Where can I get a head gasket for a 6-1 Metro Engine?

[vtmetro]

I haven't removed the head yet, but need to because I have a broken stud in the exhaust port that I need to drill and Easy-out off. I want to do that on my mill, rather than with a hand held electric drill.

I see a few ads on ebay for an 8-1 gasket for "listeroids", but I don't see any mention of a 6-1.

Any help would be appreciated...

The 5/1, 6/1, 8/1, and twins all use the same head gasket as long as the listeroid is the same bore and head design as the original CS. Some listeroids are 5 stud heads and some are 7 stud like the original CS. The only other difference could be some listeroids, usually 10hp and up can have a modified direct injection head. I think that is unlikely on a 6/1 Metro. Just need to pull the valve cover and count the head studs. A 5 stud will have the 4 large ones in the corners plus the rocker stud. A 7 stud will have those plus one on each side.

Thanks @broncodriver99. My Metro has 5 studs.

So it doesn't matter that the bore is 4-1/2" (114mm) on the 6-1 and an 8-1 and 10-1 gasket is advertised as a 120mm?

Just checking before ordering......

That 120mm bore gasket is for the 10/1 and up listeroids. Not sure why they have it listed for an 8/1.

This should be the correct bore although it is a 7 stud version: https://www.ebay.com/itm/264527269100

I have never bought from DEV in India but I have dealt with Stationary Engine Parts in the UK.

They have the correct gasket for a 5 stud but shipping is pretty steep. https://www.stationaryengineparts.com/Listeroid-6-1-and-8-1-Copper-Head-Gasket-For-5-Stud-Heads.html

You may want to message DEV through ebay to see if he has a 5 stud version. I hear he is a pretty responsive seller.

You may also want to try Jim up in Canada. He may have them as well. http://www.justliveoffgrid.com/SpareParts.html

Almost forgot, there is also a new composite style gasket. I have a couple on the shelf but have yet to need one. I have heard they work well. Already in the US too.

Thanks again @broncodriver99, I had sent a message to Dev on Ebay and they replied back that the 7 stud version would fit my Metro, so I ordered it.

I hadn't yet seen your above comments and the alternative US composite version. That one would have been less expensive and quicker than ordering from India. Oh well. One note though -- that one states 4.62" (117.3mm) bore. This all all a bit confusing.

I guess I could also possibly re-use my present gasket if it isn't damaged in removal -- per forum thread here:

I received the gasket after waiting a month from Dev in India. It was all crumpled up, since it was simply sent in a thin cardboard off-the-shelf type box, with some layers of plastic wrap around it. No shipping container.

The inner fiber layer of the gasket was torn, so there was no way to even straighten it out.

Complained and got a refund for it. But a total waste of time.

Jeez, why would they ever think that would survive?

Following up on your previous post about the bore size of the head gaskets. I believe the head gaskets are a little oversized on the bore to allow for a couple of things. The first is that when the fire ring(the metal ring around the inside bore of the gasket) crushes during installation it will close up the bore dimension a few thousandths. Second, to allow for boring the cylinder oversize. Prevents needing a different head gasket for different amounts of oversized bores.

I have some spare parts in the garage and happened to have a couple of the composite gaskets I linked on Ebay as well as an Indian produced gasket kit. I don't know where I left my calipers and all of my other sets are at my shop 30 mins away. I pulled some measurements with a tape measure. The composite gasket measures a hair over 4-9/16" which should be right on the stated 117.3mm. The Indian copper head gasket measures about 4-5/8".

The Indians just don't advertise actual dimensions. Well..because then they would have to meet an actual spec. LOL.

Seems the composite gasket should work just fine. Hope the info helps.

Buy the improved head gasket made by a pro on ebay. these have been out for 2 months. they will not leak or blow. I will see if I can find the link. Dev is garbage in 99% of what they sell.. There parts are just as bad or worse that came in your engine originaly.. After 40 years of cloning listers the indians have not even bothered to update and improve these easy parts to make.. They suck. Statinary in england is a bit better as they seem to know the one or two engine factory's that make a slightly better qaulity part
EDIT:  just saw bronco has purchased a few of the composite gaskets on ebay.. Have you used them yet broncodriver?

I also think 38ac has been selling his own specced composite gaskets for some time

Hi, somehow I missed this post earlier. Yes the bore size matters as does if it is 5 stud or 7 and wet sleeve or not. I have head gaskets in all the different types in stock and most every other part also. If interested send me a PM,

I have not. I bought one years ago that got damaged in shipping so had them send a couple when they reshipped. They have been sitting on a shelf ever since. Just in case kinda thing. I reinstalled the original head gasket on my one CS that is running.

I did give the composite gaskets a good once over and they are very well made. My only complaint would be that the printoseal material, the silicone sealant around the water passages, is only applied to one side of the gasket. So, in my mind one would either need to apply a minimal amount of sealant or gasket dressing to the bare side of the gasket.

The composit gaskets as sold by GTG are indeed very nice and are the very best to use on original CS engines or Listeroids without a wet sleeve. They will also work on wet sleeve engines that have had the sleeve stand out corrected. If not corrected the India copper sandwich gasket works better.

Just a very belated follow-up -- I was just notified that the forum moved/changed names so checked in. Back in January after receiving the crushed Dev brand gasket, and a refund, I re-used the old head gasket with the copper spray gasket stuff (Permatex? -- don't remember) per the discussion thread mentioned above here. That was totally successful, and I've run the genset several times since during power outages without a problem.

I'm sorry I didn't see the subsequent posts by @broncodriver99, @keith71, and 38ac, and thank you for responding after my last one. I should probably get another gasket as a spare.
