The Force Awakens...

That Permatex Ultra Copper High Temp RTV is the Best Stuff to use as Grumpy said 2 years ago to me.
#2 on my list is Permatex Ultra Grey RTV.
Everything else gets a coat of Permatex Aviation gasket cement.
Pontiac V8 engines I Edelbrock Gasginch.
Fel Pro Race Head Gaskets I like putting on dry.
Grumpy Likes Ultra Copper spray on headgaskets.
I use It on LS headgaskets to.
 
Since we are on the subject, for years I could never get the rear end cover gasket to stay sealed on my 95 GMC truck.
The gasket would get sucked in by the drivers side axle tube. I even bought a brand new cover even though the stock one was flat.
I tried with no gasket (Permatex only), dry gasket, gasket with Permatex, Victor Tuff Cork gasket (steel core) with and without sealant, and
even replaced the bolts with studs and nylock nuts. It wasn't until I found this stuff until I finally got it to seal.

Permatex® Gear Oil RTV Gasket Maker

OEM specified. Specially formulated to withstand the harsh gear oil environment found in differentials and transfer cases. Because gear oil has friction modifiers that break down normal RTV and cause leaking, this specialty silicone has been tested to OEM specifications to ensure complete sealing. As a gasket maker, it seeks and seals leak paths that cut gaskets cannot. It can also be used to seal cut gaskets.

Apparently, synthetic gear oil and/or the friction modifiers love to eat regular silicone.
 
Having some trouble loading this episode #9 of season 2 with a 1969 Corvette

Right now you can see the end of this show, for some unexplainable reason I can’t copy the whole show??? Perhaps someone here can help, or you may have already seen this - oh well, I tried!

Sometimes Videos do not want to copy easy.
Have to try another method.
When I have problems I get the wife to help.

Nice C3 like Doriens.
 
OK, someone correct me if I'm wrong. Look at the SBC timing cover. The part that holds the gasket in place in tack welded on in only about 5 places.
In the past when using the conventional 4 piece oil pan gasket set, the first thing we did was to put some Permatex in that channel, before the front seal went in there. That sealant would also seal any gaps between the front cover and that tack welded on seal holder - NO LEAKS.
Now we use that one piece silicone gasket with no sealer - and have leaks. My bet is the oil is getting in between those 2 metal pieces, bypassing the seal, and has a straight shot at leaking out.
Am I making any sense?

You might be onto something. I used NO sealant on the lip under the timing chain cover. NONE. Only a large bead on the "four corners". I thought that was the standard way to do this. I am not using a single piece gasket at the moment, but a traditional four piece of rubber and cork.

This weekend, I may try again with a news set of pan gaskets and... some sealant ! I don't think I'll be able to find a single piece blue gasket here.

Any and all tip on install welcome ! I don't want to have to do this a third time.
 
Will do. I have some of that. Block side only?

Where would the RTV go? Under and across the timing chain cover lip? And what about the rear?
I use Gasginch on both sides of the gasket.
Then a thin coat on the block and oil pan rails.
Let them dry till tacky.
Gasginch has Alcohol in it as a thinner and evaporates.
When dry its tacky.
Before its sets up fully place the cork or paper gaskets in place on the block.
Often need trim the gaskets with a razor knife after install.
Apply RTV of your choice to where the rubber and cork/paper gaskets meet. 4 corners..install the oil pan.
Tighten the pan center to outwards in a criss cross pattern.

I will try one more time with my 1 piece gasket by using sealer not only in the 4 corners, but under the front and rear seal areas also.
If that does not work, then I'm going back to 4 piece gaskets. I never had any trouble with them sealing.
But, I use Victor Tuff Cork brand gaskets. The side rail cork gaskets have a steel liner.
Looks like they might be getting hard to find. But I found these on ebay:

The last one is for 1985 and up with the PASS side dipstick. The other two are for DRIVERS side, and I'm
sure that the difference in the part numbers (XTC and ZTC) is for the thin and thick front seal, but I'm
not sure which one is which.
 
Well, Gentlemen, an interesting development. I went to the only "Speedshop" in Belgium. It turns out they had a one piece oil pan gasket in stock AND a trans mount. So, hopefully this weekend, I will have this squared away. In terestingly, the instructions recommend some RTV in front where the block meets the oil pan and a dab in the back where the block meets the cap.
 
He wrote this the last time he was on last Saturday. I think he is in the US.

Ha, I will be swinging by CT. I have a three week TDY in Long Island NY but need to swing by CT
 
Hey All, sorry for dropping out...things have been a little crazy. My travel was cancelled then re-approved 2 days before I left. Wife was not thrilled - nor was I actually.

Now two snow storms in a row? Teleworking today but I will be online later... ;-)
 
Yes, I am on Long Island - LOTS of defense companies here... used to supply Northrop Grumman
 
This week and next - just the area and a couple of cities in Connecticut
 
Even with a brief stop, you should quickly see how Connecticut is DEAD LAST in recovery from the recession. DEMS just keep on spending........
