Gaskets replacing

Post by snira »

Hey,
I am planning to start replacing gaskets at the upper part of the engine like - valve covers, LIM and I guess that SC too.
Now, because I have to order all parts in advance, because there is a lack of availability of parts for the rare L67 engine in my country, I need to know if except the gaskets that I mentioned above will I need to order more parts that needed to be replaced during this threatment?
Thanks.

you'll need a new set of o-rings for the injectors. If you re-use old ones there's a good chance gas will leak and result in a fire. There's a plastic coolant elbow that attaches to your LIM that you'll want to change as well.

Whenever you plan on doing some work on your car you should also skim the techinfo section of the site. I think there is one that specifically details doing this on an L36 but for the most part it's very similar. Basically ignore the UIM part since you have a supercharger instead of a plastic piece of leaking garbage on your engine.

Do you recommend on this set of o-rings? Is this complete set with everything I'll be needed?
