MG TD TF 1500 - Not a picture I wanted to take

The ride of shame :-(

I don't see any oil trail to the trailer,,

Better in one piece riding in shame than strewn all over the trailer. You'll have it on the road next week.

Heading home after a club lunch 60 miles south ...running about 65 into a hell of a head wind wind...started losing some power and I could hear some rattling under load.....oil pressure at a steady 55 and temp a steady 80. Pulled over....idling rough and car smoking at idle, Guys behind be said they never saw any smoke. Called my brother in law who lives about 8 miles from where we were and he came to the rescue. It's in the garage waiting now waiting for some investigation. Ughhhh.

LaVerne...

Probably a seized exhaust valve - happened to me a mile from home. Sounds almost exactly like the symptoms I had.

We are all hopeful it is a simple fix. Do keep us posted.

How much boost do you run, Laverne? And what altitude were you at when this happened. At 65 MPH with a 4.3 cwp, I'm guessing that you would be looking at abt. 3600 RPM. But with a head wind, that could be imposing a load on the engine. You might not have been developing sufficient torque. I'm thinking of a lean mixture/high cyl pressures = possible head gasket.

With a blower, I would be using premium fuel.

Do you use a solid gasket a or the standard one? When I was running a Marshall (abt. 8.5 lbs), I blew several head gaskets, 'till I switched to a solid one - problem solved.

Could the rattling have been heavy pinging? If so, sounds like a blown head gasket. A leak-down test should tell you exactly where the problem lies.

I had just a little time for it this morning. Pulled the valve cover and all is well with the valve train. A cold compression test revealed 59 and 60 lbs in the 3 and 4 cylinders. I removed the radiator cap to the sound of some pressure releasing.. most likley a blown head gasket.


It's making 7 lbs at full boost...changed out to a 4.55 rear end this winter and this is the first time I've had a chance to run it and I think I am going to like it a lot better than the 4.3... at about 5000 ft elevation or so Gord. A solid gasket may be in order...along with the ARP studs I have sitting on the shelf. I'm hoping it's just the gasket but even still I think it's time to build the engine with a few other trick parts internally as well. I probably won't be doing anything with it until I get bill's TF out of here and that's probably a month away.
MG LaVerne

That's a long time for the hornet to be down. What sort of trick parts? Are you gonna build it up similar to mine?

I'm thinking some appropriate pistons, rods, Len's cam, better water pump, lighten the flywheel a bit
MG LaVerne

I have the brown and gammon flywheel. I love it!
Alex Waugh

Those symptoms sound an awful lot like what I experienced last November on my TF-1500. The head gasket failed between 3 and 4, but mine had zero compression on those 2 cylinders.
Jack Long

LaVerne, I had Venolia out of california make my pistons,great job. Crower made my rods, those too are great. just a thought, I dont have any intrest in these companys just they did right by me.
TRM Maine

Thanks Tom, I look into it.
MG LaVerne

I have saenz rods and somebody's forged pistons but can't remember who's. I could look it up if you need me to.

LaVerne


you are not alone.

Last weekend the half shaft of the rear axle broke.

I'd emailed Dave Clark - hope he will answer soon.
