Default Re: 2001 Saturn L300 (L81/3.0L V6) - Rear Camshaft Cover Gasket [Removal/Replacement]

Brandon, I am offering sound advice here.

The o-rings on the cam covers are hardened rubber and must be picked out and replaced. There are rubber O-rings in the head gasket kit. If you don't replace these rings, your going to have leaking in the spark plug wells. Use only enough RTV to hold the rings in place and don't go over board. Excess RTV will simply cause problems.

Secondly, the RTV is made to be put on fresh, not dried. You will not get a seal with dried RTV because it won't flow to fill any gaps.

Third, you have way too much RTV. Most of which will end up inside your engine. Not good!

I don't know if you can rescue this process or need to purchase a new set of gaskets, but you're gonna need to clean off the cam cover again and start over. Also, the engine side must be shinny clean without and black marks. Use a razorblade held on a very small angle to clean off the debris. If the metal is not shinny, it is not clean enough to reassemble.

Slow down and the more attention to details here will make great results later. Don't neglect the PVC Oil Separator removal, inspection and DIY rebuilding! Now is the time to get that done while you have everything apart.

BrandonKastning, some background info for perspective. Although I haven't gone as deeply into engine disassembly as you are, I have removed the upper intake air parts, plastic intake spacer and other miscellaneous items for access to replace a worn t-stat. I've also dropped the xmission pan to replace the filter. Keep in mind when disconnecting those two fuel rail lines, you're not advised to replace the o-rings inside them. Guess what's used? Polymer and reusable unless specifically mentioned for replacement in service manuals if not damaged. I don't recall whether or not service manuals mentions most gaskets are synthetic polymer or using rtv as a sealant. I did not buy new intake spacer gasket or other gaskets upon examining them. The polymer gaskets do not seem to form a permanent shape in their roles and do not shrink as evidenced by being proud, protruding above the channels where they sit. I did buy a new xmission pan gasket but upon examining the original, it too is half metal and polymer. I suspect it was reusable but since I already bought the pan gasket and filter, I went ahead and replaced them. None of my repairs used rtv. No oil leaks around the xmission oil pan or upper intake areas, reusing all polymer gaskets. This is my personal experience and not representative of members experience or a recommendation. I did not see evidence of rtv sealant anywhere on parts removed that suggested additional sealant needed. When replacing the water pump, I don't recall using rtv or gasket cement. The water pump, if I recall, also has a channel to hold its gasket in place. If I'm wrong, correct me.

My personal thoughts of using rtv is that it has definite benefits where recommended but not if over used. As a cement to hold a gasket in place, fine as a thin coat would be an adhesive prior to mounting a part. In areas where a channel holds a polymer gasket to restrain it from moving out of place, a thin dab or coat can help but a thicker application may not be advisable. In gel form, it may take up room where a polymer gasket is supposed to form fit into place for a snug seal, possibly defeating the purpose of using only a polymer gasket by itself. Adding rtv may do more harm if its allowed to ooze out and break off to mix inside an engine. When removing parts from my engine and not seeing evidence of rtv use, I figured if factory engine assembly in various areas didn't need rtv then I wouldn't need it. This presumes my engine was leak free to begin with. No oil leaks or vacuum leaks. With over 106k miles, the engine idles rock steady. Even better since driving around 120 miles round trip from home to a ski area in NJ and back more than a dozen times. The highway miles allowed any local driving building up any carbon in the engine to leave resulting in a smooth idle. It helped to use syn oil too with extended oil change intervals.

Thumbs Up Re: 2001 Saturn L300 (L81/3.0L V6) - Rear Camshaft Cover Gasket [Removal/Replacement]

fdryer,

Thank you for letting me know these things. I didn't even know the dual fuel lines had gaskets. I will make sure not to attempt a replacement of said gaskets.

Polymer is the name of the material used for the camshaft covers (the ones that are hard on mine).

The water pump I previously replaced required waterproof RTV. That's what I learned from NTheFastLane (YouTube) in his Water Pump CTS video. Worked great!

Given the duration of this repair and upgrades; I feel strongly not to ease on excessive RTV. If it somehow damages something; I can laugh that it was RTV that did it; provided I get that far

Thanks for sharing fdryer and all your help!

Best Regards,

~ Brandon Kastning

If you didn't replace the o-rings with new o-ring gaskets, they will continue to leak and fill your spark plug wells with oil.

Fdryer, Black RTV was used on the cam (valve) covers on the sharp bends from the factory. Brandon's photos show clumps of black RTV near the cam sprocket that was not cleaned up. It looks like a chamfer between the flat head and the plastic cam sprocket covers. RTV must be applied to gaskets wet and then allowed to set in place with both sides in contact with the gasket/surfaces in order to form a good seal. Brandon, you said you allowed the RTV to sit overnight after you applied it with numerous Q-tips. I suggested you start over, but you did not. Know that it will likely leak!

Never use anti-seize on aluminum bolts that require torque. Torque specifications are for dry bolts. Anti-seize will change your 71 in-lbs you thought you applied to something much higher over time. There are plenty of videos on YT showing why not to use anti-seize on bolts and/or spark plugs. Anti-seize is wonderful on hubs and other metal to metal surfaces, but not aluminum engine bolts!

Brandon, ignore my advice and I guarantee you will be sorry. Those o-rings are hardened despite you deeming them fine. They will leak! Don't be crazy and go through this entire repair and not replace the defective o-rings gaskets. You had ton's of oil in your spark plug wells and where do you suspect that oil came from? Through the defective o-rings which you just ignored. I don't know why I even try to help you...

This is perfect video to explain the proper use of anti-seize.

Dizzy Re: 2001 Saturn L300 (L81/3.0L V6) - Rear Camshaft Cover Gasket [Removal/Replacement]

Readying re-assembly of certain parts of my engine; I found a hardened camshaft cover o-ring. I checked the thread to view the pictures before I re-installed them. Found it. Picture #1 lost an O-ring.

I just ordered a new gasket and will be re-doing this.

Not solved yet!

100%; and you were right on the o-rings. I will be for certain using the pick tools to pull them all out and then apply RTV next time!

Have a good day!

Brandon,
While waiting for more gaskets to arrive, take some time and remove the Oil Separator PCV module. It is located on the opposite side of the engine from the timing belt, about halfway down. You'll see two hoses connected to it one large that goes to the plastic intake bridge and one small hose that routes beneath the ECM over the Bank 1 cam cover to the intake. Remove both hoses and verify they are clean and have no rips or breaks.

I don't remember what size the 4 bolts are, but you'll need a long extension to get at them. There is no gaskets between the Oil Separator PCV module and the engine. It's just a thin layer of RTV. Once you remove the module, carefully clean it's mount and plug the holes to keep from dropping stuff into the engine. There are two ports on the engine side which I have never been able to determine where they go.

Inspect the Oil Separator PCV module. Where the small hose connects to the module, I am certain that hole will be completely closed with gunk. Just use a small drill bit to clean it out. Don't enlarge the hole, just clean it out.

You'll see a spot weld on the top (side) of the module which holds the top on it. It's a cover spot welded and that with RTV around the edge to hold it together. What you need to do is remove this top. It is made of aluminum so be very careful. I used a sharp chisel around the edge and a hammer. I also drilled a hole directly into the spot weld. Take your time locating it and drilling a hole directly into the weld about 1/4" deep with a small drill bit. The cover will eventually pop off.

Once inside you'll see the missing or baked rubber reed valve that covers one port of the module that connects to the engine. This is the PCV valve to relieve crankcase blow-by pressure. The original reed valve was made of rubber and over time they fail. What I did is cut a piece of Viton Rubber I got off of Amazon into a small (tiny) piece and bolted (lock tighted the nut) the viton into place such that it can flap over the port. It worked for me and others.

Before you fix the reed valve, clean the module out completely and sand any old RTV off, tap the hole you drilled into the cover. A small machine screw is all that needed to hold the cover in place with RTV thinly around the cover's perimeter. Allow to cover RTV to dry and then bolt and RTV the module back onto the car with both hoses connected. Don't use too much RTV because you don't want RTV falling into the engine, it would plug up your oil pump.

Rj 2000 LS2,

I believe you forgot that I already performed that repair. I also did a very good job and replaced all the hoses. I ran the engine for hours after doing diagnostics on the GM TECH II diagnostics if you don't remember with very good results on the statistics of my engine and all the corresponding PCV operational functioning.

On a positive note; my gaskets just arrived. I will update soon!

Have a good day everyone!

Best Regards,

The original reed valve was made of rubber and over time they fail. What I did is cut a piece of Viton Rubber I got off of Amazon into a small (tiny) piece and bolted (lock tighted the nut) the viton into place such that it can flap over the port. It worked for me and others.

Before you fix the reed valve, clean the module out completely and sand any old RTV off, tap the hole you drilled into the cover. A small machine screw is all that needed to hold the cover in place with RTV thinly around the cover's perimeter. Allow to cover RTV to dry and then bolt and RTV the module back onto the car with both hoses connected. Don't use too much RTV because you don't want RTV falling into the engine, it would plug up your oil pump.

Nope, I didn't see you remove the module. No need to reiterate the repair. Done is done.

Alright everyone! I have successfully removed the Rear Camshaft Valve Gasket Cover and I did such a good job earlier that my gasket is 100% just fine.

The front turned out the same afterwards!

Here are the galleries for this completed replacement!

Thanks everyone!
