new crankshaft installation in a 4.6 4v svt.

is it possible to install a new crankshaft without removing the cylinder heads i spun number 7 rod bearing and believe i have found all the bearing material. the motor only has 6ok on it and ran like a clock with only a slight rap at 1800-2000 rpm and i hate to fix something that isn't broke.

Yes, you can change the crankshaft without taking the heads off...for me, though, I would want to double check everything. With the engine out, I would want to replace all gaskets with new ones since the engine out anyway...

Take the coils/plugs off so when you go to spin the crankshaft, you aren't fighting compression.


Good luck!

Is the motor in or out of the car?

the motor is out and on a stand with the pan off and the bad bearing in hand,i have the new forged crank and bearings and cam tool kit, but it looks like i need 2 holding tools and the kit only comes with one is there some thing i don't know. I also have a main cap bearing bolt kit but i can't find rod bolts for the stock cracked rods.
If i have to i will pull the heads and upgrade the rods and pistons but everything looks new up there and i don't like changing head gaskets on aluminum blocks if i don't have to. please share.
thankyou; brians99
