hey guys,
not your typical hotrodders engine here, but my daily driver blew a head gasket and i've put some work into it now to get going again.
i plan to turbo it later this year so i thought it'd be good to check out at least the top end before that. btw it's a 2.0l DOHC 4banger Ford, 1992 Ford Scorpio (similar to the merkur scorpio).
so while apart, i also spent all yesterday putting some effort into porting. then finding that #3 exhaust valve guide has shifted/dropped by about 3-4mm (about 0.150 inch)... see picture.
this IS a budget project and as such i'm wondering about the severity of this.. fix it or leave it, as long as i can get the valve seal on top of it? guide looks good inside and valve too.
from what i gather, some turbo engines have a groove in the top part of the valve guides securing them from dropping with some kind of lock ring. i say turbo engines because exhaust is much hotter and hence more risk of loosing the press fit of the guides.
so with the turbo in mind, maybe i should buy some lock rings and take a chance to make some grooves to secure the guides in place?
thanks for your advice,
