anything sealer between jug and block

[NEONNIGHT34609]

i have seen where some people have leaks in this area. i know there is a gasket but does anyone coat there gasket with copper coat or Indian head sealer ? just wondering if this would prevent any potential leaks that might become an issue:-/

Dude did you try torque the head bolts down. Get a torque wrench!

i used a very thin coat of yamahabond and when i say thin i mean thin cant hurt

 

[J2PUISANT]

I just rebuilt my engine and did not use that. It does sound good. Maybe i wouldve used it. But truth be told after my third break-in cycle i retorqued the head bolts and no problems.

DUDE i have a torque wrench i rebuild diesel engines for a living. i am asking a question to see what others do. i am a fan of copper coat and Indian head sealer but i just dont wanna use it in a place where it might cause issues. its just a question my friend trust me there are a few torque wrenches in my tool box that get re calibrated every year.

hes talking about the base gasket not the head gasket atleast i think

 

[DUALSTROKE]

Only time I use sealer on the base gasket is if it is a copper gasket.Otherwise I just use the base gasket.If you feel better using it by all means go ahead,just go very very thin.

head bolts or jug bolts? i am taking about where the jug meets the block not where the head meets the jug.

most of the leaks there are caused by cheap aftermarket gaskets


if you just use a yamaha oem replacement you'll be fine. and retorque them after heat cycles

its the same "green" gasket

have you seen the ones that they make to bump up the compresion

 

[NEONNIGHT34609]

green base gaskets are no good ? i bought an ebay gasket set and the base gasket is green. i think the name was Namura ?

 

[hudack]

junk it and go to your local dealer and buy an oem base gasket mine was like 5$ and some change

yup, that's the green one, those gaskets are half the thickness of the stocker, which is enough to also change your port timing slightly

mine was a metal type kinda materal it didnt even look like a gasket

How do you get a tourq wrench on the jug bolts?

use a "crow's foot" for the jug bolts


and the vito's high compression kit i originally had, had a green base gasket that lasted a whole heat cycle before blowing.


the yamaha gaskets are kind of a metal material. its a lot better, and a lot thicker, i measured both one time and was fairly shocked at the difference
