what kind of smoke? Was it overheating vapors or was it buring oil vapors or what? The loss of power reminds me of when I let my parents' toyota run out of oil, and the loss of power thing added up. However, the pistons were seized in the toyota and you can turn yours over. ???

What did the head gaskets look like?

You've also got some serious build up inside the engine. I would switch to Rotella-T oil.

Maybe it's an optical illusion, but the timing chain looks really "limp". Sure it did not jump time?

[pavel]

The crowns of your pistons are remarkably carbon free and other than some obvious oil leaks, I don't see too much mechanically wrong in your pictures. You said "smoke was pouring out of the hood"....was it black smoke?
As a veteran of several blown engines (rod through block; broken crank; dropped valve etc.) I can tell you that you know about it when there is a catastrophic mechanical failure. This may be a blown gasket or ruptured tube of some kind. Still overheating an aluminum engine is always serious......Happy sleuthing!

sorry i was MIA there for a day or two, school work was a little rough. the smoke was white, i dont know if it was overheating vapors or oil vapors. i dont know enough to tell. and yes i can turn my pistons over.

i will take pics of the head gaskets friday night cause they are at home, nothere at school. once again i dont know what to look for on the gaskets to see if they were blown. they were still in one piece, thats pretty much all i can tell. switching oil is fine with me as soon as it gets running again.

the timing chain was a little limp. there was some give to it but i dont know if it was enough to let it jump, could have jumped. is my engine a non-interference?

there was one tube that looked like it had a cut in it


that better not be the majority of the problem and the dealership didnt know, but then again if it is then i know whats wrong, im planning on replacing all the hoses

also these




any other part you want to see a picture of, i most likely have it caues i took 180 pics total. how bout this one? thats what we make



thanks guys, keep it comin

Ok, well first of all, I think what happened was you blew a head gasket! The top of the pistons, as mentioned before, are remarkably clean! That is extremely abnormal, especialy in a rover!!!! It appears as though they have been steam cleaned. We need more pictures, especially of the other side of the engine, and of the underside of the heads! I would check everything. Bring the heads in, and check the tolerances! You could also have a warped block too! While you are there, break the whole engine down, clean the pistons, put new rings in, change the bearings, install a new timing chain, get the heads redone with the new valves, and put the truck back together! Its just all work now, providing the block is ok, of course! Oh, that coil pack looks burned in a few places! I would get another, or have it tested!

Second the pictures showing broken vacuum lines were of your cruise control, no worries there, get new lines, and you will have your cruise back!

Keep us updated!!!!!!!
Best of luck!

Well, that explains why your cruise control does not work....

White smoke is not oil, it's coolant. Blue smoke would be oil.

Still, it could be any number of things. Slipped or cracked liner, cracked head, blown head gasket, etc.....

You should have done a compression test on the motor before tearing it apart.

When you tore down the engine, did any cylinder have antifreeze in it?
Did your oil have coolant in it?
Was the overflow boiling water?

I'll just throw out a theory going by the information you've posted. Again, this is just a theory as there is not enough information to make an accurate diagnosis.

I say either a head or liner cracked. When it cracked, it allowed the engine to over heat. In addition, exhaust was being blown into the coolant system causing antifreeze to blow out of the expansion tank and cause the smoke under the hood. Depending on how long you ran the motor would determine if it's worth fixing.

1) I would have the heads tested. If they are ok, go ahead and get a valve job, flat mill, and new seals. If you want to make some more power, have them ported.

2) I would call D&D and get a used block. Also take the block to a machine shop to have it cleaned, honed, and new bearings installed.

3) Install a new cam. Something like a 258 or 260.

4) New timing set.

After you get everything back in the truck, you'll be golden. With extra power to boot!. You'll end up dropping about 1800 - 2000.00, but it's a better option than buying a junk yard motor.

Well said!

i checked the compression myself and found 100, 70, 60, 80, 90, 50, 60, 60 compression in the cylinders starting from the front one on the passenger side and going back and then the front one on the drivers side and going back. i dont think i performed the test properly, but i believe if i did do it worng, then my results should be, if anything, lower than the actual compressions.

i cleaned the coil pack and tested each contact for spark, some spark stronger than others but all spark.

i was wondering why the cruise control didnt work.

ill get some pics of the heads and the head gaskets friday night. and i guess ill just look for some general photos of the other side of the engine when i get back to my room. im in the shop right now, so ill get those of the other side as soon as i can.

That explains why the motor does not run

[Disco 1]

yep i know that, but what i dont know is exactly why i got those low numbers

Did your oil look milky?

Only think I can figure is a liner let go, water entered your oil, and then you cooked your piston rings.

[Disco 1]

my dad said he didnt think the oil in the oil pan looked like and coolant had mixed in with it

best pics of oil i have

[pickuprover]

What are the metallic looking deposits on the last and 3rd last pictures of the pistons.. are they metal, or just dirt that has gotten in them from the tear down.... also they look oily?.... did you blow a couple of rings?
