MG TD TF 1500 - valve guide umbrella ???

Searching the archives for a part number ( Felpro )
I stumbled across various numbers. Varying from SS 30373 to SS 72522 and a few in between.
Any advice which is the correct to use ??

Thanks for your time,

Gerard, I don't have the number but as best I can remember, NAPA provided the seals used on a small block Chevrolet for my XPAG. They fit well and do the job. Check it out and see if their numbers match any of your numbers. Worth a try if you don't get any direct input.

More like small block Chrysler... and by small block, I mean 2.2/2.5L. Here is a link to them on Amazon.

Your machine shop will have to turn down the guides to accept them and cut down the oil deflectors to clear them.

Go to the archives and search on umbrella. There is a thread called "smoking again (still)" and I think you will find a great deal of excellent info......from others not myself. The outcome for me was that the car doesn't smoke at speed and only a bit if I sit at idle, I now just shut the engine off if I am going to idle for any length of time.

Thank you for the information Guy's . As mentioned in my post... I searched the archives for a few hours and came across a lot of info. But still no definite answer: such as ...... Use this type for inlet and type .. for exhaust. The info I found was conflicting with each other .

Thanks for your time,

Gerard, sorry, but I have never had a problem with the stock valve seals, when the guides are in good shape and fit properly.

I had one engine here a while ago that used the umbrella seals, and the valves kept sticking - not ENOUGH lubrication! It had steel guides. I replaced the exhausts with bronze and opened them up an additional .005, and he never had a problem.

Just my opinion.

Gerard, I have to agree with Tom.
I have had stock seals on my TD for 50 years and I don't burn oil (as long as the O rings are in good shape.) The original system is an umbrella system if assembled correctly and will prevent almost all the oil from going straight down the valve guides. What little will get there is I believe good for lubrication.
It is also possibly the most economical solution as well. The only time I have seen it not work right was on a friend’s car in Germany when the garage had installed the shroud upside down and it was burning copious amounts of oil The fix was to assemble it correctly and in a couple of hours it was no longer burning oil.

Teflon is the better choice.
Tom I hope you meant .0005" increase in guide diameter.
Valve stems seem to stick when too rich & not driven very hard, drive like you stole it & you will not have any sticking valves.

Gent's I have made up my mind . No Felpro and go back to "old fashioned standard :.. " new valves /guides / lifters.

Thanks for all the good idea's
