Customer: Yes , i do it myself in my friends shop he knows things about cars he is rebuilding carburators alternators starters etc.
JA: Anything else you want the mechanic to know before I connect you?
Customer: no


I'd suggest the next step is to do a compression test across all cylinders as they should all be within 10-15 psi of each other

as this will show if the gasket is still sealing correctly

if leaking then this can give issues with starting

The other thing to try is a head gasket / block test kit as these take a coolant sample and analyse it for any signs of combustion gas - if present this would indicate the head gasket is on its way out
