1974 Blazer Engine Removal

Yes, i like to take the cap off and mark where the tip is pointing on the manifold and on the base of the dizzy so its all lined up, Also why I put mine in when I installed it because its a pain putting it in while the engine is installed, especially if its a few teeth off or something.

WHatever you go with just dont roll the motor over while its out so everything is set the same when you put it all back together.

Turn the engine to #1, check that the rotor is pointing to the number one plug wire on the cap. Use your trusty felt marker to mark where the rotor should be pointing on the body of the distributor. Remove the hold down and pull it straight out.

Not having a tranny attached you could get away with just pulling the cap with wires attached, and the rotor and be just fine.

does mine have a rotor if it is an HEI?
 
Yup, sure does. If you remove the distributor cap you'll see it underneath. Phillips screwdriver gets the cap off, don't forget to unplug the electrical wires going into the cap (for the coil). Once the cap is off use the same Phillips screw driver to remove the rotor. The cap and rotor both can only go on correctly one way, so no need to mark anything, or turn the engine or anything.
 
While I got the engine out I want to do an exploratory look around in there....not too detailed but I want to do a reseal or gasket kit on it.

I am told that if I use diesel or something like that to pour in the heads and let it drip out the bottom that I would need to prime the oil pump when I have it back together....what's the best way to prime the oil pump?

Also, on the back of the engine where the cam shaft is there is a cover that looks a lot like a large freeze plug....what is that called? I think that's where I have an oil leak...
 
To prime the motor, take a longish big flat head screwdriver, cut it off at the handle and put it in a drill. Turn it clockwise i beleive. Thats how i did mine, did it till it was coming out of the lifters. Before priming try to remeber the way the slot in the oil pump rod is so when you put the dizzy in the rotor points in the same direction.
 
And is diesel a good cleanser to pour through an engine or is there something better?
 
OK...I found out that thing is called the camshaft plug....it basically is a large freeze plug...anybody ever seen one of those leak oil?
 
Seen it? No. But that's because it's hidden. Seriously though, it's common enough. I've never had to replace one myself. Scott (4x4high) would be the one to PM about that.

Not sure if I would bother trying to clean the inside of the engine unless it was all sludged up. If you pull the valve covers and intake you can get a good visual on the inside condition of the engine. Take pics, post em up. If it's all clear, new gaskets and reinstall parts. If it's crusty, take it from there.

So, I'm thinking you are gonna clean and paint the engine while it's out. May as well, it'll look great.

As far as internal engine cleaning goes, ATF has excellent cleaning properties. Plus if some is left in there it will mix with the oil rather than diluting it like diesel would.
 
Hows the motor seem to run at the moment? How mny miles are on it? Sorry i could prolly find it but im on my phone dont feel like searching lol. Depending on how it runs you could either just do gaskets if its runnin good, or on the other hand dig a little deeper into parts... (Clean up the heads while they are out, cam, timing chain etc....) just a thought, im sure its been said already.

I kind of feel like "if it isn't broke don't try to fix it"....but...the back of the mind wants to know what condition it's in...
 
I would pull the valve covers and have a look. This is also a good time to do a timing chain, and reseal the front cover/water pump. It also might be a good idea to pull the pan, and replace the oil pump, check the wear on the bearings. This will give you a better idea on the miles on it.
