Quote: I just can't wrap my head around a "mechanic" setting valve lash on a slant 6 with the engine off. I suppose you COULD, but the (best) way to get the most accurate adjustment is with the engine at hot idle.
How to best set the valve lash on a SL6 has been argued a lot. Besides, if it's not running during the lash adjustment, you don't get the "satisfaction" of hearing the clattering disappear as you go down the line. I've had times where the valve lash has been off enough that the engine won't stay running and a cold lash is needed just to get it to at least run rough. not that its proper way to adjust the lash, a cold lash adjustment just has its time and place. |

Did you re-check the valve lash after tightening the head bolt?Better yet... Warm engine, retorque the head & re-adjust the valve lash... to the loose side of the settings. DD Thanks! I just spoke with my mechanic and we had come to a similar conclusion that you're saying. I just found out that his order of events was that he tightened the head bolt, then adjusted the valves and then attempted to start the car. I had initially thought he went straight from tightening the head bold to starting the car..... so it sure seems like the valves could be the ticket. I am hoping! Well backing off on the valves helped me at least get an idle back! Pretty rough and gutless when I step on the peddle. I am now starting to think the head gasket is messed up....fair amount of oil right back by that left rear head - enough to drip down to the ground. GRRRRR. Thanks again for the help. Darcy |

I think most people just run standard Felpro gaskets in street motors... there are a few copper ones out there for the more extreme builds. |

Felpro (y). I think you should check to see if the deck/head needs a skim, could possibly use this chance to bump up the compression. |
