Runs normal and compression OK

A quick compression check may detect the head gasket possibility and preassure checking the manifold in place is relatively easy. Sounds like you have the winter to deal with and time is on your side to do the checks.

Hi Dave:

A4 ran fine all summer right up to winterizing. Last week, i did the "thumb" compression check (after putting copious MMO in cylinders) and all 4 checked out. So still hoping it was just a few episodes of slow starting w raw water thru-valve open.

I do plan to do manifold compression test now that Mo has sent steps. All the queries about exhaust were intended as another winter project that could have contributed to water in oil.

Still trying to think through if anti-siphon valve is a worthy addition. Even if manifold above waterline, does it do any harm?

thanks again
