Hi guys, I was watching a video on a renesis rebuild from spain....His outer water jackets were too long and he cut them to fit in the groove....is this ok to do??

Thanks!

chepe

 

huh ?

 

if you start watching it at 11:04, he says he is resuing the old outer water jackets. so when he puts them on the housing....the water jacket has expanded. it is too big so he cuts it to make it fit in the groove.

Then again he is resuing his old ones.

 

ah so.

well step one, don't reuse the outers.

the outer rings do expand when you put petroleum jelly on them, so they do get longer, which is fine if you start with new, and assemble the engine.

if you do reuse, which is an option IF its a low mile/hour engine, ie race car. you can cut the seal, and use a dab of silicon to seal the junction. you do need to put the junction of the seal on the top somewhere where you can see it. if it starts leaking you want to be able to see it.

and just buy new seals, i haven't checked prices yet, but customarily its less expensive to buy the O ring set, which has ALL the coolant seals in it, than it is to buy all the water seals separate

 

I wouldn't do it. Not even with a gun pointed to my right ********.

 

Great Thank you all! I am learning how to rebuild my engine....this is the third time I rebuild one and every time i learn something different. I think I might be getting good at this

Thank you all very much!

 

so he is trying to save what ? 20 bux to risk of having a leak on a rebuild ?

I can see the reason why Rotary has such bad name. funny people does funny **** to it all the time.

 

true!
