I have a 1998 z-71, the low pessure valve stem on the ac is leaking, i have tried replacing the stem. Still leaking, also can the valve stem on the high pressure side be replaced?
Not without spending alot more money than you want, because you have to have a shop release the ac pressure if there is any, see if you can find the complete hose, then get it re charged, unless you are certified it cost quite a bit ... 1999 Chevrolet Silverado 1500
I have a 91 chevy, 2wd with a 350. My oil pressure gauge reads 0 at idle and goes up to 30 when I get on it. Truck runs great no pings or knocks. Took off the valve cover, usually oil just trickles out of rockers in my past trucks, it was shootin out, actually got some on my exhaust manifold and fenderwell. Looks like I have great oil pressure, but gauge says otherwise, should I be worried?
Sounds like you have good pressure but would not hurt to put a mechanical gauge on it to verify that. Chances are that the sending unit is going bad or a passageway to it is obstructed. If pressure is good, change the sender and put some marvel oil i ... 1991 Chevrolet C1500

My 1993 chevy s10 was running with low oil pressure so I pulled over and turned the truck off and on to see if the pressure would increase. The pressure increased I pressed the gas got running then I heard a pop of some sort and the truck lost all power. Now the engine starts sounds fine with no clanking sounds. The truck barely moves when I gas it as if the emergency brake were on. I changed the transmission oil and filter in hopes of a clogged filter. Please advise.
I believe you have the THM 4l30-E ,a fairly common tranny used in Rodeos, Cadillacs, BMW's, a few other cars. It has a failsafe on it, if something goes bad, like yours did, it goes into limp mode which is just enough power to get you home but not r ... 1993 Chevrolet S-10 Blazer

Low Oil Pressure on 1992 Chevy 1500 Pickup Truck

Alrighty. I've asked this a few times before, I have more info now. CHEVY 350 K1500. 1993. Replaced intake gaskets, (bad oil leak) dropped a small amount of coolant in with oil while doing so. Changed oil before starting truck. Since then the pressure will read fine while cold, but as the truck warms up, the pressure drops, eventually all the way to zero, and will stall the truck at idle. I've replaced Sending Unit, Oil Pump, Oil Screen, Cam Bearings, Mains/Rods Bearings. and about 5 oil change

Low oil pressure (gauge is showing low pressure), small leak...but not losing oil fast or "dumping oil". Knocking noise in the engine. When you look at the engine, there is oil on the drivers side of the engine...also, knocking seems to be on that side. Thoughts? Just bought the truck and I love it...but this has me worried. Hope it's not a "replace the engine" fix! Thank you!

Have a 1999 Z71 chev truck with 5.3 L engine that has fluctuating oil pressure. Started with low oil pressure after start with engine clak that disappeared after it warmed up. Changed oil and found sludge in crankcase. cleaned as best we could and blew back through oil filter housing. Now engine shows ''0'' oil pressure after start for about 10 seconds then goes to mid range on gauge. After it warms up, oil pressure starts to drop and engine appears to labour intermittitently.
In some cases where the oil is not changed properly, the oil pump screen maybe plugging or your oil filter is defective. Fram is a good filter. If there is no problem found, replace the pressure sensor. ... 1999 Chevrolet Silverado 1500
Oil Pressure I own a 2001 S-10 Chevy Blazer 4x4 and my oil pressure hit 0 yesterday. I checked the oil and it was about 1/2 quart low if that. I had the engine replace about a year ago. The pressure will start to go back up at ~ 2000 RPM but it only hits about 10-15 pounds of pressure. Could this be the gauge or the pump going out?
