258 with 140k and knock. Oil weight question. Timatoe this ones for you lol
Ok so as I said I have a 258 with 140k miles on it and a knock. I've heard that my knock is a collapsed lifter, piston slap, timing chain, valve tick and so on. Can't track the knock down but I've got good compression and good oil pressure as well so I'm not too worried. I've been running 15w40 Delo in this thing for about 1000 miles and it is black so I'm gonna do an oil change. I was curious if I would be fine switching over to 20w40 or 20w50 to help quiet her down a bit and get her lubed pretty good? Also the temps here at the moment are consistently between 60-70F at 6am and 90-105F by noon. In the winter the temps can get below 20F so I would obviously be switching over to 10w30 in the winter. Thanks again y'all for your help.
Timatoe or Mr. B live near here so what's your input fellas?
