If the valves are out of time they hit and it will take a good deal of force to turn the engine and bent the for the next 2 revolutions until they are all bent. Once the valves are bent, it will rotate pretty freely because nothing it really hitting anymore and there is no more annoying compression trying to stop it from turning

I think they SHOULD be retorqued and the lash needs to be checked (if the heads have been worked on) so I'd think you'd retorque during the lash check. How a shop bills for this is up to them. Certaianly they can include it in the original estimate and that is probably the most honest way. The next best it tell them about it and give the cost estimate before starting the head work. The worst option in take the job and as the car is leaving "oh and you'll need to bring it in at 500 miles for a head re-torquore, thats another $500 Ididn't tell you about". Its sounds like your buddy just needs a mechanic he trusts..once trust is lost everything becomes a question and that's probably not good for anyone. But that's just my opinion. |

Getting dirty digging in old threads here... Head re-torquing is an interesting thing. I personally feels that it's only done when the assembly wasn't done as intended. I'm not saying wrong per-say but it comes down to the block and cylinder design as well as the materials in question. In this case with the 308's and forward the block and heads are the same material, the cylinders are 'floating' and use an 'O' ring. Now my stance is that if the heads have been pulled then the liners should come out as well and the 'O' rings get replaced, yes it's a bunch more work and a PITA but the engine was designed to have the liners sit proud and get 'set' into place, the head gasket and 'O' ring provide the correct amount of 'crush' so that re-torquing should not be needed. If the liners have not been pulled then re-torquing is more then likely going to need to occur. The other fly in the ointment right now is head gaskets... whats available is crap, after loosing an engine to cometic gaskets and the change in elring construction I went and sourced a mfg that makes us 3D profiled head gaskets that crush as originally intended by Ferrari and also have a silicone coating. ZERO issues now. These are just the thoughts of a simple engineer... |
