Alright I am a fairly techinal guy and i just blew a head gasget.

Rather than wasting the time and effort just changing the gasget i would rather rebuild the motor.

My plans over all is to take it out tear it down and get the block cleaned and the crank and rest balanced.

now once i determine the over bore needed and the oversize of bearings needed Do i really need to worry about measuring tolerances? if they are out of spec all i can do is take it back to the machine shop correct?

Otherwise is there any other tips for someone putting together thier first motor solo or ever even.

Time is not an issue I am using this as a learning experiance

 

yes, you need to measure tolerances. what makes you think you have to oversize bearings? just curious. you also need to clean, clean, and clean! make sure you use the proper lubricants in the right places to insure long engine life and prevent dry start-up. i would recommend changing freeze plugs while the engine is out. you need to replace oil pump and water pump and you need to address the head (e.g.; valve stem seals, check valve guides, re-seat valves, etc.) and possibly head bolts (or studs whatever may be the case).
make sure you have the proper specs for torque and have a good set of torque wrenches which have been recently checked and tested for accuracy. have a 'clean room' for assembly for 0 dust tolerance. and clear an area for all of the parts to be placed in a way that is unobstructed. and a tip would be to videotape the tear-down if your memory is bad.
good luck!

 

I was just saying if it was preped would I really need to worry about them, because there isnt much i could do about it.

I will honestly only be working with a haynes manual so i will likely track down a dealership shop manual

 

yeah, there is something you could do about it! hey! what are ya workin' on anyways?
