Why does my car smoke out the valve covers real bad when I give it gas and mildly when I idle? Is there something in there that needs to burn off? it just started this morning, I noticed it smoking and so I disconnected the PCV valve from the air cleaner caiuse it was pretty oily up there, but it still smokes...

Scott,your PCV valve needs to be plugged into a manifold vacuum port on the manifold itself or to a port on the carb.the breather can be run to the air cleaner if that the type you have on.If everything is hooked up right then you have a blowby problem.

Can't sugar coat this one, nor will I tell you what you want to hear. Catman's 100% right.

If you ever road in a a small block car that rips, you would throw stones at all those big heavy rats, except the 427 of course, the small block of the rats.

But, since it cost many dollars to build a killer SB, do the rat thing, it is cheaper, not better just cheaper.

Wally, I'm beginning to think you're cyclothalimc. Rats are good, mice are good, which is it?????

Scott, they're both OK, but if you never done this before I think you want to stick to a simple replacement job and not stuff a rat in. If you end up liking getting your hands dirty and enjoying the satisfaction that you can tell all your lily white friends that " I, yes I, swappped the motor" and be damn proud of it, you might be a candiate for ratitifaction. ( Sorry many of my acquaintences are "yupsters" so I kind of "scare" them, when I tell them I put the motor in myself and may pull it because it doesn't do the 550 HP I want - they run from grease.) But, I'd keep it simple. Check the good engine shops in the area. A client of mine has a stock 350 HP 350 for sale for $1100, basically what he has into it, because the customer reniged. Man, if I needed a mouse, that's a steal. A bit more cam, Z/28 type manifold and SHAZZAM no more blowby!( which incidentally is that the gases from compression are not only going out your exhaust, but sqeezing past your piston rings and filling the crankcase. You should be able to feel the "puff, puff puff" if you put your hand over a non-baffled breather ).

So start scrounging around, both for a helper becuase it's way easier with 2, and a new mill. To wheel the Chevelle for cheap becuase it has a worn motor is foolish. If you decide to go that route, let your TC buds have first dibs on it. That was exactly what I was looking for 9 months ago, a car with a bad motor that someone didn;t have the time, money, or interest to fix. I had a 427 just waiting for a new home!!

So start shopping around. Fellas here say they get rebuilds from the shops at around $1500 or so. Let us know if we can help. There's a bunch of Texans 'round here, maybe they can steer you to the right engine shop.

Scott, it's not a problem, it's an opportunity!

If this will be your first engine rebuild, stay with the engine that you have. You'll not only have to switch the engine, but all the accessory brackets and the front springs as well, if you go to the big block. This can be a source of extreme frustration to a novice. It can be difficult enough just to try and reinstall OEM pieces in their original locations. When you tear something apart and start from scratch, that's how a lot of these projects end up as basket cases. Try to keep the first rebuild simple. When you gain more confidence and experience, then go for upgrades, like power snorting rat motor

Those are pretty good suggestions Gene and Randy.. I think I'm going to stick with the small block.. READ MY POST UNDER "Ever get discourgaed" and you'll understand how sick I am of this car (correction: problems with thi car) But I just bought a daily driver yesterday (76 Pontiac Grand Prix SJ - 400, auto 88K Original miles - 500bucks!) Mint condition.. I'm not joking.. The Only problems with this car are the plastics degrading, and alignment is a little off. One of the blinker lenses is broke.. It's a luxury car, I'm not kidding.. 185 horse bugs me though..
Anyway... I have the time now to stop fixing it every weekend, and save and do it all right. I'm wanting a brand new small block that I can put heads, cam, 400 crank, etc.. I can redo the suspension, clean out the interior, etc..

So I think I'm gonna sit tight and do it right..

Scott when I was 16 I started a hevy duty gearhead phase and had the same prob - always underneath my daily driver. My mom kept saying " What tdoes that car look like with the hood down?" - 'cause it was always up. Anyway I bought a 66 Biscayne 396 T400 beater and my stress level dropped dramtically. ( Until I dropped a valve in the 396 and a few weeks later blew the spider gears by revving on ice and then hitting dry pavement - AARGH).

Don;t beat on the GP. Have it aligned and drive it easy!

Happy holidays Scott!

Take care of that GP. I had the same car & loved it more than any car I've ever owned (besides the chevelle). Forget about the lack of horsepower & just baby her. You really will appreciate how well she cruises. Take your time on the rebuild & it really is rewarding that you did it yourself.

Oh, I will. I'm not touching this car, except for wheels, and the stereo.. I love it, and I'm going to have to say it's the smoothest riding/driving/turning/stopping older car I've ever had the pleasure to ride or drive in.. 8)

Oops, had to edit my last reply. The first sentence should have read, "If this is your FIRST rebuild....." I think you understood what I was trying to say, though.
