Triumph TR6 - Alloy Valve Cover

Has anyone purchased and installed an alloy valve cover recently. If so, were you pleased with quality. Where did you purchase yours/Moss, VB, RF? I looked at a 74 TR last weekend at a show that had an alloy cover with no change to ther EGR valve. Thought based on reading advertisements that the valve needed to be removed.

Shawn,

Mine is a 73 and it doesn't have EGR. But I do have an alloy cover and have had no problems with it. I've had it for 2 years. I bought it new on ebay. I believe it is the same one Moss sells. It was a pretty good price. It's very well made...fairly thick aluminum with no thin spots. Keeps a good shine. I like it.

I have one on my car that was purchased many years ago from Roadster. Seems like a decent piece and definintely quiter than the stock cover, the aluminum really damps down the valve train noise. I cannot speak to the EGR valve issue as there is no EGR valve on a 1971.

However, I can tell you that when I installed roller rockers that it would not clear the rockers. I think all of the newer ones do not have deep recesses where the hold down studs come through, but this one did and that was where they fouled the rockers. I wound up making a drill fixture patterned off the cover. I then threw the cover upside down on a milling machine and machined the bosses away. Next step was to turn some plugs for the resulting big holes from 6061-T6511 rod stock. Then made a weld fixture from a piece of lumber and some brass rod stock as stand offs for positioning the plugs and welded them into place. Applied the drill fixture and made holes for the hold down studs and after a little bit of grinding down the excess weld metal had a cover that cleared the roller rockers. A good cleaning and a nice spray of red wrinkle finish later and it was Triumph Testarossa time.

Shawn,
I also have one. Definitely looks better than the OE cover. Bought mine at BPNorth west and was lowest cost of anyone. I put a baffle inside the cover where the breather vent hole is. I had too much oil splashing up and out the hole into my '71 excuse for emissions control.

Make a little baffle that is very flat to the inside wall of the valve cover. The baffle should be as tall as the side wall of the valve cover. Cut out a few slots for air movement. Drill 2 holes in the baffle and loop a piece of wire through the holes and then the 2 ends exit the vent hole tube and fold these ends around so that when you put the rubber hose on the vent tube, the hose holds the baffle in place.
I hope I am clear.

I got mine from a shop here in Seattle (Autosport), but I think they get most of their stuff from the usual places like Moss, VB, etc. But even with local sales tax, their prices are usually better than mail order. (So, I don't really know where they got my valve cover from, but it looks like the Moss cover.)

The cover was pretty nice, but I did spend a couple days buffing it. I am not sure why now though, I must have had extra time?

And I was able to bolt it on with my EGR, despite the warning in the catalogs. I have since removed my EGR and most of the emissions BS though, since I got tired of searching for air leaks.
