Re: MG TA1932 in Germany - Blog - all problems and ...

Are you using standard T-type spark plug wires? The Pertronix/Powerspark type unit is not made to work with copper wire.

Re: XPAG rear oil seal modification

How long before it starts leaking? Or is this considered a permanent fix?

Re: non start when hot.

Heat soak vapor lock. Next time it will not hot start try using the choke to start. If that works, you do not need any modifications.

Re: priming the oil system prior to 1st restart

Chris, you say a fresh rebuild. You should use a smear of engine oil on the valve guides and around tappets. Pressurizing the system with oil from a pressure tank is fine, but some areas of the XPAG rely on splash lubrication that will only occur from the engine actually running for a while. It take...

There is a fairly simple test to check f...

Re: Rebuilding an SU carburettor

Steve is spot on about importance of fuel height. See article on page 29 in this link: http://www.namgar.com/images/uploads/Chapter_Newletters/Vintage_Racers_Newsletter30.1.pdf A much different and simpler approach to setting up SU H carbs. Air leaks through the (worn) throttle shaft cause all sorts...

Re: Suitable engine oils

Synthetic (thin) oil is the greatest thing since sliced bread for extremely cold climates. It also is great stuff for a modern engine with modern, sophisticated (clean) fuel injection, in any climate. Synthetic engine oil is not generally suggested for cars that are carbureted. Even a well set up SU...

Re: TC Brass Engine Tags

Is not the real question if or if not the Y Type engines are casting #24146, and if the tap is "forward" from the TC location-- which is in about the middle. Both Steves late TC block and my late TC block have the tap in the normal central TC location, and are 24146 blocks. Where is the tap in the 2...

Re: TC Brass Engine Tags

The "forward" drain tap on a 24146 block indicates a Y type engine in the Roger Wilson article. That is how I read it.

Re: TC Brass Engine Tags

Tom, would not TD9486 have been fitted with an XPAG with casting number 24445? Don says both his XPAG's are casting #24146. I think only some "very early" TD's were fitted with the TC 24146 block, and surely those few would have a 1949 casting date code.

Re: TC Brass Engine Tags

Don, In addition to the block casting number and the date stamp cast in the block, there is almost always another engine number stamped just above where the brass tag sits. Originally, that stamped number was identical to the number the brass tag displayed. It is not stamped very deeply, so can be d...

Re: TC Brass Engine Tags

Tom, if it an actual TC block, the C 9 indicates March '49. A slim chance it could also indicate a March '39 TB block. If it is a TB block it will have a different engine casting number than a TC. That block casting number is located above and to the right of the large "MG" Octagon, behind the gener...

Re: TC Brass Engine Tags

Many States titled cars by only the engine number when these cars were new and in the 50's. That could have been an incentive to keep the engine numbers consistent after the original engine was blown, and a running engine was found at the salvage yard to replace it.

Re: TC Brass Engine Tags

Thanks David. That makes perfect sense. Not sure where my erroneous idea of decades came from?

Tom, you were on to something, there.

Steve, If you look real close on my engine date code pic, you will see little hints of red paint under the "oil" coating.
