i think i have pushrod knock. how much would it cost to fix it? 1993 camaro 3.4L V6

would it be more cost efficient to drop a 3.8L into it?

 

it could berod knock(connecting rod) meaning spun bearing, piston slap, lifter tick, no such thing as pushrod knock. pushrod is a rod that sits on alifter that rides on the cam, and goes up to the rocker arm to open and close the valves. they dont make noise.

 

heavier oil for right now. From what I understand and have taken from other posters, is the 3.8 is a real mother to work on in these cars. If I where considering engine replacement I would go with stock or upgrade all the way to a v-8

 

Where is the noise from, the heads or down inside the block?

 

do tou have a drop or rise in oil pressure if so most likly a spun bearing

 

also you can cut open your oil filter with a chisel and cut out about inch of filter wrap in arag and squese in a vise gently and open to see if it full of metalif so teardown would be nesc

 

drop the oil pan....

see if there isany metalshavings on the magnet... (black square inside the oil pan)

if there is;you prolly spun a rod bearing.

 

my oil pressure gauge is broken. i think it is a spun bearing
