I like the Pierburg solution, although I want to weigh one first and look at the power consumption - it may not be as useful as it first seems as these things are done primarliy for warm up emissions and not for crank power, and I run a smaller alternator that may not appreciate the current.
I see you can get unbranded ones from the people who probably make them on ebay, so i'll probably pick one up anyway.
That is for the next engine though.
I got the 2nd prototype chain guide in and tested:
Thats the final guide design and it has been sent to the manufacturers and the delivery clock has started.
These photos are of the oil feed in the left hand balancer shaft bearing housing and the transfer hole to the water pump chain tensioner.
Entry of feed:
Exit of feed to tensioner
This is the bushing i've come up with to ensure the oil goes to the tensioner.
I'm not convinced GM Racing or the US aftermarket and enthusiasts bother, and by all accounts it's not a problem for the tensioner, but I can do it so I will.
And it pops in here.
As simplified cross drilled solid bushing would also work, but I like drilling the centres out of things for weight.
