Percolation? Heat soak? Don't drive during summer??

If I'm not mistaken @70aarcuda buys whatever flavor Walmart oil he can find in the viscosity he wants and ads a 4-ounce vial of zddp.... Myself I'm more of the school of the manufacture didn't go through all that testing to make the perfect formula and then I go ahead and try and think I'm going to outsmart them and make my own formula LOL... There's got to be at least 10 other oils out there that also have zddp in them.. but I'm sure the one that you use is more easily gotten at the local parts store... With all that said I would be much more much More much More looking at your fan... and that's the reason I really want to know what temperature your cars at when you're going down the freeway for 20 minutes at a steady speed. If it's all good and dandy at speed for a long while that's going to be the catalyst for a circulation problem of air when you're not going at speed..

Yes he does run what ever Walmart flavor he likes at the time. Same with transmission fluid too I think.

I think when I first got the car and did a tune up on it (wires, plugs, oil change,coolant flush with new cooling parts minus radiator) i read here that the vr1 was good and already had a high zinc content in it. I went with that because it eliminated the potential of me adding to much zinc or to little zinc to an oil that didn't have any or the right amount in it. Many of you guys have been doing this for many years so to you most of this is second nature and you've come across many of the common and not so common problems. This is my first old car, and first time I've really really torn into a car to rebuild different systems so I'm trying to not make the dumb mistakes... like not adding extra zinc to the wrong oil. Ill just remember to next time I change the oil, to add a lower viscosity oil, which may be sooner rather than later because my oil drain plug leaks and I want one of those fancy deep oil pans. Tony actually showed me the one he likes and offered me one when we did the cam but I always like to not take things from people and felt that I could buy later on. :)
