Hi Guys,
thanks for your help ..finally got both heads back on.Unfortunately that #10 head bolt on driver side-left cyl head got rounded in process so fo the last stage I was able to get it torqued to only about 40degrees instead 90..I will try to remove it tomorrow and pickup one from the local dealership...

Any advise on how much torque do i have to put on this bolt /follow the same procedure -15lbs-90-90? Should I get a whole new set for this cyl head instead one bolt only?


Pavel you were right about the quality of the aftermarket head bolts.. they're
notvery good at least the set I got. You can almost feel the socket rounding the head of the bolt during the last stage..
Not having another person helping you do the last 90 degrees of torque makes it very hard for one person so I followed Rangie's advise and removed the 2 rubber engine mount shock absorbers from both sides of the engine
( took me about 10 min for each side with the help of the engine hoist-jack and a block of wood works as well) .

Night and day difference once the engine is lowered a bit..you have enough space to work around the cyl head when you do the torque..
My 24" breaker bar was not long enough to have enough leverage so I used a piece of pipe and this way i can apply pressure down on the socket with one hand while rotating the bar with the other..

Impact sockets ..a must for this job....preferably a new or not abused socket..
