Sealing of Saddle Block in front of engine

[Brosky]

There was a question on another of my rebuilding threads that I felt rated it's own answer. I stopped at Her Majesty's this morning to see exactly what was on the Payen lower end gasket set and was surprised at what I saw.

The Payen set now uses a rubber, or most likely neoprene wedges to replace the wood. They are a bit of a pain to get in, but look like a really good seal when combined with the Goldblatt steel block.

And don't forget the position of the two side gaskets (under the block) in relation to the tangs facing forward. :laugh:

Excellant.

Yes, much nicer - the tree that was saved for the wedges will be used later when I print these photos and hang them next to my block so I don't forget anything.
Thanks Paul

I am not so sure that that is in fact a great improvement. The wood blocks swell up when exposed to oil and will seal very tight even if they are slightly damaged when installing them. If there is any damage to those rubber blocks, they are going to leak.

I took several engines apart to get a good supply of bits for the Herald and the wooden sealing blocks were very tight in all of them.

The problem with the saddle block leaking was never related to the wooden blocks it was almost always a result of someone stripping out the threads.

I got the rubber ones with my Payen kit. Unfortunately I had already installed the saddle block and could not get them to go in after the fact. I had to use wooden ones.

at first i was suprised to see wood blocks used in engine design, but now i like them. makes the whole car feel more rustic. then again, i've got a completly stock engine. keep up the good work.

also, all these pictures and info (and maybe even a bit more) will be on your website after you get done putting the "necessary" miles on your engine, right?

These are a very tight fit, trust me on that. If Erik is happy with them, after all of the TR6 engines that he's built, they're fine with me.

Flinky, I'm probably going to add two pages to my website. One for the engine machining and one for this assembly and quirky stuff. Who knows, maybe more, since these projects take on a life of their own.

Oh yeah, for those who missed the long supplier listing that I posted yesterday, Marc's website is here:
