Engine: 2.0 Carb B200K/B200F: - Assembling top of engine....how tight?

davelarue · Oct 3rd, 2007, 19:26

Hi,
I just took of the 'top' (dunno what the terminology is) of my B20 engine to change the gasket under the valves (not the valvecover gasket). I think its called headgasket

Anyway, whats the procedure for putting the head back together again? How much do i tighten the bolts? And, in which order?

Sorry for my lack of terminology....i'm norwegian

Thanks a lot!

Cheers,
Dave

Is this the B20 all iron engine, like the one in the Amazon and 140?

First clean the surfaces and dry the bolt holes. Slowly tighten all bolts to 29 lb/ft, then to 58 lb/ft then warm up the engine. And tighten some more to 61-68 lb/ft. I had to remove and reinstall the rocker arm assembly (arms that push down the valves) a couple of times to get to the bolts and warm up etc.

The order looks like this seen from above:

Front 7 3 1 5 9 Back
8 4 2 6 10

So you start in the middle and go to-and-fro between front and back.
