Engine Rebuild. Tools needed with questions for the Pro's
 
Well it's about 3 years later and i finaly ordered an engine rebuild kit. I have a spare Engine That has some 80k miles or less i want to rebuild. I just have a few questions for the pros who do it for a living and maybe some tips

QUESTIONS:
1. Will i need new Valve springs since the engine hasent been cranked over much(turned about every 6 months or more)
2. What are the must have specialty tools i will need for the build besides basic tools
SPECIAL TOOLS I HAVE ALREADY: Gear Puller, Feeler Guage, Soft blow hammer, Redline Assembly lube, Torque Wrench
3. What's the best way to clean my engine and get rid of buildup inside and out. (bead blast? Parts washer, powerwasher w/ degreeser?)

4.What Mods or upgrades should i do that wont break the bank as im not workig right now.
5. Are Some tools worth even investing in that otherwise i could take to a maching shop. like Purchasing a micrometer and Calipers(starrett) to measure crankshaft, pistons and whatever else i need to measure. Bare with me im sure ill have more questions as i come along


All input is apreciated and welcomed. Its been a long time since i wanted to do this and snce im unemployed i finaly have the time but i want to do it right and im sure im forgeting a few small things that need upgrading 'While im in there"

Regards
J

Well here is what i've come up with so far.
Oil Pan Baffle Upgrade.
Cam Upgrade ( 85 cam with more duration?)
5 Angle Valve job (what ever that acutaly is and does)
Lighten Flywheel( machine current or buy new?)

Port Matching/ Gasket Matching. doesn't seem to hard to do with the right tools

So far that's what i've come up with. I'm not going to take the car to the track. And since it realy is my first car purchased with my own money i want to take care of her right so she does the same for me

Anybody port match/ gasket match thier intake manifold to the head on here?

80K or less? These engines are very tough. Unless it was severely abused, or maintenance was highly neglected, it should not even be close to needing a rebuild, especially if it is an N/A. My (never rebuilt) turbo has 137K and still reads 145psi in all cylinders and does not smoke, or make any noises, other than a slight whine from the timing/balance shaft belts - but that is normal. If it hasn't been started for a while, the lifters make some noise for about 10-15 seconds, then go quiet. Oil pressure is also "way up there" on the gauge.

If you KNOW there is something mechanically wrong with it, then by all means, do it. If not, save your self the cost, the hassle, and the possibility of making a mistake. Keep the things like "don't fix what ain't broke" and "leave well enough alone" in mind.

Yeah looking back at some previouse posts of mine the engien had 84k on it and its been sitting for about 4 years now. and being turned over now and again. I wanted to rebuild my current engine but since i only have one vehicle I thought i would build my other motor. My current engien still has a nice (ugly) lifter noise. And the tune up i did to it resulted in me finding that a piece of ceramic from the Spark Plug had broken off in the piston and was no where to be found (#3 pistion i think) anywho here were the compression results taken almost 3 years ago on the engine in the car now.... still trying to figure out how to check compression on my motor that's on the stand if its posible.

Cylinder #1 179 psi

Cylinder #2 181-182 psi ( hard to tell exactly)

Cylinder #3 120,150,170, Finaly 175 psi ( psi kept rising)

Cylinder#4 179 psi
