[Spridgets] Rear main seal

[Rick Fisk]

That's what the factory PCV systems does.  The last version used from about '70 to '74 works the best *without a PCV valve*.  It connects the oil separator canister on the timing chain cover to special ports on the SU's without a PCV valve and works very well as long as the engine is in good condition.

I ran one of his kits on one of my race engines and it worked well.  But Gerard quit making them a few years ago.  He came out of retirement a few weeks ago and said he was going to produce another batch, but I believe it's too late to get in on this run.  The other kit for sale out there and sold by Moss, Spridgetmania, etc. all come from the same supplier in England.  They slow the leak down, but don't really stop it.  I have one of those on another engine.
