Getting ready to rebuild my motor on my s10 have 94k miles on it and been leaking oil and has coolant in oil (kinda like chocolate milk color) so I decided I'm gunna pull motor and just rebuild it, looking for info as for what to replace while rebuilding it, what's better to buy etc. Etc. Just looking for more info to buy for rebuild...
Gunna do cavi intake manifold
P&P head, and mill it some
Maybe do a reground cam
Roller rockers
New push rods/ springs (havnet found aftermarket ones)
New valves/ guides
New pistons/bearing
Re use rods
Want after market high volume oil pump
Looking for a reliable dd with great gas mileage, but can't find were to buy these parts at or even prices, and looking for more info on parts etc. Etc.

Re: 98 S10 2.2 Motor Rebuild ????

To get great gas mileage , keeping the truck close to stock is your goal. Minus a few things like air intake, exhaust, etc..... as for parts, there are a ton of different websites that carry rebuild parts I will post a few links below

I know I'm gunna do pulleys, fan, intake, headers, coilpacks, wired, plugs, but thought by p&p and cam would help motor breathe better thus gaining power and mpg?

Re: 98 S10 2.2 Motor Rebuild ????

Thats debateable there, depends on what profile cam you go with. Most of my experience with cams comes with the V8 chevy motor and im not as fimiliar with the cams for these little tu tu's. If this is a daily driver I would stay close to stock, considering the way gas prices are going through the roof. I run highergrade ethanol in mine mostly now. Its a flex fuel. and its 100 percent stock. My daily driver. If I were to have the money, and wanted more horsepower, i would just run a V8, but with this being said it would not be a daily driver. The choice is yours, Thos parts you mentioned above seem to work great on these little tu tu's. I am considering the throttle body swap myself along with the E fan, There should be plenty of post's on cam's and what i call Hot Rodding.

Re: 98 S10 2.2 Motor Rebuild ????

doing the things you plan on doing in order to increase air flow is going to also increase fuel useage

so......

in order to keep fuel mileage good you need to keep it close to factory as possible

and rebuilding a 2.2L just to keep it factory is not gonna be very cost effective but i guess should be less cost than a brand new one from GM

so hmm..

if it were mine i would go with a good used engine from a yard, you can find lower miles ones for less $ than youll spend on parts and machine shop labor to rebuild your blown one, in which i wouldnt trust very must with it having oil and water mixed

thats a real bad sign and a real bad starting point..
overheating, and or cracked parts and so on...


have fun!
