s10 knocking

[blaster20001]

I:Ijust figured id ask cause no 1 else could tell me anything well i have a 1996 chevy s10 with a 2.2 that has a knock to the motor but the head has been replaced and the lower bearings cause everything else met spec. do u guys have any suggestions or anything any help will be appreciated

 

[BlasterKX]

was the rod bearings replaced also? and does the knocking go away when you give it gas or speed up with the motor?

 

[blaster20001]

yes they where replaced and it sometimes isnt as bad as other times

 

[stnditup2]

well the 1st problem is thats its a 96. Nothing bad for the bodys but the motors in 96 where built bad. The 2.2 motor I would never own one ever.

 

[BlasterKX]

when they first started with the 2.2 it wasnt that great of design. is there anyway you can give me a better description of it?? are you sure its not more of a ticking? and who replaced the bearings?

 

[blasterman312]

can you tell if its coming from the bottom end or the top end?

 

[blaster20001]

it sounds like the bottom end and everything whaz done professinally and it a massive knock not a tick

 

[blaster20001]

also is there any motor that would bolt up to the tranny that i could run in it?

i had the same problem with a 94 corolla, it was a terrible knocking and after a few days it put a rod through the block, f*cker still ran though. i say blow it up and put a v8 in that f*cker. I:I

 

[blasterman312]

Is the truck, as a whole in good shape?, if not, run it into the ground

i had a 97 S-10 Mark 3 edition with a 2.2, and it ran great! the only problem i ever had was somthing to do with it idleing up and down, but other than that it was a great truck, even ran pretty hard and never had a problem! but hopefully its nothing to major but usually when its a knock its not good! Anyone ever seen anything of GM's that were the Mark 3 edition? i think they made a few vans that way too!

 

[blaster20001]

ya i think im gonna tear it apart and see whats up cause the trucks only got 58000 original miles and its clean so i think it will be worth it

 

[rls67]

make sure the flywheel bolts are tight and also torque converter bolts (if it is an auto)

 

[blaster20001]

ok will this make it have a knock

 

[glh85]

loose mounting bolts will make it knock been there done that twice. just for sh*ts and giggles pop off the serpentine belt and make sure its not one of your pumps. (AC, Water pump, power steering etc.) lot cheaper and eaiser thatn motors comin out.

 

[blaster20001]

ok thanx

 

[samolia]

it could be piston slap too what you do is crawl under the truck and if its louder underneath it then you have a piston slap issue.
if that motor goes just put a 2.5 in it much better engine more durable haha.

 

[blaster20001]

ha will it bolt to the tranny and will it plug in

 

[00blasterRESTO]

mmmm,, sure it isnt out of the top?? i would think that it could likely be that your lifters are out of adjustment and they will knock something crazy dependin on how far out they are.

 

[blaster20001]

ya its the bottom end its louder then loud
