pre combustion chambers

[blownsmok4life]

I've looked every where and I'm having a hard time finding how to remove and replace the pre combustion chambers. If anyone can post a link or know anyone I can have it done by in western pa, it would greatly be appreciated. Thanks in advance, Ryan

First you need the heads off the block. Then remove the injectors. Now use a brass rod just large enough to snugly fit thru the injector port. Hit it with a hammer and they wil drop out of the head. Thats about it. Why do you want to replace them??? They are very expensive too.

mark them too iirc theres no allignment marks for them

Yes, they do have an alignment pin so they can only go in the heads one way.

I want to replace them because I'm currently rebuilding my engine and they have 3 or 4 cracks reaching just a hair before the compression ring line and i'm not taking those chances. Thanks for all of your replies.

I think you had better take a picture of what your saying and post it. The precups are flush with the head surface, they are no where near the compression rings. Are you seeing cracks in the pistons?

If the cracks are longer than 3/8 they need replaced.anything up to that is ok


Oldbull he means the comp ring on the gasket.
