Re: GLM manifold and risers- sealant needed?
I'm replacing manifolds and risers on a 2007 Volvo Penta 5.7 Gi-B. I'm using GLMs and was wondering if a sealant is required in the installation?
Thanks!
Ayuh,.... Welcome Aboard,.... I 2nd Senior B advice on the Gaskets....
With those GLM manifolds, When I bought a set,... The inner exhaust gasket surface was 'bout .010/ .020" Low...
They wouldn't seal, 'n I almost lost my motor....
So,....
Check yer's Closely with a straight edge, 'n feeler gages...
If it ain't Dead Flat,...
Run 'em to a Machine Shop, 'n they can flatten 'em for ya, reasonably quickly, 'n cheaply...
Way cheaper than a New Motor...
