Hi Matt, I've used this type with good results. The key seems to be clean, smooth, and dry (no oil) mating surfaces on the head and crankcase. But they all seem to start leaking eventually. http://www.jbugs.com/product/9149&Store_Code=JBUGS.html

I’m close to starting the reassembly of my engine, and I’ve purchased a number of parts to replace things that looked worn to me. One such item was a set of pushrod tubes… however, now that I’m looking at them, I’m wondering if the old ones really need to be replaced. The new ones are the accordion style, the old ones are two concentric tubes with a spring and two o-rings to seal the tube halves together… Anyone have preferences either way? I’ve enclosed a picture of the two for reference.
