anyone recomend descent leakdown tester?

but i will put my pcv on the drivers front, and the breather on the passenger front and i will put the oil cap on the passenger rear and see what happens, like i said when i put the clear fuel filter in my pcv hose it did help with the smoking, the smoking wasnt as much, but it was still there, possibly because there was too much pressure in the crank case because i didnt have a brether. And hopefully my plug fouling issue was because of running my vaccum advance off of manifold vaccum, requiring a richer idle air mixture at idle, i had to richen up the idle air mixture screws quite a bit when i ran my vaccum advance off of manifold vaccum. I had never heard of running the vaccum advance off of manifold vaccum, untill i purchased a distributer from don at fbo systems and he insisted the vaccum advance be ran off of manifold vaccum. I do notice a cooler idle with vaccum advance on manifold vaccum, and i also noticed slightly better throttle response, but other then that it just caused me problems because i had to fatten up the idle mixture so much to keep the enggine from popping out the exhaust with the extra timing. I think 16 degrees initial timing should be plenty for this 360, it doesnt have that big of a camshaft in it, hell 14 degrees initial and 32 degrees may be ideal for it, i just figure i might turn it up to 16 from 14 since i will be lossing 10 degrees of timing at idle since removing the vaccum advance from manifold vaccum.
