blocked 4agze /4age waterway, how to unblock

[cartledge_uk]

I'm rebuilding a 4agze and have a problem

On checking the waterways, spraying (WD40 etc) into it shows its blocked, I cleaned out the downward with a drill, but its still blocked.



somewhere on the dotted line.

Any ideas?

is that the oil hole?

edit: seems not http://www.philskies.net/library/peter/4age-block.jpg

does the metal between the cylinders join there?

[fixeruperer]

your just going to have to work at it with differant peice's of wire, is that the only blocked path ?, it mite be a good idea to get the block acid bathed and de-scaled.

is the bottem end together ?

Get the block chemically cleaned.

The block was stripped down (completely) and checked for flatness etc, and tanked.

Only on build up did I notice this was blocked. Its sludge, i'm 99% sure the H/g went on this engine its oily like deposits.

I solved it, mixture of wire, nitromors syringed in and carb cleaner. It unblocked it.

Wahoo, pistons going in this weekend

Cheers for the help

Glad you unblocked it ..

But i am curious does the head gasket actually have a hole in it that actually lines up with the said hole ? ..

'nitromors', paint stripper/remover?
Thanks. I'm surprised it was wasn't siamesed.

i had that problem when rebuilding the vermin, was a small coolant passage, couldnt un-block it and runs sweet with-out it.

Piece of mind there then, is a major pain in the ass to sort out (one of the reasons I stopped the rebuild for a while), but did it.


lexsmaz - yep it does
