Loud Clanking and rough idle

[KelseyM]

I will check it out when I get home...

Is it possible the timing chain could have slipped?

It's a rover...anything is possible!

[KelseyM]

Haha, very true.

I started the rover up just now, after getting the truck slightly warm so it would stay running(rough) I started pulling plugs to see if the idling would make a difference. Cylinder 1 and 2 did not seem to make any difference when I pulled them.

I am going to pull apart the distributor to see if it is the weights, is there any way to tell if they are unbalanced?

Not sure about the unbalanced part. Mine were 'frozen' in place. I took them out, sprayed them with 'breakfree' made sure I wiped them off and then put them back. No more dieseling under load.

Oh ok, I miss read your previous post. Ok I am going to pull them now and let you guys know how I make out...

I checked my fluid, does not look like a head gasket oil and coolant are clean.

That doesn't rule out the head gasket--it could be burned out between your #1 and #2 cylinders (see the non-Rover example below). I'd just do a compression test.

Mark what do you know about head gaskets?

Touche.

Could be, I just took apart the distributor, and reassembled it. Everything looked to be in order, and afterwards the truck started right up and idled much better than previously. However I could still remove both spark plug wires and it idled the same.

I dont have a compression tester, I will have to pick one up tomorrow

But does it still knock under a load?
