Headgasket trouble? 900 1997

Hi All,

I managed to remove both oil seals using a drill and two screws.

Pulling in the new ones was not easy, the intermediate being the most difficult.

I used a PVC pipe and a plastic film to make sure the lip was inward for the intermediate seal. The crank one instead seems to be shaped slightly different, therefore its installation has been easier.

Now, I have to hope they are working well.

I will finish the cleaning of some of the parts, and slowly start to re-assemble everything.

Torques:

In the pocket data booklet, I read the following, which is confusing to me?

- Main Bearing Cap: 110 Nm
- Connecting Rod Cap (Stage 1): 20 Nm
(Stage 2): angle-tighten 90°
- Camshaft cap: 20 Nm

Now, to me there are 5 caps that hold the camshaft, and when I have unbolted them, I could do that with the cylinder head on the bench, without big effort, which to me is a 20 Nm.

What do they mean by 'Main Bearing Cap' and 'Connecting Rod Cap'?

I could assume that the three central caps are what they call 'Connecting Rod Cap'? So those three should have 20 + 90°, while the remaining two on the edges 20 Nm.
If my thinking is correct, what is the 'Main Bearing Cap': 110 Nm?

- Water Pump: I cannot find the torque Specs
- Thermostat: I cannot find the torque Specs

Thank you!
Alessandro
