[TR] Pushrods tr4 engine won't go back down.

[Jaap Dekker]

I have examined the head and although there's a lot of carbon junk in the 
cavities and on the valves, it looks like my problem might be something 
else. I took the dirtiest exhaust valve out and cleaned it with a wirebrush, 
it looks ok. The guides are bronze and there is little play. If the rest is 
like this I will put it back together and leave it like that.

When I looked into the cylinder liners I found what could be the reason for 
the excessive oil consumption. Number three and four had deep pitting where 
the gudgeon? pins rest in tdc on both sides. There are also deep scars 
running straight down. I suspect the circlips have failed.
I wiil have to dig into the bottom end now. I could use some advice on how 
to proceed.
I expect I will have to replace all liners and pistons?
There's 87 mm in there now. Would it hurt to go to 89 mm?

Regards,
Jaap Dekker

One other tip I just remembered - someone besides me came up with
this one, but I like it.  Use a long piece of stiff wire (like a coat
hanger straightened out), shove it down the hole parallel to the
pushrod and use it to hold the lifter in place while you pull out the 
pushrod.
