My childhood friend's father was a shade tree mechanic and a good one. When he built a motor he would break in the cam per the manufacture instructions. drain the water and run it for a couple minutes to get the block hot and seat the rings. Let the engine cool down add coolant (the block could crack if you cool it down fast). then "test drive" it. burn outs, 10 mile high speed run, doughnuts, basicly burn 5 gallons of gas as fast as possible. His motors last for a very long time. the 454 had 300K on it when his wife took it in the divorce. I feel sorry for whoever bought cause he poured 3 pounds of sugar in the oil

I think the real secret is frequent oil changes in the beginning. On motors from scratch I break in the cam, change oil, 100-500 miles, change oil, 1000-1500, change oil,3000 mi change oil, then every 3K after than. On a new on def change around 1500. then 3000 after that.

What's your thoughts on an oil cooler. I'll be doing mostly DD with a few spirited drives. I might not get the oil temp that high?
It seems to be a very common topic, but alot of guys have stilled them.

RE: an oil cooler. You will know if you need one. Going uphill spiritedly, in one mile I went from 220-245 and in another mile to 260*. This is my daily drive home too. I got an oil cooler and oil temp is just like water temp now, constant.

I really dont feel the break in procedure. I have noticed my Z with only 3,000 miles is a half quart low. I changed the oil at 1,500 miles so maybe I didnt put enough in. Ill double check next time it comes around. Anyways I have a 06 chevrolet truck with 110,000 miles on it. I bought it new and have always changed the oil every 4,000 miles, starting at 4,000 miles. The truck has never burnt a drop of oil and I use castrol 10w 30 standard not synthetic. Maybe I should use this in my Z too.
