Stalling and starting problems

[Larry C Leung]

Blown Intercooler end caps. Feel under the intercooler, especially at the
end caps. If there's oil, it's blown. You can try to regasket and reseal,
or replace, as I did, using a used one from Chris Semple. Would suggest
straping it with looong hose clamps to help prevent this happening again.
