Engine oil cooler
i'm having hard time to keep the engine running at the right temp, i'm thinking about an engine oil cooler wich i guess is a good upgrade and should keep a more stable temp, i installed one of them on my Jeep WJ 4.7 and i'm very happy of it is performing.
The only thing i dislike about engine oil cooler is the more load on the dizzy and cam gear (engine is a GM 350 first gen) due to the flow restriction of the cooler and sandwich adapter, honestly i don't know how much this restriction would be but i'm obsessed about cam and dizzy wear, any idea or experience about that?
A thinner oil would help for sure, now i'm running a 5w40 with ZDDP in it, so with the cooler probably a 5w30 is ok but i'm concerned about pressure when warm engine at idle, now is roughly 7 PSI, with a thinner oil will drop even more than that.
I was thinking about another solution using a 12 volt pump that sucks the oil from the oil pan, push that in the cooler and a return line to the pan again, a thermostat in the lines will regulate oil flow so it will go to the cooler when needed or oil is getting to hot and avoid cold oil in the engine during the warm up period, what do you think?
Any opinion will be apprecciated.
