MG TD TF 1500 - BLUE SMOKE GENERATOR

AFTER PULLING THE OIL PAN I FOUND WHAT WAS LEFT OF NO 2 PISTON. WITH HOLE LIKE THIS ITS LITTLE WONDER WE MADE LOTS OF SMOKE. DID NOT FIND ANY DAMAGE TO THE CYLINDER WALLS.

ENGINE RE-BUILD IS UNDER WAY WITH NEW HEPOLITE PISTONS.

UGLY !

My (personal) recommendation is that you use Deves rings. I have had problems with the usual supplier's rings not seating.

Tell us about your engine.

How many miles do you have on it now Colin?

I'm also curious if you saw these stampings in the head gasket

That last stamp would be the MOWOG stamp upside-down in case anyone cant read it.

That is correct. Made some comparrisons with it and the gasket that Moss supplies tonight.

The Moss version on a .060 over bore

And what I believe is an NOS MOWOG gasket

Not much meat between 2 and 3, however the MOWOG is a shocker, no wonder they blow.

Of interest to me was the fact that the Moss gasket would be unusable as it doesn't clear the bore.

With car apart and garage in disarray I cannot find the head gasket right now.

Engine is orig installation and has never been out of the car.
1954 TF 1250 cc. HDC 46/6688 XPAG/TF/35351
44,400 miles. Not driven too hard. It had 17,000 when we bought car 10 yrs ago.
I drove this car for a weekend in 1957.
I have only taken no.2 piston out so far. Rod journal looks really good and clean as do the bearings. Eng. has always been 70 psi on start-up,50 psi running, @ temp.

I am having new head gasket made. MM gaskets are too thin.
Have not done bore measurements yet. So , piston are TBD. I have a set of Std. A&E 4 ring, NOS from 1968.

Moss head gasket obtained last month on a +.040 engine. I'd prefer a Payen, but this looks find as far as clearing the combustion chamber.

I would like a bit more meat between the cylinders too.

I've used Moss-supplied gaskets for many years and a lot of hard miles. My engine is 30 over, 9.1:1 and never had one fail. If you're going bigger bore, you can always order a custom gasket. But I agree try to get some meat between those bores!
