Cracks on Primary chain guides
#1
![Default](/forum/images/icons/icon1.gif)
Hello everyone,
I've just pulled the cam covers off today to inspect the timing chain system & have discovered the following:
- Primary chain guides are cracked & therefore need replacing
- Secondaries are perfect & look as though theyve been done already with upgraded ones.
Ive checked out all the how-to's i can find so far & they all involve complete replacement. So my question is, am I able to replace JUST the primary guides & tensioners without all the other work involving locking the cams, removing the chains, removing the VVT components, etc? (So in other words, simply take timing cover off, replace primary guides & tensioners, put timing cover back on)
From what I can tell it can be done, but thought I'd get another opinion.

I would otherwise agree with replacing all components, but the cam locking tools are absurdly expensive to buy, so if I can avoid the need for them by only doing the forementioned then I will.

Replace the primary timing chains, guides and tensioners as the guides break and fall into the sump.
Use the proper tools and procedures as outlined here:

Note page 74 regarding the proper camshaft timing.
