last week we determined that some of my oil leak problem was 4 bolts holding my carb intake to the heads, so we applied sealant and 3 stopped leaking. on Saturday I thought i'd address the last one that did not stop leaking, so not only did I add sealant to it again, I decided to use a longer bolt because the other 3 were longer. I used a 1.5" bolt but it turns out the other were probably 1.25", the max that should be used. so anyway, monday go for a drive but power is weird, I figured it had to do with engine being cold and I just changed the fuel filter and thought maybe there was some starving going on, but 30 minutes later I decided to go back home and figure out what was wrong. anyway, yesterday I pull the valve cover off to find a cracked valve rod that I retrieved from the head with a magnet on a stick but I had to remove the intake to put the lifter back in the head. anyway, it is all back together but it revs ok in neutral but under load it is either valves or knocking. what you think? anyway, why does a guy with so little mechanical prowess own a 914, who the hell knows. i'd like to think the noise is due mostly to timing cause I of course had to pull the distributor. and I never put a tdc mark on my flywheel or crank balancer, need to, asap. I first thought it was vacuum advance problem but vacuum is pulling thru hose.

Got just the motor to replace yours.

May require some metal fab.

Nothing like doubling up (IMG:style_emoticons/default/biggrin.gif)
