Gosh darn head gaskets

It looks like the head gaskets on the 4.2 are leaking again. It's been less than a year and under 4000 miles. When the engine is cold it's pushing a little bit of coolant thru the exhaust. After warm up it seems OK.
I don't know what to do next. I used the very expensive stretch bolts and composite head gaskets which I figured would be the last of it for a long while.
I don't know if I should try going another half turn on all of them, pull the whole shiz apart again and put in the same stuff all new, or go back to the steel gaskets and regular bolts. I know the heads are straight and the block is true.
I don't drive it all that much, but I would like it to be a bit more reliable.


OK stop laughing.

Do not worry at all, V8 are a breeze to work on

You can re-torque head bolts in 10 mns on a Tdi

Thanks for that Julien. I have been into this engine quite a few times.

I have had 2 different 3.9's in mine and had the heads done probably a total of 5 times. They are not my friend.

Are you sure you don't have a slipped sleeve? In the end, both blocks I had slipped a cylinder liner. When that happened in the second block I said some unpleasant words and then converted to a 300TDI (which then blew a head gasket because the jackhole I bought it from didn't torque two of the head bolts when he put new heads on it).

I should probably just convert it to electric.
