are you sure that you arent hearing the noisy injectors? and is this issue JUST first thing when its cold?

 

when it does do this it just does it after its been sitting a while no matter the temp.

 

I had a '94 Nissan Altima that had some lifter noise. It had 160, 000 miles on it and I was using a 10W40 oil. My mechanic told me to change my oil and use a 10W30 oil. He also told me to pour in a bottle of Marvel Mystery Oil. I did and no longer had a problem with it.

Also keep in mind that your oil is going to react differently in different temps.

I'm not sure how widely it's distributed, but we sell a product called Lucas Oil Stabilizer at work, that stuff works wonders.

 

marvel mystery does wonders...when i moved away from home, my dad stuffed several bottles of MM in my tool box!

 

yeah i know the oil will react differenlty at different temps but temp doesnt seem to affect it and i'm using a 5w30 since everyone said it was the best tyoe for my blazer and using a heavier oil could cause lifter noise. does it sound like i might have a broken push rod? im thinking about replacing the oil pump since the sound over all seems to coming from the back of the engine possibly bottom and that damn coolant leak is p***ing me off i just cant see any outside leak.


also to add i have noticed a knocking sound coming from the passenger side front tire area and it sounds similair to my old suburban and it had a bad lower ball joint but that was a 2wd do 4wd have ball joints?

 

what are the chances its a torsion bar? would anyone here have any experiencs with a suspension noise?

 

a torsion bar wont make noise when the truck is sitting still...a broken pushrod would only get worse, and break other things..ive broken a few ni my racing days...one of the cylinders wouldnt be firing if you had a broken pushrod.

 

actualy i was refering to the torsion bar as a possible noise when im driving

 

ok i was at the s-10planet site looking at the egr mod and it said to install i should drain the coolant so im wondering if a bad egr gasket or what not might be letting coolant in to the engine is that possible?

 

ok nevermind on that last post.... but i have now found coolant pooling up around a bolt behind the alternator. does this sound familiar to anyone?
