Worn cam lobes equals metal in the oil and lubricating system
replacing the cam is ok but you will have problems down the track that will require a motor clean out and rebuild unless you clean out all the oil galleys and pump before replacing the cam

I have a 1984 s10 with a 372 small block chevy in it and it runs fine tell you get on it then it backfires through the cub the timeing is good is it the valves or the cam??


Hello, I would check the lobes on the camshaft. Remove the valve covers and start the engine. Watch every rocker arm and make sure they are all going up and down the same distance as each other. A badly worn cam lobe will show as only traveling up and down a little bit .

Shakes and misses while accelerating , has a tick to the engine , i already replaced the spark plugs and wires, 1 new coil pack, air filter, fuel filter , new rear rocker arm and push rod. and oil change


Sounds like you still have a problem where the ticking is coming from. You may have to run a compression test on that cylinder you put the rocker arm on, are that side of the motor that is ticking. Could be the cam lobe wore down and need a camshaft.

After timing belt failure/head swap, how to tell a 94, 1.9L is at TDC? Marks on flywheel at tdc, pump timed with pin tooling, aside from cam lobes #1 both "up", I'm lost. Turn over by hand but valve...


I'd be careful as you know that is a zero clearance engine. Pull #1 spark plug after you get everything lined back up. Make sure it's all the way up and on the compression stroke. With #1 cam lobe up the valve should be closed and seated in the head. #1 piston should not be interfering with the valve lash. Mark the belt, cam gears, and crank clearly. This way when you pull the belt off, you can line the marks back up at any time and you won't lose any ground. What you can do is to pull the plugs and watch the cam lobes. If you have one going down, and a piston coming up...bingo that's your problem cylinder. Here's a tip from an old timer. Make sure the block timing isn't 180 degrees out. After you mark the belt and gears. Remove the belt and spin the crank 180. This will let you move the cam to close the valve on the problem cylinder while doing it. What you're experiencing is a timing issue. Figure out what that is and then line everything back up and you'll be back on the salt flats in no time. I'd be willing to bet that something is 180 degrees out no more tear down involved, just proper alignment.

Cams need to be put back after being removed where do they go?


With the number one piston at top dead center the intake cam lobe on the number one cylinder will face 9 o'clock and the exhaust cam lobe on the number one cylinder will face 3 o'clock.

Hyraulic lifter worn


If it wore down due to lack of lube then there is a very good chance that the cam is worn as well.

Need timing marks for 2002 ford explorer 4.0 engine. trying 2 check timing chain. any one know specs


There are no marks on this one. There is a special tool set to align camshafts ($900). The best you can do is to bring #1 cyl to TDC compression with both cam(valve) covers off. #5 cyl should have lobes at equal opening, exhaust just closing and intake just opening.. #1 cyl cam lobes should each be diametrically opposed to the positions of #5. If cams need to be moved, there is no registration of gear onto cam. Just loosen bolt holding gear and move cam. Retighten bolt. Roll thru 2 crank revolutions and check cam timing again.Simple.

Check engine compression. Those engines have a cylinder arrangement that looks like four drinking glasses sitting inside a cardboard box. During overheat, cylinders drop below deck height and do not seal against gasket. Non-technical repair was to draw file the deck 'till it's even with cylinder tops.
Obviously, check all of your work as well, you may have inadvertently knocked something loose that has to do with starting.
