solving this welch problem.
i presume that all red blocks share the same sized freeze plug. im aware that the later style was a cup and that this may cause an issue when it comes to effectiveness of the retainer.
