okay i am dumb- so the longblock is the head- and the shortblock is the "bottom half"- and i need a "shortblock rebuild" ? did you call honda for the rebuild? thanks i am mechanically stupid- you know the friend that while you guys are turning wrenches i am the one responsible for pizza gathering and beer scavenging

 

No, "longblock" is nearly the whole engine, without all the ancillary parts (alternator, A/C, etc.). "Shortblock" is just the metal part the pistons sit in. You don't have to call Honda for a rebuilt. Almost any experienced licenced mechanic should be able to do it.

 

and they just rebuild it with oem parts? or do they just take it apart and replace whats broken or wrong? i am an idiot- i am sure they do what you ask...

 

The stock valve seats have a 4 angle valve grind. I hope they duplicated the stock valve seat angles, instead of reducing them.

 

It depends on what you want done and what needs to be done. You don't need a new shortblock unless you've shot a rod through the walls of your old one. If you've spun a bearing on the crank (or the rod), you might only need new bearings (clean up and machine the old one) or you might need a new crank and bearings. The thing is, once you open up an engine, you will see what else you might want to replace since getting the engine to that stage is the bulk of the expense. For example, you may be going in for scored cylinder liners, but if you've got the pistons out anyway, maybe you ought to change all the crank bearings since they're exposed. It can just snowball and put a bigger and bigger dent in your bank account.

 

yea its just a slight knock- i am pretty sure i will need to set bacck a few g's because once i open it up ill probably want to replace quite a few things. thanks for all the info--
