Did you put the oil pressure plug back in the block?

What head gasket are you using?

 

yeah i put the oil pressure plug back stock a6

 

Did you use a new head gasket?

Did you use the correct head gasket?

How were the mating surfaces?

ya you have to either mill the head slightly to resurface it or check it with a precision straight edge. PURE white smoke is coolant most likely.

does it smell sweet?

 

checked my spark plugs and they have oil on them

 

why is it it was working fine before and started to smoke now??

 

did you tourqe the head bolts down to spec? are they new?

 

Back up a bit...

Correct me if i am wrong:

1. Your engine was fine and you replaced the head.
2. THen you found out the head was bad so
3. You put your old head on it.

Correct?????

If that is the case, answer these questions.

Yes, used the same head gasket

 

Maybe that is it my friend. Reusing head gaskets is not a good idea. I suggest you go out and buy a new head gasket and try it out with the proper torque values and see.

Remember, coat those head bolts with antiseize or oil so they don't bind...

what tourqe values did u do it to?

try a compression test and you'll get some info you can use.

 

thanks ill try and hope it stops smoking like a train
