Oil leaking from 350 vortec in a 1998 chevy silverado z 71. a friend told me it was the rear main seal but with closer observation it looks to be coming from the left rear side of the block right above the starter. doesn't leak a lot only about a quart every oil change but still would like to know what it might be and how to fix it.

It could be coming from the valve cover, the only way to check for sure is to clean the area with dergreaser then run the truck and check it closely, this may require a mirror and trouble light

Instrructions on replacing a rear main seal on 2004 kia rio


Oil leaking "in" your valve cover? Where is the oil at/coming from? And, to answar your question, rear main seal is a real job! Requires removing transmission, flex plate/fly wheel! It is the crank shaft seal, on the "rear" of the engine!

How do you get a rear main seal off. A friend siad you can use a scew driver to pop it off this is a toyota celica gt 2002 oh and what do you look for on the seal to determine it is bad will it only be...


Changing a rear main seal is a major repair. The transmission must be separated from the motor to get to it. The way you know a rear main seal is bad is that it will be leaking oil between the back of the engine and the front of the transmission. If it is not leaking oil, then leave it alone. If it is leaking then you have two options. Have some replace it by doing what I have just told you (call around, its probably pretty expensive). Or you can do what I would do, Just check your oil ALL the time and add oil when you need to. Put some cardboard under your car where the oil drips and leave it alone until you want to spend the money.

My Chevy 2002 Tahoe is leaking oil. They told me


this truck is equipped with an aluminum oil pan you could have 1 or several things going on... a stripped drain plug which is causing it to leak or it may be a leaking front seal or a rear main seal. If it is a front seal it is not to labor intensive. But if it is a rear main seal leaking it will require the transmission to be removed since the seal is a 1 piece rear main

1998 Silverado 1500 Rear End Howl/Leak/Clunk/Vibration Pinion


A pinion seal leaks for one or boyh of these reasons. A worn pinion bearing or a driveshaft vibration, Sounds as though you have both. Do not confuse tire howl with gear howl, be sure.The rear end can run 3 to 500.00 if not more. Ck the gear oil in the rearend for metal content. That will tell you alot. The hard shifting is generally from a sticky spool in the trans valve body. Have the trans serviced w/new oil and filter. The new oil often cleans the moving parts of gum and varnish buildup.in the valve body. One more thing, the rear ends take a special oil and additive if it's a limited slip or posi lock. You will have a popping/binding noise when turning if the wrong lube is install. Have your driveshaft aligned and balanced at at driveshaft shop.or you will end up tearing up the tailshaft on the trans. Good Luck

Turns over but dont start let off key and sputters 3or4 times 1998 Vortec 350 Chevy Z71 4x4


The freeze plug you replaced was due to rust or was it pushed out by freezing temperature? These plugs are not designed to protect the engine block from cracking during freezing temperatures, they are there to remove the sand from the block after casting it. I would drain your system completely and flush out the radiator thouroughly and fill with plain water, then run the engine and see if oil gets in the water, if it does and the plug was out due to freeze, then your block is probably cracked, although you could just have a head gasket leak. Oil pressure (40psi) is higher then water pressure (17psi), so getting oil in the water is always more prominent than the other way around. Flush out the system and let me know if oil returns to the water, hope this helps

Hello, it seems that you have intake gaskets leaking. I'll bet you have the vortec 350. This is a common problem with the vortec, Gm uses plastic intake gaskets and they blow out over time usually to the externally but yours is internally.It is a pretty easy fix for the average mechanic to do. Thank you
