I think that both the copper and steel shim gaskets need that "attention to
detail".
I also suspect that uneven/incorrect liner height is the cause of many of the
problems with these gaskets...

Tr4 cylinder sleeves/liners compress no less than .001?at 100 ftlbs clamping.
Some may compress more than others. Solid copper gasket installation requires
attention to details

15:21:35Onderwerp: Re: [Fot] [TR] TR4A head gasket, 87 mm cylinders?When I
order my solid copper head gasket from Mordy, I ask that the scallop? be made
on the intake valve only. There's no reason to scallop around the exhaust
valve and reduce the sealing surface. There's always an amount of fine tuning
of the head gasket to match the scallop on the head and liners based on your
milling. Never used a steel shim gasket- too thin. Copper fire ring is a
must.On Sat, Oct 21, 2017 at 10:51 AM, Mordy Dunst via Fot <fot at

been an issue for years, and it has delayed me putting my TR3 engine back
together. I have used a steel shim gasket for years with success, but it takes
me 5 or so hours to put the gasket together, after grinding to properly fit the
bores and then fitting the copper wire in the fire rings, then coating it with
copper coat or Yamabond.It would be great to have a Cometic MLS gasket to just
install and be done. I spoke to Cometic about this some years ago and they
wanted me to buy a large quantity (50 or 100, I forget) to justify the
development costs. I spoke with a couple of our TR part sellers, but since
they had invested in tooling for steel shim gaskets (or others), they were not
interested in pursuing this for their businesses. The current Cometic gaskets
do not account for the unshrouded intake valve.On a semi-related note, has
anyone considered or tried having cylinder sleeves pressed into a block to
eliminate the "wet" sleeves with the figure 8 gaskets at the bottom of the
sleeve? I am now racing a Honda S2000 and with my recent engine build I had
Darton steel sleeves pressed in to eliminate the damaged aluminum bores (also
87mm bore). There are Darton wet sleeves that completely eliminate the
aluminum bores and dry sleeves that are pressed into bored out aluminum bores.
I was thinking that the Darton wet sleeves could maybe work in the TR3/4 block.
If sleeves are pressed in, the tops can be decked level with the block and
eliminate the need to have the sleeves protrude above the block deck.

Wed, 20 Sep 2017 18:18:13 -0700Hi Jerry, I'm about to use Moss Motors supplied
89mm liners. For years we've used standard liners, milled the head for 10:1 and
higher street use. Carefully removing the lip on the head around the intake
valve and notching and indexing each liner to match material removed from the
cylinder head shrouding. Using 89mm liners (bigger bore) you will remove less
material from the head to raise compression. If liner projection is correct
we've used the steel shim head gasket BPNW have the correct gasket, be
conservative in removing material. The heagasket also needs to be trimmed to
compensate for material removed from the liner/intake port shroudind on the
head. In modifying the head gasket you do not want it to "hang into" the
combustion chamber or you will get detionation and gasket damage. Finally
carefully use contact cement and glue a single strand of .012" Copper wire into
the groove that is around the circumference of each cylinder of the gasket. I
think I have pictures or can take some this weekend. We've done this for many
years on lots of TR and Morgan race engines and have had great success and no
failures.t____________________________________________________________Actress
