help me :( Replaced intake gaskets today cause i went through 8 quarts of oil in 3,000 miles. I didnt see any smoke or anything but thought i would change them just incase. car runs at 400 RPm shaking spuddering I give it gas and it backfires. PLugs are BLACK and exhaust smells rich. NO smoke is coming out Timing is at 8* double checked it. Also seems number 2 and 7 header pipes are only warm. wires are double checked. all vac lines are good. sprayed carb cleaner everwhere. I'll fire right up as soon as i turn the key. 1 sec later its ready to stall. also the car doesnt sound right (exhaust note wise)soudsn like ever wire is all messed up

Sounds like your distributor is 180 degrees off. Maybe your #1 cylinder was on the exhaust stroke instead of the compression stroke, when you dropped the distributor in.

Could be the distributor, but I wouldn't think it would start at all in the case of 180 degrees off. It's more likely you missed a tooth or two if it's related to the distributor.

Did you try using an inductive timing light on each plug wire to look for "bad" cylinders? I've found many bad wires / caps / plugs that way.

Is the car carb, TBI, TPI???

I'm a bit confused as to why the intake gaskets would have anything to do with oil consumption... I'm not aware of any vehicle that has oil flow through the intake... coolant, yes, but not oil. I can think of four main ways to lose oil:
1) bad rings
2) bad valve stem seals (blow-by)
3) cracked block
4) external leak (oil pan, valve cover, filter, etc.)

His car is the 350 TPI BTW.

If the car is TPI and it's running rich, you may want to check for proper fuel pressure. If the regulator is gone, the pressure may be too high and the injectors could be dumping fuel.

The other possibility is the MAP sensor or some other vaccuum gauge problem. If the car begins to stumble when the computer enters "closed-loop" mode (after its warm), it could be due to a faulty sensor reading that the computer is getting. I've seen the computer command a rich mixture when the MAP sensor did not have a vaccuum line hooked up (or it was broken and leaking).

Hope this helps...

Also check and double check the wires for being in the right firing order. You may have a couple of wires crossed and still not get a backfire. So I would say ck them out. Always start with the easy shit first.

Maybe you dropped a spark plug and closed the gap?

i forgot to tell you i took all my rocker studs out and put teflon tape on them and then screwed it back intot he head. (that was the problem) car is fixed and runs beautiful the problem was the number 2 rocker arm i put on backwards meaning the nut seat went down first then i cranked it down tothe set screw meaning the intake valve for # 2 was alwasy open. and on number #1 like jz said i dropped it and the gap was shut solid. i have now driven 300 miles and the oil is at the FULL line spark plugs look BRAND NEW and my vacume is now at 14hg instead of the 11hg before. i still get massive knock on downshift though. something like 31 degrees retard.
