aight i took the driver side valve cover off today to see if im getting oil to the top.i am getting nothing out of the push rods but my oil gauge says i have 60lbs.

 

You may have a bunch of sludge in your motor.

 

The top end doesn't usually get a huge amount of oil. With the engine running and the valve cover off, some oil may get sprayed off the rockers but not always.

Pick an area that looks dry and pull a rocker off. Pull out the pushrod and see if you can blow through it or force compressed air through it.

The hydraulic lifters need a good oil supply but the rockers and the rest of the valve train only needs oil for cooling so they don't need a huge supply. They normally get oil through a splash method with some oil being forced up the pushrods.

I run solid roller lifters. I have restricters in my block to reduce the amount of oil that reaches the top end of the engine.

 

the engine is clean,the engine is knocking so it got to be the oil pump.last weekend i replace the rod bearings i pack the bearings with grease put everything back together.crank it up,no knock at all but after 10 mins running time probably after the grease burn off.the knock came back slowly

so this weekend im going to replace the oil pump should have done it last weekend but i thought it was good since the gauge was reading nice psi.

 

Did you measure the clearance when you replaced the rod bearings?

 

no i didnt, i know i should have but all the journals look fine,well the last rod bearing did spun the only one,if it is worn down can i put an oversize bearing to fill the gap.

but if it worn down wouldn't it have knock when i first fired it up?

 

If you had a bearing spun in the rod, then the rod needs to be resized or replaced, and the crank journal is trashed and needs to be ground undersize, or the crank replaced. All you did was waste your time and a set of bearings.

 

yeah i know i was trying to band-aid the engine.

does this sound right,aight today i just turn the engine over and the engine didnt crank and the oil psi gauge was reading 35lbs?

 

Yes, you should be able to build some oil pressure during cranking. It doesn't sound like there's anything wrong with your oil pump.

 

well the heads are dry,and when i took the rod caps off they was almost dry to.

really i think my gauge is just mess up,60lb when running when it hot it goes to 10 then give a lil gas it stays at 60 again idk.im going to get a mechanical to be sure.

but i think im going to save another 150 to get the engine overhauled.i have enough to get the rebuild kit already.but dont have enough to get the crank,might have to sell my RF amp lol.damn this is a lot of pressure for a 17 year old...

 

When in doubt, install a mechanical gauge and recheck pressure. If you have 60 psi then there isn't anything wrong with the pump.

From the sounds of it, the engine is trash. It's cheaper to install a replacement engine than it is to fix that one if a rod bearing has already spun. A spun rod bearing will have heated up the rod end and distorted it. The rod needs to be resized or replaced. Parts are cheap but the engine needs to come apart to have proper machine work done to it. All that time and labor will be more than a replacement engine. If you spun a rod bearing, there will be metal throughout the engine and oil galleries are probably plugged. The metal from the bearing will also contaminate all the other bearings in the engine.

 

well i cant afford to buy a another engine.could, but then i would never get the camaro on the road,instead i be driving a 1990 ford tempo 99hp

so i decided,the car don't smoke and the cylinder walls wasn't scared a bit so im going to replace.

crankshaft kit
oil pump/screen
freeze plugs
rear main seal
intake gasket
head gasket
timing chain kit


total $267 before tax
i have a use set of connecting rods so i hope this will solve the problem and last for awhile until i get a full time job..

 

So what about the engines balance?
Are you gonna personally press your old pistons off the bad rods and onto the other rods?

 

what do u mean engine balance?

and no i don't have a press so im going to take the last rod to a shop or have it redone.

 

The reciprocating parts in an engine have their weights matched and the crank counterweights altered so that the thing doesn't shake itself to pieces. Swapping a stock rod for a stock rod might be ok.

 

oh ok,i probably just have the rod redone

 

ok the engine is out,and the crank is gone lol figures, but would the connecting rod be good still if the bearing just spun on the crank like it did? it looks normal lol

 

when you say you "packed it with grease" what type of grease did you use?

 

No

 

i pack it with assembly lube..

ok just wondering,well i find a new one for 26 at my local auto parts and they also going do free pressing..
