most auto parts stores sell a kit with everything you need for this task. Including instructions.
Replace them. This can be done without removing the heads. Talk to your mechanic about this.
It is used to replace valve seals on many automotive engines without removing the cylinder head from the block.
yes heads need to be removed
well the valve seals are very difficult to do on the truck because of the fact I haven't seen a tool out there that can remove the valve spring with having the head still on this vehicle and working for suzuki i have had to take every head off but it may depend on what motor your working on 2.0 2.5 2.7
remove heads seal oil drain so seals dont fall in. then loosen and remove seals. replace and put engine back together. may need special mitsu. tools
Lots of labor but can be done without removing heads. If doing it yourself, not much cost -- seals plus valve cover gaskets. Shop cost if not doing it yourself -- prohibitive.
I suspect you are right. These can be replaced without removing the heads.
it would be better to go ahead and replace it, but if you dont its ok.
Yes, you remove the rockers, add air pressure in the cylinder through the plug hole and use a valve spring compressor to remove valve spring. You can now change the valve seal.
The Chevrolet 350 stock "O" ring valve seals attach to the valves not the heads but, yes the head assembly has valve seals.
can you change the injector tubes and seals without removing the cylinder head on a 1.7 cdti Vauxhall combi and is it much of a job
Because there stress out
