MariaAZ Posted December 13, 2003 Author Share #13 Posted December 13, 2003 My ignorance will show on this one (not much experience with auto repairs here!) Retorquing the head bolts; does that require them to be loosened first? :nervous: Link to comment Share on other sites More sharing options...
2ManyZs Posted December 13, 2003 Share #14 Posted December 13, 2003 Actually that's not a silly question.... It's one you will probably get 100 differing opinions on.....some will say yes, some will say no..If you were re-torquing the head after a recent head gasket replacement, I'd say no, since you know the bolts are lubed well, and are close to the proper torque.In your case, I'd back them off 1/2 turn or a little more, just to make sure the bolts are not seized. Besides, in your case, it's quite possible you may have to remove the head anyways, so making sure the bolts aren't seized would be a good idea so that you don't have one snapping off when/if you remove it for repairs.

ksls94 Posted December 13, 2003 Share #15 Posted December 13, 2003 even with the no compression on number 4 it should run on the other 5 cyl. try adding small amount of oil in the #4 cyl to see if the compression comes up any. my exp with being a nissan tech for 27 years tells me a blown head gasket blown only on #4 shouldn't keep it from starting need to see if you are getting spark to the spark plugs., Link to comment Share on other sites More sharing options...
