Re: TC wire wheel restoration
As an added thought, the GB Pound is about $1.30, so the last set of new wire wheels shipped from the UK cost me about the same as rebuilding originals. I see little benefit in re-using original wire wheels, as the rims have probably been banged around and are no longer true. New wheels are availabl...

Re: Compression Ratios, rebores and head skimming
If you compare the two pictures above, you can quickly see the difference in head thickness, and therefore compression ratios. One indication is that the bottom of the spark plug hole has been cut away, leaving a sharp edge that can cause running-on. As a rule of thumb, if you can see the recessed a...

Re: ARP Flywheel Bolts Available - MGT Repair
Robert - the holes go right through the head, as you can see in the upper left bolt above. Yes, they are for lock wire. I don't want to tell you how to use lock wire, because it is devillishly hard to explain. I can refer you to the archives of the mg-cars.org.uk site, where there are numerous examp...

Those holes nearly doubled the price of the bolts, but I insisted on them.

ARP Flywheel Bolts Available - MGT Repair
Among the most highly-stressed fasteners in XPAG/XPEG engines are the four bolts that attach the flywheel to the crankshaft flange. These relatively small bolts, along with two tapered locating pins, are all that restrain a heavy 24-pound flywheel spinning at thousands of revolutions per minute. If ...

Re: Rebuilding XPAG 9204
I am certainly late to the party, but the first part of an earlier multi-part question was about whether there was any advantage to brass Welsh plugs over steel ones. I was replying to that, and nothing to do with flywheels. And my mythological reference was because I was trying to balance the fact ...

Re: Rebuilding XPAG 9204
I am sailing between Scylla and Charybdis, since I do sell brass Welsh plugs (see mgtrepair.net for details). I can confidently assure you that the steel plugs will and DO rust out internally - probably half of my orders every year come from people who write, "The steel core plug under the exhaust m...

Re: Crankshaft oil slinger problem.
The slot is just there to enable you to slip the slinger over the crank nose with the key in place. The pulley holds the slinger tight.

Re: XPAG Deck Height
There are a few reasons for this to happen. The engine may have been line bored, which effectively raises the crank in the block, pushing the pistons up. Also, given your high compression, the head and block habve no doubt been surfaced more than once, removing material from that area. Most pistons ...

If you go to the mg-cars.org site and search in the archives for "Pathe films" you will find a number of posts on the various Pathe films about MG cars from the 20's to the 50's. There are always new things to learn,.

Re: Compression Ratios, rebores and head skimming
Well, let's think for a moment about the down side of a high compression ratio. 1) need premium fuel 2) will have to advance timing to avoid pinging (plinking or pre-detonation); Distributor rebuild and advance re-curve will be beneficial 3) high-compression engines tend to run better at higher RPMs...

Re: TC sump baffles
The early TD (and I assume TC) sumps holds about 5 US quarts; later TD and TF sumps hold a quart more. Racers and spirited drivers would often install a larger sump on an early car, for better lubrication and cooling. Unfortunately, there can easily be mix-ups over time, in dipstick length and marki...

Re: Just when you think it's safe to go back into the water....
If one steel core plug is leaking, others will surely join the chorus, and start to leak without warning. Brass ones are without question the best, and will never leak.

Re: TC 5 speed box
In my experience, 92% of all TC boxes are just fine; I have probably stripped a dozen, and 10 of them needed nothing - NOTHING. The needles all were in spec, the gears were all fine, and the box needed only a good clean and re-assemble. A 5-speed does indeed change the feel of the car, but I think i...

Re: steel panel removal from wood
My experience (limited) is that not a lot of effort be put into removing the various pins, as the surrounding metal inevitably gets chewed up. I found that after using a sharp chisel to cut off the heads, I could easily pull the remaining shafts out with nippers or pliers.

Re: TC Bumpers
The original EXU bumpers were curved in profile from top to bottom, really smaller versions of the TD bumpers. Whenever you see the flat-bar bumpers, they are aftermarket. I knew one TC owner who added aftermarket bumpers because he claimed his wife, who drove the car, "can't drive worth a damn, and...

Re: TC Bumpers
First, do you have an EXU? That was the variant for import to the US, with special features like bumpers and turn signals. (The Guarantee Plate will be stamped "EXU" if it is.) I don't believe the EXU features were required by US law, but were thought of as features closer to the current US car. If ...

19/32"; you may have to cut it down a bit. The end nuts will need the rocker shaft clips removed.
