I need the torque specifications for my 1990 plymouth acclaim cylinder head. It's a 4 cylinder, no turbo. How many foot pounds do I need to torque the head bolts and in what order should I tighten them? Same question for putting back on my valve cover.

The torque specs should be the same but I have never heard of this before. Make sure you have the head checked for cracks & checked for warpage. It may need to be planed. Be sure to use a top quality head gasket. Good luck!

It is recommended that you buy the bolts along with the gasket. Did the car overheat and was run in an overheated condition for more than a mile ? An overheated engine tends to warp the heads and it has to be re-cut smooth. The bolts tend to come loose with time. If not replaced. Torque is 45 ft lbs, then 65 lbs , then way up to 90 lbs in sequence starting at the middle bottom 1 then top side 2 to the right 3 top ,4 bottom, then go to the other side of the number one bolt and the top bolt is 5, bottom 6, then way down to the end at the back of the head is number 7 top , 8 bottom...... Back to the front of the head and top is 9, bottom is 10.
the ignition cylinder will run you about 20$ and it is fairly easy to change you can change it yourself buy the chilton book (it will help later) and it will be cheaper than paying for labor although the entire replacement will take less than 30 min
Honestly... If you are really not that good at mechanical issues you probably should take it in... Not to be mean but the head needs to come off in a bolt sequence and reinstalled in a bolt sequence with the correct torque... The passenger motor mount,exaust,wire harness,valve cover,head boltscoolant hoses,throttle cable and many more items need to be removed......Also NOTE:... slip and tuck head gasket jobs are NOT advisable and ussually result in doing the job twice over..... The heads have a tendency to warp and also crush in the gaskets over time....The head should be checked for warpage. Also a good time to do the valves and replace seals.......in the end if you are not experienced and do not have someone around that knows aboput the job at hand you may want to have the job done by a tech... For fun grab yourself a Chiltons manual and read through........
