If you're missing the chain tensioner and it was running like that and dying, your valves are toasted. You're past the point of needing a tensioner.

correct! probably will pick it up tomorrow and that will sove the starting up problems!

[KenC]

If it was backfiring that much and stuttering, I'm guessing you'll need to pull your head and check the valves.

Well, im guessing that is something you need to go find :)

[grantlacey11]

well. i figured it out. the missing part is: hydraulic timing chain tensioner. how bad is that!?!?

[KenC]

Either the timing of the cams is off or your spark plug wires are out of order.

So i just replaced my m42, with another m42. got everything bolted in and what not, but there are some wierd things that happen when i turn the key.

it kind of sounds...and feels like the spark plug wires have been mixed up, but there might be a bigger issue.

she fires and starts up, but backfires and fires herself out of rotation quite suddenly and dies. she runs really rough for about a second and then dies.

any ideas?

thanks!!
