Anyone switched up to one of these springs in your oil pump? Did u notice any difference? Can it be switched out during my next oil change? Any experience from fellow Ponchos is welcomed! Thanks Greg

Is Eastwood the only company that sells black radiator paint? I don't want to spray my nice new aluminum rad with regular paint because I've been told that's a great way to reduce it's efficiency. Anyone seen any other place to buy specific radiator paint?

I have been chasing multiple check engine codes with a trip to the dealer each time. It now seems that the code last read indicates replacing the catalytic converter at a cost of 1600 to 2000. I have run one can of seafoam through the gas and am now on my second Seafoam tank. Is the Seafoam going to clea...

Today after a brief burst up to redline through the gears in the 67, when I slowed back down, about a minute or two later while cruising a tick appeared and became pretty loud. Enough to be concerned, but not bad enough to stop. You could hear that it sounded a little different through the exhaust as well....

Maybe this question has been asked before and i remember hearing that vintage motors will leak because of old sealing technology. If it is safe to use in vintage motors, i was thinking of using it in my 57 Pontiac 261 inline six and my 74 Chev 400 V-8. I am thinking that maybe the only real concern is the pos...

Had the car out last week for a quick jaunt and all was going well. Headed home and something didnt seem just quite right.
