What weight oil for the boosted guys.??
#42
Ok, I changed the cam retainer plate, stepped up to the 15w40 oil and while the front cover was off I changed the oil pick up tube o-ring "again". I was anxious to start the car and see no more oil issues. Well, I started it up, cold idle was right at 6 lbs. As it warmed up the hot idle was right at 25. Much better then the 10 lbs before... But the issue Im having now is not while driving. The oil pressure while driving is fine, my issue is when I come to a stop. The oil pressure briefly drops off to about 15 lbs. Then I glanced up and noticed that the RPMs were briefly dropping off to about 300 RPMs. That made me wonder If I ever really had an oil pressure issue. I know that the oil pressure and RPMs work hand in hand, when the motor RPMs fall off the oil pressure drops off. Now I need to find out why when I come to a stop my RPMs briefly drop off. Its a new 6 liter iron block motor, so there are more cubes. I just cleaned my IAC motor, to see if that would help. I wonder if that tiny little hole in the throttle body blade has anything to do with it. Does it need to be bigger, now that I have more cubes...

Well if your idle is down to 300 rpms, your oil pressure is going to be low. All the throttle body blades have holes in them. That is a tune issue as far as the idle goes. Get that fixed and you should be good then.
As far as the 15w40 rotella oil goes, how many miles did everyones engine have on it before they started using it? I bought some for my engine to use for the startup after the turbo addition is finally finished. Kinda worried, don't know why though. Just looking for some reassurance I guess.

Yesterday on Hot Rod they were talking about oils, They stated that the shell Rotella was good for break in only and if you kept using it that it would cause something, sludge build up? I dont remember. Might want to see if you can catch this episode, Rolling Rock in one hand and a rib in the other causes a slight impediment.

When I first put my setup together, I ran Advanced Auto 10-40 for about a week. It was intended to just flush out the previously used motor. I had no issues. I switched to Mobil 1 0-30 and now as soon as I get up to operating temp (about 210), the turbo smokes like crazy when i come to a stop. I am going back to a heavier oil.

Well, I finally got the idea to have the tune check and appearantly the idle from the previous tune was off. Everytime Id go to slow down the oil pressure was dropping off. Well, I didnt notice the rpms dropping to around 300. So, of course the oil pressure would fall. Im using Rotella now and so far so good. Thanks for all of your help guys. Man, little issues can end up turning into real headaches... CHEERS

I'm not sure that I know Josh. Perhaps a little more detail. Like city, color of car, something.
