Now you two go bug Bob K for saying this, that even I wouldn't do. Newer engines need thin oil. Bob K "we use it in our street cars as well, even these new fangled things that only want 5w-30 or what have you."
Hmmm diagnosis...its wore out, no-one changes thier oil religiously on an old car to sell it to someone else. Technology is a wonderful thing, hell, even Buick went to oil via lifters and pushrods since his motor was built. As for stabbing new gears and a wear plate in, hell, thats just PM for a 40 year old motor. Now, if he was going all high speed low drag, he could score a cover "off'n one dem dere new fangled v-6's, got dat dere vane type oilin' pump like in an automatic transmission...." But, that is a whole 'nother thread. :3gears: Oh, and last I checked, the only oil not synthetic is single weight racing oil. All multi-weight oils are at least semi-synthetic. The only reason I advised changing weights and filters makes, is on some vehicle it makes a big difference. Notice that the oil cooler small block chevies got anti-drain back valves in the filter now...AC-1218...? Glad the beast is all tuned up and not tickin'. That was fun. Can we land an airplane next time? :Comp:
What Just because an engine is 40 years old doesn't mean its worn out. Are you a ghost? :laugh: Identify yourself and what you drive.
must be a mopar guy...haha i do appreciate what you have all said though. it never hurts to have a little "discussion" about what we are all thinking. now if we really wanted an all out war id start in with my greaser rhetoric haha
<!-- / icon and title --> <!-- message --> Now you two go bug Bob K for saying this, that even I wouldn't do. Newer engines need thin oil. ummm, there's not really a whole lot to debate me about there? you never used to see manufacturers recommendations for less than 10w-30. these newer engines ( EFI, tighter machining tolerance engines ) that have been coming out since the 90's have manufacturer rec's for 5w-30 or lighter. it's in the owners manual. especially if you get a jap car. Time to read up on friction. If you can do the job with thinner oil,you'll get more power to the ground. But then that might make younervous! Heaven forbid. errr, yeah. will you make a couple of more HP with a lighter oil? sure. shouldyou be concerned about it in anything less than a full on racing, everythousandths of a second counts application? me no think so. anybody and EVERYbody who is "concerned about friction" willset up their ignition and starter on separate circuits ( starter wiredto a momentary push button switch on the left side of the steeringwheel will work fine for this ) so they can build oil pressure on thestarter motor before firing the engine off. no, i don't do that for any of my street cars. Also I am a little scared of the 20w being nasty to the distributor gears on cold startups. well i wouldn't use 20w during the winter, no. I think Devon knows what he's talking about, you have no argument besides your feel or peace of mind. decades of experience and personally putting over 200,000 miles on motors that had 80,000 on them when i got the vehicle counts for nothing? otay. :spank: im gonna rebuild the oil pump just for safety sakes. id rather be safe then sorry never a bad idea.
Geez, after all the "spirited debating", can anybody give me a good reason to run 20W-50 in my Wildcat, when I can get 75 psi @ 6500 rpm on Mobil 1 10W-30? Going up in viscosity has its place when an engine's bearing clearances have been set for a certain job. 7500 rpm and 13:1 compression needs loosening and more oil volume. If an engine is just plain worn out or poorly put together, that's another story. Devon
Geez, after all the "spirited debating", can anybody give me a goodreason to run 20W-50 in my Wildcat, when I can get 75 psi @ 6500 rpm onMobil 1 10W-30? yours sounds fine to me. but then the last i checked, this thread wasn't about giving you advice on your particular engine. :spank: :laugh: If an engine is just plain worn out or poorly put together, that's another story. and a 35 year old engine with probably 80,000 plus miles on it is likely to be what?
Bought the booster plate kit and am reading instructions ...............drill an extra 1/4" hole in plate. Will this effect oil pressure?
