if my head gasket is blown....do i lose compression on the head?

yes

 

if i change the head gasket....how many pounds of torque do i have to put on?...and do i have to torque it down in patterns?

 

depend on ur model more info on car etc and yes it have to be torque in patterns if not u could damage ur head

 

my car is a 93 LS b18a1....know any sites that show how much pound i got to torque in?

 

i forgot but i did my headgasket on my 93 ls last winter i think it was 69-72lbs i let u know

 

iight thanks man....does anyone else know a site or something i can check out?...

the torque specs on a b18b is 63 ft lbs for head. it shouldn't be too far off from your specs. if you cant find a pattern. your best bet is to tighten starting from the inside and go in a star motion (like lug nuts) and work your way out. vis versa for removing a head off the block.


blown head gasket = sweaters and jackets in summer time heat.

 

yeah thanks....should 61 pound be good for the head?

 

61 lb/ft is the stock head bolt spec on my B18A1 head.

Loosening the head bolts should be done with 1/3 turn on the ratchet at a time beginning with the outside bolts alternating sides working in.

Tightening, you would begin in the middle and work your way out alternating sides, just go to 20 lb/ft, then 40 lb/ft, then finally 61 lb/ft.

If your saving all this money by doing the work yourself, how come you don't go to the auto parts store and buy a $20 Haynes manual for your car?

 

i got the torque....i changed the head gasket...my car still wont start....i dont even know why...it just cranks...anyone have an idea of what happen...i bought it this way when i got it ..it had no oil in it....i think the motor gone...any suggestions?

 

Well, you have to have fuel/spark/timing for it to start.

Any one of those will keep it from starting.

Start with the basic stuff. Does the fuel pump turn on? Is the distributor any good? Blown fuses?

So many things man. You've got one heck of a project there

Was the head gasket blown when you bought it too? There could be so many more problems..

 

from the sounds of his car experience level , now he has timing issues. thats my guess.

 

did u adjust ur valve lash bro that happen to me too.did u do a compression check

and yes the pump turns on...fuses are still good...and new distributer

 

20,40,60,60? lol. considering anything less than 130 your engine might not start , your definitely having compression issues. make sure you hold the throttle wide open when doing compression check.

 

im going to try to stick a new head in....when i bought the car....he told me "the heads were shot"...dont know what he means...but im guessing somethings wrong with the head....ill update when i put it on...

 

bro try the valve lash before you change the head im pretty sure you are haveing the same problem i did when i did my compression i had 0 on all four after did a lash it had 170-180 all four

do you mean adjust my valves?....the valves in my b18a head might be bent....i think my block is gone..dont really know yet...when i checked the dip stick....it was dried....so i mite need a whole new motor

 

yea valve adjustment same thing, damn hope u figure out what is wrong it can be big or small
