New engine has loss of compression

ok do me 2 favors. you may have done it before...

1. when you first start the engine, the oil dont really do it's job until it gets warm. so there will be 2 minutes or so when it's not working. during that time frame, all your mains/rod journals/cam journals (NOT lobes) should be coated with something. this will get it by until the oil warms: white lithium grease. use a THIN amount on all bearings/journals. you can put a thin layer on the oil pump lobes too. dizzy gear. it's important to only put thin layers because globs can plug holes making the oil to take even longer to reach parts, basically defeating the purpose.
the cam lobes get the manufacturer's lube that comes with. but the rest of the stuff gets lubed with the white stuff. some will disagree and just use the red cam lube on everything but i'm an old timer lol.

2. antiseize. it has a purpose other than preventing seizing. it ensures your torque settings are accurate when torquing all bolts that have a spec. again a THIN layer, all threads have to be clean. for instance rod bolts should not even have a spec of dirt , a small amount of antiseize, it will make sure that your ft/lbs on your torque wrench match what the bolt is actually gettting. use it on all main cap / rod cap / head bolt threads.

also if this is a hot little engine i recommend the valvoline racing flavors or brad penn oils. there are a few other good ones also. rotella isnt really one of them it's a budget/fleet oil. it's ok for normal street operations. anything that is going to really stress the bearings, i wouldnt use it.

i just wish i could be there to hear it run, i love hearing new engines :D
