MG TD TF 1500 - XPEG Block + TD round hole head + Gasket Choice

From reading the archives I think I am OK... but thought I had batter check.

I have and XPEG 1500 block # 2502 orginal to the car

I have later TD head #168422 with round holes

I replaced the head gasket after I blew it with the FT 1500 gasket Moss part# 290-200( I only just discovered I had a mismatched head and block).

I think this is round hole block + round hole head + round hole gasket.

My cooling should be fine ? I ask because A I blew the headgasket a while back because of coolant loss and I feel the car is running a little hot.

All three round hole, should be good to go.

Yes, I had banana hole head and block with round hole gasket... Bad, reduced water movement

Dave, the 1500 head gasket has a separate part number from the Late TD/TF gasket. Let's see what we hear from the folks who know about such things. Bud

The number 2 and 3 cylinders were "siamesed" on the XPEG block , so I would assume that the cylinder bores have been altered from the XPAG locations - I would think you would want to use a XPEG gasket rather than a XPAG gasket.

Don Harmer may chime in - I am sure he knows the answer. I would also think that the late TD/TF XPAG head would have a slight misalignment when fitted over the larger cylinder bores of the 1466 XPEG block.

I've done that once (at the customer's insistence...), and used the XPEG gasket. If you hold it up to the block you will see the fit, and then see where the siamese cylinders are NOT quite aligned right on the wrong head. Should work fine; I would use an appropriate head gasket cement on the gasket to be sure there are no water leaks. Also, check the studs carefully for thread stretch - they do, with poor torque the result.

Good luck finding an AEF118 head!

I just wanted to clarify my statement above about the cylinders. I realized after re-reading that I should have clarified it more by saying that #1 and #2 are siamesed as are #3 and #4 - there is no water passage between #1 and #2 or #3 and #4. There is a water passage between #2 and #3.

Hope that clarifies things.

Dave,
I have an XPAG head and an XPEG block (see in the archives "XPAG/XPEG What do we have?"). You will need to use a 1500 head gasket (which is sort of obvious, but we didn't know we had a mismatch until the smashed gasket gave us our first indication.) The water holes didn't line up perfectly, so I chamfered some of them in the head to allow less restricted passage of water. After a couple years, no problems.
Safety? Fast?

Thanks guys.looks like I am ok with the combination I have.

Hi Dave,

I can verify Scott's comments. The round water-holes in the XPEG block and gasket are further out than the round water-holes in the XPAG block and gasket.

Thanks - but probably not worth taking the head off just to chamfer the holes a little ?
