Hi guys,

if you have been reading about my little project car than you know i got the car going now basically.

Mr. Sanborn said i need to put like 50 miles on the motor before i put her to sleep for the winter up here in vermont.... he said to load the motor but keep the RPM's below 2,000 for the first 50 miles.

So how do you break in a motor?

I have never done this before..

Mr. Sanborn said the MOTOR needs to be under load, not idled.

can you guys give me some advice.

 

Drive it. It would not be good to hold the brake down and keep the engine in gear so I suggest you drive it for a few days. Take it to some lonely roads where you can get the engine to run. City driving is not advisable but highway driving is.

 

i just put a new bb in my burb last year and basicly you just drive it normally,the guy that built the motor told me not to go over 4000rpm.
just take it out for an after noon,injoy it,watch your gauges.
take it trough some hills after you get some miles on it and juice it a bit to seat your rings.

 

Break the cam in as per recommended specifications. Change the oil and filter. Drive it like normal for 500 miles. Change the oil and filter. Drive it like normal after that.

I WILL AGREE.

 

THANK YOU...your web site on selecting a torque converter is real informative.

 

Thats what Ive been told, break in the cam, drive it for 500 miles.
Just dont go doing any redline blasts with it before the first 500 miles

 

What would happen if you DID do some red lining before the 500 mile mark?

 

NEver mind.. I just read that website (mototune's website) and that is an AWESOME article.. thanx for the link dude! I will remember that, as I will have to break-in my 305 this May or so

 

Interesting article...Just read it myself
Has some pretty good logic behind it.
Guess Ill have to try that next time I break in an engine

 

so i got a scanner lined up to check my IAC count and reset my TPS.

i was going to break her in tonight 27 degrees but i had a carpenter in doing my bathroom. so tomarrow is the projected break in day.
