    i recently have pulled my old motor out and put in a used motor with 65 k miles on the stock bottom end and did a complete HCI swap with lifters, cam shaft , rr's push rods, etc.. when should i change the motor oil and should i put in another comp cam break in oil i have ? when i put the oil in few months ago i added the comp cam break in oil and was wondering if i need to put in another one or not ? also what oil does everyone prefer.. thank you

    Is this a roller cam/setup or solid? I suggest running around 100 miles on break in oil if break in lube is used and then change it.

    I don't think you have to break in roller cams, I know I didn't with mine. Just synthetic oil and go.

    Exactly where I was going with that. Its not necessary. Dont see how it could hurt anything, but certainly not necessary.

    If it's a new cam then I'd suggest flushing the oil after 50-100 miles and putting 2 good magnetic drain plugs.

    Sometimes new parts including camshafts aren't 100% burr free. Why risk shortening the life of the engine over a $30-$40 oil change.

    i should have said a lil more info ... sorry,... its a 95 gt with a stock bottom end w a hci swap.. i did put it a bottle of comp cam break in oil in the beginning but i did not i did not put it royal purple oil in it knowing i was gonna change out soon... so even though i have brand new cam shaft, lifters, roller rockers, push rods, cylinder heads, i should not put in another bottle of the break in oil with my next oil change ? i do have the bottle already so its not gonna cost anything i just don't wanna do any harm to it if too much is no good and figured if it wont hurt the engine to put it in while i have it n if i don't use it now i prob wont end up using it.. whats the average miles you should change your first oil change when doing a fresh swap and all new compenents ? thanks again

    I dont find any need to add the additional break in lube on the oil change. I would swap out around 100 miles as previously stated to the oil and filter you plan on running for the remainder of the life of the engine.

    normal break in procedure is usually of course you have your zinc lubrication on your lifters and camshaft , if you built the engine I always use STP honey on my pistons and cylinder walls as well. Some people claim you shouldnt break in with synthetic but I have not heard of any of them going wrong and I also broke in with castrol gtx full synthetic . I believe you bring the car to around 1500-2000 rpm and hold it there for around 30 minutes to break in . Hope this helps you my friend some one correct me please if im wrong but I believe this to be correct.

    Yes there is break in oil.. most of the break in process is to seat the rings. Your over thinking it..

    When I broke in my engine I ran out for 5 min flushed it out in fresh oil. Changed it 500 miles later. then again at 1500. Then normal after that.. using regular cheap oil..

    my advice is use the STP engine honey when building your next engine and use some zinc on the cam and lifters and then just run some good castrol synthetic oil. you will be okay.
