Just finished installing cold air intake. Generic variety nothing fancy. Now taking it all apart for cam, lifters,springs,guides,oil pump, probably timing chain, knock sensors. Going in deep, I’m in there might as well. One question is it hard or necessary to replace cam bearings with new cam? No problems now. I will probably mic it for out of round. One thing leads to another. My brother calls it the “ but first” syndrome. Wish me luck.
I don't think it's necessary, but if you can do it, I would. Wouldn't the block need to come out to do it right? My last motor's cam bearings went. I wound up replacing that motor.
Welcome I’m not a troll but I look like one so there’s that. Watch out for @adventurenali92 , meanest guy on the forum.
Down boys,down. I would like to keep block in and just remove heads to upgrade. If I removed block, I would probably do the whole enchilada.( But first, syndrome ) Doing the injectors, fuel rails, coil packs today. Moving slow, first time, pics notes labeling etc. the wire harness looks like it’s a bear to move out of the way. Deal with that when I get to it. Lots of plastic parts that like to snap off. Geez. Here’s a pic. I should rename photos to eliminate the long text.
Replacing the cam bearings would be dependent upon their condition once you have the old cam out and can inspect them. Chances are, if it's fine now, it'll be fine with just sliding in the new cam. Replacing the cam bearings requires removal of the block and rotating assembly. At that point, you may as well do a full-on rebuild with machine work, etc.
The wire harness is easy. Unplug all the injectors (these are actually the biggest PITA of this part due to the connector locks), all the sensors, etc. and flip the harness over to the driver side. There is a leg of the harness that goes around the back of the manifold to the passenger side. I just hold this up while I pull the manifold out. Once you finish with whatever you're doing, hold that harness up out of the way while you slip the manifold back in place then lay the harness back over the manifold and all the plugs will fall back near their respective connections.
Finished fuel rails, injectors and coil packs are off. Could have removed the intake but waiting till I get the nuts off the exhaust. Pb’ed ,let em soak. Tomorrow prob get back at it to remove exhaust, intake, timing cover, etc. The wire harness seems to go down the back of block. But I think I can get it out of the way. Then the heads come off. Thanks guys for info and tips. Appreciate it.
