my friend has a o-ring leak and we want to fix it with alumaseal.
how much you suppose to pour it in ?
we don't want to use crc block weld
thanks

 

any one?

 

None.

1. It's a "very" temporary fix.
2. It may clog perfectly good equipment; radiator, heater core, engine internals.
3. You may cause your engine to overheat if it fails and damage engine components that could have been reused in a rebuild.

But, if you don't care, use the whole bottle.

 

 

Everyone has different experiences with this fix. It may work it may not, but from all the post I have read the block weld has worked more than it hasn't. If your getting a reman. most of those parts I would replace anyway like the water pump, radiator with a good one, heater core, ect. If your going to rebuild it, then I wouldn't chance it.

 

There is a write up at on a website some where on it thats pretty good and explains how to do everything. Short hand you need to run a degreaser through the engine like simple green for three flushes. Then flush it through with clean water untill it is all out. At this point I don't remember how much to put in, but after you put it in (this is where my memory gets hazy) you run the engine for a while to circulate it around and then you let it sit for a day or two. From there it debates whether or not you should flush the system again or not. If I remember right they didn't, but if you worry about clogging things I don't think it would hurt anything as long as you let it sit first. I'll try to find the website for you to better explain it.

 

Found the site that goes through it step by step. Hope this helps you. http://www.scuderiaciriani.com/rx7/o-ring_fix.html
